Description

[0002] In recent years, cars have become one of the most important means of transportation for people's daily travel, and seat comfort has always been a key indicator of consumer concern. Car seats usually use high-hardness foam materials as the main filling material, which can easily lead to fatigue after sitting for a long time. In order to improve this situation, manufacturers usually offer optional accessories such as headrests or lumbar supports that can be installed in the seat headrests or lumbar supports, for consumers who need them.

[0003] As consumers' demands for automotive comfort continue to rise, headrest products have evolved from simple filling materials into complex systems integrating multiple functions such as heating and massage. The realization of these functions depends on the internal circuitry and air passages of the headrest. Different configurations of headrests require different numbers of circuit interfaces and air passage interfaces depending on the combination of functions. Therefore, currently, special connectors need to be designed and manufactured for different styles of headrests, which increases R&D, production and after-sales costs and affects the product iteration speed.

[0020] It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0021] As mentioned in the background section, in order to solve the problems existing in the prior art, this embodiment provides a modular pneumatic and electrical connection device for car seat hanging pillows. The car seat hanging pillow is set on the side of the car seat close to the human body. Specifically, it can be set in the headrest 7, backrest 6, seat cushion or leg rest of the car seat, etc., and can be detachably connected to the car seat by Velcro, fastening components or magnetic attraction. The connection device includes a detachably connected first connection mechanism 100 and a second connection mechanism 200. The first connecting mechanism 100 includes a first body 3, on which a first module 1 is detachably connected. The first module 1 includes at least one first air path module 11 and / or at least one first circuit module 12. The first air path module 11 is provided with a first air path connection structure, and the first circuit module 12 is provided with a first electrical connection structure. The first electrical connection structure is used to connect to a power supply device, and the first air path connection structure is used to connect to an air source device. The second connection mechanism 200 includes a second main body 4, on which a second module 2 is detachably connected. The second module 2 includes at least one second air path module 21 and / or at least one second circuit module 22. The second air path module 21 is provided with a second air path connection structure corresponding to the first air path connection structure, and the second circuit module 22 is provided with a second electrical connection structure corresponding to the first electrical connection structure. The second electrical connection structure is used to connect an electrical load, and the second air path connection structure is used to connect an air-using component. When the first connecting mechanism 100 and the second connecting mechanism 200 are plugged and fixed, the first electrical connection structure is plugged into the second electrical connection structure, and / or the first air connection structure is plugged into the second air connection structure, thereby making the power supply device electrically connected to the electrical load, and / or the air source device connected to the air-using component.

[0022] like Figure 11-14 As shown, the first connecting mechanism 100 can be arranged on the car seat, such as the bottom of the headrest 7, the top of the seat back 6, the back of the seat back 6, the seat cushion, the seat leg rest, the back panel or the side panel, or any other position where it can be installed. It can also be arranged on the car interior, such as the rear of the armrest box. The first connecting mechanism 100 is used to connect the independent power supply and / or air supply of the car seat, or the power supply and / or air supply of the whole vehicle. The second connecting mechanism 200 is arranged on the seat soft pillow 8 and can move within a certain range relative to the seat soft pillow 8 to connect with the first connecting mechanism 100. The second connecting mechanism 200 is used to connect the electrical load and / or air supply components of the seat soft pillow 8. The electrical load may be a heating pad, ventilation fan, adjustment device, mechanical massage device or audio system installed in the pillow, and the air supply components may be a massage airbag or support airbag installed in the pillow.

[0023] like Figure 1-4As shown, the first module 1 can be installed on the first body 3 by means of snap-fit, bolt connection or adhesive bonding. The structure of the first module 1 is selected from at least one of the first air circuit module 11, the first circuit module 12 and the combination of the two. The specific number and position of the air circuit module and the circuit module in the first module 1 can be freely adjusted according to the number of air components and electrical loads in the seat soft pillow 8. The second module 2 can be installed on the second body 4 by means of snap-fit, bolt connection or adhesive bonding. The specific number and position of the air circuit module and the circuit module in the second module 2 correspond to the first module 1.

[0024] like Figure 5-10 As shown, the first gas path connection structure and the first electrical connection structure can be integrally formed with the first gas path module 11 and the first circuit module 12 by injection molding, respectively. Alternatively, they can be manufactured separately and then fixed to the first gas path module 11 and the first electrical connection structure to the first circuit module 12. Similarly, the second gas path connection structure and the second electrical connection structure can be integrally formed or manufactured separately and then connected to the second gas path module 21 and the second circuit module 22, respectively. In this embodiment, the first gas path connection structure and the second gas path connection structure are both integrally formed on the first gas path module 11 and the second gas path module 12, respectively, and the first electrical connection structure and the second electrical connection structure are both inserted and fixed on the first circuit module 12 and the second circuit module 22, respectively.

