Description

Technical Field

[0001] This invention belongs to the field of automotive handle bending technology, specifically a bending device and method for an automotive seat adjuster handle. Background Technology

[0002] Modern car seats are equipped with a manual seat back tilt adjuster. The lever of the universal adjuster is a Z-shaped plate structure. After installation and fixing, the handle is close to the frame under the seat. Before bending, the car seat adjuster handle is often in the shape of a long metal plate.

[0003] Currently, when bending the handle of a car seat adjuster, it is often necessary to bend the handle by placing a long metal plate on a bending machine and bending it into an L-shape. Then, the position of the long metal plate is adjusted and it is bent again into a Z-shape, thus achieving the bending effect of the car seat adjuster handle. However, this method of producing car seat adjuster handles requires position adjustment of the L-shaped handle during the bending process, which reduces the bending efficiency of the device. Therefore, a bending device and method for car seat adjuster handles is proposed to solve the problems mentioned in the background art. Summary of the Invention

[0004] To address the problems mentioned in the background section, this invention provides a bending device and method for a car seat adjuster handle, which solves the problem that existing devices require adjustments to metal plates when turning the car seat adjuster, thus reducing production efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bending device for a car seat adjuster handle, comprising a support base, a Z-shaped groove, a magnet block, and a through hole. A support frame is fixedly connected to the top of the support base, and an electric hydraulic rod is fixedly connected to the top of the support frame. A second limiting rod is fixedly connected to the front and rear ends of the lower surface of the middle part of the support frame. A double-headed inclined block is sleeved on the surface of the second limiting rod. A second baffle and a first baffle are fixedly connected to the front and rear ends of the top of the support base. A metal long plate body is placed on the top of the support base. A first inclined block and a second inclined block are movably engaged in the inner cavities of the front and rear ends of the support base, respectively. A first limiting rod is movably connected to the inner cavity of the second inclined block. A second tension spring is sleeved on the outer surface of the first limiting rod. A first tension spring is provided on the side of the first inclined block away from the second limiting rod. A blocking mechanism is movably engaged in the middle of the top of the support base.

[0006] Preferably, the blocking mechanism includes a third inclined block, which is movably engaged in the inner cavity of the support base. Third limiting rods are sleeved on both sides of the third inclined block, and springs are sleeved on the outer surface of the third limiting rods.

[0007] Preferably, one end of the bottom of the electric hydraulic rod passes through the support frame and is fixedly connected to the top of the double-headed inclined block. The two ends of the bottom of the double-headed inclined block are respectively located directly above the first inclined block and the second inclined block, and one end of the bottom of the second limiting rod is located directly above the metal long plate body.

[0008] Preferably, the metal long plate body is located between the second baffle and the first baffle, and the Z-shaped groove is provided on the top of the support base.

[0009] Preferably, the top of the first inclined block is inclined on the side near the double-headed inclined block, and the two ends of the first tension spring are fixedly connected to the support base and the first inclined block, respectively.

[0010] Preferably, the middle part of the top of the second inclined block is inclined and is pressed together with the rear end of the bottom of the double-headed inclined block. Both ends of the first limiting rod are fixedly connected to the support base, and both ends of the second tension spring are fixedly connected to the support base and the second inclined block, respectively.

[0011] Preferably, the length of the end of the double-headed inclined block located directly above the first inclined block is longer than the length of the end of the double-headed inclined block located directly above the second inclined block. The upper and lower sides of the through hole are respectively opened in the middle of the first inclined block and inside the support base. The end of the double-headed inclined block located above the first inclined block is movably connected to the inner cavity of the through hole.

[0012] Preferably, the magnet is located inside the support base on the side away from the second baffle and is fixedly connected to the inner cavity of the support base, and the top of the magnet is in contact with the bottom of the metal long plate body at the end away from the second baffle.

[0013] Preferably, the third inclined block is located on the side above the support base and is inclined, with the inclined surface of the third inclined block tilting towards the side closer to the first inclined block. The inclined surface of the third inclined block cooperates with the metal long plate body. The top of the third limiting rod is fixedly connected to the support base. The top and bottom of the spring are fixedly connected to the third inclined block and the third limiting rod, respectively.

