Description

Technical Field

[0001] This invention belongs to the field of child seat technology, and relates to a 360-degree rotating child safety seat and a frame processing device. Background Technology

[0002] In the field of child travel safety, child safety seats, as an important piece of equipment to ensure the safety of children traveling in vehicles, have always received widespread attention. Currently, there are many types of child safety seats on the market, but they still have many shortcomings in terms of functionality and structural stability.

[0003] The connection between the various components of the frame is not stable enough and is prone to loosening. For example, the connecting plate is directly welded to the bottom of the frame, which is prone to weld failure after long-term use. This not only affects the overall stability of the seat, but may also pose a potential threat to the safety of children.

[0004] Meanwhile, the processing quality of child safety seat frames directly affects the performance and safety of the seats. Existing child safety seat frame processing equipment has limitations in processing precision and efficiency. In the bending process, some equipment struggles to precisely control the bending angle and shape of the steel pipes, resulting in significant dimensional deviations in the bent tube frames, failing to meet the design requirements of the seat frame and consequently affecting the assembly precision and overall quality of the seat. In the stamping process, existing equipment often requires multiple processes and multiple machines to complete the stamping of rectangular holes and the bending of extension pieces, which is not only inefficient but also makes it difficult to ensure consistent stamping and bending quality. For example, when stamping rectangular holes, problems such as hole position deviation and burrs on the hole edges are prone to occur; when bending extension pieces, the bending angle and shape are difficult to control precisely, failing to effectively limit the connection plates and reducing the connection strength and stability of the frame.

[0005] Therefore, we proposed a 360-degree rotating child safety seat and frame processing device to solve the problems mentioned above. Summary of the Invention

[0006] In view of this, in order to solve the above problems, the present invention provides a 360-degree rotating child safety seat and a frame processing device.

[0011] Solid PP material provides support and cushioning, while the extension sheet and connecting plate work together to enhance the connection stability. The support rod and 360-degree rotation setting improve stability and flexibility of use.

[0012] A rotating child safety seat frame processing device, used for processing the aforementioned frame, including:

In conjunction with the guide wheel, the steel pipe is bent to form a pipe frame.

[0018] The stamping mechanism, mounted on the worktable, includes two sets of cutters slidably mounted on the worktable and a drive assembly that works in conjunction with the limiting assembly. The drive assembly uses the power of the limiting assembly to drive the cutters toward the steel pipe to stamp the rectangular hole.

[0026] The limiting component includes:

[0027] Two first guide rods are slidably mounted on one side of the rotating plate;

[0028] The push plate is fixedly installed at the outer ends of the two first guide rods;

[0029] The second hydraulic cylinder is fixedly installed at the bottom of the rotating plate, and its output end is fixedly connected to the push plate.

[0030] The insertion rod is set on one side of the push plate and is adapted to the inner diameter of the steel pipe. The bottom of the insertion rod is provided with a clearance groove corresponding to the rectangular hole.

[0031] The second hydraulic cylinder drives the push plate to move, so that the insertion rod is inserted into the inner diameter of the steel pipe to limit its movement.

[0032] A sliding column is slidably installed through one side of the push plate. A limiting ring is fixedly sleeved on the outer wall of the sliding column. A first spring is sleeved on the outer wall of the sliding column. The two ends of the first spring abut against the outer end of the sliding column and one side of the push plate through spring seats respectively. The insertion rod is fixedly installed on one side of the sliding column. A groove is opened on one side of the sliding column. A first limiting block that cooperates with the groove is fixedly installed on the top of the worktable.

[0033] The first limiting block cooperates with the groove to limit the insertion rod.

[0034] The driving component includes:

[0035] Two sets of first wedges are slidably mounted on the top of the worktable;

[0036] The connecting strip is L-shaped, and the same connecting strip is fixedly installed on one side of the first wedge block in each group. One side of the connecting strip is used in conjunction with the push plate.

[0037] Two fixing strips are fixedly installed on the top of the workbench;

[0038] The second guide rod is slidably mounted through one side of the fixed strip and is used in conjunction with the first wedge block;

[0039] A sliding bar is slidably mounted on the top of the worktable, and the other ends of the two second guide rods are fixedly mounted with the same sliding bar.

[0040] The cutter is fixedly installed on one side of the sliding bar;

[0041] The second spring is sleeved on the outer wall of the second guide rod, and its two ends respectively abut against one side of the fixing bar and the other end of the second guide rod through spring seats;

[0042] The push plate moves, driving the connecting bar to push the first wedge block, and the first wedge block abuts against the second guide rod to drive the cutter to punch.

