Description

A connector, a connector device, a seat, and a vehicle

[0001] This application claims priority to Chinese Patent Application No. 202420736915.8, filed on April 8, 2024, entitled “A Connecting Component, Connecting Device, Seat and Vehicle”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of electrical connector technology, and more particularly to a connector component, connector device, seat, and vehicle. Background Technology

[0003] Car seat audio headrests are becoming increasingly popular, with many models, especially new energy vehicles, featuring driver's side audio headrests for functions such as private calls, navigation, and private music playback. Because the audio system needs power and sound quality must be maintained, most seat solutions involve running the audio wiring harness from inside the headrest rod and connecting it to the vehicle's power supply via an internal seat wiring harness. To prevent users from accidentally breaking the wiring harness when removing the headrest, most are designed to be non-removable or use concealed locks to prevent removal.

[0004] Compared to traditional vehicles, new energy vehicles not only emphasize the driving experience but also focus on creating versatile interior spaces, resembling home environments and camping experiences. The non-removable speaker headrests restrict the folding or reclining of the seats, significantly limiting the creation of these aforementioned spatial scenarios.

[0005] Application content

[0006] This application provides a connector, connector device, seat, and vehicle, which aims to achieve pluggable functionality and stable power supply for the audio headrest.

[0007] This application provides a connector in a first aspect, the connector comprising:

[0008] A support member having a sliding channel with a first opening, and a limiting protrusion provided on the inner wall of the sliding channel;

[0009] A first connector assembly is installed within the sliding channel and is movable along the sliding channel;

[0010] A limiting component, which is located within the sliding channel and is capable of sliding relative to the support member along the sliding channel;

[0011] The limiting component can abut against the limiting protrusion along a first direction, so that the first insertion component is fixed in a first position within the sliding channel.

[0012] In this application, the area between the limiting protrusion and the first opening is defined as the limiting area. When the limiting protrusion restricts the first connector component to any position within the limiting area via the limiting component, the first connector component can be completely located within the sliding channel. At this time, the first connector component is positioned close to the first opening, which facilitates cooperation with the second connector component and reduces the risk of damage to parts of the first connector component that are exposed to the outside.

[0013] Alternatively, when the limiting protrusion restricts the first connector component to any position in the limiting area by the limiting component, a portion of the first connector component may be exposed outside the sliding channel through the first opening to facilitate cooperation with the second connector component.

[0014] In one possible design, along the first direction, the support member has a top and a bottom, the top being provided with a first blocking portion, and the bottom being provided with a second opening and a second blocking portion, the second opening being disposed opposite to the first opening, and the second blocking portion being disposed opposite to the first blocking portion.

[0015] In this application, by setting a first blocking part and a second blocking part, the first connector assembly can be prevented from disengaging in both directions, thus ensuring the stability of the connector device.

[0016] In one possible design, the limiting component includes an elastic element and at least two limiting elements. Along a second direction, the two ends of the elastic element are respectively connected to the two limiting elements. The limiting elements are in a compressed state so that the limiting elements abut against the inner wall of the sliding channel.

[0017] In this application, two limiting members abut against the inner wall of the sliding channel and compress the elastic member, so that the elastic member is in a compressed state and provides a thrust to the two limiting members, so as to maintain the abutment between the limiting members and the inner wall of the sliding channel and keep them in any position.

[0018] In one possible design, the limiting assembly further includes a housing, the elastic element and the two limiting elements are mounted on the housing, and at least a portion of the two limiting elements can extend out of the housing;

[0019] One of the outer sidewall of the housing and the inner sidewall of the sliding channel is provided with a slider, and the other is provided with a sliding groove, wherein the slider and the sliding groove are slidably engaged.

[0020] In this application, by setting the slider and the slide groove to slide together, the movement trajectory of the limiting component is limited, thereby ensuring the stability of the first connector component moving within the sliding channel.

[0021] In a second aspect, this application provides a connector device, the connector device including the connector member described above, and further including a second connector assembly, the second connector assembly being plugged into and engaged with the first connector assembly, and the second connector assembly being electrically connected to the first connector assembly.

[0022] In this application, the first connector is electrically connected to the vehicle power supply via the backrest wiring harness, and the second connector is electrically connected to the speaker in the headrest via the speaker wiring harness. When the first connector and the second connector are electrically connected, the speaker wiring harness and the backrest wiring harness can be electrically connected, and the vehicle power supply connected to the speaker wiring harness is powered by the vehicle power supply connected to the backrest wiring harness.

[0023] The first and second connector components are detachably connected. Specifically, at least a portion of the second connector component can extend through a first opening into a sliding channel to engage with the first connector component, achieving both electrical and mechanical connection between the two components. When the headrest is removed from the backrest, the audio wiring harness and backrest wiring harness can be disconnected by disassembling the first and second connector components, preventing the wiring harness from being broken during headrest removal. Removing the headrest allows the seat to fold in half and recline, catering to various user scenarios and improving the user experience.

[0024] Furthermore, when the first connector assembly is installed in the sliding channel, it can also slide relative to the support member along the sliding channel. That is, when the first connector assembly and the second connector assembly are in a mating state, they can slide within the sliding channel. When the headrest angle needs to be adjusted, that is, when the headrest rotates relative to the backrest, the second connector assembly installed in the headrest moves with the rotation of the headrest. The second connector assembly drives the first connector assembly connected to it to slide within the sliding channel. In other words, when the headrest rotates, the first connector assembly and the second connector assembly can move synchronously and remain connected to maintain normal power supply when adjusting the headrest angle.

[0025] In one possible design, the first connector assembly includes a first connector and a first conductive element, the first conductive element being mounted on the outer side wall of the first connector, and the first connector assembly having a limiting portion.

[0026] The second connector assembly includes a second connector and a second conductive element. The second connector is provided with a receiving cavity, and the second conductive element is installed in the receiving cavity. A limiting part is provided in the receiving cavity. The second connector assembly is movable relative to the support member so that the connector device has at least a first state or a second state.

[0027] In the first state, a portion of the structure of the second connector assembly can extend into the sliding channel, so that at least a portion of the first connector assembly can extend into the receiving cavity, the first conductive member and the second conductive member are electrically connected, and the limiting portion cooperates with the limited portion; in the second state, the first conductive member and the second conductive member are de-connected, and the limiting portion is de-cooperative with the limited portion.

[0028] In this application, when the second connector extends into the sliding channel through the first opening, at least a portion of the structure of the first connector can extend into the receiving cavity, so that the limiting part cooperates with the limited part, and the first conductive element and the second conductive element are electrically connected, thereby realizing the simultaneous electrical connection between the first connector and the second connector.

[0029] When the first connector assembly disengages from the receiving cavity, the limiting part and the limited part are disengaged, and the first conductive element and the second conductive element are disconnected from each other. At this time, the second connector assembly disengages from the sliding channel, so that the first connector assembly and the second connector assembly are completely separated.

