Description

Comfort system installation structure and car seat Technical Field

[0001] The utility model relates to a car seat, and more particularly to a comfort system installation structure and the car seat. Background Art

[0002] With the rapid development of new energy vehicles, the demand for comfort quality is becoming increasingly higher, mainly reflected in the riding environment and sensory experience. Therefore, under ultra-quiet operating conditions, the requirements for seat comfort performance and sound quality in the car series launched by various OEMs in recent years have made a step-by-step leap, for example, requiring the noise level in the car to be less than 40 decibels. When comfort systems (such as ventilation and massage, etc.) are added to the rear seats, since the rear seats have metal and hard back panels, installing the comfort system on the back panel will cause noise and even vibration, which cannot meet the requirements. In addition, in the existing technology, the comfort system is also installed on the suspension springs of the second row seats or front seats. In this case, when the occupants sit in the second row seats or front seats, there will be a certain foreign body sensation because the suspension springs are relatively hard due to the rigidity and strength requirements and are not easy to deform. In addition, in the prior art, as shown in FIG3 , the air valve 21 of the comfort system 2 is installed on the back panel 1, and the air bag 23 is arranged on the front of the foam material 4 and the rear of the face cover 4a. In the process of connecting the air pipe 22 connected to the air valve 21 with the connector 23a of the air bag 23, the narrow operating space brings many inconveniences to the installation and wiring harness insertion of the air pipe 22, and may even cause problems such as air leakage. In particular, in this case, in order to ensure the connection between the air valve 21 and the air bag 23, since the valve 21 is installed on the back panel 1 and the air bag 23 is arranged on the front of the foam material 4, the valve 21 and the air bag 23 are far apart in the state shown in FIG3 , and a longer air pipe 22 is required for this purpose. This may cause the air pipe 22 to be bent when the back panel 1 and the foam material 4 are closed to complete the assembly, thereby causing the air path of the air pipe 22 to be blocked. Contents of the utility model

[0003] In order to solve the problems of noise and possible blocked tracheal air path in the above-mentioned prior art, the utility model provides a comfort system installation structure and a car seat.

[0004] The comfort system mounting structure of the present invention includes a comfort system, a support layer, and a foam material. The comfort system is mounted and fixed to the back of the foam material via the support layer. The support layer has a first connector, and the foam material has a second connector. The second connector is at least partially exposed from the foam material to allow for direct connection with the first connector or connection to the first connector via a fastener. The phrase "the comfort system is mounted and fixed to the back of the foam material via the support layer" does not mean that the entire comfort system is mounted and fixed to the back of the foam material via the support layer. Rather, it means that the comfort system is at least partially mounted and fixed to the back of the foam material via the support layer.

[0005] In some embodiments, the comfort system mounting structure further includes a back panel, the back side of the foam material is mounted on the back panel, and the comfort system is not directly connected to the back panel.

[0006] In some embodiments, the comfort system includes a foam pad or a tack cloth, and the comfort system is separated from the back panel by the foam pad or the tack cloth.

[0007] In some embodiments, there is a gap between the comfort system and the back panel near the foam block or tack cloth.

[0008] In some embodiments, the back panel is a seat sheet, a hard back panel, or a honeycomb panel.

[0009] In some embodiments, the supporting layer is a cloth mounting sheet or a felt board, and the first connecting member is configured as an extension formed along an edge of the mounting sheet or the felt board or formed outward from the supporting layer.

[0010] In some embodiments, the second connecting member is an embedded steel wire, and the extension portion passes around the steel wire and is fixedly connected to the steel wire.

[0011] In some embodiments, the support layer is a plastic or metal mounting plate, and the first connector cooperates with the fastener.

[0012] In some embodiments, the plastic or metal mounting plate has a weakening structure in the form of a strip-shaped hole or an edge recessed groove.

[0013] In some embodiments, the first connecting member is configured as a mounting hole.

[0014] In some embodiments, the second connecting member is an embedded plastic plate or a metal plate.