[0025] like Figure 12-14As shown, in this embodiment, the seat-attached pillow 8 is a soft headrest located on the side of the seat headrest 7 closest to the human body. The seat headrest 7 is inserted into the seat backrest 6, and a receiving groove is provided at the top of the seat backrest 6. The first connecting mechanism 100 is fixed in the receiving groove. The first electrical connection structure and the first air connection structure in the first connecting mechanism 100 are respectively connected to a power supply device and an air supply device located inside the seat backrest 6. The seat headrest 7 is inserted into the seat backrest 6, and the soft seat-attached pillow 8 is provided on the side of the seat headrest 7 closest to the human body. The second connecting mechanism 200 is provided on the soft seat-attached pillow 8 and can move within a certain range relative to the soft seat-attached pillow 8. When the soft seat-attached pillow 8 is inserted into the seat backrest 6 together with the seat headrest 7, the second connecting mechanism 200 can connect with the first connecting mechanism at the top of the seat backrest 6. The first connecting mechanism 100 is inserted and fixed, thereby connecting the electrical load and pneumatic components inside the seat cushion 8 to the power supply device and the pneumatic source device, respectively. In other embodiments, the first connecting mechanism 100 can also be located on the seat headrest 7, for example, below the seat headrest 7. In this case, the first electrical connection structure and the first pneumatic connection structure can pass through the headrest rod and connect to the power supply device and the pneumatic source device located inside the seat back 6. Alternatively, the power supply device and the pneumatic source device can be located inside the seat headrest 7. No special limitation is made here. Through the above settings, the pneumatic and electrical circuits between the seat cushion 8 and the seat back 6 can be quickly inserted and connected. At the same time, when both the first connecting mechanism 100 and the second connecting mechanism 200 are pneumatic-electric integrated insertion structures, the pneumatic structure and the electrical structure can be connected synchronously, simplifying the connection steps and improving the connection efficiency.

[0026] By setting up freely combinable air circuit modules and circuit modules, corresponding first module 1 and second module 2 are formed according to the air circuit and circuit structure inside the seat soft pillow 8, so as to adapt to the connection requirements of seat pillows 8 with different structures. There is no need to redesign the plug, thus making the connection device modular and having wide applicability. At the same time, the detachable connection structure allows the corresponding electrical connection structure and air circuit connection structure on the two modules to be plugged in separately, realizing the quick connection of the air circuit structure and the circuit structure.

[0027] In a preferred embodiment, The first main body 3 is provided with a plurality of first slots 31, which are used to be plugged into and cooperate with the first air circuit module 11 or the first circuit module 12. The second main body 4 has multiple second slots 41, which are used to connect and cooperate with the second air circuit module 21 or the second circuit module 22.

[0028] like Figure 1 and Figure 5As shown, the first slot 31 is approximately a cuboid recess, and the inner contour of the first slot 31 can match the outer contour of the main body of the first air circuit module 11 and the first circuit module 12. Therefore, during use, the number and position of the first air circuit module 11 and the first circuit module 12 inserted into the first main body 3 can be freely adjusted according to the actual situation. Similarly, the second slot 41 is also approximately a cuboid recess, and the inner contour of the second slot 41 can match the outer contour of the main body of the second air circuit module 21 and the second circuit module 22. Therefore, during use, the number and position of the second air circuit module 21 and the second circuit module 22 inserted into the second main body 4 can be freely adjusted according to the actual situation. Through the above settings, the integrated pneumatic and electrical connection device can dynamically adapt to changes in demand, improve functional diversity, and reduce resource waste by making partial structural changes when demand changes, thus solving the problems of insufficient compatibility and expandability.

[0029] In a preferred embodiment, the first slot 31 and the second slot 41 are provided with a first snap-fit ​​structure, and the first air circuit module 11, the first circuit module 12, the second air circuit module 21 and the second circuit module 22 are each provided with a second snap-fit ​​structure corresponding to the first snap-fit ​​structure.