[0030] This application ensures the stability of the electrical connection between the first conductive element and the second conductive element by cooperating with the limiting part and the limited part, so that when the first and second connector components in the cooperating state move within the sliding channel.

[0031] In one possible design, the resistance to the first connector assembly disengaging from the second connector assembly along the first direction is a first force value F1.

[0032] Along the first direction, after the first connector component and the second connector component are engaged, the resistance of the limiting protrusion encountered by the two components when they move to below the limiting protrusion is the second force value F2.

[0033] F1 and F2 satisfy the condition: F2 > F1.

[0034] In this application, this embodiment sets F2 > F1 so that the external force applied to the first connector component and the second connector component when they cooperate will not cause the limiting component to move downward to below the limiting protrusion, so that the first connector component completes the cooperation with the second connector component 13 within the limiting area, which facilitates the cooperation between the first connector component and the second connector component.

[0035] In one possible design, the resistance to the first connector assembly disengaging from the second connector assembly along the first direction is a first force value F1.

[0036] During the sliding process of the limiting component along the sliding channel, the resistance of the inner wall of the sliding channel to the limiting component is a third force value F3; F1 and F3 satisfy: F1 > F3.

[0037] In this application, by setting F1 > F3, when the first connector component and the second connector component are in a mating state, pressing the second connector component will cause the first connector component and the limiting component to move synchronously within the sliding channel, thereby adjusting the headrest position and preventing the first connector component and the second connector component from disengaging, thus improving the reliability of the electrical connection between the first conductive component and the second conductive component when adjusting the headrest position.

[0038] In one possible design, the resistance to the first connector assembly disengaging from the second connector assembly along the first direction is a first force value F1.

[0039] Along the first direction, after the first connector component and the second connector component are engaged, the resistance of the limiting protrusion encountered by the two components when they move above the limiting protrusion is the fourth force value F4.

[0040] F1 and F4 satisfy the condition: F1 > F4.

[0041] In this application, by setting F1>F4, when the user applies an external force of the fourth force value F4 to make the first connector component and the second connector component move upward past the limit protrusion in the mating state, the fourth force value F4 will not cause the first connector component and the second connector component to disengage.

[0042] This application provides a connector in a third aspect, the connector comprising:

[0043] Support member, wherein the support member has a sliding channel;

[0044] A first connector assembly is installed in the sliding channel and is movable in a first direction. The first connector assembly includes a first connector and a first conductive element. The first conductive element is installed on the outer side wall of the first connector. The first connector assembly is provided with a limiting portion.

[0045] The second connector assembly includes a second connector and a second conductive element. The second connector is provided with a receiving cavity, and the second conductive element is installed in the receiving cavity. A limiting part is provided in the receiving cavity. The second connector assembly is movable relative to the support member so that the connector device has at least a first state or a second state.

[0046] In the first state, a portion of the structure of the second connector assembly can extend into the sliding channel, so that at least a portion of the first connector assembly can extend into the receiving cavity, the first conductive member and the second conductive member are electrically connected, and the limiting portion cooperates with the limited portion; in the second state, the first conductive member and the second conductive member are de-connected, and the limiting portion is de-cooperative with the limited portion.

[0047] In this application, when the second connector extends into the sliding channel through the first opening, at least a portion of the structure of the first connector can extend into the receiving cavity, so that the limiting part cooperates with the limited part, and the first conductive element and the second conductive element are electrically connected, thereby realizing the simultaneous electrical connection between the first connector and the second connector.

[0048] When the first connector assembly disengages from the receiving cavity, the limiting part and the limited part are disengaged, and the first conductive element and the second conductive element are disconnected from each other. At this time, the second connector assembly disengages from the sliding channel, so that the first connector assembly and the second connector assembly are completely separated.

[0049] This application ensures the stability of the electrical connection between the first conductive element and the second conductive element by cooperating with the limiting part and the limited part, so that when the first and second connector components in the cooperating state move within the sliding channel.

[0050] In one possible design, along the first direction, the outer side wall of the first connector assembly is provided with at least two spaced protrusions, the at least two of the protrusions forming the limiting portion, the limiting portion being a structure that protrudes toward the center of the receiving cavity.

[0051] In this application, the limiting part is formed by at least two protrusions surrounding each other along a first direction, and the limited part is a structure that protrudes towards the center of the receiving cavity. When the limiting part and the limited part are engaged, the limited part is locked between the two protrusions. The contact between the limited part and the opposite end faces of the protrusions restricts the limited part from disengaging from the limiting part, thereby reducing the risk of the first connector assembly and the second connector assembly falling off.

[0052] At least one of the protrusion and the limited portion is elastic, so that during the process of the first connector assembly and the second connector assembly engaging or disengaging, at least one of the protrusion and the limited portion can be squeezed, so that the limited portion can engage or disengage with the limiting portion.

[0053] In one possible design, the protrusion is disposed on the first conductive member, and the second conductive member is disposed on at least one side of the limited portion along the first direction.

[0054] In this application, the first conductive element may be a conductive spring, the insulating element may be a plastic element, and the protrusion is formed by bending a portion of the structure of the first conductive element. When the first connector assembly and the second connector assembly are engaged, the protrusion abuts against a portion of the structure of the second conductive element corresponding to the second direction, so as to achieve electrical connection between the first conductive element and the second conductive element.

[0055] This application provides a protrusion on the first conductive element and provides second conductive elements on both sides of the limited portion along the first direction, so that the protrusion can abut against the second conductive element, thereby achieving electrical connection between the first and second conductive elements and limiting the first and second connector components, thus realizing the snap-fit ​​engagement between the first and second connector components.

[0056] In one possible design, the second connector assembly also includes an insulating element;

[0057] The inner wall of the receiving cavity is provided with a slot, and the insulating component is installed in the slot;

[0058] The second conductive element is mounted on the insulating element.

[0059] In this application, to ensure the structural strength of the second connector, the second connector is made of metal. Therefore, by setting an insulating component, the second connector is isolated from the insulating component, which achieves the effect of insulation and protection.

[0060] The insulating component is provided with a snap-fit ​​groove, and the second conductive component is fixed to the insulating component by snapping into the snap-fit ​​groove. Alternatively, the second conductive component can be fixed to the insulating component by adhesive bonding. Furthermore, other methods can be used to fix the second conductive component to the insulating component, which are not limited herein.

[0061] In one possible design, the limited portion is disposed on the insulating member, and along the first direction, the second conductive member is disposed on at least one side of the limited portion.

[0062] In this application, the first conductive element may be a conductive spring, the insulating element may be a plastic element, the protrusion is formed by bending a portion of the first conductive element, and the limited portion is formed by a portion of the insulating element. When the first connector assembly and the second connector assembly are engaged, the protrusion abuts against a portion of the second conductive element corresponding to the second direction, thereby achieving an electrical connection between the first conductive element and the second conductive element.