[0015] In some embodiments, the fastener is a snap, a C-ring, a cable tie, a rivet, or a screw.

[0016] In some embodiments, the comfort system includes an air valve, an air tube and an air bag, wherein the air valve is installed on the back of the support layer, the air tube runs from the back of the support layer to the front of the support layer, and the air bag connected to the air valve through the air tube is arranged at a position adjacent to the front of the foaming material.

[0017] In some embodiments, the comfort system further comprises an air pump, wherein the air pump is mounted on the back side of the support layer.

[0018] In some embodiments, the comfort system further comprises a fan, wherein the fan is mounted on the back side of the support layer.

[0019] According to the automobile seat of the present invention, it includes the above-mentioned comfort system installation structure.

[0020] According to the comfort system installation structure of the present invention, the comfort system is connected to the B side of the foam material, assembled into an integrated backrest assembly, and then installed on the backboard. This makes assembly simple and reliable, improving assembly efficiency. It can effectively eliminate the backboard vibration caused by the operating vibration of the comfort system (such as the control valve air pump, etc.) through the connection point when directly installed on the backboard. It can also reduce the seat amplitude, thereby improving the passenger discomfort caused by the matching factor between the body frequency and the seat frequency, and in principle reduce noise, sound absorption and vibration. In addition, unlike the prior art, the comfort system is first installed with the support layer to form a subassembly. In this case, there is no problem of limited operating space. The installation of the air pipe and the insertion of the wiring harness are unobstructed, which has significant assembly convenience. In other words, the comfort system is installed on the B side of the foam material through the support layer, assembled into an integrated backrest assembly, and then directly installed on the backboard. This makes assembly simple and reliable, improving assembly efficiency, and effectively avoiding the problems of low functional reliability and long assembly time caused by the need to connect various wiring harnesses and pipes of the comfort system in the narrow space formed by the backboard and the foam material when the comfort system is directly installed on the backboard in the prior art. Therefore, the comfort system installation structure according to the present invention is an integrated solution that integrates assembly convenience and effectiveness, noise, abnormal sound, and riding comfort.

[0042] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings and described in detail.

[0043] As shown in Figure 1, a comfort system installation structure according to a preferred first embodiment of the present invention includes a backboard 1, a comfort system 2, a support layer 3, and a foam material 4. The back side (i.e., side B) of the foam material 4 is mounted on the backboard 1, and the comfort system 2 is mounted and fixed to the back side of the foam material 4 via the support layer 3. This allows the foam material 4 to directly absorb noise generated by the comfort system 2, thereby isolating vibrations and reducing noise, eliminating abnormal noise. During the specific installation process, the comfort system 2 is first fixed to the support layer 3, and the two form a subassembly. The subassembly is then fixed, snapped together, or hooked to the foam material 4.

[0044] In this first embodiment, back panel 1 is the seat sheet metal, the comfort system includes massage components such as an air pump, and the comfort system 2 is not directly connected to the back panel 1, effectively physically isolating it. This effectively prevents the operating vibration of the comfort system 2 from causing sheet metal vibration and the noise that may be generated. As a result, the seat amplitude is reduced, thereby improving the passenger discomfort caused by the matching of the body frequency and the seat frequency. It should be understood that the specific structure of the back panel 1 mentioned here is only for example and not for limitation, and can be provided as a backrest frame or a seat cushion frame. It should be understood that the sheet metal mentioned here is only for example and not for limitation, and it is feasible to replace it with a hard back panel or honeycomb panel.

[0045] In this first embodiment, the comfort system 2 includes an air valve 21, an air tube 22, and an air bag 23. The air bag 23, connected to the air valve 21 via the air tube 22, is positioned adjacent to the front of the foam material 4, thereby providing a massage function for the passenger. Furthermore, the comfort system 2 includes a foam block or adhesive cloth 24, which is positioned on the back of the air valve 21. The foam block or adhesive cloth 24 separates the comfort system 2 from the back panel 1, further preventing vibrations in the operating comfort system 2 from causing sheet metal vibration and the resulting noise. It should be understood that the specific structure of the comfort system 2 described here is merely illustrative and not limiting. In practice, a gap exists between the comfort system 2 and the back panel 1 near the foam block or adhesive cloth 24. As the human body sinks into the foam material, the comfort system 2 moves backward following the foam material 4, effectively increasing human penetration and improving comfort and whiplash performance.

