Description

A plug-in member, plug-in device, seat and vehicle

[0001] The present application claims priority to the Chinese patent application No. 202420736915.8, filed on April 8, 2024, and entitled "A plug-in member, plug-in device, seat and vehicle", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of power connection, and in particular to a plug-in member, plug-in device, seat and vehicle. BACKGROUND

[0003] Car seat audio headrest configurations are gradually becoming popular, and many vehicle models, especially new energy vehicle models, are equipped with main driver audio headrests for functions such as private calls, navigation announcements, and music enjoyment. Since the audio needs to be powered on and the audio quality needs to be ensured, the solution for most seats is to lead the audio harness out from the seat headrest rod and connect it to the vehicle through the internal harness for power supply. In order to prevent the user from pulling out the headrest and breaking the harness, most audio headrests are designed to be non-removable or use a hidden lock to prevent pulling out.

[0004] Compared with traditional vehicles, new energy vehicles not only focus on driving experience, but also pay great attention to the creation of variable space, home scene and camping experience inside the vehicle. The configuration of non-removable audio headrests limits the folding or reclining of the seat, greatly limiting the creation of the aforementioned space scenes.

[0005] SUMMARY

[0006] The present application provides a plug-in member, plug-in device, seat and vehicle, which realizes the pluggable function and stable power supply of the audio headrest.

[0007] In a first aspect, the present application provides a plug-in member, comprising:

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

[0009] a first plug-in assembly installed in the sliding channel and capable of moving along the sliding channel;

[0010] a limiting assembly located in the sliding channel and capable of sliding along the sliding channel relative to the support member;

[0011] wherein the limiting assembly is capable of abutting with the limiting protrusion in a first direction, so as to fix the first plug-in assembly at a first position in the sliding channel.

[0012] In the present application, the region between the limiting protrusion and the first opening is defined as the limiting region. When the limiting protrusion limits the first connector assembly to any position in the limiting region through the limiting assembly, the first connector assembly can be completely located in the sliding channel, and at this time, the first connector assembly is arranged close to the first opening, which facilitates the cooperation with the second connector assembly and reduces the risk of damage of the exposed part of the first connector assembly.

[0013] Alternatively, when the limiting protrusion limits the first connector assembly to any position in the limiting region through the limiting assembly, part of the first connector assembly can be exposed outside the sliding channel through the first opening, so as to facilitate the cooperation with the second connector assembly.

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

[0015] In the present application, by arranging the first blocking portion and the second blocking portion, the first connector assembly can be bidirectionally prevented from being detached, thereby ensuring the stability of the connector device.

[0016] In a possible design, the limiting assembly comprises an elastic member and at least two limiting members, along the second direction, two ends of the elastic member are connected to the two limiting members respectively, and the limiting members are in a compressed state to make the limiting members abut against the inner wall of the sliding channel.

[0017] In the present application, the 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 pushing force to the two limiting members, to maintain the abutment of the limiting members against the inner wall of the sliding channel and keep the limiting members at any position.

[0018] In a possible design, the limiting assembly further comprises a housing, the elastic member and the two limiting members are mounted to the housing, and at least part of the two limiting members can extend out of the housing.

[0019] One of the outer side wall of the housing and the inner side wall of the sliding channel is provided with a sliding block, and the other is provided with a sliding groove, and the sliding block and the sliding groove are in sliding cooperation.

[0020] In the present application, by arranging the sliding block and the sliding groove in sliding cooperation, the movement track of the limiting assembly is limited, thereby ensuring the stability of the movement of the first connector assembly in the sliding channel.

[0021] The application provides a connector device in a second aspect, which comprises the connector member and a second connector assembly, the second connector assembly is plugged with the first connector assembly, and the second connector assembly is electrically connected with the first connector assembly.

[0022] In the application, the first connector assembly is electrically connected with the power supply of the whole vehicle through the backrest wire harness, and the second connector assembly is electrically connected with the sound in the headrest through the sound wire harness, when the first connector assembly is electrically connected with the second connector assembly, the sound wire harness and the backrest wire harness can be electrically connected, and the sound is powered through the power supply of the whole vehicle which is electrically connected with the backrest wire harness.

