Description

Technical Field

[0001] This utility model relates to the field of automotive seats, specifically to a vehicle seat electrical plug-in structure and seat. Background Technology

[0002] With the development of automotive intelligence, music headrests, as a feature to enhance passenger comfort, are gradually becoming standard equipment in high-end cars. Music headrests typically require an electrical plug to connect to the seat's internal audio system to transmit audio signals.

[0003] However, the existing electrical plug structure has the following problems: the existing electrical plug structure is inconvenient to plug and unplug. The traditional plug is used to connect the music headrest and the audio system. The traditional plug is located inside the seat back. The traditional plug cannot be disconnected automatically. The metal rod on the headrest cannot be completely pulled out from the seat back. Utility Model Content

[0004] This utility model aims to provide an electrical plug-in structure for a vehicle seat and a seat in general, so that users can easily and completely pull the metal rod of the headrest out of the seat. After being pulled out, the electrical plug-in structure automatically disconnects. When the metal rod is reinserted into the seat, the electrical plug-in structure automatically reconnects, thus solving the current problem that the metal rod on the headrest cannot be completely pulled out from the top of the seat back.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an electrical plug-in structure for a vehicle seat, comprising a plug unit and a socket unit; the plug unit includes a sheath for installation inside a metal rod and a first connecting terminal located inside the sheath; the socket unit includes a base and a second connecting terminal installed on the base, the base being equipped with a first spring clip for clamping the outer wall of the metal rod; the second connecting terminal can be inserted into the sheath and electrically connected to the first connecting terminal.

[0006] To achieve the above objectives, the present invention also adopts the following technical solution: a seat, including a seat back and a metal rod on the headrest, the metal rod having a cavity inside, and an opening at the bottom of the metal rod communicating with the cavity, and also including a vehicle seat electrical plug-in structure; a plug unit is installed inside the metal rod, and a socket unit is installed on the seat back.

[0007] The principle and advantages of this patented solution are as follows: The metal rod of the headrest is inserted into the seat back, the plug unit moves downward with the metal rod, the plug unit and the socket unit cooperate with each other, the second connecting terminal is inserted into the sheath inside the metal rod, and the first connecting terminal and the second connecting terminal contact each other, thereby realizing electrical connection. At the same time, the metal rod enters the inside of the first spring, the first spring is located on the outside of the metal rod, the first spring clamps the metal rod, the metal rod and the seat body are tightly connected, the plug unit and the socket unit are tightly connected, the plug unit and the socket unit are not easy to separate, and signal transmission interruption is avoided.

[0008] When the metal rod needs to be pulled upwards from the seat back, it moves upwards, overcomes the clamping of the first spring, and disengages from it. The metal rod then moves the plug unit upwards along with it, separating the plug unit from the socket unit, and separating the first and second connecting terminals. This disconnects the electrical connection and automatically disconnects the vehicle seat's electrical plug-in structure. The vehicle seat's electrical plug-in structure does not affect the metal rod's removal from the seat back, solving the current problem that the metal rod on the headrest cannot be completely removed from the top of the seat.

[0009] In summary, this patented solution allows users to easily and completely remove the metal rod of the headrest from the seat. After removal, the electrical plug-in structure automatically disconnects, and when the metal rod is reinserted into the seat, the electrical plug-in structure automatically reconnects.

[0010] The technical solution of this patent has the following effects: 1. Improved user experience: Through the quick-plug design, the plug unit and socket unit are automatically connected and disconnected when the metal rod is plugged in or out, making operation simple and improving user satisfaction. 2. Enhanced connection reliability: The first spring design ensures a stable connection between the metal rod and the socket unit, thereby ensuring a tight connection between the plug unit and the socket unit and avoiding signal transmission interruption.

[0011] Preferably, as an improvement, it also includes a mounting bracket for fixing to the seat back, the mounting bracket having a through hole for inserting a metal rod, and the socket unit being installed in the through hole of the mounting bracket.

