[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] (1) The utility model relates to a quick plug-in and pull-out structure of an air bag massage headrest and a car seat. By connecting an air pipe plug to the end of a headrest support rod, when the headrest support rod is connected to a seat frame, the air pipe plug can be plugged into a socket, and the plug-in surface can be pressed against the plug-in hole to ensure quick connection between the first air pipe and the second air pipe. Similarly, when the massage headrest and the seat frame are separated, the air pipe plug can be driven out of the socket by the headrest support rod to disconnect the connection between the first air pipe and the second air pipe, thereby realizing the quick plug-in and pull-out function of the headrest. At the same time, the sealing member wrapped on the outside of the plug-in surface can ensure the sealing effect of the air pipe plug and the air pipe socket during the quick plug-in and pull-out process of the headrest, thereby ensuring the normal use of the air bag massage headrest and improving the user experience.

[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0034] like Figure 1 As shown, in the present solution, a quick plug-in and pull-out structure of an air bag massage headrest used in a car seat is mainly described in detail, but the quick plug-in and pull-out structure of the air bag massage headrest is not limited to being used in car seats, but can also be applied to other seats, such as e-sports seats in life.

[0035] like Figures 1 to 3 As shown, a quick plug-in structure of an air bag massage headrest comprises: a headrest support rod 2 for connecting the massage headrest; an air pipe plug 3, which is detachably connected to the end of the headrest support rod 2, one end of the air pipe plug 3 is connected to a first air pipe 30 extending into the massage headrest, and the other end is formed with a plug-in surface 31; an air pipe socket 4, which is detachably connected to the seat frame 1, and the air pipe socket 4 is movably provided with a plug-in seat 40, and the plug-in seat 40 is connected to a second air pipe 41 extending into the seat, and the plug-in seat 40 is connected to the second air pipe 41 extending into the seat. A plug hole 42 is formed inside, and the trachea plug 3 is movably plugged into the plug seat 40 so that the plug surface 31 is pressed against the plug hole 42; the sealing member 5 is wrapped around the plug surface 31 and is used to movably press against the inner wall of the plug hole 42 to prevent air leakage when the first trachea 30 is connected to the second trachea 41; when the trachea plug 3 is separated from the trachea socket 4, the headrest support rod 2 can drive the trachea plug 3 away from the trachea socket 4 along with the massage headrest to achieve the disconnection and connection between the first trachea 30 and the second trachea 41.

[0036] This solution mainly realizes the function of quick plugging and unplugging of the headrest in the air bag massage headrest. Specifically, since the air pipe plug 3 is connected to the end of the headrest support rod 2 in this solution, when the massage headrest needs to be removed from the seat frame 1, the massage headrest can drive the air pipe plug 3 to detach from the seat frame 1 through the headrest support rod 2. It is worth noting that the first air pipe 30 connected to the air bag massage device in the massage headrest is connected to the air pipe plug 3, and the second pipe connected to the inflation device in the seat is connected to the socket 40, and the air pipe plug 3 and the socket 40 are both provided with through holes (not shown in the figure). Figure 2As shown, when the headrest support rod 2 drives the trachea plug 3 to approach the trachea socket 4, the trachea plug 3 can be plugged into the socket 40, so that the plug-in surface 31 formed at the end of the trachea plug 3 can be movably pressed against the plug-in hole 42, ensuring that the first trachea 30 and the second trachea 41 are quickly connected using the through hole. Similarly, when the massage headrest drives the headrest support rod 2 to separate from the seat frame 1, the headrest support rod 2 can drive the trachea plug 3 to separate from the socket 40 to achieve rapid disconnection of the first trachea 30 and the second trachea 41. Therefore, this structure effectively realizes the function of quick plug-in and pull-out of the headrest, provides convenience for the disassembly and installation of the massage headrest, and at the same time, uses the sealing member 5 wrapped around the outside of the plug-in surface 31 to ensure the sealing effect of the trachea plug 3 and the socket 40 when plugged in during the quick plug-in and pull-out process of the headrest, ensuring the normal use of the air bag massage headrest and greatly improving the customer's user experience.