[0043] The flange assembly includes:

[0044] The third guide rod is slidably mounted on the top of the cutter.

[0045] The lifting plate is slidably installed inside the cutter.

[0046] The third spring is sleeved on the outer wall of the third guide rod, and its two ends abut against the top of the cutter and the top of the third guide rod respectively through spring seats;

[0047] The mounting base is fixedly installed on the top of the workbench, corresponding to the cutter.

[0048] The second wedge is fixedly installed on one side of the fixed base and is used in conjunction with the third guide rod.

[0049] When the cutter moves, the third guide rod contacts the second wedge block, driving the lifting plate to bend the extension piece.

[0050] Multiple sliding blocks are slidably installed on one side of the inner clamping block, and the other end of the multiple sliding blocks is fixedly connected to the outer clamping block. A fourth spring is fixedly connected between the sliding block and the inner clamping block. A connecting frame is fixedly installed on the outer clamping block, and one side of the connecting frame is fixedly connected to the output end of the first hydraulic cylinder. Two second limiting blocks that cooperate with the inner clamping block are fixedly installed on the top of the worktable.

[0051] In this process, after the clamping block holds the steel pipe, it pushes the frame away from the insert rod.

[0052] When the insert rod is inserted into the steel pipe, the clearance groove corresponds to the position of the rectangular hole to prevent deformation during bending.

[0053] The manufacturing method for a 360-degree rotating child safety seat frame, using the aforementioned manufacturing equipment, includes the following steps:

[0057] S4. Start the second hydraulic cylinder to extend, drive the push plate to move, drive the cutter to approach the steel pipe through the connecting bar and the first wedge block, punch the rectangular hole, and at the same time the third guide rod contacts the second wedge block to drive the lifting plate to bend the extension piece.

[0058] S5. Start the first hydraulic cylinder to extend, drive the clamping block to push the skeleton away from the insert rod, and complete the processing.

[0085] like Figures 1-3 As shown, the 360-degree rotating child safety seat consists of a base 1 and a seat 2. The seat 2 is rotatably mounted on the top of the base 1, allowing the seat 2 to rotate 360 ​​degrees relative to the base 1, making it convenient for parents to adjust the seat 2's orientation as needed. The base 1 is integrally injection molded from high-strength engineering plastic, with a circular rotating track at its top containing ball bearings to ensure smooth rotation of the seat 2. The seat 2 includes a frame 4, which is covered with solid PP material. This material has good toughness and impact resistance, effectively protecting the child's safety during vehicle travel. A support rod 3 is located on one side of the base 1 to enhance the stability of the seat 2.

[0086] A connecting plate 5 is welded to the bottom of the frame 4, and a rectangular hole 6 is opened at the bottom of the frame 4, with an extension piece 7 inside the rectangular hole 6. One end of the connecting plate 5 is fixed between the frame 4 and the extension piece 7 by welding, forming a stable connection structure. This not only enhances the overall strength of the frame 4, but also facilitates the installation and disassembly of the seat 2 and the base 1. The frame 4 adopts a tube frame 402 formed by bending steel pipe 401.

[0087] like Figures 4-10 As shown, a 360-degree rotating child safety seat frame processing device is used to process the aforementioned frame 4. The device includes a housing 8, with a worktable 10 fixedly mounted on the top of the housing 8. Two clamping blocks 15 are mounted on the top of the worktable 10 for clamping sliding blocks 41. A first hydraulic cylinder 16 is mounted on the top of the worktable 10, and its output end is connected to the outer clamping block 15. The clamping force and position of the clamping block 15 can be precisely adjusted through hydraulic system control. Multiple sliding blocks 41 are slidably mounted on one side of the inner clamping block 15, and the other ends of the sliding blocks 41 are fixedly connected to the outer clamping block 15. A fourth spring 42 is fixedly connected between the sliding blocks 41 and the inner clamping block 15 to provide a certain degree of reset. A connecting frame 43 is fixedly mounted on the outer clamping block 15, and one side of the connecting frame 43 is fixedly connected to the output end of the first hydraulic cylinder 16. Two second limiting blocks 44, which cooperate with the inner clamping block 15, are fixedly installed on the top of the worktable 10 to limit the movement range of the inner clamping block 15. The steel pipe 401 can be pushed out and clamped by the first hydraulic cylinder 16.