[0023] The first connector assembly and the second connector assembly can be detachably connected. Specifically, at least part of the second connector assembly can be inserted into the sliding channel through the first opening to cooperate with the first connector assembly, and the electrical connection and mechanical connection between the second connector assembly and the first connector assembly are realized. When the headrest is detached from the backrest, the sound wire harness and the backrest wire harness can be disconnected by detaching the first connector assembly and the second connector assembly, so as to prevent the wire harness from being pulled off when the headrest is detached. After the headrest is detached, the seat can be folded and reclined, which meets the various use scenarios of the user and improves the use experience.

[0024] In addition, when the first connector assembly is installed in the sliding channel, it can also slide along the sliding channel relative to the support, that is, the first connector assembly and the second connector assembly can slide in the sliding channel when they are in the cooperating state. When the angle of the headrest needs to be adjusted, that is, when the headrest rotates relative to the backrest, the second connector assembly installed on the headrest moves with the rotation of the headrest, and the second connector assembly drives the first connector assembly connected therewith to slide in the sliding channel, that is, when the headrest rotates, the first connector assembly and the second connector assembly can move synchronously, and they are still in the connected state, so as to keep normal power supply when the angle of the headrest is adjusted.

[0025] In a possible design, the first connector assembly comprises a first connector and a first conductive part, the first conductive part is installed on the outer side wall of the first connector, and the first connector assembly is provided with a limiting part;

[0026] The second connector assembly comprises a second connector and a second conductive part, the second connector is provided with a receiving cavity, the second conductive part is installed in the receiving cavity, the receiving cavity is provided with a limiting part, and the second connector assembly can move relative to the support, so that the connector device has at least a first state or a second state;

[0027] In the first state, a part of structure of the second connector assembly can extend into the sliding channel, so that at least part of the first connector assembly can extend into the accommodating cavity, the first conductive member and the second conductive member are electrically connected, and the limiting part and the limited part are matched; in the second state, the first conductive member and the second conductive member are electrically disconnected, and the limiting part and the limited part are matched.

[0028] In the present application, when the second connector assembly extends into the sliding channel through the first opening, at least part of the structure of the first connector assembly can extend into the accommodating cavity, so that the limiting part and the limited part are matched, the first conductive member and the second conductive member are electrically connected, and the first connector assembly and the second connector assembly are matched and electrically connected at the same time.

[0029] When the first connector assembly is separated from the accommodating cavity, the limiting part and the limited part are matched, the first conductive member and the second conductive member are electrically disconnected, and at this time, the second connector assembly is separated from the sliding channel, so that the first connector assembly and the second connector assembly are completely separated.

[0030] In the present application, through the matching of the limiting part and the limited part, when the first connector assembly and the second connector assembly in the matching state move in the sliding channel, the stability of the electrical connection between the first conductive member and the second conductive member can be ensured.

[0031] In a possible design, along the first direction, the resistance of the first connector assembly and the second connector assembly to separate is a first force value F1.

[0032] After the first connector assembly and the second connector assembly are matched along the first direction, the resistance of the limiting protrusion when the first connector assembly and the second connector assembly move to below the limiting protrusion is a second force value F2.

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

[0034] In the present application, by setting F2>F1, the external force applied to the first connector assembly and the second connector assembly to realize the matching of the two can not cause the limiting assembly to move downward to below the limiting protrusion, so that the first connector assembly can complete the matching with the second connector assembly 13 in the limiting area, and the matching of the first connector assembly and the second connector assembly is facilitated.

[0035] In a possible design, along the first direction, the resistance of the first connector assembly and the second connector assembly to separate is a first force value F1.

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

[0037] In the application, by setting F1>F3, when the first connector assembly and the second connector assembly are in the matching state, the second connector assembly can drive the first connector assembly and the limiting assembly to move synchronously in the sliding channel when the second connector assembly is pressed, so as to realize the adjustment of the position of the headrest and prevent the first connector assembly and the second connector assembly from being separated, thereby improving the reliability of the electrical connection between the first conductive part and the second conductive part when the position of the headrest is adjusted.

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

[0039] Along the first direction, when the first connector assembly and the second connector assembly are matched and move to the upper side of the limiting protrusion, the resistance of the limiting protrusion is a fourth force value F4.

[0040] F1 and F4 satisfy F1>F4.

[0041] In the application, by setting F1>F4, when the first connector assembly and the second connector assembly are in the matching state, the fourth force value F4 does not cause the first connector assembly and the second connector assembly to be disconnected during the process in which the first connector assembly and the second connector assembly move upward beyond the limiting protrusion under the external force of the fourth force value F4 applied by the user.

