Detailed Implementation

[0045] The technical solutions of the present invention will now be described with reference to the accompanying drawings in the embodiments of the present invention.

[0046] The embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. The invention will be described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the invention.

[0047] For headrests equipped with pneumatic headrest functionality, the headrest is connected to the seat body via an air tube. However, due to the design of the air tube connecting the headrest and the seat body, it is difficult to freely detach and install the headrest. To solve the above problem, this utility model embodiment provides a headrest detachment structure, a seat assembly, and a vehicle. The headrest detachment structure, seat assembly, and vehicle mentioned above are described in detail below.

[0048] Firstly, referring to Figures 1 to 4 , Figure 7 and Figure 8 The headrest assembly / disassembly structure provided in this embodiment includes a headrest rod 1, a receiving insert 2, an air pipe assembly 6, and an air guide docking assembly 3. The headrest rod 1 is connected to the headrest body 8 and includes a first branch rod 11. The receiving insert 2 is disposed on the seat body and the headrest rod 1 is inserted into the receiving insert 2. The air pipe assembly 6 is disposed in the first branch rod 11 and includes a first air pipe 61 and a first air connector 62 connected to the first air pipe 61. The air guide docking assembly 3 is disposed on the seat body and includes a second air pipe 32 and a second air connector 31 connected to the second air pipe 32. When the headrest rod 1 is inserted into the receiving insert 2, the first air connector 62 and the second air connector 31 are inserted and engaged.

[0049] The seat headrest includes the aforementioned headrest rod 1, air tube assembly 6, and headrest body 8. The headrest body 8 may include a headrest frame 81 and a headrest cover 82, with the headrest cover 82 fitted over the headrest frame 81. The headrest rod 1 is specifically connected to the headrest frame 81. The seat body includes a backrest frame 9 and a fixing tube 10 connected to the backrest frame 9. The receiving insert 2 may be disposed within the fixing tube 10.

[0050] As an example, when the headrest rod 1 is inserted into the receiving plug 2, the second gas connector 31 is inserted into the first gas connector 62. In this example, the first gas connector 62 has a first socket, and the second gas connector 31 has a first plug 312; when the headrest rod 1 is inserted into the receiving plug 2, the first plug 312 in the second gas connector 31 is inserted into the first socket in the first gas connector 62.

[0051] As another example, when the headrest rod 1 is inserted into the receiving plug 2, the first gas connector 62 is inserted into the second gas connector 31. In this example, the first gas connector 62 has a second plug, and the second gas connector 31 has a second socket; when the headrest rod 1 is inserted into the receiving plug 2, the second plug in the first gas connector 62 is inserted into the second socket in the second gas connector 31.

[0052] The first branch rod 11 is a hollow rod. During installation, the air tube assembly 6 can be inserted through the bottom opening of the first branch rod 11. After the air tube assembly 6 is fully inserted, the bottom of the first air connector 62 can be fixedly connected to the first branch rod 11 using structural adhesive. The side surface of the first air connector 62 may have a barbed structure for engaging with the inner wall of the first branch rod 11. The first air connector 62 can be inserted into or fixedly connected to the end of the first air tube 61. The second air connector 31 can be inserted into or fixedly connected to the end of the second air tube 32.

[0053] The position of the air guide docking component 3 corresponds to the position of the receiving plug 2, and the air guide docking component 3 is preferably located on the lower side of the receiving plug 2. During the process of the headrest rod 1 being inserted downward into the receiving plug 2, the first branch rod 11 is located inside the receiving plug 2, the air tube assembly 6 is located inside the first branch rod 11, and the first air connector 62 in the air tube assembly 6 moves downward and gradually approaches the second air connector 31 until the headrest rod 1 is inserted into place, at which point the first air connector 62 and the second air connector 31 are inserted and engaged.

[0054] After the first air connector 62 and the second air connector 31 are inserted and engaged, the second air connector 31 is connected to the first air connector 62. The second air pipe 32 is connected to the first air pipe 61 through the second air connector 31 and the first air connector 62. The gas in the second air pipe 32 can be delivered to the first air pipe 61, thereby realizing the pneumatic headrest functions such as pneumatic massage, pneumatic headrest adjustment, and sleep headrest adjustment.