[0014] Preferably, a method for bending a car seat adjuster handle includes the following steps: S1. First, the operator places one side of the metal long plate body between the first baffle and the second baffle. At the same time, the bottom of the metal long plate body away from the second baffle will be attracted by the magnet. Then, the operator operates the electric hydraulic rod, which will cause the double-headed inclined block to move downward. This causes the double-headed inclined block to first squeeze the first inclined block, and the side of the first inclined block close to the metal long plate body to squeeze the metal long plate body, thus bending the metal long plate body into an L shape. As the electric hydraulic rod continues to operate, the bottom of the double-headed inclined block, which is above the second inclined block, will squeeze the second inclined block. At this time, the second inclined block will squeeze the bent end of the metal long plate body under the limiting action of the first limiting rod and the support base, thus bending the metal long plate body into a Z shape. Finally, the bent metal long plate body will fall through the Z-shaped groove. S2. During the first bending of the metal plate body, the side of the metal plate body closest to the third inclined block will press against the third inclined block, causing the third inclined block to move downwards. After the metal plate body completely passes the third inclined block, the third inclined block will reset under the limiting action of the spring force and the third limiting rod. When the second inclined block bends the metal plate body subsequently, the second inclined block will press against the metal plate body and push the first inclined block to move away from the second baffle. At this time, the third inclined block prevents it from moving away from the second baffle, thus making the device more stable during operation.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention utilizes the cooperation of structures such as a double-headed inclined block, a first inclined block, an electro-hydraulic rod, and a second inclined block to enable the device to quickly bend a long metal plate, thereby improving efficiency. Operating the electro-hydraulic rod causes the double-headed inclined block to move downwards, first pressing against the first inclined block. The side of the first inclined block closest to the long metal plate then presses against the plate, bending it into an L-shape. As the electro-hydraulic rod continues to operate, the bottom of the double-headed inclined block, positioned above the second inclined block, presses against the second inclined block. At this point, the second inclined block, under the limiting action of the first limiting rod and the support base, presses against the bent end of the long metal plate, bending it into a Z-shape. Finally, the bent long metal plate falls through the Z-shaped groove, thus solving the problem of needing to adjust the long metal plate during bending and improving bending efficiency. This invention, through the cooperation of the third inclined block, the third limiting rod, and the spring, makes the device more stable during operation. When the metal plate body undergoes its first bend, the side of the metal plate body closest to the third inclined block will press against it, causing the third inclined block to move downwards. After the metal plate body completely passes the third inclined block, the third inclined block will return to its original position under the limiting action of the spring force and the third limiting rod. When the second inclined block subsequently bends the metal plate body, it will press against the metal plate body and push the first inclined block away from the second baffle. At this point, the third inclined block prevents it from moving away from the second baffle, thus making the device more stable during operation. Attached Figure Description

[0018] 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.

[0019] like Figures 1 to 7As shown, the present invention provides a bending device for a car seat adjuster handle, including a support base 1, a Z-shaped groove 16, a magnet block 17, and a through hole 9. A support frame 2 is fixedly connected to the top of the support base 1, and an electric hydraulic rod 3 is fixedly connected to the top of the support frame 2. A second limiting rod 13 is fixedly connected to the front and rear ends of the lower surface of the middle part of the support frame 2. A double-headed inclined block 4 is sleeved on the surface of the second limiting rod 13. A second baffle 6 and a first baffle 5 are fixedly connected to the front and rear ends of the top of the support base 1. A metal long plate body 14 is placed on the top of the support base 1. A first inclined block 7 and a second inclined block 11 are movably engaged in the inner cavities of the front and rear ends of the support base 1, respectively. A first limiting rod 10 is movably connected to the inner cavity of the second inclined block 11. A second tension spring 12 is sleeved on the outer surface of the first limiting rod 10. A first tension spring 8 is provided on the side of the first inclined block 7 away from the second limiting rod 13. The middle part is equipped with a blocking mechanism 15; by operating the electric hydraulic rod 3, the double-headed inclined block 4 will move downward, so that the double-headed inclined block 4 will first squeeze the first inclined block 7, and the side of the first inclined block 7 close to the metal long plate body 14 will squeeze the metal long plate body 14, so that the metal long plate body 14 will be bent into an L shape. As the electric hydraulic rod 3 continues to operate, the bottom of the double-headed inclined block 4, which is above the second inclined block 11, will squeeze the second inclined block 11. At this time, the second inclined block 11 will squeeze the bent end of the metal long plate body 14 under the limiting action of the first limiting rod 10 and the supporting base 1, so that the metal long plate body 14 will be bent into a Z shape. Finally, the bent metal long plate body 14 will fall through the Z-shaped groove 16, thus solving the problem that people need to adjust the metal long plate body 14 during bending, thereby improving bending efficiency.

[0020] like Figure 2 , Figure 5 , Figure 6 ,and Figure 7As shown, the blocking mechanism 15 includes a third inclined block 151, which is movably engaged in the inner cavity of the support base 1. Third limiting rods 152 are sleeved on both sides of the third inclined block 151, and springs 153 are sleeved on the outer surface of the third limiting rods 152. The side of the third inclined block 151 above the support base 1 is inclined, and the inclined surface of the third inclined block 151 is inclined towards the side closer to the first inclined block 7. The inclined surface of the third inclined block 151 cooperates with the metal long plate body 14. The top of the third limiting rod 152 is fixedly connected to the support base 1. The top and bottom of the spring 153 are fixedly connected to the third inclined block 151 and the third limiting rod 152, respectively. The mechanism works by bending the metal long plate body 14 for the first time... At the same time, the side of the metal plate body 14 that is close to the third inclined block 151 will squeeze the third inclined block 151, and the third inclined block 151 will move downward. After the metal plate body 14 completely passes the third inclined block 151, the third inclined block 151 will be reset under the elastic force of the spring 153 and the limiting action of the third limiting rod 152. When the second inclined block 11 bends the metal plate body 14, the second inclined block 11 will squeeze the metal plate body 14 and push the first inclined block 7 to move away from the second baffle 6. At this time, the third inclined block 151 plays a role in preventing it from moving away from the second baffle 6, thereby making the device more stable during operation.