[0042] The application provides a connector device in a third aspect, which comprises:

[0043] A support member, which has a sliding channel in the support member;

[0044] A first connector assembly, which is installed in the sliding channel and can move along a first direction, comprises a first connector and a first conductive part, the first conductive part is installed on the outer side wall of the first connector, and the first connector assembly is provided with a limiting part;

[0045] A second connector assembly, which comprises a second connector and a second conductive part, the second connector is provided with a receiving cavity, the second conductive part is installed in the receiving cavity, the receiving cavity is provided with a limiting part, and the second connector assembly can move relative to the support member to make the connector device have at least a first state or a second state;

[0046] In the first state, a part of the structure of the second connector assembly can extend into the sliding channel, so that at least part of the first connector assembly can extend into the receiving cavity, the first conductive part and the second conductive part are electrically connected, and the limiting part and the limiting part are matched; in the second state, the first conductive part and the second conductive part are disconnected, and the limiting part and the limiting part are disconnected.

[0047] In the application, when the second connector assembly extends into the sliding channel through the first opening, at least part of the structure of the first connector assembly can extend into the accommodating cavity, so that the limiting part cooperates with the limited part, the first conductive part is electrically connected with the second conductive part, and the electrical connection of the first connector assembly and the second connector assembly is realized at the same time.

[0048] When the first connector assembly is out of the accommodating cavity, the limiting part is disengaged from the limited part, and the first conductive part is disengaged from the electrical connection with the second conductive part. At this time, the second connector assembly is out of the sliding channel, so that the first connector assembly and the second connector assembly are completely separated.

[0049] In the application, through the cooperation of the limiting part and the limited part, when the first connector assembly and the second connector assembly in the cooperating state move in the sliding channel, the stability of the electrical connection between the first conductive part and the second conductive part can be ensured.

[0050] In a possible design, along the first direction, the outer side wall of the first connector assembly is provided with at least two spaced-apart protruding parts, and the at least two protruding parts surround the limiting part. The limited part is a structure protruding towards the center of the accommodating cavity.

[0051] In the application, the limiting part is formed by at least two protruding parts along the first direction, and the limited part is a structure protruding towards the center of the accommodating cavity. When the limiting part cooperates with the limited part, the limited part is clamped between the two protruding parts. The limited part is limited from being disengaged from the limiting part by the abutment between the limited part and the opposite end faces of the protruding parts, so as to reduce the risk of the first connector assembly and the second connector assembly falling off.

[0052] At least one of the protruding part and the limited part is elastic, so that at least one of the protruding part and the limited part can be extruded during the cooperation or disengagement of the first connector assembly and the second connector assembly, so as to realize the cooperation or disengagement of the limited part and the limiting part.

[0053] In a possible design, the protruding part is arranged on the first conductive part, and the second conductive part is arranged on at least one side of the limited part along the first direction.

[0054] In the application, the first conductive part can be a conductive spring, the insulating part can be a plastic part, and the protruding part is formed by bending part of the structure of the first conductive part. When the first connector assembly cooperates with the second connector assembly, the protruding part abuts against part of the structure of the second conductive part along the second direction, so as to realize the electrical connection between the first conductive part and the second conductive part.

[0055] The application sets the protruding part on the first conductive part, sets the second conductive part on both sides of the limiting part along the first direction, and makes the protruding part abut against the second conductive part, so that the first conductive part and the second conductive part are in contact to form electrical connection, and the first connector assembly and the second connector assembly are limited at the same time, and the clamping cooperation of the first connector assembly and the second connector assembly is realized.

[0056] In a possible design, the second connector assembly further comprises an insulating part.

[0057] An inner side wall of the accommodating cavity is provided with a clamping groove, and the insulating part is installed in the clamping groove.

[0058] The second conductive part is installed on the insulating part.

[0059] In the application, in order to ensure the structural strength of the second connector, the second connector is made of metal, and the second connector is isolated from the insulating part, so as to achieve the effect of insulation and protection.

[0060] The insulating part is provided with a clamping groove, and the second conductive part is clamped in the clamping groove to be fixed on the insulating part. Alternatively, the second conductive part can be fixed on the insulating part by adhesion. Alternatively, other ways can be used to fix the second conductive part on the insulating part, which is not limited in the application.

[0061] In a possible design, the limiting part is arranged on the insulating part, and the second conductive part is arranged on at least one side of the limiting part along the first direction.

