Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to an integrated pneumatic and electrical connection device for automotive seat headrests. Background Technology

[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 to complex products integrating multiple functions such as heating and massage. The realization of these functions depends on the internal circuitry and air circuitry of the headrest. However, in current headrests, the circuitry and air circuitry are usually designed with separate connection interfaces. Users need to align the two interfaces and insert them into the corresponding positions in the vehicle. The operation process is cumbersome and prone to errors, which significantly reduces the user experience. Utility Model Content

[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 car seat attached pillow pneumatic-electric integrated connection device. The seat attached pillow 6 is set on the side of the car seat close to the human body. Specifically, it can be set in the headrest 5, backrest 4, seat cushion or leg rest, 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 1 and a second connection mechanism 2. The first connection mechanism 1 includes a first body, on which at least one first electrical connection structure 12 and at least one first air connection structure 11 are provided. The first electrical connection structure 12 is used to connect to a power supply device, and the first air connection structure 11 is used to connect to an air source device. The second connection mechanism 2 includes a second main body, on which a second electrical connection structure 22 corresponding to the first electrical connection structure 12 and a second air passage connection structure 21 corresponding to the first air passage connection structure 11 are provided. The second electrical connection structure 22 is used to connect an electrical load, and the second air passage connection structure 21 is used to connect an air-using component. When the first connecting mechanism 1 and the second connecting mechanism body 2 are plugged and fixed, the first electrical connection structure 12 and the second electrical connection structure 22 are plugged in, and the first air connection structure 11 and the second air connection structure 21 are plugged in, thereby making the power supply device electrically connected to the electrical load and the air source device connected to the air-using component.

[0022] like Figure 1-3As shown, the first connecting mechanism 1 can be arranged on the car seat, such as the seat back 4, seat cushion, seat leg rest, seat headrest 5, back panel, or side panel, or any other position where it can be installed. The first connecting mechanism 1 can also be placed in a receiving groove formed in the seat frame, plastic parts, or seat foam. It is used to connect the independent power supply and air supply devices of the car seat, or the power supply and air supply devices of the entire vehicle. The first electrical connection structure 12 and the first air connection structure 11 can be integrally molded onto the first main body by injection molding, or they can be integrally molded onto the first main body with an installation structure. The connecting structure 12 and the first air passage connecting structure 11 are respectively fixed to the mounting structure by means of snap-fit, adhesive, or threaded connection. In this embodiment, the first air passage connecting structure 11 is integrally formed with the first body 1, and the mounting structure is a mounting groove that penetrates the first body 1. The first electrical connecting structure 12 is embedded in the mounting groove and fixed to the first body 1. In other embodiments of this application, other connection methods can also be used between the first body 1 and the first electrical connecting structure 12 and the first air passage connecting structure 11, which are not specifically limited here; furthermore, the first electrical connecting structure 12 and the first air passage connecting structure 11 are fixed to the mounting structure 11 by means of snap-fit, adhesive, or threaded connection. The number of connection structures 11 can be adjusted according to the number of air and electrical connections in the seat rest pillow 6; the second connection mechanism 2 is disposed on the seat rest pillow 6 and can be plugged and fixed with the first connection mechanism 1. The second connection mechanism 2 is used to connect the electrical load and the air-using components in the seat rest pillow 6. The electrical load may be a heating pad, ventilation fan, adjustment device, mechanical massage device or audio device disposed in the seat rest pillow 6, etc., and the air-using components may be a massage airbag or support airbag disposed in the seat rest pillow 6, etc.; the second electrical connection structure 22 and the second air connection structure 21 are connected to the second main body 2. Alternatively, the above method can be used, with the number of second electrical connection structures 22 being the same as the number of first electrical connection structures 12, and the number of second air connection structures 21 being the same as the number of first air connection structures 11; the first connection mechanism 1 and the second connection mechanism 2 are detachably connected. When the first connection mechanism 1 and the second connection mechanism 2 are plugged and fixed, the first electrical connection structure 12 is plugged into the corresponding second electrical connection structure 22, so that the power supply device is electrically connected to the electrical load, and the first air connection structure 11 is plugged into the corresponding second air connection structure 21, so that the air source device is connected to the air-using component.

