Description

Technical Field

[0001] This utility model relates to the field of vehicle armrest structure technology, specifically to a seat armrest receiving groove and a car seat. Background Technology

[0002] To improve driving comfort, many vehicles now feature armrests in the rear seats, along with armrest storage slots on the backrests. When not in use, the armrests can be rotated into these slots to accommodate three passengers in the rear. When the armrests are needed, they can be rotated out of the slots and then rotated to a horizontal position, providing support and storage for rear passengers. For common split-type backrests with a 40%+40% or 40%+20%+40% layout, taking the 40%+40% split-type backrest as an example, the 60% portion is the first support seat and the 40% portion is the second support seat. Both the first and second support seats are made of PUR material and are cast. During casting, a groove is formed on the first support seat that is recessed into the first support seat. When the first and second support seats are installed on the sheet metal parts of the seat back, the side wall of the second support seat and the groove of the first support seat together form the armrest receiving groove.

[0003] Using the existing structural form, the first support and the second support can form an armrest receiving groove structure. However, when the first support and the second support are installed and fixed to the backrest sheet metal, a cover needs to be covered on the outside of the first support and the outside of the second support. Since the first support and the second support are both made of highly elastic PUR material, the corner positions of the first support and the second support are prone to collapse under stress when the cover is covered. This results in dimensional deviations at the corner connection positions of the first support and the second support when they form the armrest receiving groove. When the armrest is rotated and placed in the armrest receiving groove, a large gap is generated between the armrest and the first support and the second support, which does not meet the product design requirements. Utility Model Content

[0004] The present invention aims to provide a seat armrest receiving groove and a car seat to solve the problem that the existing armrest receiving groove has low structural strength and is prone to gaps during use.

[0005] To solve the above problems, the present invention adopts the following technical solution: a seat armrest receiving groove, including a first support seat and a second support seat, a first corner reinforcement part is fixedly connected to the corner position of the first support seat, the strength of the first corner reinforcement part is greater than that of the first support seat, and a second corner reinforcement part is fixedly connected to the corner position of the second support seat, the strength of the second corner reinforcement part is greater than that of the second support seat.

[0006] The principle and beneficial effects of this solution are as follows: In this application, a first corner reinforcement is fixedly connected at the corner position of the first support base, and a second corner reinforcement is fixedly connected at the corner position of the second support base. The first and second corner reinforcements respectively strengthen the corner positions of the first and second support bases, thereby improving the structural strength of the armrest base and reducing the possibility of collapse at the corner position of the armrest receiving groove when the cover is covered after molding. This prevents gaps from appearing after the armrest is placed in the armrest receiving groove, which would affect the appearance quality of the product.

[0007] Preferably, as an improvement, the first corner reinforcement includes a first reinforcement seat integrally cast with the first support seat, and the second corner reinforcement includes a second reinforcement seat integrally cast with the second support seat.

[0008] In this technology, both the first and second support seats are cast from PUR material. Therefore, during actual casting, the first and second corner reinforcements can be cast first, and then the first support seat can be cast on the basis of the first corner reinforcement. Similarly, the second corner reinforcement can be cast first, and then the second support seat can be cast on the second corner reinforcement. This two-stage casting method is very easy to implement in the existing mold technology field. It is only necessary to control the strength of the first corner reinforcement to be greater than that of the first support seat, and the strength of the second corner reinforcement to be greater than that of the second support seat during the actual casting process. Whether the first and second corner reinforcements are made of the same PUR material as the first and second support seats, or other materials, it can be easily implemented from the perspective of casting process. The process is simple and casting is convenient.

[0009] Preferably, as an improvement, the first reinforcing seat is provided with a first positioning hole, and the second reinforcing seat is provided with a second positioning hole.

[0010] In this solution, when casting the first reinforcing seat and the second reinforcing seat, the first positioning hole and the second positioning hole are formed simultaneously. Thus, when casting the first support seat or the second support seat, the first positioning hole can be used to position the first reinforcing seat (the first reinforcing seat can be positioned by the positioning rod on the mold cooperating with the first positioning hole in the prior art), and the second positioning hole can be used to position the second reinforcing seat. This effectively ensures the stability and accuracy of the first reinforcing seat and the first support seat when they are cast sequentially, as well as the stability and accuracy of the second reinforcing seat and the second support seat when they are cast sequentially.

[0011] Preferably, as an improvement, the first positioning hole penetrates through the first reinforcing seat, and a first rounded corner is provided between the first positioning hole and the side of the first reinforcing seat; the second positioning hole penetrates through the second reinforcing seat, and a first rounded corner is provided between the second positioning hole and the side of the second reinforcing seat.