[0062] In the application, the first conductive part can be a conductive spring, the insulating part can be a plastic part, the protruding part is formed by bending part of the structure of the first conductive part, and the limiting part is formed by part of the structure of the insulating part. When the first connector assembly cooperates with the second connector assembly, the protruding part abuts against part of the structure of the corresponding second conductive part along the second direction, so as to realize electrical connection between the first conductive part and the second conductive part.

[0063] The application sets the protruding part on the first conductive part, sets the limiting part on the insulating part, and sets the second conductive part on both sides of the limiting part along the first direction, so that the protruding part abuts against the second conductive part, the first conductive part and the second conductive part are in contact to form electrical connection, and the first connector assembly and the second connector assembly are limited at the same time, and the clamping cooperation of the first connector assembly and the second connector assembly is realized.

[0064] In a possible design, the protruding part is arranged on the first conductive part, and the limiting part is arranged on the second conductive part.

[0065] In the present application, the first conductive part and the second conductive part can adopt conductive elastic sheets, the protruding part is formed by bending part of the structure of the first conductive part, and the limited part is formed by bending part of the structure of the second conductive part. When the first connector assembly and the second connector assembly are matched, at least one of the limited part and the protruding part keeps abutting with the corresponding part of the conductive structure along the second direction, that is, the electrical connection between the first conductive part and the second conductive part can be realized.

[0066] For example, in one case, the limited part keeps abutting with the first conductive part along the second direction, while the protruding part does not keep abutting with the second conductive part along the second direction. At this time, the electrical connection between the first conductive part and the second conductive part can be realized through the electrical connection between the limited part and the first conductive part. It should be noted that even if the protruding part does not keep abutting with the second conductive part, the distance between the protruding part and the second conductive part along the second direction X is smaller than the thickness of the limited part along the second direction, and the protruding part still plays a limiting role on the limited part.

[0067] In another embodiment, the protruding part keeps abutting with the second conductive part along the second direction, while the limited part does not keep abutting with the first conductive part along the second direction. At this time, the electrical connection between the first conductive part and the second conductive part can be realized through the electrical connection between the protruding part and the second conductive part. It should be noted that even if the limited part does not keep abutting with the first conductive part, the distance between the limited part and the first conductive part along the second direction is smaller than the thickness of the protruding part along the second direction, and the protruding part still plays a limiting role on the limited part.

[0068] In another embodiment, the protruding part keeps abutting with the second conductive part along the second direction, and the limited part keeps abutting with the first conductive part along the second direction. At this time, the electrical connection between the first conductive part and the second conductive part can be realized through the electrical connection between the protruding part and the second conductive part and the electrical connection between the limited part and the first conductive part.

[0069] In the present application, the protruding part is arranged on the first conductive part, and the first conductive part is arranged between the two protruding parts along the first direction; the limited part is arranged on the second conductive part.

[0070] In a possible design, the protruding part is arranged on the first connector, and the first conductive part is arranged between the two protruding parts along the first direction.

[0071] The limited part is arranged on the second conductive part.

[0072] In the present application, the second conductive part can adopt a conductive elastic sheet, and the protruding part is formed by the outward protruding of part of the structure of the first conductive part, and the limited part is formed by the bending of part of the structure of the second conductive part. When the first connector assembly is matched with the second connector assembly, the limited part keeps abutting with part of the structure of the first conductive part along the second direction, so as to realize the electrical connection between the first conductive part and the second conductive part.

[0073] In the present application, by setting the protruding part on the first connector, setting the first conductive part between the protruding parts, and setting the limited part on the second conductive part, the limited part abuts with the first conductive part, so as to realize the contact between the first conductive part and the second conductive part to form the electrical connection, and meanwhile, the first connector assembly and the second connector assembly can be limited, and the clamping matching of the first connector assembly and the second connector assembly can be realized.

[0074] In a fourth aspect, the present application provides a seat, comprising:

[0075] a backrest;

[0076] a headrest, which is detachably installed above the backrest and can be adjusted in position relative to the backrest;

[0077] a connector device, which is the connector device described above;

[0078] the support part is installed on the backrest, and the second connector assembly is installed on the headrest.

[0079] In the present application, by designing the connector device described above, the detachable connection between the headrest and the backrest can be realized, and the normal power supply when the headrest is installed on the backrest again and adjusted in position up and down can be ensured.