[0023] like Figure 8-10As shown, in this embodiment, the seat-attached pillow 6 is a soft headrest attached to the side of the seat headrest 5 closest to the human body. The seat headrest 5 is inserted into the seat backrest 4. The top of the seat backrest 4 has a receiving groove. The first connecting mechanism 1 is fixed in the receiving groove. The first electrical connection structure 12 and the first air connection structure 11 in the first connecting mechanism 1 are respectively connected to a power supply device and an air supply device located inside the seat backrest 4. The second connecting mechanism 2 is located on the seat-attached pillow 6. The second connecting mechanism 2 can move within a certain range relative to the seat-attached pillow 6. When the seat-attached pillow 6 is inserted together with the seat headrest 5... When installed on the seat back 4, the second connecting mechanism 2 can be inserted and fixed to the first connecting mechanism 1 at the top of the seat back 4, thereby connecting the electrical load and air supply components in the seat pillow 6 to the power supply device and air supply device respectively. In other embodiments, the first connecting mechanism 1 can also be located on the seat headrest 5, for example, below the seat headrest 5. In this case, the first electrical connection structure 12 and the first air passage connection structure 11 can pass through the headrest rod and connect to the power supply device and air supply device located inside the seat back 4. Alternatively, the power supply device and air supply device can be located inside the seat headrest 5. No special limitation is made here.

[0024] By simultaneously setting electric and pneumatic connection structures on the first and second main bodies, when the first connection mechanism 1 and the second connection mechanism 2 are plugged in and fixed, the corresponding electric and pneumatic connection structures are plugged in respectively, thereby realizing the integrated synchronous connection of the circuit and the air circuit. Compared with the traditional separate connection of the circuit and the air circuit, the operation is simpler and more efficient, which can effectively improve the user experience.

[0025] 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.

[0026] like Figure 4-6As 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 electrical connection structure that can support multiple 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 integrally injection molded with the first body or manufactured separately and then 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 integrally injection molded with the second body or manufactured separately and then fixed. When the first connecting mechanism 1 is plugged into the second connecting mechanism 2, 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.

[0027] 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.

[0028] like Figure 1 , Figure 4 and Figure 6As shown, a first pneumatic plug 111 and a first air nozzle 112 are integrally formed at both ends of a first main body. A first air passage 113 passes through the first main body and connects to the first pneumatic plug 111 and the first air nozzle 112 respectively. The first air nozzle 112 is connected to an air source device via a first air tube. A second pneumatic plug 211 and a second air nozzle 212 are integrally formed at both ends of a second main body. A second air passage 213 passes through the second main body and connects to the second pneumatic plug 211 and the second air nozzle 212 respectively. The second air nozzle 212 is connected to an air source device via a second air tube. In this embodiment, the second air... The extension direction of the 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 1 is inserted into the second connecting mechanism 2, 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.

[0029] In a preferred embodiment, the first body also has a first connecting portion 15, which is used to fix to the car seat.

[0030] like Figure 4-6 As shown, the first main body includes a first connecting part 15 and a first insert part. The first connecting part 15 is approximately a flat plate structure and is arranged around the first insert part. The first connecting part 15 has multiple connecting holes for fixing the first main body to the car seat. The first insert part is provided with the aforementioned first electrical connection structure 12 and first air passage connection structure 11. The second main body includes a second connecting part 25 and a second insert part. The second connecting part 25 is also approximately a flat plate structure and is arranged around the second insert part. The second insert part is provided with the aforementioned second electrical connection structure 22 and second air passage connection structure 21.

[0031] Furthermore, the ends of the first insertion part and the second insertion part can be fitted with elastic sealing members to seal the first pneumatic plug 111 and the first electric plug 121, as well as the second pneumatic plug 211 and the second electric plug 221, when the first connecting mechanism 1 and the second connecting mechanism 2 are not inserted and connected, so as to prevent dust, water vapor and other impurities from entering.

[0032] In a preferred embodiment, the first body has a first guide structure 13 and the second body has a second guide structure 23, the outline of the first guide structure 13 matching the outline of the second guide structure 23.

[0033] like Figure 4 and Figure 6As shown, the first guide structure 13 is approximately cylindrical, formed on the outer periphery of the first insert portion and located on one side of the first connecting portion 15; the second guide structure 23 is also approximately cylindrical, formed on the outer periphery of the second insert portion and located on one side of the second connecting portion 25; by interlocking the first guide structure 13 and the second guide structure 23, the first connecting mechanism 1 and the second connecting mechanism 2 are interlocked and fixed.