[0063] This application provides a protrusion on the first conductive member, a limited portion on the insulating member, and second conductive members on both sides of the limited portion along the first direction, so that the protrusion can abut against the second conductive member. This achieves electrical connection between the first and second conductive members while also limiting the first and second connector components, thus enabling the first and second connector components to engage.

[0064] In one possible design, the protrusion is disposed on the first conductive element, and the limited portion is disposed on the second conductive element.

[0065] In this application, the first conductive element and the second conductive element can be conductive springs. The protrusion is formed by bending a portion of the structure of the first conductive element, and the limited portion is formed by bending a portion of the structure of the second conductive element. When the first connector assembly and the second connector assembly are engaged, at least one of the limited portion and the protrusion remains in contact with the corresponding portion of the conductive structure along the second direction, thereby achieving electrical connection between the first conductive element and the second conductive element.

[0066] For example, in one scenario, the limited portion abuts against the first conductive element corresponding to the second direction, while the protrusion does not abut against the second conductive element corresponding to the second direction. In this case, by electrically connecting the limited portion to the first conductive element, an electrical connection between one conductive element and the second conductive element can be achieved. It should be noted that even if the protrusion does not abut against the second conductive element, but the distance between the protrusion and the second conductive element along the second direction X is less than the thickness of the limited portion along the second direction, the protrusion still functions as a limiter on the limited portion.

[0067] In another embodiment, the protrusion abuts against the second electrical component corresponding to the second direction, while the limited portion does not abut against the first conductive component corresponding to the second direction. In this case, electrical connection between the protrusion and the second electrical component allows for electrical connection between the two conductive components. It should be noted that even if the limited portion does not abut against the first conductive component, but the distance between the limited portion and the first conductive component along the second direction is less than the thickness of the protrusion along the second direction, the protrusion still functions as a limiter on the limited portion.

[0068] In another embodiment, the protrusion abuts against the second electrical component corresponding to the second direction, and the limited portion abuts against the first conductive component corresponding to the second direction. In this case, the protrusion is electrically connected to the second electrical component, and the limited portion is electrically connected to the first conductive component, thereby achieving electrical connection between one conductive component and the second conductive component.

[0069] This application provides a protrusion on the first conductive element and a limiting part on the second conductive element, thereby enabling the first conductive element and the second conductive element to contact and form an electrical connection, while also limiting the first and second connector components, thus achieving a snap-fit ​​engagement between the first and second connector components.

[0070] In one possible design, the protrusion is disposed on the first connector, and along the first direction, the first conductive element is disposed between the two protrusions;

[0071] The limiting portion is disposed on the second conductive element.

[0072] In this application, the second conductive element may be a conductive spring, with the protrusion formed by the outward protrusion of a portion of the first conductive element and the limiting portion formed by bending a portion of the second conductive element. When the first connector assembly and the second connector assembly are engaged, the limiting portion abuts against a portion of the first conductive element corresponding to the second direction, thereby achieving an electrical connection between the first conductive element and the second conductive element.

[0073] This application provides a protrusion in the first connector and a first conductive element between the protrusions, and a limiting part in the second conductive element, so that the limiting part abuts against the first conductive element. This achieves electrical connection between the first and second conductive elements, while also limiting the first and second connector components, thus enabling the first and second connector components to engage.

[0074] This application provides a seat in a fourth aspect, the seat comprising:

[0075] Backrest;

[0076] A headrest, which is detachably mounted on top of the backrest and can be adjusted in position relative to the backrest;

[0077] A connector, wherein the connector is the connector described above;

[0078] The support member is installed on the backrest, and the second connector is installed on the headrest.

[0079] In this application, by designing the above-mentioned connector, the headrest and backrest can be detachably connected, and the power supply is ensured when the headrest is reinstalled with the backrest and when the position is adjusted up and down.

[0080] In one possible design, along the first direction, after the first connector component and the second connector component are engaged, the resistance of the limiting protrusion encountered by both components when they move to below the limiting protrusion is the second force value F2.

[0081] Along the first direction, the resistance to the support member disengaging from the backrest is the fifth force value F5;

[0082] F2 and F5 satisfy the condition: F5 > F2.

[0083] In this application, when the user applies an external force to the plug-in device to make the limiting component move upward past the limiting protrusion, the external force is less than the fifth force value F5 for the support to detach from the backrest, thus preventing the plug-in device from detaching from the backrest when it is pulled out.

[0084] This application provides a vehicle in a fifth aspect, the vehicle comprising:

[0085] Vehicle body;

[0086] The seat is the seat described above, and the seat is installed on the vehicle body.

[0087] In this application, by setting up a detachable headrest, the seat can be folded in half or reclined, which greatly enhances the experience of creating versatile interior spaces, home scenes, and camping experiences. Attached Figure Description

Detailed Implementation

[0114] With the advent of the electrification era, the configuration of vehicle electrical systems is becoming increasingly sophisticated, and headrests with audio speakers are becoming more common. These headrests are connected to the vehicle's power supply via wiring harnesses, enabling functions such as playing calls, navigation announcements, and music from the headrest. However, in related technologies, the wiring harnesses connecting the headrests and the vehicle's power supply lack detachability, resulting in the headrests being non-removable or prone to breakage when attempting to remove them.

[0115] To address this, this embodiment provides a connector to solve the aforementioned technical problems. The possible structure of the connector is described in detail below with reference to the accompanying drawings.

[0116] Figure 1 shows a schematic diagram of part of the connector 1 structure. The connector 1 includes a support member 11, a first connector assembly 12, a second connector assembly 13, an audio wiring harness 2, and a backrest wiring harness 3. In the connector 1 provided in this application embodiment, when the first connector assembly 12 and the second connector assembly 13 are electrically connected, the audio wiring harness 2 and the backrest wiring harness 3 can be electrically connected. Since the vehicle power supply is connected to the backrest wiring harness 3, the vehicle power supply can supply power to the audio system (the audio system installed in the headrest).

[0117] The support member 11 and the first connector assembly 12 are mounted on the backrest, and the second connector assembly 13 is mounted on the headrest. Specifically, the support member 11 is a metal frame structure, a plastic bracket structure, etc. The support member 11 is mounted on the backrest (not shown in the figure) and has a first opening 112a that is connected to it. The speaker wiring harness 2 extends through the first opening 112a to connect with the speaker.

[0118] 112a can be formed in the first blocking part 112 along the first direction Y. The first blocking part 112 is the top structure of the support member 11. The first blocking part 112 is used to prevent the first plug-in assembly 12 from disengaging from the sliding channel 111. At the same time, it can prevent the second plug-in assembly 13 from taking the first plug-in assembly 13 out of the sliding channel 111, thereby realizing the disengagement of the first plug-in assembly 12 and the second plug-in assembly 13.