[0046] In this first embodiment, the support layer 3 is a fabric mounting sheet made of short-fiber cotton and provided with several first connectors 31 in the form of extensions, formed along the edges of the fabric mounting sheet or extending outward from the support layer 3. As shown in Figure 2, the comfort system 2 is mounted on the support layer 3. Specifically, the air valve 21 is mounted on the back of the support layer 3, the air tube 22 is routed from the back to the front and secured in place by a portion of the extensions (first connectors 31), and the air bag 23 is mounted on the front of the support layer 3. It should be understood that the material and shape of the support layer 3 mentioned here are merely illustrative and not limiting. For example, the fabric mounting sheet could be replaced with a felt board. As shown in Figure 3, in the prior art, the air valve 21 of the comfort system 2 is mounted on the back panel 1, and the air bag 23 is positioned on the front of the foam material 4 and behind the face cover 4a. During the connection between the air tube 22 connected to the air valve 21 and the connector 23a of the air bag 23, the narrow operating space causes significant inconvenience in installing the air tube 22 and inserting the wiring harness, and may even lead to problems such as air leakage. As shown in Figure 4, in the present invention, the comfort system 2 is first installed with the support layer 3 to form a subassembly. This eliminates the problem of limited operating space, and the installation of the air tube 22 and the insertion of the wiring harness are unobstructed, making assembly significantly easier. That is to say, the comfort system 2 is installed on the B side of the foam material 4 through the support layer 3, assembled into an integrated backrest assembly and then directly installed on the back panel 1. The assembly is simple and reliable, which improves the assembly efficiency and effectively avoids the problems in the prior art that the comfort system 2 is directly installed on the back panel 1, and it is necessary to connect various wiring harnesses and pipes of the comfort system 2 in the narrow space formed by the back panel 1 and the foam material 4, resulting in low functional reliability and long assembly time.

[0047] In this first embodiment, a second connector 41 in the form of a steel wire is embedded within the foam material 4. The extension portion of the support layer 3 (the first connector 31) is secured by passing through the steel wire (the second connector 41) of the foam material 4 to secure the support layer 3 to the foam material 4. The steel wire embedded within the foam material 4 strengthens the connection strength of the extension portion of the support layer 3 while ensuring that the foam material 4 is not damaged. It should be understood that the embedded second connector 41 is at least partially exposed from the foam material 4 to facilitate the installation and securement of the support layer 3. It should be understood that the extension portion (the first connector 31) can be secured by a snap fastener, Velcro, a bristle strip, or a cable tie, among other methods.

[0048] As shown in Figures 5 and 6 , the comfort system 2 of another preferred second embodiment of the comfort system mounting structure of the present invention further comprises an air pump 25 and a fan 26. The fan 26 provides ventilation, while the air pump 25 supplies air to the air valve. The support layer 3 is a mounting plate provided with a plurality of first connectors 31 in the form of mounting holes. The foam material 4 is embedded with plate-shaped connectors. Fasteners 5 (see Figure 8 ) are inserted into the mounting holes to secure the support layer 3 to the foam material 4. It should be understood that the mounting plate of the support layer 3 can be a felt board or a plastic board. Specifically, the plastic board of the support layer 3 includes a weakening structure 32 in the form of strip-shaped holes or edge recesses. This provides the required mounting strength while minimizing the sense of foreign body or presence (e.g., a weak backrest pressure). Due to the use of plastic, the plastic board is more susceptible to deformation compared to metal suspension springs in the prior art due to its inherent material properties. Furthermore, due to the weakening structure of the plastic board, it is also more susceptible to deformation from a structural perspective. This reduces the sense of foreign body or presence, thereby providing passengers with a higher riding comfort experience. It should be understood that the embedded plate of the foam material 4 can be a plastic plate or a metal plate. It should be understood that the fasteners here are detachable connectors, including clips, C-rings, cable ties, rivets or screws, etc. In addition, it should be noted that the air pump 25 and fan 26 of the comfort system in the second embodiment are installed on the basis of the comfort system of the first embodiment, that is, the comfort system of the second embodiment includes an air valve, an air pipe and an air bag as well as an air pump 25 and a fan 26. Here, the air valve can be provided with gas by an air pump, that is, the air pump can serve as an independent air source for the air valve. If a separate air pump is not provided, the air valve can obtain the required gas from other air sources in the vehicle, for example.