[0034] In a preferred embodiment, the first main body is provided with a plurality of first snap-fit ​​structures, and the second main body is provided with a second snap-fit ​​structure corresponding to the first snap-fit ​​structure; when the first connecting mechanism 1 is inserted into the second connecting mechanism 2, the first snap-fit ​​structure and the second snap-fit ​​structure are snap-fitted and fixed.

[0035] like Figure 4 , Figure 6 and Figure 7 As shown, the first snap-fit ​​structure can adopt a snap-fit ​​member 14 or a snap-fit ​​hole 24, and the second snap-fit ​​structure adopts a snap-fit ​​hole 24 or a snap-fit ​​member 14 corresponding to the first snap-fit ​​structure. In this embodiment, multiple snap-fit ​​members 14 are provided on the first insertion part. The snap-fit ​​member 14 is approximately a wedge-shaped protrusion. The snap-fit ​​hole 24 is opened on the second insertion part corresponding to the snap-fit ​​member 14. By snapping and engaging the snap-fit ​​member 14 with the snap-fit ​​hole 24, the first connecting mechanism 1 and the second connecting mechanism body 2 can be quickly inserted and removed. The distance between the end of the snap-fit ​​member 14 near the first pneumatic plug 111 and the highest point of the protrusion on the first insertion part is greater than the distance between the end of the snap-fit ​​member 14 away from the first pneumatic plug 111 and the highest point of the protrusion on the first insertion part. That is, the angle of the snap-fit ​​member 14 near the first pneumatic plug 111 is smaller than the angle of the end away from the first pneumatic plug 111. Therefore, the force required to insert the first connecting mechanism 1 into the second connecting mechanism 2 is less than the force required to pull the first connecting mechanism 1 out of the second connecting mechanism 2.

[0036] In a preferred embodiment, when the first connecting mechanism 1 and the second connecting mechanism 2 are plugged in, the overlapping portion of the two has a first length A in the plugging direction; when the second pneumatic plug 211 and the first pneumatic plug 111 are plugged in, the overlapping portion of the two has a second length B in the plugging direction; and when the second electric plug 221 and the first electric plug 121 are plugged in, the overlapping portion of the two has a third length C in the plugging direction. The first length A is greater than the second length B and the third length C.

[0037] like Figure 1As shown, the first length A is the length of the overlapping portion of the first guide structure 13 and the second guide structure 23 when the first connecting mechanism 1 and the second connecting mechanism 2 are inserted and fixed; the second length B is the length of the overlapping portion of the second pneumatic plug 211 and the first pneumatic plug 111 when the first connecting mechanism 1 and the second connecting mechanism 2 are inserted and fixed; and the third length C is the length of the overlapping portion of the second electric plug 221 and the first electric plug 121 when the first connecting mechanism 1 and the second connecting mechanism 2 are inserted and fixed. By making the first length A greater than the second length B greater than the third length C, after the first guide structure 13 and the second guide structure 23 are snapped and fixed, it can be determined that both the pneumatic connection and the electrical connection are inserted in place, thus achieving a stable connection between the pneumatic circuit and the electrical circuit.

[0038] 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.

[0039] like Figure 1 and Figure 2 As shown, in this embodiment, the first pneumatic plug 111 has a concave structure, and the second pneumatic plug 211 has a convex structure. During connection, the second pneumatic plug 211 is inserted into the first pneumatic plug 111. The sealing structure is located inside the first pneumatic plug 111. 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 and second pneumatic plugs 111, thus achieving 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 each other. Near the first air nozzle 112, the first sealing ring 114 has a snap-fit ​​protrusion on its outer periphery, which 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.

[0040] 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.

[0041] like Figure 2As 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.

[0042] In a preferred embodiment, a third body 3 is further included, which is fixed to the second body.

[0043] like Figure 3 As shown, the third body 3 is approximately a flat plate structure. The third body 3 can be inserted into the second connecting part 25 of the second body and fixed to the second body by hot riveting. The third body 3 and the second connecting part 25 can cooperate with each other to clamp onto the cover of the seat pillow 6. Furthermore, the second body may not be provided with the third body 3, and the second body can be connected to the seat pillow 6 through the second connecting part 25.