[0012] Therefore, the metal rod is inserted downward into the seat back and into the through hole of the mounting base. Since the socket unit is installed in the through hole of the mounting base, after the metal rod is inserted into the through hole of the mounting base, the second connecting terminal on the socket unit enters the metal rod and makes an electrical connection with the first connecting terminal inside the sheath.

[0013] Preferably, as an improvement, a spring clip engagement mechanism is provided between the base and the fixed base; the base can be moved downward from the bottom of the fixed base through the through hole.

[0014] The spring-loaded snap-fit ​​mechanism enables a detachable connection between the seat and the fixed seat, allowing for automatic and stable connection and separation. Thus, when the metal rod is removed from the seat back, the seat and fixed seat are connected via the spring-loaded snap-fit ​​mechanism, preventing the socket unit from separating from the fixed seat. The socket unit remains stably positioned within the through-hole of the fixed seat and will not fall from the bottom. When the metal rod is inserted into the seat back, it moves downwards into the through-hole of the fixed seat. The first spring clip clamps the metal rod, and the first and second connecting terminals are electrically connected. Since the headrest, located on the seat back, requires height adjustment, after the metal rod moves downwards into the through-hole of the fixed seat, further downward pushing of the metal rod to lower the headrest creates a downward thrust on the socket unit. The socket unit overcomes the clamping force of the spring-loaded snap-fit ​​mechanism, separating from the fixed seat and moving downwards with the metal rod without obstructing its downward movement. Meanwhile, as the metal rod moves downward, the first spring clip is held in place on the outer wall of the metal rod, and the socket unit will not detach from the metal rod.

[0015] When the metal rod is pulled upward from the seat back, the metal rod drives the socket unit from the bottom of the fixed seat into the through hole of the fixed seat. The spring clip engagement mechanism then engages the socket unit and the fixed seat. Then, as the metal rod continues to move upward, the metal rod and the socket unit separate, the socket unit and the plug unit separate, and the socket unit remains fixed in the through hole of the fixed seat.

[0016] Preferably, as an improvement, the spring clip engaging mechanism includes a second spring clip installed on the inner wall of the through hole and a spring clip groove provided on the base; when the base is located in the through hole, the second spring clip is engaged in the spring clip groove.

[0017] Thus, the socket unit is located within the through hole of the mounting base, and the second spring clip is engaged in the spring clip slot, thereby securing the socket unit within the through hole of the mounting base and preventing it from falling off. When the metal rod moves the socket unit downwards, the spring clip slot and the second spring clip slide relative to each other, and the inner wall of the spring clip slot presses against the second spring clip, forcing it to move closer to the inner wall of the through hole. The second spring clip moves out of the spring clip slot, the socket unit and the mounting base disengage, and the socket unit detaches from the mounting base as the metal rod moves downwards.

[0018] Preferably, as an improvement, the inside of the through hole is provided with a first abutting surface, and the seat body is provided with a second abutting surface; when the seat body is located in the through hole, the first abutting surface and the second abutting surface abut against each other.

[0019] Therefore, when the metal rod is pulled out of the seat back, the first and second abutting surfaces abut against each other, thereby limiting the seat body and confining it in the fixed seat. After the metal rod is pulled out of the seat back, the socket unit remains in the fixed seat, preventing the metal rod from pulling the socket unit out with it.

[0020] Preferably, as an improvement, the seat body is provided with spring space for accommodating the first spring pieces, and multiple spring spacers are distributed around the circumference of the seat body. Thus, multiple first spring pieces surround the seat body, and the metal rod is inserted into the seat back. The multiple first spring pieces surround the metal rod, clamping it and ensuring the stability of the clamping of the metal rod by the first spring pieces.

[0021] Preferably, as an improvement, the spring slot is located on the side wall of the spring space.

[0022] Preferably, as an improvement, both the first connecting terminal and / or the second connecting terminal are magnetic terminals. This allows the first and second connecting terminals to attract each other magnetically, which improves the connection stability between them.