[0037] A connecting portion 32 and a limiting portion 33 are formed on the tracheal plug 3 . The connecting portion 32 is used to extend into the interior of the headrest support rod 2 and be threadedly connected thereto; the limiting portion 33 is movably pressed against the end of the headrest support rod 2 .

[0038] like Figure 2 As shown, the limiting portion 33 is located at the bottom of the connecting portion 32. When the connecting portion 32 is connected to the end of the headrest support rod 2, the limiting portion 33 can limit the position of the tracheal plug 3 connected to the headrest support rod 2, that is, when the limiting portion 33 is pressed against the end of the headrest support rod 2, it means that this is the limit position of the connection between the connecting portion 32 and the headrest support rod 2, thereby giving the worker a signal indication that the tracheal plug 3 is installed in place, ensuring the stability of the tracheal plug 3 during assembly. In addition, the connecting portion 32 in this solution is connected to the hollow headrest support rod 2 by a threaded connection, but this is not limited to one method in this embodiment, and other methods such as laser welding can also be used instead.

[0039] Preferably, the top of the tracheal plug 3 and the end of the socket 40 in this solution are both formed with a buckle portion 34, such as Figure 2 As shown, the buckle portion 34 extends into the first air pipe 30 or the second air pipe 41 to achieve a movable snap-on connection mode, which is simple to operate and convenient for workers to install and disassemble. Further, a sealing ring (not shown in the figure) can be provided at the connection position between the buckle portion 34 and the air pipe to ensure that the air pipe achieves the required sealing effect on the gas. In addition, the connection between the buckle portion 34 and the air pipe can also be replaced by other methods such as gluing.

[0040] The plug-in surface 31 is recessed along the interior of the tracheal plug 3 and forms a mounting groove 310 . The sealing member 5 is disposed in the mounting groove 310 and movably abuts against the limiting portion 33 .

[0041] like Figure 2As shown, the installation groove 310 is formed at the position of the plug-in surface 31 close to the above-mentioned limiting portion 33. The installation groove 310 can limit the seal 5 during installation, preventing the seal 5 from being separated from the tracheal plug 3 during the plug-in process. When the seal 5 is placed in the installation groove 310, the top of the seal 5 is pressed against the limiting portion 33, and the limiting portion 33 further positions and installs the seal 5. It is worth noting that there is no concave phenomenon at the position of the plug-in surface 31 close to the end of the plug-in hole 42. Such a design is conducive to guiding the plug-in of the tracheal plug 3 through the end of the plug-in surface 31, thereby ensuring the smoothness and stability of the plug-in surface 31 when it is movably plugged and pressed against the inner wall of the plug-in hole 42. Preferably, the seal 5 in this solution can be replaced by other sealing devices such as sealing rings and O-rings.

[0042] The plug hole 42 includes a guide portion 420 and a locking portion 421 arranged at an angle. The guide portion 420 is used to guide the tracheal plug 3 to move along the inside of the socket 40 so that the plug surface 31 can move against the locking portion 421 to achieve communication between the first trachea 30 and the second trachea 41.

[0043] Continue to refer Figure 2 The guide portion 420 is located above the locking portion 421 and close to the top of the tracheal socket 4. Since the opening diameter of the guide portion 420 is much larger than the opening diameter of the locking portion 421, the guide portion 420 can provide a guiding effect when the tracheal plug 3 is plugged in during the plugging process of the tracheal plug 3, ensuring that the tracheal plug 3 can be smoothly plugged in along the direction of the locking portion 421. Preferably, the locking portion 421, the plugging surface 31 and the sealing member 5 in this solution are all arranged in a bell-mouth shape, such as Figure 2 As shown in the figure, the locking portion 421 is arranged at the large end opening of the tracheal plug 3 facing upward, so as the locking portion 421 continues to guide the tracheal plug 3 when plugging, the plugging surface 31 on the tracheal plug 3 can drive the sealing member 5 to be closely attached to the inner wall of the locking portion 421, and at the same time, the tracheal plug 3 is finally restricted to the locking portion 421 by utilizing the characteristics of the trumpet-shaped cone. Figure 2 At the position shown, the first air pipe 30 and the second air pipe 41 are quickly connected.