[0080] In a possible design, along the first direction, when the first connector assembly and the second connector assembly are matched and moved to below the limiting protrusion, the resistance of the limiting protrusion to the movement is a second force value F2;

[0081] Along the first direction, the resistance of the support part to the disengagement from the backrest is a fifth force value F5;

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

[0083] In the present application, when the user applies an external force to the connector device to make the limiting assembly move upward beyond the limiting protrusion, the external force is smaller than the fifth force value F5 of the support part to the disengagement from the backrest, so as to prevent the connector device from disengaging from the backrest when pulled out.

[0084] In a fifth aspect, the present application provides a vehicle, comprising:

[0085] a vehicle body;

[0086] A seat is provided, wherein the seat is the seat described above, and the seat is installed on the vehicle body.

[0087] In the present application, by setting the configuration of the detachable headrest, the folding or rearward tilting of the seat is realized, greatly improving the experience of creating variable space, home scene and camping experience in the vehicle. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0114] With the advent of the electrification era, the configuration of the vehicle electrical appliances is getting higher and higher, and the audio headrest gradually popularizes. The audio headrest and the vehicle power supply are connected through a wire harness to realize the functions of the headrest playing, navigation broadcasting, music, etc. However, in the related technology, the wire harness connecting the audio headrest and the vehicle power supply does not have a dismounting function, which leads to the problem that the audio headrest cannot be dismounted or dismounting the audio headrest easily leads to the wire harness breaking.

[0115] To this end, the embodiment provides a plug-in device to solve the above technical problems. The possible structure of the plug-in device is described in detail below in combination with the drawings.

[0116] As shown in FIG. 1, it is a schematic diagram of the structure of part of the plug-in device 1. The plug-in device 1 includes a support 11, a first plug-in assembly 12, a second plug-in assembly 13, an audio wire harness 2 and a backrest wire harness 3. In the plug-in device 1 provided by the embodiment of the present application, when the first plug-in assembly 12 and the second plug-in assembly 13 are electrically connected, the audio wire harness 2 and the backrest wire harness 3 can be electrically connected. Since the vehicle power supply is connected with the backrest wire harness 3, the power supply of the vehicle power supply to the audio (audio provided in the headrest) can be realized.

[0117] Among them, the support 11 and the first plug-in assembly 12 are installed on the backrest, and the second plug-in assembly 13 is installed on the headrest. Specifically, the support 11 is a metal frame structure, a plastic bracket structure, etc. The support 11 is installed on the backrest (not shown in the figure), and the support 11 has a first opening 112a in communication. The audio wire harness 2 extends to the audio via the first opening 112a.

[0118] Among them, 112a can be opened in the first blocking part 112, along the first direction Y, the first blocking part 112 is the top structure of the support 11, and the first blocking part 112 is used to block the first plug-in assembly 12 from sliding out of the sliding channel 111, and can resist the second plug-in assembly 13 from taking the first plug-in assembly 13 out of the sliding channel 111, so as to realize the disengagement of the first plug-in assembly 12 and the second plug-in assembly 13.

[0119] The support 11 also has a sliding channel 111, and the first plug-in assembly 12 is installed in the sliding channel 111, so that the first plug-in assembly 12 can slide along the sliding channel 111.

[0120] The support 11 also has a second opening 113a, and the first plug-in assembly 12 is electrically connected with the backrest wire harness 3. The backrest wire harness 3 is used to extend to the vehicle power supply (not shown in the figure) via the second opening 113a to be electrically connected.

[0121] Among them, 113a can be opened in the second blocking part 113, along the first direction Y, the second blocking part 113 is the bottom structure of the support 11, and the second blocking part 113 is used to block the first plug-in assembly 12 from sliding out of the sliding channel 111.

[0122] The second connector assembly 13 is electrically connected with the audio harness 2 in the headrest, and the audio harness 2 is electrically connected with the headrest (audio provided in the headrest). Therefore, when the first connector assembly 12 is electrically connected with the second connector assembly 13, the audio harness 2 and the backrest harness 3 can be electrically connected, and the audio electrically connected with the audio harness 2 is powered by the whole vehicle power supply electrically connected with the backrest harness 3.

