Description

Technical Field

[0001] The utility model relates to the field of automobile interior decoration, in particular to a seat back plate. Background Art

[0002] The seat back of the car includes a back plate body and leather coated on the back plate body. The back plate body is coated with leather to improve the aesthetics of the seat back. For some seat back plates, during injection molding, a plurality of leather grain particles are also formed on the surface of the back plate body. The leather is coated on the back plate body. Due to the presence of the leather grain particles, the surface of the leather is uneven, thereby forming leather grains, which further improves the aesthetics of the product.

[0003] However, during the male mold covering process, after the leather is covered on the back panel body, there is poor air ventilation between the leather and the back panel body, especially in the concave part and the curved part of the back panel body. In this way, the gas is located between the leather and the back panel body, and bulging will appear on the leather. The tearing force between the leather and the back panel body is unsatisfactory, and the leather is easy to fall off the back panel body. Utility Model Content

[0004] The utility model aims to provide a seat back plate to solve the problem of poor air discharge between leather and a back plate body and to improve the tearing force between the leather and the back plate body.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: a seat back panel, including a back panel body, the back panel body is provided with an exhaust wire groove and a plurality of exhaust holes, and the exhaust wire groove connects the plurality of exhaust holes.

[0006] The principle and advantage of this solution are: by setting exhaust holes, when the leather is covered on the back plate body, the gas can be discharged from the exhaust holes, thereby reducing the gas between the leather and the back plate body and reducing the bulging phenomenon on the leather.

[0007] In order to avoid obvious depression at the vent holes after leather covering due to the setting of vent holes and to ensure the beauty of leather covering, the vent holes cannot be set too densely, or some parts on the back panel body cannot be formed with vent holes due to the limitation of injection molding process. In this case, when the vent holes cannot be set too densely or there are no vent holes in some parts, if the vent holes are simply set, there will be a phenomenon of air being trapped in the parts far away from the vent holes, so that the gas in the parts far away from the vent holes cannot be discharged normally, and the phenomenon of bulging still occurs. In this scheme, multiple vent holes are connected by using exhaust wire grooves, so that the gas in the parts where air may be trapped flows toward the exhaust holes through the exhaust wire grooves, so that it can be discharged from the nearest exhaust holes, making the exhaust area larger and the exhaust effect better, greatly reducing the bulging phenomenon, improving the tearing force of the leather covering, and greatly improving the product quality.

[0008] Preferably, as an improvement, the exhaust hole is a stepped hole.

[0009] The exhaust hole is set as a stepped hole. The stepped shape can increase the strength of the hole and avoid surface pits caused by deformation of the back plate body during the adsorption of leather. At the same time, the molding needle for forming the exhaust hole is also stepped, which has greater strength and improves the service life.

[0010] Preferably, as an improvement, the diameter of the small end of the stepped hole is 0.8-2 mm.

[0011] The aperture size of the small end of the step hole is related to the thickness of the leather. When the thickness of the leather is larger, the leather is less likely to sag at the exhaust hole. At this time, the aperture size of the small end of the step hole can be set larger. When the thickness of the leather is smaller, the leather is prone to sag at the exhaust hole. Therefore, in order to avoid more obvious sag of the leather, the aperture size of the small end of the step hole is set smaller.

[0012] Preferably, as an improvement, the width of the exhaust groove is smaller than the diameter of the exhaust hole.

[0013] Therefore, the width of the exhaust groove is smaller than the aperture of the exhaust hole, and the width of the exhaust groove will not be too large, thereby avoiding the abnormality of the single-skin positive mold covering caused by the excessive width of the exhaust groove and causing quality defects.

[0014] Preferably, as an improvement, the exhaust line duct includes a main line duct and a plurality of branch line ducts cross-connected to the main line duct.

[0015] Therefore, the setting of the branch trough can make the extension area of ​​the exhaust trough larger, thereby further increasing the exhaust area, making the exhaust effect better, greatly reducing the bulging phenomenon, improving the tearing force of the leather covering, and greatly improving the product quality.

[0016] Preferably, as an improvement, the distance between adjacent branch line ducts is 8-150 mm.

[0017] Therefore, the appropriate distance between branch ducts is 8-150mm. When it is smaller than this range, the branch ducts are arranged more densely, which will affect the leather covering effect. When it is larger than this range, the branch ducts are arranged more sparsely and the exhaust enhancement effect is not obvious.

[0018] Preferably, as an improvement, the branch line trough extends to both sides of the main line trough, and the branch line trough is located on both sides of the main line trough with a length of 8-150 mm each.

[0019] Preferably, as an improvement, the width and depth of the exhaust wire groove are both 0.2 mm. Therefore, it is more appropriate to set the width and depth of the exhaust wire groove to this value.