[0055] In this embodiment of the invention, during the upward pulling of the headrest rod 1, the first gas connector 62 moves upward along with the headrest rod 1. After moving upward, the first gas connector 62 disengages from the second gas connector 31, thereby achieving the removal of the seat headrest. During the downward insertion of the headrest rod 1, the first gas connector 62 moves downward along with the headrest rod 1. When the headrest rod 1 is inserted into place, the first gas connector 62 and the second gas connector 31 engage, thereby achieving the installation of the seat headrest. Therefore, through the above-described headrest disassembly and assembly structure, the pneumatic headrest function is realized, and the free disassembly and assembly of the seat headrest can be achieved. In addition, this headrest disassembly and assembly structure is compatible with the "double bed mode," which means that after the headrest of the front seat is removed, the backrest of the front seat is adjusted backward until the backrest of the front seat connects with the seat cushion of the rear seat to form a double bed state. Furthermore, when removing the headrest, simply pull the headrest rod 1 out of the receiving plug 2; when installing the headrest, simply insert the headrest rod 1 into the receiving plug 2. The removal and installation of the headrest are convenient. In addition, the air pipe assembly 6 is located within the first branch rod 11, eliminating the need to change the structure of the headrest body 8. This avoids the need to modify the corresponding production equipment for the headrest body 8, saving on equipment modification costs.

[0056] In an optional embodiment of this utility model, reference is made to Figure 3 , Figures 5 to 7 , Figure 9 The headrest rod 1 also includes a second branch rod 12 disposed opposite to the first branch rod 11. The headrest assembly and disassembly structure also includes a wire assembly 7, which is disposed within the second branch rod 12. The wire assembly 7 includes a first wire 71 and a first electrical connector 72 electrically connected to the first wire 71. The headrest assembly and disassembly structure also includes an electrical connection assembly 4, which is disposed on the seat body. The electrical connection assembly 4 includes a second wire 42 and a second electrical connector 41 electrically connected to the second wire 42. When the headrest rod 1 is inserted into the receiving plug 2, the first electrical connector 72 and the second electrical connector 41 are inserted and engaged.

[0057] The first electrical connector 72 can be fixedly connected to the end of the first wire 71, and the second electrical connector 41 can be fixedly connected to the end of the second wire 42. During installation, the wire assembly 7 can be inserted through the bottom opening of the second branch rod 12. After insertion, the first electrical connector 72 can be fixed inside the second branch rod 12 using barbed structures and structural adhesive. After the first electrical connector 72 and the second electrical connector 41 are plugged in and engaged, the second electrical connector 41 is electrically connected to the first electrical connector 72. The second wire 42 is electrically connected to the first wire 71 through the second electrical connector 41 and the first electrical connector 72. The power and electrical signals transmitted by the second wire 42 can be transmitted to the first wire 71, thereby enabling the functions of an electric headrest, such as an electric headrest, headrest speaker, and headrest heating.

[0058] As an example, when the headrest rod 1 is inserted into the receiving plug 2, the second electrical connector 41 is inserted into the first electrical connector 72. In this example, the first electrical connector 72 has a third socket, and the second electrical connector 41 has a third plug 412; when the headrest rod 1 is inserted into the receiving plug 2, the third plug 412 in the second electrical connector 41 is inserted into the third socket in the first electrical connector 72.

[0059] As another example, when the headrest rod 1 is inserted into the receiving plug 2, the first electrical connector 72 is inserted into the second electrical connector 41. In this example, the first electrical connector 72 has a fourth plug, and the second electrical connector 41 has a fourth socket.

[0060] When the headrest rod 1 is inserted into the receiving plug 2, the fourth plug in the first electrical connector 72 is inserted into the fourth socket in the second electrical connector 41.

[0061] In related technologies, headrests equipped with electric headrests, headrest speakers, headrest heating, and other electric headrest functions are connected to the seat body via wiring harnesses. However, due to the wiring harness used to connect the headrest and the seat body, it is difficult to freely disassemble and install the headrest. In this embodiment of the present invention, during the upward pulling of the headrest rod 1, the first electrical connector 72 moves upward along with the headrest rod 1. After moving upward, the first electrical connector 72 disengages from the second electrical connector 41, thereby achieving the disassembly of the seat headrest. During the downward insertion of the headrest rod 1, the first electrical connector 72 moves downward along with the headrest rod 1. When the headrest rod 1 is inserted into place, the first electrical connector 72 and the second electrical connector 41 engage, thereby achieving the installation of the seat headrest. Therefore, through the above-described headrest disassembly and assembly structure, the free disassembly and assembly of the seat headrest can be achieved while realizing the electric headrest function.

[0062] In an optional embodiment of this utility model, reference is made to Figure 4 , Figure 5 , Figures 8 to 11 The air guiding docking assembly 3 also includes a first docking fixing seat 33 and a first elastic member 34. The first docking fixing seat 33 is disposed on the seat body. The second air connector 31 is movably connected to the first docking fixing seat 33 along the insertion and removal direction of the headrest rod 1. The two ends of the first elastic member 34 are respectively connected to the second air connector 31 and the first docking fixing seat 33.

