[0029] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] Reference below Figure 1-Figure 2 A headrest mold 100 for a vehicle according to an embodiment of the present invention is described.

[0031] like Figure 1-Figure 2 As shown, the headrest mold 100 according to the present invention includes: a mold body 1, the mold body 1 defines a placement space for placing the headrest; a plurality of fixing members 2, the fixing members 2 are detachably arranged on the mold body 1, and the fixing members 2 are arranged at opposite ends of the placement space; a plurality of pull rings 3, the plurality of pull rings 3 correspond to the plurality of fixing members 2 one by one, the pull rings 3 are rotatably arranged on the corresponding fixing members 2, and the pull rings 3 are suitable for fixing a pull wire fixed at one end to the seam line of the headrest.

[0032] The mold body 1 defines a placement space, which can provide a placement position for the headrest to facilitate filling the headrest. There can be multiple fixing members 2, for example, there can be two, three or more fixing members 2. This application takes two fixing members 2 as an example for explanation. Along the width direction of the mold body 1, that is, Figure 1 In the X direction shown, two fixing members 2 can be respectively arranged at opposite ends of the placement space. The fixing member 2 is detachably arranged on the mold body 1, so that the fixing member 2 can be disassembled and replaced as needed, reducing the risk of poor quality of the processed headrest due to failure of the fixing member 2.

[0033] There can be multiple pull rings 3, and multiple pull rings 3 are arranged in one-to-one correspondence with multiple fixing members 2. For example, there can be two, three or more pull rings 3, and there can be two, three or more fixing members 2. This application takes two pull rings 3 and two fixing members 2 as an example for explanation. Further, the pull ring 3 can be rotatably arranged on the corresponding fixing member 2, so that the pull ring 3 can be rotated to a suitable position as needed (for example, according to the length of the pull wire). The pull ring 3 can be used to fix a pull wire fixed at one end to the seam line of the headrest, that is, one end of the pull wire (not shown in the figure) is fixed to the seam line of the headrest, and the other end of the pull wire is fixed to the pull ring 3, so that the pull ring 3 can limit the seam line of the headrest through the pull wire, which is conducive to the seam line of the headrest being maintained or approximately maintained in a straight state (the distortion meets certain requirements, for example: the distortion is less than or equal to 2mm) under the tension of the pull wire, which is conducive to improving the quality of the headrest, thereby improving the qualified rate of the production and processing of the headrest.

[0034] That is to say, two pull rings 3 are rotatably arranged on two fixing members 2, and the two pull rings 3 are suitable for fixing a pull wire whose one end is fixed to the seam line of the headrest. It can be understood that there are two pull wires, one end of each of which is fixed to the seam line of the headrest, and the other ends of each of the two pull wires are fixedly matched with the two pull rings 3, so that pull wires can be arranged on both sides of the seam line of the headrest, and by adjusting the position of the pull ring 3, the pull wires on both sides of the seam line of the headrest can be straightened to limit the seam line of the headrest.

[0035] Specifically, fixing parts 2 are provided on both sides of the mold body 1, and each fixing part 2 is provided with a corresponding pull ring 3. When the headrest needs to be filled, the headrest to be filled is placed in the placement space. Two pull wires are fixed on the headrest, one end of the two pull wires are respectively fixed on both sides of the seam line of the headrest, and the other ends of the two pull wires are respectively fixed on the corresponding pull rings 3. The pull ring 3 is controlled to rotate relative to the fixing part 2 so that the two pull wires tighten the seam line of the headrest on both sides of the seam line of the headrest, thereby reducing the risk of the headrest cover being impacted by the foaming material during the filling process, resulting in the seam being not straight and twisted. After the headrest is filled, the pull wire can be cut to remove the pull wire from the headrest to avoid the pull wire remaining on the headrest, affecting the exquisite appearance of the headrest, thereby improving customer satisfaction.

[0036] Furthermore, compared with the later manual shaping of the joints of the headrest cover, the method of the present application can greatly reduce the workload of operators, save time for manual shaping, and thus improve the production efficiency of the headrest.