[0023] Preferably, as an improvement, the outer wall of the metal rod is provided with a slot for engaging the first spring clip. Thus, the first spring clip engages in the slot on the outer wall of the metal rod, and the engagement between the slot and the engaging end of the first spring clip improves the stability of the engagement between the first spring clip and the metal rod.

[0033] The following detailed description illustrates the specific implementation methods:

[0034] The reference numerals in the accompanying drawings include: 1. Fixing base; 2. Metal rod; 3. Base body; 4. Spring slot; 5. First spring; 6. Snap-fit ​​end; 7. Second connecting terminal; 8. Second wire harness; 9. Sheath; 10. First wire harness; 11. First connecting terminal; 12. Spring space sidewall; 13. Second spring; 14. First abutment surface; 15. Through hole; 16. Second abutment surface.

[0035] The basic implementation examples are as follows: Figures 1-8 As shown: This embodiment discloses an electrical plug-in structure for a vehicle seat, including a plug unit, a socket unit, and a mounting base 1. The plug unit and the socket unit are detachably connected. In this embodiment, the vehicle seat electrical plug-in structure is installed on a car seat, with the socket unit and mounting base 1 installed inside the seat back, and the plug unit installed inside the metal rod 2 of the headrest. When the metal rod 2 is inserted into the seat back, the socket unit and the plug unit cooperate to form an electrical connection, thereby realizing the electrical connection between the electrical components inside the headrest and the electrical components inside the seat.

[0036] Combination Figure 6 and Figure 7 As shown, the metal rod 2 of the headrest is tubular, with an opening at its bottom that communicates with the internal cavity of the metal rod 2. The plug unit in this embodiment includes a sheath 9 for installation inside the cavity of the metal rod 2 and a first connecting terminal 11 located within the sheath 9. The sheath 9 and the internal cavity of the metal rod 2 can be fixed by adhesive bonding (adhesive is applied between the outer wall of the sheath 9 and the interior of the metal rod 2), snap-fit ​​fixing, or screw fixing (screws are connected between the side wall of the metal rod 2 and the outer wall of the sheath 9). In this embodiment, the sheath 9 is made of insulating engineering plastic. In this embodiment, the first connecting terminal 11 is a magnetic terminal (4-pin). A first wire harness 10 is connected to the end of the sheath 9. The first wire harness 10 and the first connecting terminal 11 are electrically connected. The first wire harness 10 is located within the metal rod 2, and the end of the first wire harness 10 furthest from the sheath 9 is connected to an electrical component of the headrest.

[0037] Combination Figure 2As shown, the socket unit in this embodiment includes a base 3 and a second connecting terminal 7 mounted on the top of the base 3. A second wiring harness 8 is connected to the bottom of the base 3, and the second wiring harness 8 and the second connecting terminal 7 are electrically connected. The end of the second wiring harness 8 away from the base 3 is connected to an electrical component on the seat. In this embodiment, the base 3 is made of insulating engineering plastic. The second connecting terminal 7 is located on the top of the base 3 and is also a 4-pin type terminal. The second connecting terminal 7 can also be a magnetic terminal, or it can have a metal part (e.g., an iron part) that can be attracted by the first connecting terminal 11. In this way, the second connecting terminal 7 and the first connecting terminal 11 can cooperate and attract each other, achieving a stable electrical connection between the second connecting terminal 7 and the first connecting terminal 11. Of course, in other embodiments, the second connecting terminal 7 can also be a magnetic terminal, and the first connecting terminal 11 can be non-magnetic. The first connecting terminal 11 can have a metal part (e.g., an iron part) that can be attracted by the second connecting terminal 7, thereby also achieving attraction between the second connecting terminal 7 and the first connecting terminal 11.

