Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of automobile seat, concretely relates to a reinforcing structure for upper supporting block of central armrest. BACKGROUND

[0002] The upper and lower ends of the central armrest of the second row seat are integrally formed with the seat back by foaming, the upper supporting block is used for reinforcing and fixing the headrest, and the lower supporting block is used for supporting the central armrest, since the upper supporting block is integrally formed with the seat back by foaming, the density of the PUR material used is the same, in order to meet the comfort of the seat back, the PUR material with low density needs to be used to meet the requirement of softness and elasticity of the seat back, and if the upper supporting block uses the PUR material with low density, the hardness is small, and the supporting property is not good, therefore the possibility of the upper supporting block to the sharp corner and other shapes is limited.

[0003] In order to meet the possibility of the upper supporting block to the sharp corner and other shapes, the prior art processes the upper supporting block, the seat back and the lower supporting block respectively, that is, the upper supporting block is made of EPP material, and the seat back and the lower supporting block are integrally formed by foaming of PUR material, although the possibility of the upper supporting block to the sharp corner and other shapes can be achieved, the following problems exist.

[0004] 1. The upper supporting block, the seat back and the lower supporting block need two sets of molds to be respectively made, wherein the upper supporting block is made of EPP mold, and the seat back and the lower supporting block are integrally formed by foaming of the foaming mold, therefore the manufacturing cost is high.

[0005] 2. When assembling, the seat back and the lower supporting block need to be installed on the seat frame, then the upper supporting block is clamped on the frame, and finally the skin is used to cover them, and the assembly time is high.

[0006] 3. When the skin is covered, the upper supporting block, the seat back and the lower supporting block are extruded, since the EPP material is harder than the PUR material, the indentation of the upper supporting block is much smaller than that of the seat back and the lower supporting block in the covering process, therefore the problems of deformation, collapse and height difference exist. INVENTION CONTENTS

[0007] The utility model aims at solving the above problems, and provides a reinforcing structure for the upper supporting block of the central armrest, which can meet the possibility of the upper supporting block to the sharp corner and other shapes, and has low manufacturing cost and assembly time, and does not have the problems of deformation, collapse and height difference.

[0008] In order to achieve the above object, the utility model provides a kind of reinforcing structure for central handrail upper support block, including upper support block and reinforcing block, the reinforcing block includes modeling area and connecting area, the modeling area is located in one side of upper support block, the connecting area is located in one side of seat back, the reinforcing block is foamed integrally formed with upper support block and seat back.

[0009] As further optimization, the reinforcing block adopts PUR material.

[0010] As further optimization, steel wire is additionally arranged in the seat back, the upper end of the steel wire is bent and extended to the upper support block in the direction of upper support block, and the lower end of the steel wire is bent and extended to the lower support block in the direction of lower support block.

[0011] Advantages and beneficial effects of the utility model

[0012] 1. The utility model adds reinforcing block of PUR material between upper support block and seat back, the modeling area of reinforcing block can meet the possibility of upper support block to sharp corner and other shapes, and the connecting area can prevent the connection between upper support block and seat back from tearing.

[0013] 2. The reinforcing block in the utility model is made of aluminum mold, and the seat back, the upper support block and the lower support block are foamed integrally formed by foaming mold, so the aluminum mold is lower in price than EPP mold, thereby reducing the manufacturing cost.

[0014] 3. The reinforcing block in the utility model is foamed integrally formed with the upper support block, the seat back and the lower support block after being shaped by aluminum mold, thereby reducing assembly time.

[0015] 4. The upper support block, the seat back and the lower support block in the utility model adopt PUR material with low density to meet the requirements of softness and elasticity of seat back, and the reinforcing block adopts PUR material with high density to meet the requirements of various shapes of upper support block, so the compression of the reinforcing block and the upper support block is the same as that of the seat back and the lower support block in the coating process, and therefore deformation, collapse and height difference do not occur.

[0016] 5. The utility model adds steel wire in the seat back, the upper end of the steel wire is bent and extended to the upper support block in the direction of upper support block, so that the upper support block is more stable and has stronger supporting capacity, and the lower end of the steel wire is bent and extended to the lower support block in the direction of lower support block, so that the lower support block is more stable and has stronger supporting capacity.

[0021] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0022] like Figure 1 and Figure 2 As shown, a reinforcing structure for a support block on a center armrest includes an upper support block 1 and a reinforcing block 2. The reinforcing block 2 is made of high-density PUR material, thus having greater hardness and better support, and can accommodate the possibility of sharp corners and other shapes on the upper support block. The reinforcing block 2 includes a shaping area 21 and a connecting area 22. The shaping area 21 is located on the front side of the upper support block 1, and the connecting area 22 is located on one side of the seat back 3. The reinforcing block 2 is shaped using an aluminum mold and then placed in a foaming mold to be integrally formed with the upper support block 1, the seat back 3, and the lower support block 4. Therefore, while solving the problem of sharp corners and other shapes on the upper support block 1, the requirements of elasticity and softness for the seat back 3 are met. At the same time, since both the reinforcing block 2 and the upper support block 1 are made of PUR material, the amount of indentation of the reinforcing block 2 and the upper support block 1 during the covering process is the same as the amount of indentation of the seat back 3 and the lower support block 4, so there will be no problems such as deformation, collapse, or height difference.

[0023] As further optimization, the seat back 3 is embedded with thickened steel wires on one side relative to the upper support block 1 and the lower support block 4, the upper end of the steel wire is bent to the upper support block 1 and extends into the upper support block 1, so that the upper support block 1 is more stable and has stronger supporting capacity, and the lower end of the steel wire is bent to the lower support block 4 and extends into the lower support block 4, so that the lower support block 4 is more stable and has stronger supporting capacity.