[0063] The electrical connection assembly 4 also includes a second docking fixing seat 43 and a second elastic member 44. The second docking fixing seat 43 is disposed on the seat body. The second electrical connector 41 is movably connected in the second docking fixing seat 43 along the insertion and removal direction of the headrest rod 1. The two ends of the second elastic member 44 are respectively connected to the second electrical connector 41 and the second docking fixing seat 43.

[0064] The first elastic element 34 and the second elastic element 44 can be springs, and the insertion and removal direction of the headrest rod 1 can be referred to Figure 4 and Figure 5 The direction indicated by arrow D. The second gas connector 31 can move relative to the first mating fixing seat 33 along the insertion / removal direction of the headrest rod 1, and the second electrical connector 41 can move relative to the second mating fixing seat 43 along the insertion / removal direction of the headrest rod 1. Preferably, when the headrest rod 1 is inserted into place, both the first elastic member 34 and the second elastic member 44 are in a compressed state. The first elastic member 34 can apply an upward force to the second gas connector 31, thereby ensuring a tight fit between the second gas connector 31 and the first gas connector 62 and avoiding poor mating due to assembly errors. The second elastic member 44 can apply an upward force to the second electrical connector 41, thereby ensuring a tight fit between the second electrical connector 41 and the first electrical connector 72.

[0065] In an optional embodiment of this utility model, reference is made to Figures 8 to 11 The first docking fixing seat 33 has a first slot 331, and the second gas connector 31 has a first buckle 311. The first buckle 311 is movably engaged in the first slot 331 along the insertion and removal direction of the headrest rod 1. The second docking fixing seat 43 has a third slot 431, and the second electrical connector 41 has a third buckle 411. The third buckle 411 is movably engaged in the third slot 431 along the insertion and removal direction of the headrest rod 1.

[0066] First, the second gas connector 31 can be connected to the second gas pipe 32. Then, the second gas pipe 32 can be passed through the first docking fixing seat 33, and the second gas connector 31 can be installed in the first docking fixing seat 33. When installing the second gas connector 31, the second gas connector 31 is inserted into the first docking fixing seat 33 from top to bottom until the first buckle 311 is engaged in the first slot 331.

[0067] First, connect the second electrical connector 41 to the second wire 42. Then, pass the second wire 42 through the second mating fixing seat 43 and install the second electrical connector 41 inside the second mating fixing seat 43. Finally, connect the plug to the end of the second wire 42 away from the second electrical connector 41. When installing the second electrical connector 41, insert the second electrical connector 41 into the second mating fixing seat 43 from top to bottom until the third buckle 411 is engaged in the third slot 431.

[0068] In this embodiment, the first latch 311 and the first slot 331 enable the connection between the second gas connector 31 and the first docking fixing seat 33, and also limit the range of motion of the second gas connector 31, preventing it from detaching from the first docking fixing seat 33. Similarly, the third latch 411 and the third slot 431 enable the connection between the second electrical connector 41 and the second docking fixing seat 43, and also limit the range of motion of the second electrical connector 41, preventing it from detaching from the second docking fixing seat 43.

[0069] In other embodiments, the first docking fixing seat 33 has a second buckle, and the second gas connector 31 has a second slot.

[0072] In an optional embodiment of this utility model, reference is made to Figure 6 The receiving plug 2 includes a first receiving plug 21 and a second receiving plug 22, which are detachably connected to the first fixed insertion tube 101 and the second fixed insertion tube 102, respectively; a first branch rod 11 is used to be inserted into the first receiving plug 21, and a second branch rod 12 is used to be inserted into the second receiving plug 22; the first docking fixing seat is located below the first receiving plug, and the second docking fixing seat is located below the second receiving plug.

[0073] In this embodiment, the first receiving plug 21 and the second receiving plug 22 are respectively snapped into the first fixed insertion tube 101 and the second fixed insertion tube 102. The first fixed insertion tube 101 has a seventh slot, and the bottom of the first receiving plug 21 has a seventh latch 211, which engages in the seventh slot to restrict the axial position of the first receiving plug 21 along the first fixed insertion tube 101. The second fixed insertion tube 102 has an eighth slot, and the bottom of the second receiving plug 22 has an eighth latch 221, which engages in the eighth slot to restrict the axial position of the second receiving plug 22 along the second fixed insertion tube 102. In this embodiment, the first receiving plug 21 and the second receiving plug 22 are respectively snapped into the first fixed insertion tube 101 and the second fixed insertion tube 102, facilitating the disassembly and installation of the first receiving plug 21 and the second receiving plug 22.

[0074] In an optional embodiment of this utility model, reference is made to Figure 5 The headrest rod 1 has a slot, and the insert 2 includes a guide sleeve body and a locking plate 23 movably connected to the guide sleeve body. The locking plate 23 is used to insert into the slot.