[0044] It is worth noting that when the above-mentioned trachea plug 3 is inserted into the locking portion 421, the end of the plug-in surface 31 plays a guiding role during the initial plug-in action, and after the plug-in action is completed, the trachea plug 3 mainly relies on the sealing member 5 to press against the inside of the locking portion 421, thereby playing a sealing effect on the first trachea 30 and the second trachea 41 after the connection. At the same time, the friction between the sealing member 5 and the locking portion 421 is used to ensure the stability of the trachea plug 3 and the socket 40 after plugging.

[0045] The trachea socket 4 also includes: a detachably connected fixing sleeve 43 and a plug-in guide sleeve 44, the fixing sleeve 43 is detachably connected to the seat frame 1, the fixing sleeve 43 and the plug-in guide sleeve 44 together form a guide hole 45, and the plug-in socket 40 is movably arranged in the guide hole 45; an elastic member 46, which is arranged in the vertical direction, one end of the elastic member 46 is connected to the bottom wall of the guide hole 45, and the other end is movably pressed against the plug-in socket 40, so that the plug-in socket 40 can move back and forth along the axial direction of the guide hole 45.

[0046] like Figure 2 and Figure 3 As shown, the fixing sleeve 43 and the plug-in guide sleeve 44 in this solution can be detachably connected by screws, bolts or other connecting members, which provides convenience for the subsequent maintenance and replacement of parts in the guide hole 45; in addition, the plug-in seat 40 and the elastic member 46 are both arranged along the axial direction of the guide hole 45 (i.e. Figure 2 In the vertical direction), since the socket 40 and the guide hole 45 are both arranged in a stepped shape, when the socket 40 is pressed against the step of the guide hole 45 (such as Figure 2 The guide hole 45 can play a certain guiding and limiting role in the movement of the socket 40, thereby providing a guarantee for the accurate and stable plugging of the trachea plug 3 and the socket 40. Combined with the elastic deformation ability of the elastic member 46, it is effectively ensured that the plugging direction of the trachea plug 3 when plugged into the socket 40 is consistent with the moving direction of the socket 40 when the elastic member 46 is elastically deformed, thereby satisfying the buffering effect required during the plugging, and avoiding the rigid plugging of the trachea plug 3 and the socket 40, which is easy to cause damage.

[0047] Furthermore, in the present embodiment, a guide block 400 is formed on the outer wall of the socket 40, and a guide groove 441 is formed in the plug guide sleeve 44. When the tracheal plug 3 is plugged into the socket 40, the guide block 400 is movably engaged in the guide groove 441 to guide the socket 40 to reciprocate along the axial direction of the guide hole 45, thereby causing the elastic member 46 to move along the axial direction of the guide hole 45. Figure 2 The required cushioning effect is achieved by squeezing and contracting vertically downward, ensuring smoothness and stability during the plug-in process.

[0048] Similarly, if Figure 2 As shown, during the installation and connection process of the above-mentioned fixing sleeve 43 and the plug-in guide sleeve 44, the positioning groove 430 on the fixing sleeve 43 is movably inserted into the positioning block 440 of the plug-in guide sleeve 44, which plays a pre-positioning effect for the installation between the two, effectively avoiding the plug-in guide sleeve 44 from rotating relative to the fixing sleeve 43 and affecting the smoothness of subsequent screw or bolt connections, thereby improving the overall stability of the quick plug-in structure.

[0049] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0050] In addition, in the present invention, the descriptions of "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0051] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