[0119] The support member 11 also has a sliding channel 111, in which the first connector 12 is installed so that the first connector 12 can slide along the sliding channel 111.

[0120] The support member 11 also has a second opening 113a, through which the first connector assembly 12 is electrically connected to the backrest wiring harness 3, which extends through the second opening 113a to be electrically connected to the vehicle power supply (not shown).

[0121] 113a can be formed in the second blocking part 113 along the first direction Y. The second blocking part 113 is the bottom structure of the support member 11. The second blocking part 113 is used to prevent the first connector assembly 12 from disengaging from the sliding channel 111.

[0122] The second connector 13 is electrically connected to the audio wiring harness 2 inside the headrest, and the audio wiring harness 2 is electrically connected to the headrest (the audio system installed inside the headrest). Therefore, when the first connector 12 and the second connector 13 are electrically connected, the audio wiring harness 2 and the backrest wiring harness 3 can be electrically connected, and the vehicle power supply connected to the audio wiring harness 2 is powered through the backrest wiring harness 3.

[0123] The first connector assembly 12 and the second connector assembly 13 can be detachably connected. Specifically, at least a portion of the second connector assembly 13 can extend through the first opening 112a into the sliding channel 111 to engage with the first connector assembly 12, achieving both electrical and mechanical connection between the second connector assembly 13 and the first connector assembly 12. Furthermore, when the headrest is removed from the backrest, the audio wiring harness 2 and the backrest wiring harness 3 can be disconnected by disassembling the first connector assembly 12 and the second connector assembly 13, preventing the wiring harness from being broken when the headrest is removed. Removing the headrest allows the seat to fold in half and recline, meeting various user needs and improving the user experience.

[0124] Furthermore, when the first connector assembly 12 is installed in the sliding channel 111, it can also slide relative to the support member 11 along the sliding channel 111. That is, when the first connector assembly 12 and the second connector assembly 13 are in a mating state, they can slide within the sliding channel 111. When the headrest angle needs to be adjusted, that is, when the headrest rotates relative to the backrest, the second connector assembly 13 installed in the headrest moves with the rotation of the headrest, and the second connector assembly 13 drives the first connector assembly 12 connected to it to slide within the sliding channel 111. That is, when the headrest rotates, the first connector assembly 12 and the second connector assembly 13 can move synchronously, and the two remain connected to maintain normal power supply when adjusting the headrest angle.

[0125] The following section will describe the specific structure of the detachable connection between the first connector assembly 12 and the second connector assembly 13.

[0126] It should be noted that, in the following text, the first direction refers to the direction in which the sliding channel 111 extends, and the second direction refers to the direction that is approximately perpendicular to the direction in which the sliding channel 111 extends.

[0127] Figure 2 shows a schematic diagram of the first connector assembly 12. The first connector assembly 12 includes a first connector 121 and a first conductive element 122. The first conductive element 122 is installed on the outer side wall of the first connector 121. When the first connector assembly 12 mates with the second connector assembly 13, the first conductive element 122 is used to conduct electricity with the second connector assembly 13. The second conductive element 122 is also used to electrically connect with the backrest wiring harness 3.

[0128] Along the first direction Y, the outer side wall of the first connector assembly 12 is provided with at least two spaced protrusions 122a, which together form a limiting portion 122d. When the first connector assembly 12 mates with the second connector assembly 13, the limiting portion 122d is used to limit the engagement with the second connector assembly 13.

[0129] Figure 3 shows a schematic diagram of the second connector assembly 13. The second connector assembly 13 includes a second connector 131, a second conductive element 132, and an insulating element 133 (the insulating element 133 is described in detail below). The second connector 131 is provided with a receiving cavity 131a, and the second conductive element 132 is installed in the receiving cavity 131a. When the first connector assembly 12 and the second connector assembly 13 are engaged, the second conductive element 132 can conduct electricity with the first connector assembly 12. The second conductive element 132 is also used for electrical connection with the audio wiring harness 2.

[0130] A limiting portion 132a is provided inside the receiving cavity 131a. Along the second direction X, the limiting portion 132a has a structure that protrudes toward the center of the receiving cavity 131a. When the first connector assembly 12 and the second connector assembly 13 are engaged, the limiting portion 132a is used to engage and limit the first connector assembly 12.

[0131] The connector 1 has at least a first state (cooperative state) and a second state (discooperative state). Figure 4 shows a schematic diagram of the first connector assembly 12 and the second connector assembly 13 in the cooperative state. Referring to Figures 1 and 4, in the first state, a portion of the structure of the second connector assembly 13 can extend into the sliding channel 111, allowing at least a portion of the first connector assembly 12 to extend into the receiving cavity 131a. At this time, the first conductive element 122 and the second conductive element 132 are electrically connected, and the limiting portion 122d cooperates with the limited portion 132a.

[0132] Figure 5 shows a schematic diagram of the first connector assembly 12 and the second connector assembly 13 in a disengaged state. In the second state, the first connector assembly 12 can disengage from the receiving cavity 131a. At this time, the first conductive element 122 and the second conductive element 132 are de-energized, and the limiting part 122d is de-energized from the limited part 132a. The second connector assembly 13 can further disengage from the sliding channel 111.

[0133] In this embodiment, when the second connector 13 extends into the sliding channel 111 through the first opening 112a, at least a portion of the structure of the first connector 12 can extend into the receiving cavity 131a, causing the limiting part 122d to engage with the limited part 132a. The first conductive element 122 and the second conductive element 132 are electrically connected, achieving simultaneous engagement and electrical connection between the first connector 12 and the second connector 13. This enables electrical connection between the audio wiring harness 2 and the backrest wiring harness 3, and consequently, electrical connection between the headrest and the vehicle's power supply. When the headrest angle is adjusted, the engagement of the limiting part 122d and the limited part 132a ensures the stability of the electrical connection between the first conductive element 122 and the second conductive element 132 as the first connector 12 and the second connector 13 move within the sliding channel 111. This ensures a reliable electrical connection between the headrest and the vehicle's power supply even when the headrest angle is adjusted.

[0134] When the first connector assembly 12 disengages from the receiving cavity 131a, the limiting part 122d disengages from the limited part 132a, and the first conductive member 122 and the second conductive member 132 are disconnected from each other. At this time, the second connector assembly 13 disengages from the sliding channel 111, thereby disconnecting the second connector assembly connected to the headrest from the first connector assembly connected to the backrest, and thus making the headrest detachable.

[0135] Specifically, the limiting part 122d is formed by at least two protrusions 122a surrounding each other along the first direction Y, and the limited part 132a is a structure that protrudes towards the center of the receiving cavity 131a. When the limiting part 122d and the limited part 132a are engaged, the limited part 132a is locked between the two protrusions 122a. The contact between the limited part 132a and the opposite end faces of the protrusions 122a restricts the limited part 132a from disengaging from the limiting part 122d, thereby reducing the risk of abnormal disengagement of the first connector assembly 12 and the second connector assembly 13.