[0021] like Figures 1 to 7 As shown, one end of the bottom of the electric hydraulic rod 3 passes through the support frame 2 and is fixedly connected to the top of the double-headed inclined block 4. The two ends of the bottom of the double-headed inclined block 4 are respectively located directly above the first inclined block 7 and the second inclined block 11. One end of the bottom of the second limiting rod 13 is located directly above the metal long plate body 14. The metal long plate body 14 is located between the second baffle 6 and the first baffle 5. The Z-shaped groove 16 is set on the top of the support base 1. The top of the first inclined block 7 is inclined on the side near the double-headed inclined block 4. The two ends of the first tension spring 8 are fixedly connected to the support base 1 and the first inclined block 7 respectively. Through the design of the first baffle 5 and the second baffle 6, the front and rear directions of the metal long plate body 14 are limited when it is bent for the first time, preventing the metal long plate body 14 from swaying back and forth during the turning process. The design of the first tension spring 8 facilitates the automatic reset of the first inclined block 7 after the electric hydraulic rod 3 drives the double-headed inclined block 4 to reset.

[0022] like Figures 1 to 7As shown, the middle of the top of the second inclined block 11 is inclined and is pressed against the rear end of the bottom of the double-headed inclined block 4. Both ends of the first limiting rod 10 are fixedly connected to the support base 1. Both ends of the second tension spring 12 are fixedly connected to the support base 1 and the second inclined block 11. The length of the end of the double-headed inclined block 4 directly above the first inclined block 7 is longer than the end of the double-headed inclined block 4 directly above the second inclined block 11. The upper and lower sides of the through hole 9 are respectively opened in the middle of the first inclined block 7 and inside the support base 1. The end of the double-headed inclined block 4 above the first inclined block 7 is movably connected to the inner cavity of the through hole 9. The magnet block 17 is located inside the support base 1, away from the second inclined block 11. One side of the baffle 6 is fixedly connected to the inner cavity of the support base 1, and the top of the magnet block 17 contacts the bottom of the metal long plate body 14 away from the second baffle 6. The design of the second tension spring 12 facilitates the automatic reset of the second inclined block 11 after the double-headed inclined block 4 is reset. At the same time, the design of the magnet block 17 plays a role in fixing the metal long plate body 14 at the beginning. By adsorbing the metal long plate body 14 with the magnet block 17, it is prevented that the end of the metal long plate body 14 near the second baffle 6 will tilt due to the lack of support for the metal long plate body 14 by the Z-shaped groove 16 below. It is worth noting that during the bending process of the metal plate body 14 by the device, the first inclined block 7 and the second inclined block 11 will both squeeze the metal plate body 14. At this time, even if the metal plate body 14 is released from the adsorption between it and the magnet block 17, the metal plate body 14 can still remain stable.

[0023] Working principle and usage process of this invention: First, the operator places one side of the metal long plate body 14 between the first baffle 5 and the second baffle 6. At the same time, the bottom of the metal long plate body 14 away from the second baffle 6 will be attracted by the magnet 17. Then, the operator operates the electric hydraulic rod 3, which will cause the double-headed inclined block 4 to move downward. This will cause the double-headed inclined block 4 to first squeeze the first inclined block 7, and the side of the first inclined block 7 close to the metal long plate body 14 will squeeze the metal long plate body 14, thus bending the metal long plate body 14 into an L shape. As the electric hydraulic rod 3 continues to operate, the bottom of the double-headed inclined block 4, which is above the second inclined block 11, will squeeze the second inclined block 11. At this time, the second inclined block 11 will squeeze the bent end of the metal long plate body 14 under the limiting action of the first limiting rod 10 and the support base 1, thus bending the metal long plate body 14 into a Z shape. Finally, the bent metal long plate body 14 will fall through the Z-shaped groove 16. While the metal plate body 14 is bending for the first time, the side of the metal plate body 14 closest to the third inclined block 151 will press against the third inclined block 151. At this time, the third inclined block 151 will move downward. After the metal plate body 14 has completely passed the third inclined block 151, the third inclined block 151 will be reset under the elastic force of the spring 153 and the limiting action of the third limiting rod 152. When the second inclined block 11 bends the metal plate body 14, the second inclined block 11 will press against the metal plate body 14 and push the first inclined block 7 to move away from the second baffle 6. At this time, the third inclined block 151 plays a role in preventing it from moving away from the second baffle 6, thereby making the device more stable during operation.