[0012] In this design, the first positioning hole penetrates the first reinforcing seat, and the second positioning hole penetrates the second reinforcing seat. This allows the positioning rod in the prior art to stably position the first and second reinforcing seats. At the same time, the first and second rounded corners serve as guides, facilitating the insertion of the positioning rod into the first or second positioning hole. This enables quick and accurate positioning of the first and second reinforcing seats, effectively ensuring the casting accuracy of the first and second support seats and improving casting efficiency.

[0013] Preferably, as an improvement, a noise reduction groove is provided between the first reinforcing seat and the side facing the first reinforcing seat.

[0014] In this solution, a noise reduction groove is provided on the side of the first reinforcing seat and the second reinforcing seat that are in direct contact with each other. By setting the noise reduction groove on the first reinforcing seat and / or the second reinforcing seat, the contact area between the side of the first reinforcing seat and the second reinforcing seat is effectively reduced. When the first reinforcing seat and the second reinforcing seat have a slight relative displacement during use, the noise generated can be effectively reduced, and the comfort of using the armrest seat can be improved.

[0015] Preferably, as an improvement, the noise reduction groove is located at the middle position on the side of the first reinforcing seat facing the second reinforcing seat, and the depth of the noise reduction groove is greater than or equal to 2mm.

[0016] During use, the first reinforcing seat and the first supporting seat form a six-part backrest. The armrest mainly contacts and cooperates with the first reinforcing seat and the first supporting seat. Therefore, in this solution, the noise reduction groove is set on the side of the first reinforcing seat facing the second reinforcing seat to improve the noise reduction effect. The noise reduction groove is located in the middle of the side of the first reinforcing seat facing the second reinforcing seat, so as to avoid the noise reduction groove from communicating with the side wall of the first reinforcing seat and affecting the appearance quality of the first reinforcing seat. There will be no gaps after the first and second reinforcing seats are fitted together, and the appearance is good. In addition, in this solution, the depth of the noise reduction groove is set to be greater than or equal to 2mm, which effectively ensures the noise reduction effect of the noise reduction groove.

[0017] Preferably, as an improvement, the first support, the first reinforcing seat, the second support, and the second reinforcing seat are all PUR foam plastic seats, with the density of the first reinforcing seat being greater than that of the first support and the density of the second reinforcing seat being greater than that of the second support.

[0018] In this solution, the first support, the first reinforcing seat, the second support, and the second reinforcing seat are all PUR foam plastic seats, with the same material. The only difference is that the density of the first reinforcing seat is greater than that of the first support, and the density of the second reinforcing seat is greater than that of the second support. The molding conditions are similar (such as heating temperature, holding pressure, and time), which can complete the casting molding conveniently and efficiently.

[0019] Preferably, as an improvement, the density range of the first support and the second support is 50-55 kg / m³. 3 The density of the first and second reinforcing seats is greater than or equal to 80 kg / m³. 3 .

[0020] In this scheme, the density of the first and second support bases is set at 50-55 kg / m³. 3 Within the range, and the density of the first and second reinforcing seats is greater than or equal to 80 kg / m³. 3 The range of the first and second reinforcing seats can effectively ensure that the strength of the first and second reinforcing seats after casting is significantly greater than that of the first and second supporting seats, thereby utilizing the first and second reinforcing seats to play a structural strengthening role at the corresponding corner positions.

[0021] Preferably, as an improvement, the edge of the side of the first reinforcing seat facing the second reinforcing seat is provided with a recessed groove that is recessed into the first reinforcing seat.

[0022] In actual processing and assembly, after forming the first reinforcing seat and the first support seat, it is necessary to cover the outside of the first reinforcing seat and the first support seat with a face mask. In this solution, by providing a recessed groove on the edge of the side of the first reinforcing seat, the seam of the face mask is avoided by the recessed groove, so that the face mask can be covered more neatly and the appearance quality of the face mask is improved.

[0023] A car seat, including the aforementioned armrest receiving groove.

[0024] In this solution, a seat armrest receiving groove is provided on the car seat, which makes the armrest receiving groove structure stable and less prone to collapse and deformation due to handling during use, effectively ensuring the appearance quality of the armrest receiving groove.

[0030] The following detailed description illustrates the specific implementation method:

[0031] The reference numerals in the accompanying drawings include: first support 1, second support 2, first reinforcing seat 3, first positioning hole 301, clearance groove 302, noise reduction groove 303, second reinforcing seat 4, second positioning hole 401, and handrail receiving groove 5.

