Description

Technical Field

[0001] This utility model relates to the field of turnover tooling technology, specifically a stacking turnover tooling for seat back panels. Background Technology

[0002] The car seat back panel is a key component located behind the seat, connecting the seat frame and the interior trim. It not only bears the structural strength of the seat, but also directly affects the aesthetics and functionality of the entire vehicle interior.

[0003] In the prior art, patent announcement number CN222157488U discloses an automotive seat accessory transfer device, including a vehicle body, an interior storage compartment, a cover adapted to the vehicle body that is rotatably connected to the interior of the storage compartment, an air pump installed inside the vehicle body, the output end of the air pump being connected to the storage compartment, and the input end of the air pump being connected to the outside of the vehicle body.

[0004] Seat back panels can be further transferred using specialized transport vehicles. However, due to their relatively thin and lightweight structure, they are highly susceptible to bending and deformation when loaded onto transport vehicles using multi-layer stacking. This deformation can affect not only the product's appearance but, in severe cases, its installation and usability. Therefore, special protective measures are necessary during actual transportation. To address this, a stacking and handling fixture for seat back panels is proposed. Summary of the Invention

[0005] The purpose of this utility model is to provide a stacking and turnover fixture for seat back panels to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stacking and turnover fixture for seat back panels, comprising a fixture frame, a ground wheel installed at the bottom of the fixture frame, a gray canvas covering the fixture frame, a partition frame fixedly installed inside the fixture frame, a positioning mechanism provided inside the partition frame, the positioning mechanism comprising a U-shaped air cushion fixedly installed inside the partition frame and a frame fixedly installed on the fixture frame, the inner surface of the U-shaped air cushion having nipples, an air pump fixedly installed on the frame, an inflation pipe connected to the air pump and communicating with the U-shaped air cushion, a pressure relief pipe connected to the bottom of the U-shaped air cushion, and a pressure relief component installed at the end of the pressure relief pipe.

[0007] Preferably, the bottom of the U-shaped air cushion is connected to a branch pipe, and a one-way valve is provided inside the branch pipe.

[0008] Preferably, bolts are connected to the frame, and the frame is fixedly installed to one side of the tooling frame by bolts.

[0009] Preferably, one end of the branch pipe is connected to the U-shaped air cushion, the other end of the branch pipe is connected to the inflation pipe, the air pump is fixedly installed on one side of the tooling frame via a frame, and the U-shaped air cushion is fixedly installed in the partition frame with structural adhesive.

[0010] Preferably, the pressure relief assembly includes a pressure relief valve body fixedly installed at the end of the pressure relief pipe. One end of the pressure relief valve body has a movable chamber, and the other end of the pressure relief valve body has a valve core groove. A spring is installed in the movable chamber, and a valve core body is slidably installed in the valve core groove. A sealing plate is fixedly installed at the end of the valve core body, and a T-shaped hole is provided on the valve core body.

[0011] Preferably, one end of the pressure relief pipe is connected to the pressure relief valve body, and the other end of the pressure relief pipe is connected to the U-shaped air cushion.

[0012] Preferably, a sealing ring is provided at the edge of the sealing plate, and the sealing plate abuts against the valve core slide groove port.

[0013] Preferably, the valve core body is slidably mounted on the pressure relief valve body via the valve core groove, one end of the spring is connected to the sealing plate, and the other end of the spring is connected to the inner wall of the movable chamber. The pressure relief valve body has a connection port, and the pressure relief valve body is connected to the end of the pressure relief pipe through the connection port. The tooling frame has an installation groove on its inner side, and the pressure relief valve body is installed in the tooling frame through the installation groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. In this application, after the air pump is started, it pumps air into the U-shaped air cushion, causing the air pressure inside the U-shaped air cushion to increase. As the air pressure inside the U-shaped air cushion increases, its surface protrusions will rise and abut against the surface of the seat back panel, thereby enabling the seat back panel to achieve flexible positioning within the partition frame and reducing the risk of damage to the seat back panel during transportation.

[0015] 2. In this application, after the seat back panel is transported to the designated position, the valve core body can be pressed to allow it to enter the movable chamber. After the valve core body enters the movable chamber, both ends of the T-shaped hole will be exposed inside the movable chamber, thereby connecting the pressure relief pipe to the outside and expelling the air from the U-shaped air cushion, causing the U-shaped air cushion to contract. After the U-shaped air cushion contracts, the seat back panel inside the partition frame will become loose, making it easier for workers to remove the seat back panel from the partition frame.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: As Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a stacking and turnover fixture for seat back panels, including a fixture frame 1, a ground wheel 3 installed at the bottom of the fixture frame 1, a gray canvas 4 wrapped on the fixture frame 1, a partition frame 2 fixedly installed inside the fixture frame 1, a positioning mechanism 5 provided inside the partition frame 2, and a pressure relief component 6 installed at the end of the pressure relief pipe 507.