[0049] In fact, the material of the support layer 3 can be cloth, such as non-woven fabrics or felt textiles made of short fibers or filaments of synthetic fibers such as PP and PET and natural fibers such as cotton and linen through carding, needle punching, hot rolling and other processes; it can also be plastic, such as ABS, PCABC, PP+L / SGF, PVC, PP, PE, PC, PA66, PA6, PA66+GF, PA6+GF, etc.; it can also be metal.

[0050] In fact, the second connecting member 41 embedded in the foam material 4 can be a metal plate; it can also be a plastic plate, such as ABS, PCABC, PP+L / SGF, PVC, PP, PE, PC, PA66, PA6, PA66+GF, PA6+GF, etc.; it can also be a steel wire.

[0051] In the first example, the supporting layer 3 is short-fiber cotton, and the second connecting member 41 of the foam material 4 is an embedded steel wire (the depth of the embedded steel wire is ≥8 mm). The connection method is that the extension part of the short-fiber cotton (the first connecting member 31) is plus a male and female buckle that is buckled around the steel wire itself, as shown in Figure 7.

[0052] In the second example, the support layer 3 is short-fiber cotton, and the second connecting member 41 of the foam material 4 is an embedded steel wire. The connection method is that the extension of the short-fiber cotton (first connecting member 31) forms a self-supporting ear that passes through the steel wire and is fixed by the fastener 5, as shown in Figure 8. In this example, the fastener 5 is a buckle, as shown in Figure 9.

[0053] In the third example, the support layer 3 is short-fiber cotton, and the second connector 41 of the foam material 4 is an embedded steel wire. The connection method is that the extension of the short-fiber cotton (first connector 31) forms a self-supporting ear that passes over the steel wire and is secured by a C-shaped fastener 5, as shown in Figure 10. The C-shaped fastener 5 in Figure 10 is a fastener in a tightened state. In the initial state, the C-shaped ring is C-shaped. After passing through the extension (first connector 31) and surrounding the embedded steel wire (second connector 41) of the foam material 4, the C-shaped ring undergoes plastic deformation, thereby forming the ring structure shown in Figure 10. This ring structure may have overlapping portions, similar in form to a "keychain."

[0054] In the fourth example, the supporting layer 3 is short-fiber cotton, the second connecting member 41 of the foam material 4 is an embedded plastic sheet (the depth of the embedded steel wire is ≥5 mm), and the connection method is that the extension part of the short-fiber cotton (the first connecting member 31) is fixed to the embedded plastic sheet through a fastener 5 in the form of a pine card, as shown in Figure 11.

[0055] In the fifth example, the support layer 3 is a plastic plate, and the second connecting member 41 of the foam material 4 is an embedded metal sheet (matching the internal threaded opening). The connection method is that the mounting hole (first connecting member 31) of the plastic plate is fixed to the embedded metal sheet via a fastener 5, as shown in Figure 12. In this example, the fastener 5 is a screw, as shown in Figure 13.

[0056] In the sixth and seventh examples, the supporting layer 3 is a felt board, the second connecting member 41 of the foaming material 4 is a plastic member, and the connection method is snap connection, as shown in FIG. 14 and FIG. 15 .