[0032] Example 1

[0033] This embodiment is as shown in the attached figure. Figure 1 and Figure 2 As shown: A seat armrest receiving groove includes a first support base 1 and a second support base 2. A first corner reinforcement is fixedly connected to the corner position of the first support base 1, and the strength of the first corner reinforcement is greater than that of the first support base 1. A second corner reinforcement is fixedly connected to the corner position of the second support base 2, and the strength of the second corner reinforcement is greater than that of the second support base 2. In this embodiment, combined with... Figure 3 The first corner reinforcement includes a first reinforcing seat 3 integrally cast with the first support seat 1, and the second corner reinforcement includes a second reinforcing seat 4 integrally cast with the second support seat 2. All three supports—first support seat 1, first reinforcing seat 3, second support seat 2, and second reinforcing seat 4—are PUR foam plastic seats, meaning they are all cast from PUR material. The density of the first reinforcing seat 3 is greater than that of the first support seat 1, and the density of the second reinforcing seat 4 is greater than that of the second support seat 2. During actual casting, the density of the first support seat 1 and the second support seat 2 ranges from 50 to 55 kg / m³, preferably 50 kg / m³; the density of the first reinforcing seat 3 and the second reinforcing seat 4 is greater than or equal to 80 kg / m³, preferably 100 kg / m³, ensuring that the strengths of the first reinforcing seat 3 and the second reinforcing seat 4 are the same, and the strengths of the first support seat 1 and the second support seat 2 are the same. Furthermore, the strengths of both the first support seat 1 and the second support seat 2 are less than the strengths of the first reinforcing seat 3 and the second reinforcing seat 4.

[0034] In this embodiment, for the casting molding method of the first reinforcing seat 3 and the first supporting seat 1, the first reinforcing seat 3 can be cast first using a casting mold, and then a casting mold can be set up to install the formed first reinforcing seat 3 into the subsequently set casting mold (the first reinforcing seat 3 can be regarded as part of the subsequent casting mold). Then the first supporting seat 1 is cast. After casting, the first reinforcing seat 3 and the first supporting seat 1 are connected as one and fixed to each other. Similarly, the second reinforcing seat 4 and the second supporting seat 2 are cast using a similar casting molding method, which will not be described in detail here. The casting molding process of casting the first reinforcing seat 3 and the first supporting seat 1 sequentially using a mold is a conventional injection molding process, and its mold structure and molding principle will not be described in detail here. In addition, in order to ensure the stable and accurate position of the first reinforcing seat 3 when casting the first supporting seat 1, such as Figure 3 As shown, in this embodiment, a first positioning hole 301 is formed through the first reinforcing seat 3 during the casting process. A positioning rod that cooperates with the first positioning hole 301 can be set in the casting mold. The positioning rod plays a role in positioning and stabilizing the first reinforcing seat 3 during the casting process of the first support seat 1, which effectively ensures the casting quality of the first support seat 1. Similarly, a second positioning hole 401 is formed on the second reinforcing seat 4, which will not be described in detail here.

[0035] Combination Figure 3 and Figure 4 The first support base 1 has a groove formed by casting. The groove, together with the first support base 1, the first reinforcing base 3, the second support base 2, the second reinforcing base 4, and other components in the prior art (such as the seat back frame), forms an armrest receiving groove 5 for placing the armrest. At the same time, in the prior art, after the armrest receiving groove 5 is formed, a mask needs to be covered on the first reinforcing base 3 and the first support base 1. In order to improve the appearance quality of the covering, in this embodiment, a recessed groove 302 is provided on the edge of the side of the first reinforcing base 3 facing the second reinforcing base 4. The recessed groove 302 avoids the seam of the mask, so that the mask can cover more smoothly.

[0036] A car seat includes the aforementioned armrest receiving groove. By setting a first reinforcing seat 3 at the corner position of the first support seat 1 and a second reinforcing seat 4 at the corner position of the second support seat 2, the structural strength of the corner positions on the first support seat 1 and the second support seat 2 is improved, reducing the risk of the corner positions collapsing and deforming due to pressure when covered by the mask, and effectively ensuring the structural integrity of the armrest seat.

[0037] Example 2

[0038] The difference between Example 2 and Example 1 is as follows: Figure 5As shown, in this embodiment, a noise reduction groove 303 is provided between the opposite sides of the first reinforcing seat 3 and the second reinforcing seat 4. The noise reduction groove 303 can be provided on the first reinforcing seat 3 and / or the second reinforcing seat 4. In this embodiment, the noise reduction groove 303 is provided at the middle position of the side of the first reinforcing seat 3 facing the second reinforcing seat 4, and the depth of the noise reduction groove 303 is greater than or equal to 2mm, preferably 3mm. By providing the noise reduction groove 303, the contact area between the first reinforcing seat 3 and the second reinforcing seat 4 is reduced, effectively reducing the noise generated by the relative friction between the first reinforcing seat 3 and the second reinforcing seat 4 during use.