[0123] The first connector assembly 12 and the second connector assembly 13 can be detachably connected. Specifically, at least part of the second connector assembly 13 can be inserted into the sliding channel 111 through the first opening 112a to cooperate with the first connector assembly 12, so as to realize the electrical connection and mechanical connection of the second connector assembly 13 and the first connector assembly 12. Moreover, when the headrest is detached from the backrest, the audio harness 2 and the backrest harness 3 can be disconnected by detaching the first connector assembly 12 and the second connector assembly 13, so as to prevent the harness from being pulled off when the headrest is detached. After the headrest is detached, the seat can be folded and reclined, so as to meet various use scenarios of users and improve the use experience.

[0124] In addition, when the first connector assembly 12 is installed in the sliding channel 111, it can also slide along the sliding channel 111 relative to the support 11, that is, the first connector assembly 12 and the second connector assembly 13 can slide in the sliding channel 111 when they are in the cooperating state. When it is necessary to adjust the angle of the headrest, that is, when the headrest rotates relative to the backrest, the second connector assembly 13 installed on the headrest moves with the rotation of the headrest, and the second connector assembly 13 drives the first connector assembly 12 connected thereto to slide in 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 they are still in the connected state, so as to keep normal power supply when the angle of the headrest is adjusted.

[0125] The specific structure of the detachable connection of the first connector assembly 12 and the second connector assembly 13 will be described below.

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

[0127] As shown in FIG. 2, it is a schematic view of the first connector assembly 12, which includes a first connector 121 and a first conductive part 122, and the first conductive part 122 is installed on the outer side wall of the first connector 121. When the first connector assembly 12 cooperates with the second connector assembly 13, the first conductive part 122 is used for conduction with the second connector assembly 13. The second conductive part 122 is also used for electrical connection with the backrest 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-apart protrusions 122a, which enclose a limiting portion 122d. When the first connector assembly 12 is mated with the second connector assembly 13, the limiting portion 122d is used to limit the mating with the second connector assembly 13.

[0129] As shown in FIG. 3 is a schematic view of the second connector assembly 13, which comprises a second connector 131, a second conductive member 132 and an insulating member 133 (to be specifically described below). The second connector 131 is provided with a receiving cavity 131a, and the second conductive member 132 is installed in the receiving cavity 131a, and when the first connector assembly 12 is mated with the second connector assembly 13, the second conductive member 132 can be in conduction with the first connector assembly 12. The second conductive member 132 is also used to be electrically connected with the sound wire harness 2.

[0130] The receiving cavity 131a is provided with a limiting portion 132a, which is protruded towards the center of the receiving cavity 131a along the second direction X. When the first connector assembly 12 is mated with the second connector assembly 13, the limiting portion 132a is used to limit the mating with the first connector assembly 12.

[0131] The connector device 1 has at least a first state (mating state) and a second state (unmating state). As shown in FIG. 4 is a schematic view of the first connector assembly 12 and the second connector assembly 13 in the mating state, please refer to FIG. 1 and FIG. 4, in the first state, a part of the structure of the second connector assembly 13 can extend into the sliding channel 111, so that at least a part of the first connector assembly 12 can extend into the receiving cavity 131a. At this time, the first conductive member 122 and the second conductive member 132 are electrically connected, and the limiting portion 122d is mated with the limiting portion 132a.

[0132] As shown in FIG. 5 is a schematic view of the first connector assembly 12 and the second connector assembly 13 in the unmating state, in the second state, the first connector assembly 12 can be pulled out of the receiving cavity 131a, at this time, the first conductive member 122 and the second conductive member 132 are electrically disconnected, and the limiting portion 122d is unmated with the limiting portion 132a. The second connector assembly 13 can be further pulled out of the sliding channel 111.

[0133] In the embodiment, when the second connector assembly 13 extends into the sliding channel 111 through the first opening 112a, at least part of the structure of the first connector assembly 12 can extend into the accommodating cavity 131a, so that the limiting portion 122d cooperates with the limited portion 132a, the first conductive part 122 is electrically connected with the second conductive part 132, the electrical connection of the first connector assembly 12 and the second connector assembly 13 is realized at the same time, and then the electrical connection of the sound wire harness 2 and the backrest wire harness 3 is realized, and further the electrical connection of the headrest and the vehicle power supply is realized. When the angle of the headrest is adjusted, the cooperation of the limiting portion 122d and the limited portion 132a can ensure the stability of the electrical connection between the first conductive part 122 and the second conductive part 132 when the first connector assembly 12 and the second connector assembly 13 in the cooperating state move in the sliding channel 111, and the reliable electrical connection between the headrest and the vehicle power supply can still be realized when the angle of the headrest is adjusted.