[0088] Two guide wheels 17 are also fixedly installed on the top of the worktable 10 to guide the steel pipe 401. The design of the guide wheels 17 enables the steel pipe 401 to maintain a stable movement trajectory during processing, thereby improving processing accuracy.

[0089] The bending mechanism is mounted on the workbench 10 and includes two rotating plates 11, a third hydraulic cylinder 45, and a limiting assembly. The limiting assembly is used to limit the steel pipe 401, ensuring that the steel pipe 401 does not deviate during the bending process. The third hydraulic cylinder 45 is fixedly installed at the bottom of the workbench 10, and its output end is fixedly connected to the sliding seat 20. The sliding seat 20 is rotatably connected to the rotating plates 11 via a connecting rod 21. When the third hydraulic cylinder 45 extends or retracts, it drives the rotating plates 11 to rotate. The rotation of the rotating plates 11, in conjunction with the action of the two guide wheels 17, can bend the steel pipe 401 by 90 degrees to form the required pipe rack 402 structure.

[0090] The stamping mechanism is also mounted on the worktable 10, including two sets of cutters 31 slidably mounted on the worktable 10 and a drive assembly that works in conjunction with the limiting assembly. The drive assembly uses the power from the limiting assembly to drive the cutters 31 closer to the fourth spring 42, stamping the rectangular hole 6. During the stamping process, the flanging assembly bends the extension piece 7, forming a groove that limits the connecting plate 5. This limits the connecting plate 5, and the extension piece 7 increases the contact area between the frame 4 and the connecting plate 5, improving welding strength and enhancing the overall stability of the seat 2.

[0091] Specifically, the bending mechanism also includes two rotating shafts 18 that pass through and are fixed to the top of the worktable 10. The rotating shafts 18 are coaxial with the guide wheel 17 to ensure that the guide wheel 17 can rotate stably. The limiting assembly includes two first guide rods 22 that are slidably installed on one side of the rotating plate 11. The outer ends of the two first guide rods 22 are fixedly installed with the same push plate 12. A second hydraulic cylinder 19 is fixedly installed at the bottom of the rotating plate 11, and its output end is fixedly connected to the push plate 12. One side of the push plate 12 is provided with an insertion rod 13 that matches the inner diameter of the steel pipe 401. The bottom of the insertion rod 13 is provided with a clearance groove 23 corresponding to the rectangular hole 6. During the bending process, the push plate 12 is driven to move by the second hydraulic cylinder 19, and the insert rod 13 is inserted into the steel pipe 401, so that the position of the relief groove 23 corresponds to the position of the rectangular hole 6, ensuring that the steel pipe 401 will not deform during bending and stamping. At the same time, the push plate 12 can be used to center the steel pipe 401 and make the relief groove 23 correspond to the rectangular hole 6 to be stamped. The bottom of the rotating plate 11 is also connected to the support leg 14 by bolts, and the bottom of the support leg 14 is equipped with rollers, which can not only support the rotating plate 11, but also not hinder the rotation of the rotating plate 11.

[0092] A sliding column 24 is slidably mounted through one side of the push plate 12. A limiting ring 26 that abuts against the push plate 12 is fixedly sleeved on the outer wall of the sliding column 24. A first spring 27 is sleeved on the outer wall of the sliding column 24. The two ends of the first spring 27 abut against the outer end of the sliding column 24 and one side of the push plate 12 respectively through spring seats. An insert rod 13 is fixedly mounted on one side of the sliding column 24, and a groove 25 is formed on one side of the sliding column 24. A first limiting block 28 that cooperates with the groove 25 is fixedly mounted on the top of the worktable 10. The first limiting block 28 limits the insert rod 13, which facilitates subsequent pressing using the power of the second hydraulic cylinder 19 to move the sliding column 24.

[0093] The drive assembly includes two sets of first wedges 35 slidably mounted on the top of the worktable 10. Each set of first wedges 35 has a connecting strip 34 fixedly mounted on one side. The connecting strip 34 is L-shaped and engages with the push plate 12 on one side. Two fixing strips 29 are fixedly mounted on the top of the worktable 10. A second guide rod 32, engaging with the first wedges 35, is slidably mounted through one side of each fixing strip 29. A sliding strip 30 is fixedly mounted on the other end of each of the two second guide rods 32, and the sliding strip 30 is slidably mounted on the top of the worktable 10. Two cutters 31 are fixedly mounted on one side of the sliding strip 30. A second spring 33 is sleeved on the outer wall of the second guide rod 32. When the push plate 12 moves, it pushes the first wedges 35 to move via the connecting strip 34, thereby pushing the sliding strip 30 and the cutters 31 to perform a stamping action. During the reset process, the second spring 33 drives the cutters 31 to reset and move.

