[0027] The following describes in detail embodiments of the present application. Examples of the embodiments 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 application and are not to be construed as limiting the present application.

[0028] Reference below Figure 1-Figure 4 Description: A shaping tool 10 for a vehicle seat according to an embodiment of the present application includes a base 11, a connecting tube column 12 and a support member 13. The base 11 extends in the height direction and has an accommodating cavity 1121 formed therein. A portion of the connecting tube column 12 is disposed in the accommodating cavity 1121, and another portion of the connecting tube column 12 extends in a direction away from the base 11. A ventilation channel 121 suitable for gas circulation is formed therein. The support member 13 is disposed at the free end of the connecting tube column 12 and has an air outlet 131 formed on its surface that is connected to the air outlet 121. The support member 13 can selectively abut against the seat cover and guide the gas to the surface of the cover through the air outlet 131.

[0029] At present, the seat cover products are not shaped at the corners after processing, resulting in appearance quality problems such as bulges and crooked seams at the corners and small-angle areas of the existing seat cover products. In addition, the existing seat cover products cannot be repaired for appearance problems such as bulges and crooked seams after assembly and foam injection, resulting in serious waste of man-hours and low product qualification rate.

[0030] like Figure 1 and Figure 2As shown, specifically, the shaping tooling 10 includes a base 11, a connecting tube column 12 and a support member 13. The base 11 can extend in the height direction, and the base 11 can be placed on the equipment and fixed to the equipment. A accommodating cavity 1121 can be formed inside the base 11. A part of the connecting tube column 12 can be arranged in the accommodating cavity 1121, and another part of the connecting tube column 12 can extend in a direction away from the base 11, specifically, another part of the connecting tube column 12 extends in a direction away from the base 11 in the height direction. A ventilation channel 121 can be formed inside the connecting tube column 12, and the ventilation channel 121 can be used for gas circulation. The support member 13 can be arranged at the free end of the connecting tube column 12, and an air outlet 131 can be formed on the surface of the support member 13. The air outlet 131 can be connected to the air outlet 121, so that the gas in the air outlet 121 can flow to the outside through the air outlet 131.

[0031] Furthermore, the support member 13 can abut against the seat guard, and the air outlet holes 131 on the support member 13 can be set corresponding to the seat guard. When the gas is guided to the surface of the guard through the air outlet holes 131, the surface of the seat guard is flattened and then the seat guard is pressed against the support member 13, thereby adjusting the flatness of the seat guard surface and solving the problem of bulging of the seat guard. In addition, by shaping different positions of the seat guard, the seams of the seat guard are kept straight, thereby improving the product qualification rate.

[0032] In short, the shaping tool 10 for vehicle seats in the embodiment of the present application is provided with a connecting tube column 12 and a support member 13 on the base 11. A ventilation channel 121 can be formed inside the connecting tube column 12, and the surface of the support member 13 can abut against the seat cover, and the surface of the support member 13 is also formed with an air outlet 131 connected to the ventilation channel 121. During actual operation, the air flow can be guided to the air outlet 131 through the ventilation channel 121 and blown to the surface of the cover, and then the shape of the cover is changed by pressing with external force, thereby realizing the shaping of the seat cover and improving the product qualification rate and the exquisite appearance.

[0033] like Figure 3 As shown, in some embodiments of the present application, the support member 13 can be constructed as a hollow structure, and a ventilation cavity 132 can be formed inside the support member 13, and the ventilation cavity 132 can be connected to the ventilation channel 121 and the air outlet 131. The gas in the ventilation channel 121 can flow to the air outlet 131 through the ventilation cavity 132, and then blow to the surface of the protective face from the air outlet 131. By constructing the support member 13 as a hollow structure, the overall weight of the support member 13 can be reduced, and the use of the ventilation cavity 132 can ensure that the internal gas can pass through the air outlet 131 evenly, thereby realizing the lightweight of the shaping tooling 10 and improving the reliability of the shaping tooling 10.

[0034] like Figure 1 As shown, in some embodiments of the present application, the shaping tool 10 may further include an air supply device 14, which may include an air supply member 141 and an air pipe 142. The air pipe 142 may be arranged in the ventilation channel 121, and one end of the air pipe 142 may be connected to the air supply member 141, and the other end of the air pipe 142 may be connected to the ventilation cavity 132. The air supply member 141 may transport the gas into the ventilation cavity 132 through the air pipe 142, and then guide it to the surface of the protective face through the air outlet 131. In some embodiments, the air supply member 141 may be constructed as an air pump, a compressor, etc., and the air supply device 14 may enhance the pressure of the gas to make the gas flow, thereby achieving the effect of blowing the gas toward the surface of the protective face.