[0136] At least one of the protrusion 122a and the limited portion 132a is elastic, so that during the process of the first connector 12 and the second connector 13 engaging or disengaging, at least one of the protrusion 122a and the limited portion 132a can be squeezed, so that the limited portion 132a can engage or disengage with the limited portion 122d.

[0137] More specifically, in order to facilitate the engagement or disengagement of the limited portion 132a and the limiting portion 122d, both the protrusion 122a and the limited portion 132a may be provided with guide surfaces.

[0138] Figure 6 shows a schematic diagram of the protrusion 122a abutting against the restrained portion 132a. Along the first direction Y, the restrained portion 132a has a first guide surface 132a1 on both sides, and the protrusion 122a has a second guide surface 122a1 on both sides. During the engagement or disengagement of the restrained portion 132a and the restrained portion 122d, the abutment of the first guide surface 132a1 and the second guide surface 122a1 guides the relative movement of the protrusion 122a and the restrained portion 132a, achieving a labor-saving effect while simultaneously allowing the connector 1 to be inserted and removed.

[0139] Figure 7 shows a schematic diagram of the second connector 131 in a specific embodiment. The second connector 131 is provided with a receiving cavity 131a, and the side wall of the receiving cavity 131a is provided with a slot 131a1 for holding the insulating member 133. Along the first direction Y, the lower side wall of the slot 131a1 is provided with an opening 131a2 to facilitate the insertion of the insulating member 133.

[0140] Figure 8 shows a schematic diagram of the structure of the second connector 131 and the insulating member 133. The second connector assembly 13 includes the second connector 131 and the insulating member 133. The insulating member 133 is engaged in the slot 131a1 through the opening 131a2. Referring to Figures 3, 7, and 8, the second conductive member 132 is installed on the insulating member 133. In this embodiment, to ensure the structural strength of the second connector 131, the second connector 131 is made of metal. Therefore, the insulating member 133 separates the second connector 131 and the second conductive member, achieving insulation and protection, and preventing the second conductive member 132 from being electrically connected to the support member 11 through the second connector 131, which could lead to a short circuit.

[0141] The insulating member 133 may be provided with a snap-fit ​​groove (not shown in the figure), and the second conductive member 132 is snapped into the snap-fit ​​groove. Alternatively, the second conductive member 132 may be fixed to the insulating member 133 by adhesive bonding. Furthermore, other methods may be used to fix the second conductive member 132 to the insulating member 133; this embodiment is not limited to these methods.

[0142] Similarly, a snap-fit ​​groove (not shown in the figure) can be provided on the outer side of the first connector 121, and the first conductive element 122 is snapped into the snap-fit ​​groove. Alternatively, the first conductive element 122 can be fixed to the first connector 121 by adhesive bonding, or other methods can be used to fix the first conductive element 122 to the first connector 121. This embodiment does not limit the specific methods used.

[0143] The above describes the possible mechanical structures for the first and second connector components. The following section details the specific methods by which the first and second conductive components are electrically connected.

[0144] In one embodiment, the first conductive element 122 and the second conductive element 132 can be electrically connected by having a portion of the structure of the first conductive element 122 in direct contact with a portion of the structure of the second conductive element 132.

[0145] Exemplary, in some embodiments, referring to Figures 2 to 4, a protrusion 122a is disposed on the first conductive member 122, and a limiting portion 132a is disposed on the second conductive member 132. In this embodiment, the first conductive member 122 and the second conductive member 132 may be conductive springs, the protrusion 122a is formed by bending a portion of the structure of the first conductive member 122, and the limiting portion 132a is formed by bending a portion of the structure of the second conductive member 132. When the first connector assembly 12 and the second connector assembly 13 are engaged, at least one of the limiting portion 132a and the protrusion 122a remains in contact with the portion of the conductive structure corresponding to the second direction X, thereby achieving electrical connection between the first conductive member 122 and the second conductive member 132.

[0146] For example, in one embodiment, the limited portion 132a abuts against the first conductive member 122 corresponding to the second direction X, while the protrusion 122a does not abut against the second conductive member 132 corresponding to the second direction X. In this case, by electrically connecting the limited portion 132a to the first conductive member 122, an electrical connection can be achieved between the conductive member 122 and the second conductive member 132. It should be noted that even if the protrusion 122a does not abut against the second conductive member 132, but the distance between the protrusion 122a and the second conductive member 132 along the second direction X is less than the thickness of the limited portion 132a along the second direction X, the protrusion 122a still functions as a limiter on the limited portion 132a.

[0147] In another embodiment, the protrusion 122a abuts against the second electrical component 132 corresponding to the second direction X, while the limited portion 132a does not abut against the first conductive component 122 corresponding to the second direction X. In this case, an electrical connection between the protrusion 122a and the second electrical component 132 is achieved. It should be noted that even if the limited portion 132a does not abut against the first conductive component 122, but the distance between the limited portion 132a and the first conductive component 122 along the second direction X is less than the thickness of the protrusion 122a along the second direction X, the protrusion 122a still functions to limit the limited portion 132a.

[0148] In another embodiment, the protrusion 122a abuts against the second electrical component 132 corresponding to the second direction X, and the limiting portion 132a abuts against the first conductive component 122 corresponding to the second direction X. At this time, the protrusion 122a is electrically connected to the second electrical component 132, and the limiting portion 132a is electrically connected to the first conductive component 122, thereby realizing the electrical connection between the conductive component 122 and the second conductive component 132.

[0149] In this embodiment, by providing a protrusion 122a on the first conductive member 122 and a limiting part 132a on the second conductive member 132, the first conductive member 122 and the second conductive member 132 can form an electrical connection through contact, while also limiting the first connector assembly 12 and the second connector assembly 13, thereby achieving a snap-fit ​​engagement between the first connector assembly 12 and the second connector assembly 13.

[0150] In some embodiments, FIG9 shows a schematic diagram of the second connector assembly 13 in another specific embodiment. The second connector assembly includes an insulating member 133 and a second conductive member 132. A limiting portion 132a is disposed on the insulating member 133, and the second conductive member 132 is disposed on at least one side of the limiting portion 132a along the first direction Y.

[0151] Figure 10 shows a schematic diagram of the mating state of the first connector assembly 12 and the second connector assembly 13 when the protrusion 122a is disposed on the first conductive member 122 and the limiting part 132a is disposed on the insulating member 133. Referring to Figures 2, 9, and 10, in this embodiment, the first conductive member 122 can be a conductive spring, and the insulating member 133 can be a plastic part. The protrusion 122a is formed by bending a portion of the structure of the first conductive member 122, and the limiting part 132a is formed by protruding a portion of the structure of the insulating member 133. When the first connector assembly 12 and the second connector assembly 13 are mating, the protrusion 122a abuts against a portion of the structure of the second conductive member 132 corresponding to the second direction X, thereby achieving an electrical connection between the first conductive member 122 and the second conductive member 132.