[0038] In this embodiment, the base 3 is equipped with two first metal spring clips 5 for clamping the outer wall of the metal rod 2. The first spring clips 5 can be made of steel. The base 3 in this embodiment has spring clip spaces on both sides, and the first spring clips 5 are located in the spring clip spaces. The first spring clips 5 can be fixed to the side wall 12 of the spring clip space by a shaft. The top of the first spring clip 5 is a snap-fit ​​end 6, which is arc-shaped. There is a gap between the snap-fit ​​end 6 and the second connecting terminal 7, which can accommodate the side wall of the metal rod 2. When the first connecting terminal 11 and the second connecting terminal 7 are engaged, the second connecting terminal 7 is inserted into the sheath 9, and the metal rod 2 is fitted outside the second connecting terminal 7. The outer wall of the metal rod 2 is clamped by the snap-fit ​​end 6 of the first spring clip 5. To improve the stability of the clamping of the outer wall of the metal rod 2 by the snap-fit ​​end 6 of the first spring clip 5, the outer wall of the metal rod 2 is provided with a groove (not shown in the figure). The groove can be annular and coaxial with the metal rod. The snap-fit ​​end 6 is engaged in the groove, thereby making the clamping of the metal rod 2 by the first spring clip 5 more stable.

[0039] The fixing base 1 in this embodiment is specifically as follows: Figure 3 and Figure 4 As shown, in this embodiment, the fixing seat 1 is specifically fixed (e.g., welded, fixed with screws, or snap-fitted) to the seat frame of the seat back. The fixing seat 1 is provided with a through hole 15 for inserting the metal rod 2, and the through hole 15 passes through the top and bottom ends of the fixing seat 1. Figure 5As shown, the socket unit is installed from the bottom of the fixing base 1 into the through hole 15 of the fixing base 1. In this embodiment, a spring clip engaging mechanism is provided between the base 3 and the fixing base 1. The spring clip engaging mechanism includes a second spring clip 13 installed on the inner wall of the through hole 15 and a spring clip groove 4 provided on the base 3. The second spring clip 13 is also made of steel, similar to the structure of the first spring clip 5 and the arrangement of the first spring clip 5 and the base 3. Two spring clip mounting grooves are provided on the inner wall of the through hole 15. The second spring clip 13 is engaged in the spring clip mounting groove. The second spring clip 13 has a engaging part for engaging into the spring clip groove 4, similar to the engaging end 6 on the first spring clip 5. The engaging part is bent and protrudes from the second spring clip 13. Thus, when the base 3 is located in the through hole 15, the engaging part of the second spring clip 13 is engaged in the spring clip groove 4, thereby making the socket unit stably located in the fixing base 1, and the socket unit will not fall out of the fixing base 1 naturally. When the socket unit is pushed downwards, the base 3 moves downwards relative to the fixed base 1, thereby forcing the snap-fit ​​part of the second spring 13 to retract (move towards the inner wall of the through hole 15) and leave the spring slot 4. The second spring 13 does not affect the downward movement of the socket unit, and the socket unit can be separated from the fixed base 1, and the socket unit moves out from the bottom of the fixed base 1.

[0040] Combination Figure 3 As shown, the interior of the through hole 15 is provided with a first abutting surface 14, which faces the bottom end of the fixed base 1, and is combined with... Figure 2 As shown, the top of the base 3 is provided with a second abutment surface 16. When the socket unit is inserted into the through hole 15 from the bottom of the fixed base 1, the socket unit can no longer move upward relative to the fixed base 1 when the first abutment surface 14 and the second abutment surface 16 abut against each other, thus indicating that the socket unit is installed in place.

[0041] As can be seen from the above description, this embodiment not only discloses a vehicle seat electrical plug-in structure, but also discloses a seat, including a seat back, a metal rod 2 on the headrest, and a vehicle seat electrical plug-in structure; wherein the plug unit is installed inside the metal rod 2, and the socket unit is installed inside the seat back.