[0020] Preferably, as an improvement, the exhaust line groove is located at the inner concave part of the back plate body or the curved part of the back plate body surface; the exhaust hole is located at the inner concave part of the back plate body or the curved part of the back plate body surface. The back plate body is provided with a relatively long inner concave part, and the inner concave part or the curved part of the back plate body surface is prone to poor exhaust, so the exhaust line groove and the exhaust hole are arranged here, which can improve the exhaust effect of the inner concave part or the curved part of the back plate body surface.

[0021] Preferably, as an improvement, a plurality of leather grain particles are provided on the back plate body, and the exhaust holes and exhaust grooves are located at the gaps between adjacent leather grain particles. Thus, the exhaust holes and exhaust grooves are not located on the surface of the leather grain particles, thus avoiding the leather covering defects caused by the exhaust holes and exhaust grooves being located on the surface of the leather grain particles. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Figure 1 It is a front view schematic diagram of the back panel body.

[0023] Figure 2 for Figure 1 Enlarged view of C in the middle. DETAILED DESCRIPTION

[0024] The following is further described in detail through specific implementation methods:

[0025] The reference numerals in the drawings of the specification include: a back plate body 1, an inner recess 2, an exhaust hole 3, a main line duct 4, and a branch line duct 5.

[0026] The embodiment is basically as shown in the attached Figure 1-Figure 2 As shown: a seat back panel, including a back panel body 1 and leather, wherein the leather is coated on the surface of the back panel body 1 by a male mold coating process.

[0027] The back panel body 1 is provided with a plurality of leather grain particles (not shown in the figure, the so-called leather grain particles are some raised particles on the surface of the back panel body 1), and a longer inner recess 2 is provided on the back panel body 1. Compared with other parts of the back panel body 1, the inner recess 2 is sunken downward, which is prone to poor ventilation. The leather material is coated on the back panel body 1, and the inner recess 2 is prone to bulging. For this reason, the inventor also provided an exhaust groove and a plurality of exhaust holes 3 on the inner recess 2 of the back panel body 1. The exhaust holes 3 and the exhaust grooves in this embodiment are both located in the gaps between adjacent leather grain particles (that is, the exhaust holes 3 and the exhaust grooves are not located on the surface of the leather grain particles), and the exhaust grooves are provided along the inner recess 2, and the exhaust grooves connect the plurality of exhaust holes 3.

[0028] The exhaust hole 3 in this embodiment is a stepped hole. The diameter of the small end of the stepped hole is 0.8-2 mm, specifically 0.8 mm in this embodiment. The width of the exhaust groove is smaller than the diameter of the exhaust hole 3, specifically, the width and depth of the exhaust groove are both 0.2 mm. Figure 2 As shown, in this embodiment, the exhaust line duct includes a main line duct 4 and a plurality of branch line ducts 5 cross-connected to the main line duct 4. The main line duct 4 is arranged along the inner recess 2, and the main line duct 4 connects the plurality of exhaust holes 3 in sequence. The distance between adjacent branch line ducts 5 is 8-150mm, preferably 8-12mm, and specifically 10mm in this embodiment. Of course, in other embodiments, the distance between adjacent branch line ducts 5 needs to be selected according to actual conditions. The branch line duct 5 extends to both sides of the main line duct 4. The lengths of the branch line duct 5 on both sides of the main line duct 4 are 8-150mm, preferably 8-12mm. The lengths of the branch line duct 5 on both sides of the main line duct 4 can be equal or unequal. Of course, in other embodiments, the lengths of the branch line duct need to be selected according to actual conditions.

[0029] In this embodiment, since the exhaust groove and the exhaust hole 3 are located in the gap between adjacent dermatoglyphic particles instead of being located on the dermatoglyphic particles, the coating defects caused by being located on the dermatoglyphic particles are avoided.

[0030] In this embodiment, by setting exhaust holes 3 in the gaps between adjacent leather grain particles, when the leather is wrapped on the backboard body 1, gas can be discharged from the exhaust holes 3, thereby reducing the gas between the leather and the backboard body 1 and reducing the bulging phenomenon on the leather.

[0031] At the same time, the setting of the exhaust duct allows the gas to flow toward the exhaust hole 3 through the exhaust duct for the parts far away from the exhaust hole 3, so that it can be discharged from the nearest exhaust hole 3, making the exhaust area larger and the exhaust effect better. By comparing with the coated products before the improvement, the bulging phenomenon is greatly reduced, the tearing force of the leather coating is improved, and the product quality is greatly improved.

[0032] Of course, in other embodiments, in order to improve the adhesion effect between the leather and the back panel body 1 and improve the tearing force of the coating, the exhaust holes 3 and the exhaust grooves can also be arranged between the leather grain particles in other parts of the back panel body 1 (areas outside the inner recess 2, including but not limited to the arc-shaped bend parts on the surface of the back panel body 1).

[0033] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