[0152] In this embodiment, a protrusion 122a is provided on the first conductive member 122, a limited portion 132a is provided on the insulating member 133, and a second conductive member 132 is provided on both sides of the limited portion 132a along the first direction Y. This allows the protrusion 122a to abut against the second conductive member 132, thereby achieving electrical connection between the first conductive member 122 and the second conductive member 132. At the same time, it can also limit the first connector assembly 12 and the second connector assembly 13, achieving a snap-fit ​​engagement between the first connector assembly 12 and the second connector assembly 13.

[0153] In some embodiments, FIG11 shows a schematic diagram of the first connector assembly 12 in another specific embodiment. The first connector assembly 12 includes a first connector 121 and a first conductive element 122. A protrusion 122a is disposed on the first connector 121. Along the first direction Y, the first conductive element 122 (the part in bold in the figure) is disposed between two protrusions 122a.

[0154] Figure 12 shows a schematic diagram of the mating state of the first connector assembly 12 and the second connector assembly 13 when the protrusion 122a is disposed on the first connector 121 and the limiting part 132a is disposed on the second conductive member 132. Referring to Figures 3, 11, and 12, in this embodiment, the second conductive member 132 can be a conductive spring. The protrusion 122a is formed by a portion of the structure of the first conductive member 122 protruding outwards, and the limiting part 132a is formed by bending a portion of the structure of the second conductive member 132. When the first connector assembly 12 and the second connector assembly 13 are mating, the limiting part 132a abuts against a portion of the structure of the first conductive member 122 corresponding to the second direction X, thereby achieving an electrical connection between the first conductive member 122 and the second conductive member 132.

[0155] In this embodiment, a protrusion 122a is provided in the first connector 121, and a first conductive member 122 is provided between the protrusions 122a. A limiting part 132a is provided in the second conductive member 132, so that the limiting part 132a abuts against the first conductive member 122. This achieves electrical connection between the first conductive member 122 and the second conductive member 132, while also limiting the first connector assembly 12 and the second connector assembly 13, thus achieving a snap-fit ​​engagement between the first connector assembly 12 and the second connector assembly 13.

[0156] In some embodiments, FIG13 shows a schematic diagram of the first connector assembly 12 in another specific embodiment. The first connector assembly 12 includes a first connector 121 and a first conductive element 122. The first conductive element 122 includes a first segment 122b and a second segment 122c distributed along a first direction Y. There is a gap between the first segment 122b and the second segment 122c, and the two can be electrically connected by a wire harness. Protrusions 122a are respectively disposed on the first segment 122b and the second segment 122c.

[0157] Figure 14 shows a schematic diagram of the mating state of the first connector assembly 12 and the second connector assembly 13, with a protrusion 122a disposed on the first segment 122b and the second segment 122c, and a limiting portion 132a disposed on the insulating member 133. Referring to Figures 9, 13, and 14, in this embodiment, the first segment 122b and the second segment 122c can be conductive springs, and the insulating member 133 can be a plastic part. The protrusion 122a is formed by bending a portion of the structure of the first segment 122b and the second segment 122c, and the limiting portion 132a is formed by a portion of the structure of the insulating member 133. When the first connector assembly 12 and the second connector assembly 13 are mated, the protrusion 122a abuts against a portion of the structure of the second conductive member 132 corresponding to the second direction X, thereby achieving an electrical connection between the first conductive member 122 and the second conductive member 132.

[0158] In this embodiment, a protrusion 122a is provided in the first segment 122b and the second segment 122c, a limited portion 132a is provided in the insulating member 133, and a second conductive member 132 is provided on both sides of the limited portion 132a along the first direction Y. This allows the protrusion 122a to abut against the second conductive member 132, thereby achieving electrical connection between the first conductive member 122 and the second conductive member 132. At the same time, it can also limit the first plug-in assembly 12 and the second plug-in assembly 13, thereby achieving the snap-fit ​​engagement between the first plug-in assembly 12 and the second plug-in assembly 13.

[0159] Alternatively, in this embodiment, a second connector assembly 13, which is limited by the limiting part 132a and disposed on the second conductive member 132, may be used. The specific details are the same as those described above, and will not be repeated in this embodiment.

[0160] Figure 15 shows a schematic diagram of the connector 1 in another specific embodiment. The connector 1 includes a support member 11, a first connector assembly 12, a second connector assembly 13, and a limiting assembly 14. The limiting assembly 14 is located within a sliding channel 111 and can slide relative to the support member 11 along the sliding channel 111. The limiting assembly 14 is connected to the first connector assembly 12. Along the second direction X, both ends of the limiting assembly 14 can abut against the support member 11 to support the first connector assembly 12 in a first position within the sliding channel 111 and keep it stationary. Alternatively, it can support the first connector assembly 12 and the second connector assembly 13 in a mating state in a second position within the sliding channel 111 and keep them stationary.

[0161] Figure 16 shows a schematic diagram of the first connector 12 and the limiting component 14 located in the support member 11. The support member 11 has a sliding channel 111 and a first opening 112a. The inner sidewall of the sliding channel 111 is provided with a limiting protrusion 111b. The limiting component 14 can abut against the limiting protrusion 111b along the first direction Y, so that the first connector 12 is fixed in the first position in the sliding channel 111.

[0162] It should be noted that, along the first direction Y, the area between the limiting protrusion 111b and the first opening 112a is defined as the limiting area A. The first position in which the first connector 12 is fixed within the sliding channel 111 refers to the situation where the limiting component 14 abuts against the limiting protrusion 111b (the limiting component 14 is located within the limiting area A), so that the second connector 13 can cooperate with the first connector 12. The second position in which the first connector 12 and the second connector 13 are fixed within the sliding channel 111 refers to the situation where the limiting component 14 abuts against the inner wall of the sliding channel 111 outside the limiting area A.

[0163] In other embodiments (not shown in the figure), when the limiting protrusion 111b restricts the first connector 12 to any position in the limiting region A by the limiting component 14, the first connector 12 can be completely located within the sliding channel 111. At this time, the first connector 12 is positioned close to the first opening 112a, which facilitates cooperation with the second connector 13 and reduces the risk of the first connector 12 being exposed and damaged.

[0164] In the embodiment shown in Figure 16, when the limiting protrusion 111b restricts the first connector 12 to any position in the limiting region A by the limiting component 14, part of the structure of the first connector 12 is located in the sliding channel 111, and another part of the structure of the first connector 12 can be exposed outside the sliding channel 111 through the first opening 112a so as to cooperate with the second connector 13.

[0165] After the first connector component and the second connector component are engaged, the structure of the two components can be located in the position shown in Figure 17 or in the position shown in Figure 18.