[0042] The specific implementation process is as follows: Initially, the socket unit is inserted into the through hole 15 from the bottom of the fixed base 1, and the snap-fit ​​part of the second spring 13 is snapped into the spring slot 4, and the socket unit is stably located in the fixed base 1. The metal rod 2 of the headrest is inserted into the seat back. The metal rod 2 moves downward in the seat back and enters the through hole 15 of the fixing seat 1 from the top of the fixing seat 1. The second connecting terminal 7 on the socket unit is inserted into the metal rod 2. The second connecting unit is inserted into the sheath 9 inside the metal rod 2. The first connecting terminal 11 and the second connecting terminal 7 contact each other, thereby realizing electrical connection. At the same time, the metal rod 2 is fitted outside the second connecting terminal 7. The side wall of the metal rod 2 enters between the first spring 5 and the second connecting terminal 7. The side wall of the metal rod 2 is located inside the first spring 5. The first spring 5 is located outside the metal rod 2. The snap-fit ​​end 6 of the first spring 5 is snapped into the slot of the metal rod 2. The snap-fit ​​end 6 of the first spring 5 clamps the metal rod 2. The metal rod 2 and the seat body 3 are tightly connected. The plug unit and the socket unit are tightly connected to avoid signal transmission interruption.

[0043] When it is necessary to continue inserting the metal rod 2 downwards to lower the headrest height, the metal rod 2 continues to move downwards, pushing the socket unit downwards. The spring slot 4 applies pressure to the locking part of the second spring piece 13, causing the locking part of the second spring piece 13 to retract. The locking part of the second spring piece 13 moves towards the inner wall of the through hole 15 of the fixing seat 1, and the locking part of the second spring piece 13 moves out of the spring slot 4. The socket unit and the fixing seat 1 are released from the locking. At this time, the socket unit separates from the fixing seat 1, and the socket unit located on the end of the metal rod 2 moves downwards along with the metal rod 2. The socket unit does not obstruct the downward movement of the metal rod 2, and the headrest height can be lowered, thereby realizing the downward adjustment of the headrest height. Figure 9 As shown, after the metal rod 2 moves downward, the socket unit remains at the end of the metal rod 2, and the socket unit and the plug unit maintain an electrical connection.

[0044] When the headrest height needs to be adjusted upwards, the metal rod 2 moves upwards, and the socket unit, located at the end of the metal rod 2, moves upwards along with the metal rod 2. The socket unit and the plug unit remain electrically connected.

[0045] When it is necessary to pull the metal rod 2 upward from the seat back, the headrest is pulled upward, causing the headrest to move the metal rod 2 upward. The metal rod 2 then moves the socket unit upward, and the socket unit enters the through hole 15 from the bottom of the fixing seat 1. The snap-fit ​​part of the second spring 13 snaps back into the spring slot 4. At the same time, the first abutment surface 14 and the second abutment surface 16 abut against each other, and the socket unit is blocked by the fixing seat 1, so the socket unit no longer moves upward with the metal rod 2. However, the metal rod 2 continues to move upward. The metal rod 2 overcomes the clamping of the first spring 5 and disengages from the first spring 5. The plug unit and the socket unit separate, and the first connecting terminal 11 and the second connecting terminal 7 separate, thereby realizing the electrical disconnection. This achieves the automatic disconnection of the vehicle seat electrical plug-in structure, and the vehicle seat electrical plug-in structure will not affect the metal rod 2 being pulled out from the seat back. This solves the current problem that the metal rod 2 on the headrest cannot be completely pulled out from the top of the seat.

[0046] In summary, through this embodiment, when the metal rod 2 is inserted into the seat back, the socket unit and the plug unit automatically connect. Furthermore, as the metal rod 2 moves vertically downwards, the socket unit is fixed to the end of the metal rod 2 and automatically separates from the fixing seat 1. The socket unit moves with the metal rod 2 without affecting its vertical downward movement. Subsequently, during headrest height adjustment, the socket unit and the plug unit remain connected.

[0047] When the metal rod 2 moves vertically upward and is pulled out, the socket unit automatically enters the fixing seat 1 and is fixed. The socket unit and the metal rod 2 automatically separate, and the socket unit and the plug unit automatically disconnect, so as not to affect the metal rod 2 from being pulled out of the seat back.

[0048] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model.