[0030] like Figure 1 and Figure 5 As shown, the first snap-fit ​​structure can be a snap-fit ​​block 311 or a snap-fit ​​groove 131, and the second snap-fit ​​structure can be a snap-fit ​​groove 131 or a snap-fit ​​block 311 corresponding to the first snap-fit ​​structure. In this embodiment, both the first slot 31 and the second slot 41 are provided with snap-fit ​​blocks 311, and the first air circuit module 11, the first circuit module 12, the second air circuit module 21 and the second circuit module 22 are all provided with snap-fit ​​grooves 131 corresponding to the snap-fit ​​blocks 311. After the first air circuit module 11 and the first circuit module 12 are inserted into the first slot 31, they can be snapped together with the snap-fit ​​blocks 311 and the snap-fit ​​grooves 131 to fix them to the first body 3. After the second air circuit module 21 and the second circuit module 22 are inserted into the second slot 41, they can be snapped together with the snap-fit ​​blocks 311 and the snap-fit ​​grooves 131 to fix them to the second body 4.

[0031] In a preferred embodiment, The first air passage connection structure 11 includes a first pneumatic plug 111 and a first air nozzle 112. A first air passage 113 is connected between the first pneumatic plug 111 and the first air nozzle 112. The first air nozzle 112 is connected to an air source device through a first air pipe. The second air passage connection structure 21 includes a second pneumatic plug 211 and a second air nozzle 212. A second air passage 213 is connected between the second pneumatic plug 211 and the second air nozzle 212. The second air nozzle 212 is connected to the air-using assembly through a second air pipe. The first pneumatic plug 111 is plugged into the second pneumatic plug 211 to connect the air source device to the air-using component.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, the first pneumatic plug 111 and the first air nozzle 112 are integrally formed at both ends of the first air circuit module 11. The first air circuit 113 passes through the first air circuit module 11 and connects to the first pneumatic plug 111 and the first air nozzle 112 respectively. The first air nozzle 112 is connected to the air source device through the first air tube. The second pneumatic plug 211 and the second air nozzle 212 are integrally formed at both ends of the second air circuit module 21. The second air circuit 213 passes through the second air circuit module 21 and connects to the second pneumatic plug 211 and the second air nozzle 212 respectively. The second air nozzle 212 is connected to the air source device through the second air tube. In this embodiment... In the example, the extension direction of the second pneumatic plug 211 is perpendicular to the extension direction of the second air nozzle 212. In other embodiments of this application, the extension direction of the second pneumatic plug 211 and the extension direction of the second air nozzle 212 can have any angle, as long as the second air nozzle 212 can be conveniently and quickly connected to the air-using component through the second air pipe. No special limitation is made here. When the first connecting mechanism 100 is inserted into the second connecting mechanism 200, the first pneumatic plug 111 can be inserted into the second pneumatic plug 211, and then the air source device is connected to the air-using component through the first air pipe and the second air pipe.

[0033] In a preferred embodiment, a sealing structure is also provided to achieve a sealed connection between the first pneumatic plug 111 and the second pneumatic plug 211.

[0034] like Figure 1 and Figure 2As shown, in this embodiment, the first pneumatic plug 111 has a concave structure, and the second pneumatic plug 211 has an outward convex structure. During connection, the second pneumatic plug 211 is inserted into the first pneumatic plug 111. The first pneumatic plug 111 also has a sealing structure inside. After the second pneumatic plug 211 is inserted, it can be fitted around the outer circumference of the second pneumatic plug 211 to seal the gap between the first pneumatic plug 111 and the second pneumatic plug 211 to achieve a seal. The sealing structure includes a first sealing ring 114 and a second sealing ring 115, both of which are annular structures. The first sealing ring 114 and the second sealing ring 115 are oriented towards... The first sealing ring 114 is arranged sequentially near the first air nozzle 112. The outer periphery of the first sealing ring 114 has a protrusion that can cooperate with the inner wall of the first pneumatic plug 111 to fix it, thereby limiting the second sealing ring 115 and preventing the second sealing ring 115 from coming out of the first pneumatic plug 111 during the insertion and removal of the second pneumatic plug 211. Furthermore, the first sealing ring 114 and the second sealing ring 115 can be made of soft materials such as silicone or rubber, or the second sealing ring 115 can be made of soft material while the first sealing ring 114 can be made of metal or plastic, which facilitates the limiting and fixing of the second sealing ring 115.