[0166] Specifically, after the first connector 12 and the second connector 13 are engaged, when the limiting component 14 is located within the limiting region A and abuts against the limiting protrusion 111b, the structure formed by the engagement of the first connector 12 and the second connector 13 is located outside the support member 111, as shown in Figure 17. When pressure is continuously applied to the structure formed by the engagement of the first connector 12 and the second connector 13, the limiting component 14 can move to below the limiting protrusion 111b, and at least a portion of the structure formed by the engagement of the first connector 12 and the second connector 13 extends into the sliding channel 111, which protects the structure formed by the engagement of the first connector 12 and the second connector 13.

[0167] Figure 19 shows a schematic diagram of the support member 11. Along the first direction Y, the support member 11 has a top 112 and a bottom 113. The top 112 is provided with a first opening 112a and a first blocking part 112b. The bottom 113 is provided with a second opening 113a and a second blocking part 113b. The second opening 113a is arranged opposite to the first opening 112a, and the second blocking part 113b is arranged opposite to the first blocking part 112b. The first blocking part 112 is used to prevent the first connector assembly 12 from disengaging from the sliding channel 111, and at the same time, it can prevent the second connector assembly 13 from taking the first connector assembly 13 out of the sliding channel 111, thereby realizing the disengagement of the first connector assembly 12 and the second connector assembly 13. The second blocking part 113 is used to prevent the first connector assembly 12 from disengaging from the sliding channel 111. The structure and effect of the first blocking part 112a and the second blocking part 113a are described in detail below.

[0168] Please continue to refer to Figure 19. The support member 11 has a sliding channel 111. The inner wall of the sliding channel 111 is provided with the aforementioned limiting protrusion 111b. The limiting protrusion 111b is located near the first opening 112a.

[0169] The cross-sectional shape of the limiting protrusion 111b can be circular, trapezoidal, arc-shaped, triangular, etc., and this embodiment does not impose a specific limitation. In the following description, this embodiment uses a triangular cross-sectional shape of the limiting protrusion 111b as an example.

[0170] Referring to Figure 19, along the first direction Y, the limiting protrusion 111b has a first limiting surface 111b1 and a second limiting surface 111b2. The first limiting surface 111b1 is located on one side of the first opening 112a and is inclined in a direction away from the first opening 112a. The second limiting surface 111b2 is located on the side away from the first opening 112a and is inclined in a direction closer to the first opening 112a, so that the limiting component 14 can move from above the limiting protrusion 111b to below the limiting protrusion 111b, and also from below the limiting protrusion 111b to above the limiting protrusion 111b, so that the first connecting component 12 and the second connecting component 13 can move within the entire sliding channel 111.

[0171] The inclination angle α of the first limiting surface 111b1 and the inclination angle β of the second limiting surface 111b2 satisfy: α < β. From the perspective shown in Figure 17, this embodiment, by setting α < β, ensures that the resistance encountered by the limiting component 14 when moving from below the limiting protrusion 111b to above the limiting protrusion 111b is less than the resistance encountered when moving from above the limiting protrusion 111b to below the limiting protrusion 111b. This ensures that the first connecting component 12 and the second connecting component 13 can complete the engagement above the limiting protrusion 111b, and that the first connecting component 12 and the second connecting component 13, in the engaged state, can move past the limiting protrusion 111b to above the limiting protrusion 111b without disengaging during the process of passing over the limiting protrusion 111b.

[0172] Based on the structure of the connector 1 in the above embodiments, the force values ​​that match each other during the process of pulling out, inserting and adjusting the stroke of the connector 1 must meet a certain relationship in order to realize the normal insertion and removal function of the connector 1.

[0173] Figure 17 shows a schematic diagram of the limiting component 14 abutting against the first limiting surface 111b1. Along the first direction Y, the resistance to the disengagement of the first connector 12 and the second connector 13 is a first force value F1. That is, when the pulling force applied to the first connector 12 or the second connector 13 is greater than or equal to the first force value F1, the first connector 12 and the second connector 13 can be disengaged. Correspondingly, when the pushing force applied to the first connector 12 or the second connector 13 reaches the first force value F1, the first connector 12 and the second connector 13 can cooperate. Referring to Figure 4, this first force value F1 can be the force required for the limiting part and the limited part to engage.

[0174] Along the first direction Y, after the first connector 12 and the second connector 13 are engaged, the resistance they experience from the limiting protrusion 111b when they move below it is the second force value F2. F1 and F2 must satisfy: F2 > F1.

[0175] Specifically, F2 is the resistance that the first connector 12 and the second connector 13 overcome when they move downward along the first direction Y out of the limiting area A after they cooperate.

[0176] In this embodiment, by setting F2 > F1, the external force applied to the first connector 12 and the second connector 13 when they cooperate will not cause the limiting component 14 to move downward to below the limiting protrusion 111b, so that the first connector 12 completes the cooperation with the second connector 13 within the limiting area A, which facilitates the cooperation between the first connector 12 and the second connector 13.

[0177] Figure 18 shows a schematic diagram of the first connector assembly 12 and the second connector assembly 13 in another position within the sliding channel 111. After the first connector assembly 12 and the second connector assembly 13 are engaged, the second connector can be pushed relative to the first connector until it abuts against the limiting component 14. The second connector then pushes the limiting component 14 along the first limiting surface 111b1 to below the limiting protrusion 111b, moving it out of the limiting area A, as shown in Figure 17. During this process, the first connector assembly 12 and the second connector assembly 13 remain engaged and electrically connected.

[0178] As described above, the resistance encountered when the first connector 12 disengages from the second connector 13 along the first direction Y is a first force value F1. During the sliding of the limiting component 14 along the sliding channel 111, the resistance of the inner wall of the sliding channel 111 to the limiting component 14 is a third force value F3. F1 and F3 must satisfy the condition: F1 > F3.

[0179] In this embodiment, by setting F1 > F3, when the first connector 12 and the second connector 13 are in a mating state, pressing the second connector 13 will cause the second connector 13 to drive the first connector 12 and the limiting component 14 to move synchronously within the sliding channel 111, thereby adjusting the headrest position and preventing the first connector 12 and the second connector 13 from disengaging, thus improving the reliability of the electrical connection between the first conductive element and the second conductive element when adjusting the headrest position.

[0180] Figure 20 shows a schematic diagram of the limiting component 14 abutting against the second limiting surface 111b2. As mentioned above, the resistance to the disengagement of the first connector component 12 and the second connector component 13 is the first force value F1. Along the first direction Y, after the first connector component 12 and the second connector component 13 are engaged, the resistance they experience from the limiting protrusion 111b when they move above it is the fourth force value F4. F1 and F4 must satisfy: F1 > F4.