[0075] The locking stop plate 23 is connected to the guide sleeve body via a third elastic element, which is located on the same side as the locking stop plate 23. The third elastic element can be a spring. The receiving plug 2 may also include a pressing unlocking component connected to the locking stop plate 23. When the pressing unlocking component is not subjected to external force, the third elastic element is not stressed, and the locking stop plate 23 is inserted into the slot. When the pressing unlocking component is pressed, it will drive the locking stop plate 23 to move away from the slot, so that the locking stop plate 23 is disengaged from the slot. At this time, the third elastic element is compressed. It should be noted that the position of the pressing unlocking component is preferably opposite to the position of the locking stop plate 23. When the pressing unlocking component is pressed, it moves toward the side where the locking stop plate 23 is located, thereby driving the locking stop plate 23 to move away from the slot. After the pressing unlocking component is released and the headrest rod 1 is completely pulled out, the locking stop plate 23 returns to its original position under the action of the third elastic element. In this embodiment, the headrest rod 1 can be stably fixed by the cooperation of the locking baffle 23 and the slot.

[0076] The assembly process of the above-mentioned headrest disassembly and assembly structure can be as follows: First, the first fixing tube 101 and the second fixing tube 102 are welded to the backrest frame 9. Then, the air guide docking assembly 3 and the power connection docking assembly 4 are respectively snapped into the bottom of the first fixing tube 101 and the second fixing tube 102. Then, the first receiving plug 21 and the second receiving plug 22 are respectively snapped into the first fixing tube 101 and the second fixing tube 102. Finally, the first branch rod 11 and the second branch rod 12 in the headrest rod 1 are respectively inserted into the first receiving plug 21 and the second receiving plug 22 along the headrest rod insertion direction. When the headrest rod 1 is inserted into the position, the locking baffle 23 is inserted into the slot to achieve stable fixation of the headrest rod 1.

[0077] During the assembly of the headrest disassembly structure, the fifth buckle 332 of the air guide docking assembly 3 engages with the fifth slot at the bottom of the first fixed insertion tube 101; the sixth buckle 432 of the power connection docking assembly 4 engages with the sixth slot at the bottom of the second fixed insertion tube 102; the seventh buckle 211 at the bottom of the first receiving insertion tube 21 engages with the seventh slot at the first fixed insertion tube 101; and the eighth buckle 221 at the bottom of the second receiving insertion tube 22 engages with the eighth slot at the second fixed insertion tube 102.

[0078] Secondly, this utility model embodiment provides a seat assembly, which includes a headrest body 8, a seat body, and the headrest detachment structure provided in the first aspect. Since the seat assembly includes the aforementioned headrest detachment structure, it also possesses the beneficial effects of the aforementioned headrest detachment structure, which will not be elaborated further here.

[0079] In an optional embodiment of this utility model, reference is made to Figure 7 Along the length of the headrest rod 1, multiple adjustment slots 13 are provided on the headrest rod 1. The headrest body 8 includes a headrest frame 81, a locking component movably connected to the headrest frame 81, and an unlocking component connected to the locking component. The locking component is used to be inserted into any one of the adjustment slots 13, and the unlocking component is used to disengage the locking component from the adjustment slot 13 under the action of external force.

[0080] The locking mechanism is connected to the headrest frame 81 via a fourth elastic element, which is located on the same side as the locking mechanism. The fourth elastic element can be a spring. When the unlocking mechanism is not subjected to external force, the fourth elastic element is unloaded, and the locking mechanism is inserted into one of the adjustment slots 13. When the unlocking mechanism is subjected to external force, causing the locking mechanism to move away from the adjustment slot 13, the fourth elastic element is compressed. After the unlocking mechanism is released, the locking mechanism resets under the action of the fourth elastic element. The fourth elastic element can be a spring. The unlocking mechanism can be an unlocking button. Pressing the unlocking button causes the locking mechanism to move away from the adjustment slot 13, thus disengaging the locking mechanism from the adjustment slot 13.

[0081] Initially, the locking member is inserted into one of the adjustment slots 13, for example, into the lowest adjustment slot 13. After the locking member disengages from the adjustment slot 13, the headrest body 8 can move up and down relative to the headrest rod 1. When the headrest body 8 moves up and down until the locking member corresponds to another adjustment slot 13, the locking member is reset under the action of the fourth elastic member to be inserted into another adjustment slot 13. In this embodiment, the headrest body 8 can move up and down relative to the headrest rod 1 to adjust the height of the headrest body 8. During the adjustment of the height of the headrest body 8, the position of the headrest rod 1 remains unchanged to maintain the connection between the second air connector 31 and the first air connector 62, avoiding interruption of airflow or affecting the use effect of the pneumatic headrest due to headrest adjustment.