[0035] In a preferred embodiment, The first electrical connection structure 12 includes a first electric plug 121, a first wire harness 122 connected to the first electric plug 121, and a power supply device connected through the first wire harness 122. The second electrical connection structure 22 includes a second electric plug 221, on which a second wire harness 222 is connected, and through the second wire harness 222, an electrical load is connected. The first electric plug 121 and the second electric plug 221 are plugged in to connect the power supply device to the electrical load.

[0036] like Figure 1 , Figure 3 and Figure 4As shown, the first electric plug 121 and the second electric plug 221 include, but are not limited to, TYPE-C interfaces, TYPE-B interfaces, TYPE-A interfaces, terminals, metal springs, metal probes, and any other conductive structures unaffected by the number of insertions and removals. The first electric plug 121 is equipped with a first wiring harness 122, and the first electric plug 121 is connected to the power supply device through the first wiring harness 122. The first electric plug 121 can be inserted from one end of the first circuit module 12 to the other end port of the first circuit module 12 and fixed. The second electric plug 221 is equipped with a second wiring harness 222, and the second electric plug 221 is connected to the electrical load through the second wiring harness 222. The second electric plug 221 can be inserted from one end of the second circuit module 22 to the other end port of the second circuit module 22 and fixed. When the first connecting mechanism 100 is plugged into the second connecting mechanism 200, the first electric plug 121 and the second electric plug 221 can be plugged into each other, and the power supply device is electrically connected to the electrical load through the first wiring harness 122 and the second wiring harness 222.

[0037] In a preferred embodiment, the connection between the first electric plug 121 and the first wiring harness 122 is covered with a first seal 123, and the connection between the second electric plug 221 and the second wiring harness 222 is covered with a second seal 223.

[0038] like Figure 1 and Figure 3 As shown, the first seal 123 and the second seal 223 are both made of materials such as rubber and sealant. The first seal 123 is used to wrap the connection point after the first electric plug 121 and the first wiring harness 122 are assembled to prevent water ingress and short circuit. The second seal 223 is used to wrap the connection point after the second electric plug 221 and the second wiring harness 222 are assembled to prevent water ingress and short circuit.

[0039] In a preferred embodiment, the first module 1 is provided with a first plug-in structure, and the second body 4 is provided with a second plug-in structure corresponding to the first plug-in structure. When the first connecting mechanism 100 and the second connecting mechanism 200 are plugged in, the first plug-in structure and the second plug-in structure are engaged.

[0040] like Figure 5 , Figure 7 and Figure 9As shown, the first insertion structure is a snap-fit ​​protrusion 132 or a snap-fit ​​hole 412, and the second insertion structure is a snap-fit ​​hole 412 or a snap-fit ​​protrusion 132 corresponding to the first insertion structure. In this embodiment, snap-fit ​​protrusions 132 are provided on the first air circuit module 11 and the first circuit module 12. A snap-fit ​​hole 412 is provided on the side wall of the second slot 41 of the second body 4 corresponding to the snap-fit ​​protrusion 132. The distance between the end of the snap-fit ​​protrusion 132 near the second body 4 and the highest point of the protrusion on the first module 1 is greater than the distance between the end of the snap-fit ​​protrusion 132 near the first body 3 and the highest point of the protrusion on the first module 1. That is, the angle of the snap-fit ​​protrusion 132 near the second module 4 is smaller than the angle of the end of the snap-fit ​​protrusion 132 near the first module 3. Therefore, the force required to insert the first module 1 into the second body 4 is less than the force required to pull the first module 1 out of the second body 4.

[0041] In a preferred embodiment, the first body 3 also has a first connecting portion 32, which is used to fix to the car seat.

[0042] like Figure 6 As shown, the first main body 3 also has a first connecting part 32, which is approximately a flat plate structure. The first connecting part 32 has multiple connecting holes for fixing the first main body 3 to the car seat. The second main body 2 also has a second connecting part 42, which is approximately a flat plate structure for connecting the second main body 4 to the seat soft pillow 8.

[0043] In a preferred embodiment, a third body 5 is further included, which is fixed to the second body 4.

[0044] like Figure 5 As shown, the third body 5 is also similar to a flat plate structure. The third body 5 can be inserted into the second connecting part 42 of the second body 4 and fixed to the second body 4 by hot riveting. The third body 5 and the second connecting part 42 can cooperate with each other to clamp onto structures such as the seat soft pillow 8, seat headrest 7, seat detachable lumbar support, and seat detachable soft leg rest. Furthermore, the second body 4 may not be provided with the third body 5. The second body 4 can be connected to the seat soft pillow 8 through the second connecting part 42.