[0181] Specifically, F4 represents the resistance encountered when the first connector 12 and the second connector 13 move upwards over the second limiting surface 111b2 to the limiting region A after they are engaged. In this embodiment, by setting F1 > F4, when the user applies an external force of the fourth force F4 to cause the first connector 12 and the second connector 13 to move upwards past the limiting protrusion 111b in the engaged state, this fourth force F4 will not cause the first connector 12 and the second connector 13 to disengage.

[0182] Figure 21 shows a schematic diagram of the connector installed on a seat. The seat includes a backrest 4, and a support member 11 is fixed to the backrest 4. Along the first direction Y, after the first connector assembly 12 and the second connector assembly 13 cooperate, the resistance encountered by the limiting protrusion 111b when they move below the limiting protrusion 111b is the second force value F2. Along the first direction Y, the resistance that causes the support member 11 to disengage from the backrest 4 is the fifth force value F5, that is, when the pulling force applied to the support member 11 reaches or exceeds the fifth force value F5, the support member 11 disengages from the backrest 4.

[0183] In this embodiment, by setting F5 > F2, when the user applies an external force to the plug-in device 1 to make the limiting component 14 move upward past the limiting protrusion 111b, the external force is less than the fifth force value F5 that causes the support member 11 to detach from the backrest 4, thus preventing the plug-in device 1 from detaching from the backrest 4 when it is pulled out.

[0184] In the above embodiments, the force values ​​must satisfy F5 > F2 > F1 > F4 and F1 > F3, so that the connector 1 will not detach from the backrest during the insertion and removal process, thereby improving the reliability of the first connector assembly 12 and the second connector assembly 13 during the engagement and disengagement process.

[0185] Referring to Figures 19 and 21, along the first direction Y, the support member 11 has a top 112 and a bottom 113. The top 112 is provided with a first opening 112a and a first blocking part 112b, and the bottom 113 is provided with a second opening 113a and a second blocking part 113b. The second opening 113a is arranged opposite to the first opening 112a, and the second blocking part 113b is arranged opposite to the first blocking part 112b. When it is necessary to disengage the first connector assembly 12 and the second connector assembly 13 (e.g., to remove the headrest), the second connector assembly 13 is pulled upward, so that the limiting assembly 14 can abut against the first blocking part 112b. The first blocking part 112b restricts the limiting assembly 14 and the first connector assembly 12 from continuing to move upward. At this time, the second connector assembly 13 is pulled out under the obstruction of the first blocking part 112b, thereby disengaging the first connector assembly 12 and the second connector assembly 13, while preventing the first connector assembly 12 from disengaging from the sliding channel 111.

[0186] Figure 22 shows a schematic diagram of the first connector 12 accidentally disengaging when it is engaged with the second connector 13. The bottom 113 of the support member 11 is provided with a second blocking part 113b. If the second connector 13 is inserted quickly, the impact force causes the first connector 12 to disengage from the limiting area A before it can engage with the second connector 13. At this time, the second blocking part 113b abuts against part of the limiting component 14 to block the limiting component 14 and the first connector 12, preventing them from falling onto the backrest.

[0187] Figure 23 shows a schematic diagram of the first connector assembly 12 and the second connector assembly 13 engaging in the state shown in Figure 22. At this time, under the obstruction of the second blocking part 113b, the second connector assembly 13 can re-engage with the first connector assembly 12. This embodiment, by providing the first blocking part 112b and the second blocking part 113b, can simultaneously achieve the disengagement of the first connector assembly 12 and the second connector assembly 13, while also providing bidirectional anti-disengagement, ensuring the stability of the connector device 1 during operation.

[0188] Figure 24 shows a schematic diagram of the limiting assembly 14 in one specific embodiment. The limiting assembly 14 includes a housing 143, an elastic member 142, and at least two limiting members 141, which are mounted on the housing 143. Along the second direction X, the two ends of the elastic member 142 are respectively connected to the two limiting members 141, and at least a portion of each of the two limiting members 141 can extend out of the housing 143. The elastic member 142 provides a thrust to the two limiting members 141 connected to its two ends, enabling the two limiting members 141 to maintain contact with the inner wall of the sliding channel 111.

[0189] Figure 25 shows a schematic diagram of the cooperation between the limiting component 14 and the support member 11. At this time, the two limiting members 141 abut against the inner wall of the sliding channel 111 and compress the elastic member 142, so that the elastic member 142 is in a compressed state and provides a thrust to the two limiting members 141, so as to maintain the limiting member 141 abutting against the inner wall of the sliding channel 111, thereby realizing that the first connecting component 12 stays at any position in the sliding channel 111.

[0190] The surface of the limiting member 141 that contacts the inner wall of the sliding channel 111 can be set as an arc surface 141a to improve the stability of the limiting member 141 moving along the inner wall of the sliding channel 111.

[0191] Further, please continue to refer to Figure 25. The outer side wall of the housing 143 is provided with a slider 143a, and the inner side wall of the sliding channel 111 is provided with a groove 111a. During the movement of the limiting component 14 along the sliding channel 111, the slider 143a and the groove 111a slide together to limit the movement trajectory of the limiting component 14, thereby ensuring the stability of the movement of the first connector component 12 / the first connector component 12 and the second connector component 13 within the sliding channel 111.

[0192] Alternatively, a groove 111a can be provided on the outer side wall of the housing 143, and a groove 111a can be provided on the inner side wall of the sliding channel 111, with the slider 143a slidingly engaging with the groove 111a.

[0193] In the above embodiments, the support member 11 may include a first support portion (not shown in the figure) and a second support portion (not shown in the figure). The first support portion and the second support portion are connected to form a first opening 112a, a sliding channel 111, and a second opening 113a. The assembly process of the support member 11, the first connector assembly 12, and the limiting assembly 14 is as follows: first, the limiting assembly 14 is assembled with the first connector assembly 12; then, the first support portion and the second support portion are fitted over the first connector assembly 12 and the limiting assembly 14; finally, the first support portion and the second support portion are fixed.

[0194] This embodiment also provides a seat, which includes a backrest, a headrest, and a connector 1. The headrest is detachably installed above the backrest and can be adjusted in position relative to the backrest. A support member 11 is installed on the backrest, and a second connector assembly 13 is installed on the headrest. A speaker is installed inside the headrest. This embodiment, by designing the aforementioned connector 1, achieves a detachable connection between the headrest and the backrest, and ensures normal power supply when the headrest is reinstalled on the backrest and its position is adjusted.

[0195] This embodiment also provides a vehicle, which includes a vehicle body and seats, with the seats mounted on the vehicle body. By configuring detachable headrests, the seats can be folded in half or reclined, greatly enhancing the experience of creating versatile interior spaces, home settings, and camping experiences.

[0196] Furthermore, the connector provided in this embodiment can be applied to any connector usage scenario that requires both plugging and unplugging as well as power supply.

[0197] The same or similar parts between the various embodiments in this specification can be referred to mutually. In particular, the device embodiments and terminal embodiments are basically similar to the method embodiments, so the description is relatively simple.