[0057] Next, referring to Figures 16 and 17 , a comfort system mounting structure according to another preferred third embodiment of the present invention will be described. This comfort system mounting structure also includes a comfort system 2 comprising an air valve 21, an air pipe 22, and an air bag 23. The air bag 23, connected to the air valve 21 via the air pipe 22, is positioned adjacent to the front surface of the foam material 4, thereby providing a massage function for the passenger. The air valve 21 is mounted on the back surface of the support layer 3. The air pipe 22 is guided and secured by an air pipe guide 221 on the back surface of the support layer 3 and then passes from the back surface of the support layer 3 to the front surface of the support layer 3. This comfort system mounting structure also includes an air pump 25 and a fan 26. The fan 26 provides ventilation, while the air pump 25 serves as an independent air source to supply air to the air valve 21. The support layer 3 is a mounting plate having a plurality of first connectors 31 in the form of mounting holes. The foam material 4 is embedded with plate-shaped connectors. Fasteners 5 are inserted into the mounting holes to secure the support layer 3 to the foam material 4. It should be understood that the mounting plate of the support layer 3 can be a felt board or a plastic board. Specifically, the plastic board of the support layer 3 has a weakening structure 32 in the form of strip-shaped holes or edge recesses, which provides the required mounting strength while minimizing the sense of foreign body / presence (e.g., a weak sense of backrest pressure). Because plastic is used, the plastic board is more susceptible to deformation compared to metal suspension springs in the prior art due to its inherent material properties. Furthermore, due to the weakening structure of the plastic board, it is also more susceptible to deformation from a structural perspective, thereby reducing the sense of foreign body / presence, thereby providing passengers with a higher riding comfort experience. Unlike the second embodiment, the number of strip-shaped holes is reduced to facilitate the installation of other structures, such as the airway guide 221. It should be understood that the number, location, and direction of the strip-shaped holes can be arbitrarily selected as needed. The inner panel of the foam material 4 can be a plastic board or a metal board. It should be understood that the fasteners here are detachable connectors, including clips, C-rings, cable ties, rivets, or screws.

[0058] Next, the arrangement of the comfort system 2 of the comfort system mounting structure according to one embodiment will be described with reference to Figures 18 to 21. In the comfort system 2, the arrangement of the air pipe 22 and the air bag 23 is performed as in the prior art. As described above, the air bag 23 is positioned adjacent to the front surface of the foam material 4 (see Figure 19). As shown in Figures 18, 20, and 21, the air pipe 22 for connecting the air bag 23 to the air valve 21 passes through a through groove 222 provided near the side surface of the foam material 4, thereby connecting the air valve 21 provided on the support layer 3 on the back surface of the foam material 4 to the air bag 23 adjacent to the front surface of the foam material 4. The air valve 22 and air pump 23 of the comfort system 2 that may generate vibration are arranged on the back of the support layer 3 according to the utility model (see Figure 20). On the one hand, this can achieve vibration reduction, vibration isolation and noise reduction. On the other hand, since the comfort system 2 is first installed with the support layer 3 to form a subassembly and can thus be pre-installed on the foam material 4, the installation of the air pipe 22 and the insertion of the wiring harness are unobstructed, which has obvious assembly convenience. That is, the comfort system 2 is installed on the B side of the foam material 4 through the support layer 3, assembled into an integrated backrest assembly and then directly installed on the back panel 1. The assembly is simple and reliable, which improves the assembly efficiency.

[0059] In short, the comfort system mounting structure of the present invention can effectively reduce noise, absorb sound, and reduce vibration, thereby improving ride comfort and whiplash performance. In other words, the comfort system mounting structure of the present invention can achieve high requirements for noise and comfort while taking whiplash performance into consideration.

[0060] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. Various modifications are possible to the above embodiments of the present invention. In other words, any simple, equivalent changes and modifications made in accordance with the claims and description of the present invention fall within the scope of protection of the present invention. Anything not fully described in this invention represents conventional technology.