[0037] Therefore, by providing the pull ring 3 and setting the pull ring 3 on the mold body 1 through the corresponding fixing part 2, the pull ring 3 can be fixed with one end of the pull wire fixed at the seam line of the headrest, which is beneficial for the seam line of the headrest to maintain or approximately maintain a straight line state (the distortion amount meets certain requirements, for example: the distortion amount is less than or equal to 2mm) under the tension of the pull wire, which is beneficial for improving the quality of the headrest, thereby improving the qualified rate of the headrest production and processing.

[0038] In some examples of the present invention, Figure 1 As shown, the headrest mold 100 may also include: multiple rotating pins 4, multiple pull rings 3, multiple rotating pins 4, and multiple fixing members 2 corresponding to each other, and the rotating pins 4 are assembled with the corresponding fixing members 2 and the corresponding pull rings 3 so that the pull rings 3 can be rotatably arranged on the corresponding fixing members 2.

[0039] Among them, multiple pull rings 3, multiple rotating pins 4, and multiple fixings 2 correspond one to one, that is, one rotating pin 4 corresponds to one pull ring 3 and one fixing 2, and the rotating pin 4 is assembled with the corresponding fixing 2 and the corresponding pull ring 3, so that the pull ring 3 can be rotatably arranged on the corresponding fixing 2. For example, the fixing 2 and the pull ring 3 are both formed with corresponding assembly holes. By inserting the rotating pin 4 into the assembly hole of the fixing 2 and the assembly hole of the pull ring 3, the effect of rotatably arranging the pull ring 3 on the corresponding fixing 2 can be achieved, so that the pull ring 3 can be rotated to a suitable position to tighten the pull wire, and then the pull ring 3 tightens the seam line of the headrest through the pull wire, which is beneficial to reduce the risk of crooked seams and twisting at the seams during the filling process of the headrest, thereby improving the quality of the headrest.

[0040] In some examples of the present invention, Figure 2As shown, the pull ring 3 may include: a rotating portion 31 and a pull ring body 32, the rotating portion 31 is connected to the pull ring body 32 and is assembled with the rotating pin 4, the pull ring body 32 has a mounting groove 321, and the mounting groove 321 is suitable for fixing a pull wire with one end fixed to the seam line of the headrest.

[0041] Among them, as some embodiments of the present application, the rotating part 31 and the pull ring body 32 can be integrally formed.

As some embodiments of the present application, the pull wire can include a wire body and a limiter, and the limiter is arranged at both ends of the wire body. The limiter at one end of the pull wire can be fixed at the seam line of the headrest, and the limiter at the other end of the pull wire can be assembled in the mounting groove 321, so that the mounting groove 321 can reliably fix the pull wire fixed at one end at the seam line of the headrest. By rotating the pull ring 3, the pull wire can be tightened to tighten the seam line of the headrest, reducing the risk of the seam of the headrest cover being not straight and twisted during the filling process, thereby improving the qualified rate of the headrest production and processing.

[0042] In some examples of the present invention, Figure 2 As shown, the mounting groove 321 may include: a first mounting groove 3211 and a second mounting groove 3212, the first mounting groove 3211 is formed at one end of the pull ring body 32 away from the rotating part 31 and is recessed toward the rotating part 31, the second mounting groove 3212 is formed at one end of the first mounting groove 3211 close to the rotating part 31 and is recessed along the thickness direction of the pull ring body 32, the first mounting groove 3211 is connected to the second mounting groove 3212, the first mounting groove 3211 is used to avoid the pull wire, and the inner wall of the second mounting groove 3212 is used to abut and cooperate with the pull wire.

Such a setting can make the setting of the first mounting groove 3211 and the second mounting groove 3212 reasonable, which is beneficial for the first mounting groove 3211 to avoid the pull wire (the pull wire is passed through the first mounting groove 3211), and realize the effect of the limit part of the pull wire abutting and matching with the inner wall of the second mounting groove 3212. By assembling the pull wire in the first installation groove 3211 and the limiting portion abutting against the inner wall of the second installation groove 3212, the risk of the pull wire falling off the pull ring body 32 can be reduced, thereby improving the limiting reliability of the seam of the headrest guard, and further reducing the risk of the seam of the headrest guard being crooked or twisted. The pull wire and the pull ring body 32 are easy to disassemble and assemble, which is conducive to improving the convenience of use of the headrest mold.