[0094] The flanging assembly includes a third guide rod 37 that is slidably mounted through the top of the cutter 31, and a lifting plate 36 that is slidably mounted inside the cutter 31. A third spring 38 is sleeved on the outer wall of the third guide rod 37, and the two ends of the third spring 38 abut against the top of the cutter 31 and the top of the third guide rod 37 respectively through spring seats. A fixed seat 39 corresponding to the cutter 31 is fixedly mounted on the top of the worktable 10, and a second wedge 40 that cooperates with the third guide rod 37 is fixedly mounted on one side of the fixed seat 39. During the stamping process, when the cutter 31 approaches the extension piece 7, the third guide rod 37 will contact the second wedge 40 and be squeezed, thereby pushing the lifting plate 36 to bend the extension piece 7, forming a positioning groove that limits the connection plate 5. At the same time, a controller 9 is also provided on one side of the housing 8, which controls the extension and retraction of each hydraulic steel.

[0095] When in use, turn on the power to the device, place the steel pipe 401 inside the two clamping blocks 15 and on the multiple sliding blocks 41, start the first hydraulic cylinder 16 to retract, the first hydraulic cylinder 16 can pull the connecting frame 43 to move during the retraction process, the movement of the connecting frame 43 can drive the outer clamping block 15 to move, the outer clamping block 15 can drive the inner clamping block 15 to move inward at the same time through the fourth spring 42 until the inner clamping block 15 abuts against the two second limit blocks 44;

[0096] When the second hydraulic cylinder 19 is retracted, it can drive the push plate 12 to move closer to the rotating plate 11. During the movement of the push plate 12, it can drive the insertion rod 13 to move through the sliding column 24, so that the insertion rod 13 is inserted into the steel pipe 401.

[0097] The first hydraulic cylinder 16 is activated and continues to retract, which can drive the outer clamping block 15 to move closer to the inner clamping block 15 to clamp the steel pipe 401.

[0098] When the third hydraulic cylinder 45 is extended, the connecting rod 21 can drive the rotating plate 11 to rotate on the rotating shaft 18. During the rotation, the guide wheel 17 bends the steel pipe 401, so that the steel pipe 401 forms the pipe rack 402. After bending, the first limit block 28 is located in the groove 25, and one end of the connecting strip 34 is located on the outside of the push plate 12.

[0099] When the second hydraulic cylinder 19 is extended, the push plate 12 is driven away from the rotating plate 11 during the extension process. Since the first limiting block 28 is located in the groove 25, it can limit the sliding column 24. At this time, the movement of the push plate 12 will not drive the insertion rod 13 to move. During the movement of the push plate 12, it can push the connecting strip 34 to move. During the movement of the connecting strip 34, it can drive the first wedge 35 to move. The movement of the first wedge 35 can abut against the second guide rod 32, so that the second guide rod 32 moves within the fixed strip 29. During the movement of the second guide rod 32, it can use the sliding strip 30 to drive the two cutters 31 to approach the steel pipe 401. During the approach process, it can punch the steel pipe 401 to form a rectangular hole 6.

[0100] When the third guide rod 37 contacts the second wedge block 40, the second wedge block 40 can drive the third guide rod 37 to move downward. The downward movement of the third guide rod 37 can drive the lifting plate 36 to move downward, and can bend the cutting position downward to form a vertical extension piece 7.

[0101] The second hydraulic cylinder 19 is activated to retract and drive the push plate 12 to reset and move. The second guide rod 32 can reset and move under the force of the second spring 33, driving the sliding bar 30 and the two cutters 31 to reset and move until the cutters 31 are away from the steel pipe 401. The first hydraulic cylinder 16 is activated to extend. During the extension of the first hydraulic cylinder 16, the two clamping blocks 15 can be driven to move forward. The inner clamping blocks 15 can be used to push the pipe rack 402 to move until the pipe rack 402 is disengaged from the two insert rods 13. Then, the third hydraulic cylinder 45 is activated to retract and the second hydraulic cylinder 19 is activated to extend in sequence, preparing for the next processing.