[0035] like Figure 3 As shown, in some embodiments of the present application, the support member 13 can be constructed as a hollow sphere, and the surface of the air sphere has a certain curvature. Since the surface of the protective surface has a certain curvature, constructing the support member 13 as an air sphere can make the contact effect between the support member 13 and the surface of the protective surface better, and the surface of the spherical structure is smoother, which can effectively avoid the problem of wear of the protective surface on the support member 13.

[0036] In some embodiments of the present application, the diameter of the support member 13 is d1, satisfying the relationship: 40mm≤d1≤50mm, that is, the diameter of the support member 13 can be any value between 40mm and 50mm. For example, the diameter of the support member 13 can be but not limited to 40mm, 43mm, 45mm, 47mm, 50mm, etc. If the diameter of the support member 13 is too large, it will result in the inability to reshape the corners. If the diameter of the support member 13 is too small, it will result in the need to reshape the corners multiple times. Therefore, setting the diameter of the support member 13 within the above range can ensure that the support member 13 can effectively support the seat surface.

[0037] In some embodiments of the present application, the inner diameter of the air outlet 131 is d2, satisfying the relationship: 3.5mm≤d2≤4.5mm, that is, the inner diameter of the air outlet 131 is any value between 3.5mm and 4.5mm. For example, the diameter of the air outlet 131 can be but not limited to 3.5mm, 3.8mm, 4.0mm, 4.3mm, 4.5mm, etc. If the inner diameter of the air outlet 131 is too large, the flow rate of the air flow will be reduced. To this end, it is necessary to increase the output power of the air supply device 14 and increase energy consumption. If the inner diameter of the air outlet 131 is too small, the flow rate of the gas will be reduced. Therefore, setting the inner diameter of the air outlet 131 within the above range can ensure that the air flow can effectively pass through the air outlet 131 and blow toward the surface of the seat cover.

[0038] like Figure 1 and Figure 3As shown, in some embodiments of the present application, the air outlet 131 can be constructed as a plurality of air outlet holes 131, and the plurality of air outlet holes 131 can be arranged at intervals on the surface of the support member 13. By providing a plurality of air outlet holes 131, it can be ensured that the gas in the ventilation cavity 132 can be evenly blown to the surface of the seat guard through the plurality of air outlet holes 131, so that the seat guard can be unfolded and facilitate subsequent pressing, thereby realizing the shaping of the seat guard, improving the product qualification rate and the exquisite appearance.

[0039] In some embodiments of the present application, the number of air outlet holes 131 is q, satisfying the relationship: 9≤q≤12, that is, the number of air outlet holes 131 can be any number between 9 and 12. For example, the number of air outlet holes 131 can be but not limited to 9, 10, 12, etc. This arrangement can ensure that the airflow can effectively pass through the air outlet holes 131 and blow toward the surface of the seat cover.

[0040] like Figure 4 As shown, in some embodiments of the present application, the base 11 may include a base 111 and a reinforcement portion 112. The base 111 can be placed on the device and fixed to the device, and the base 111 can extend in the horizontal direction. The reinforcement portion 112 can be arranged on the base 111, and the reinforcement portion 112 can extend in the height direction away from the base 111. An accommodating cavity 1121 can be formed inside the reinforcement portion 112. The reinforcement portion 112 can be used to accommodate part of the connecting pipe column 12. The reinforcement portion 112 can improve the overall strength of the base 11. Since there is a cavity inside the base 11, the provision of the reinforcement portion 112 can ensure that the base 11 can effectively support the connecting pipe column 12. In some embodiments, the reinforcement portion 112 can be constructed as a hollow cylinder.

[0041] like Figure 4 As shown, in some embodiments of the present application, a through hole 1111 can be formed in the base 111, and the through hole 1111 can be used to accommodate the air supply member 141 and part of the air pipe 142, and the through hole 1111 can be connected to the accommodating cavity 1121 to ensure that the other part of the air pipe 142 can be accommodated in the accommodating cavity 1121. By providing the through hole 1111 in the base 111 for the installation of the air supply member 141 and part of the air pipe 142, the space occupied by the air supply device 14 can be reduced, thereby reducing the space occupied by the overall tooling, and realizing the miniaturization of the shaping tooling 10.