[0020] Specifically, the seat back panel can be placed inside the partition frame 2, and the tooling frame 1 can be moved by the ground wheels 3 to the assembly position of the seat back panel during transport. The positioning mechanism 5 can flexibly position the seat back panel inside the partition frame 2, reducing the risk of injury during the transport of the seat back panel. The pressure relief component 6 can release air from the U-shaped air cushion 501, causing the U-shaped air cushion 501 to contract, making it easier for workers to remove the seat back panel from inside the partition frame 2.

[0021] Example 2: Figure 3 and Figure 4As shown, the positioning mechanism 5 includes a U-shaped air cushion 501 fixedly installed in the partition frame 2 and a frame 506 fixedly installed on the tooling frame 1. The inner surface of the U-shaped air cushion 501 is provided with nipples 508. An air pump 505 is fixedly installed on the frame 506. An inflation pipe 504 is connected to the air pump 505 and is connected to the U-shaped air cushion 501. A pressure relief pipe 507 is connected to the bottom of the U-shaped air cushion 501. A branch pipe 503 is connected to the bottom of the U-shaped air cushion 501 and a one-way valve 502 is provided in the branch pipe 503. Bolts are connected to the frame 506 and the frame 506 is fixedly installed on one side of the tooling frame 1 by bolts.

[0022] Specifically, when the operator starts the air pump 505, the air pump 505 begins to work, continuously pumping compressed air into the internal cavity of the U-shaped air cushion 501 through the connecting pipeline. As air is continuously injected, the air pressure inside the U-shaped air cushion 501 gradually increases, causing it to expand and deform. Under the action of increased air pressure, multiple protrusions 508 evenly distributed on the surface of the U-shaped air cushion 501 will simultaneously bulge outwards, and these protruding protrusions 508 will closely abut against the contact surface of the seat back panel. Through this design, the seat back panel can achieve multi-point flexible positioning within the partition frame 2, which not only ensures the stability of positioning but also avoids the damage that may be caused by rigid contact, thereby effectively reducing the risk of damage to the seat back panel due to vibration or collision during transportation. In addition, the device is equipped with a one-way valve 502 as a safety guarantee. When a U-shaped air cushion 501 is accidentally damaged and leaks air, the one-way valve 502 will automatically close, forming a one-way barrier to prevent the compressed gas in other normally operating U-shaped air cushions 501 from leaking back through the connecting pipeline, ensuring that other air cushions can continue to maintain normal working pressure and guaranteeing the reliability of the entire positioning system.

[0023] Example 3: Figure 3 and Figure 5 As shown, the pressure relief assembly 6 includes a pressure relief valve body 601 fixedly installed at the end of the pressure relief pipe 507. One end of the pressure relief valve body 601 has a movable chamber 602, and the other end of the pressure relief valve body 601 has a valve core slide groove 606. A spring 603 is installed in the movable chamber 602. A valve core body 605 is slidably installed in the valve core slide groove 606. A sealing plate 604 is fixedly installed at the end of the valve core body 605. A T-shaped hole 607 is opened on the valve core body 605. One end of the pressure relief pipe 507 is connected to the pressure relief valve body 601, and the other end of the pressure relief pipe 507 is connected to the U-shaped air cushion 501. A sealing ring is provided at the edge of the sealing plate 604, and the sealing plate 604 abuts against the port of the valve core slide groove 606.

[0024] Specifically, the spring 603 provides thrust to the sealing plate 604, causing it to fit tightly against the valve core slide groove 606 port, thereby preventing the pressure relief pipe 507 from venting.

[0025] After the seat back panel is in place, the valve core body 605 can be pressed to allow it to enter the movable chamber 602. After the valve core body 605 enters the movable chamber 602, both ends of the T-shaped hole 607 will be exposed inside the movable chamber 602, thereby connecting the pressure relief pipe 507 with the outside, expelling the air from the U-shaped air cushion 501, and causing the U-shaped air cushion 501 to contract.

[0026] After the U-shaped air cushion 501 retracts, the seat back panel inside the partition frame 2 will loosen, making it easier for workers to remove the seat back panel from the partition frame 2.

[0027] Working principle: First, place the seat backrest inside the partition frame 2. After placement, activate the air pump 505. Activation of the air pump 505 will pump air into the U-shaped air cushion 501, increasing the air pressure within it. This increased pressure causes the protrusions 508 on the surface of the U-shaped air cushion 501 to rise and press against the seat backrest surface, flexibly positioning the seat backrest within the partition frame 2 and reducing the risk of injury during transport. Furthermore, if one U-shaped air cushion 501 ruptures and leaks air, the one-way valve 502 can prevent air leakage from other U-shaped air cushions 501. Spring 603 provides thrust to sealing plate 604, pressing it against the valve core groove 606 port to prevent pressure relief pipe 507 from venting. After the seat back panel is in place, valve core body 605 can be pressed to enter movable chamber 602. After valve core body 605 enters movable chamber 602, both ends of T-shaped hole 607 will be exposed in movable chamber 602, allowing pressure relief pipe 507 to communicate with the outside, venting air from U-shaped air cushion 501 and causing U-shaped air cushion 501 to contract. After U-shaped air cushion 501 contracts, seat back panel in partition frame 2 will loosen, allowing workers to remove seat back panel from partition frame 2.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