[0134] When the first connector assembly 12 is out of the accommodating cavity 131a, the limiting portion 122d and the limited portion 132a are disengaged, and the first conductive part 122 and the second conductive part 132 are disengaged. At this time, the second connector assembly 13 is out of the sliding channel 111, so that the second connector assembly connected with the headrest and the first connector assembly connected with the backrest are disengaged, and further the headrest can be disassembled.

[0135] Specifically, the limiting portion 122d is formed around the first direction Y by at least two protruding portions 122a, and the limited portion 132a is a structure protruding towards the center of the accommodating cavity 131a. When the limiting portion 122d cooperates with the limited portion 132a, the limited portion 132a is clamped between the two protruding portions 122a, and the limited portion 132a is limited from disengaging from the limiting portion 122d by the abutment between the limited portion 132a and the opposite end face of the protruding portion 122a, thereby reducing the risk of abnormal disengagement of the first connector assembly 12 and the second connector assembly 13.

[0136] Among them, at least one of the protruding portion 122a and the limited portion 132a has elasticity, so that at least one of the protruding portion 122a and the limited portion 132a can be extruded during the cooperation or disengagement of the first connector assembly 12 and the second connector assembly 13, so that the limited portion 132a can cooperate or disengage with the limiting portion 122d.

[0137] More specifically, in order to facilitate the cooperation or disengagement of the limited portion 132a and the limiting portion 122d, the protruding portion 122a and the limited portion 132a can be provided with a guide surface.

[0138] As shown in Fig. 6 is a schematic view of the abutment of the protruding portion 122a and the limiting portion 132a, along the first direction Y, the two sides of the limiting portion 132a are provided with first guide surfaces 132a1, and the two sides of the protruding portion 122a are provided with second guide surfaces 122a1. In the process of cooperation or disengagement of the limiting portion 122d and the limiting portion 132a, the abutment of the first guide surfaces 132a1 and the second guide surfaces 122a1 guides the relative movement of the protruding portion 122a and the limiting portion 132a, and achieves the labor-saving effect while plugging the connector 1.

[0139] As shown in Fig. 7 is a schematic view 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 clamping groove 131a1 for clamping the insulating member 133. Along the first direction Y, the lower side wall of the clamping groove 131a1 is provided with an opening 131a2 for facilitating the clamping of the insulating member 133.

[0140] As shown in Fig. 8 is a structural schematic view of the cooperation 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, and the insulating member 133 is clamped in the clamping groove 131a1 through the opening 131a2. Please refer to Figs. 3, 7 and 8, the second conductive member 132 is installed on the insulating member 133. In order to ensure the structural strength of the second connector 131, the second connector 131 is made of metal in this embodiment, so that the second connector 131 and the second conductive member are separated by the insulating member 133, thereby achieving the effect of insulation and protection, and preventing the second conductive member 132 from being electrically connected to the support 11 through the second connector 131 to cause short circuit.

[0141] Among them, the insulating member 133 can be provided with a clamping groove (not shown in the figure), and the second conductive member 132 is clamped in the clamping groove. Alternatively, the second conductive member 132 can also be fixed on the insulating member 133 by adhesion. Alternatively, other ways can also be used to fix the second conductive member 132 and the insulating member 133, which are not limited in this embodiment.

[0142] Similarly, the outer side of the first connector 121 can be provided with a clamping groove (not shown in the figure), and the first conductive member 122 is clamped in the clamping groove. Alternatively, the first conductive member 122 can also be fixed on the first connector 121 by adhesion, or other ways can also be used to fix the first conductive member 122 and the first connector 121, which are not limited in this embodiment.

[0143] The above is the possible structure of the first connector assembly and the second connector assembly. The specific way of electrical connection of the first conductive member and the second conductive member is described below.

[0144] In one embodiment, the first conductive member 122 and the second conductive member 132 can be electrically connected in the following manner: a part of the structure of the first conductive member 122 directly contacts a part of the structure of the second conductive member 132.

[0145] For example, in some embodiments, please continue to refer to FIGS. 2-4, the protruding portion 122a is arranged on the first conductive member 122, and the limiting portion 132a is arranged on the second conductive member 132. In this embodiment, the first conductive member 122 and the second conductive member 132 can be conductive springs, the protruding portion 122a is formed by bending a part of the structure of the first conductive member 122, and the limiting portion 132a is formed by bending a part of the structure of the second conductive member 132. When the first connector assembly 12 and the second connector assembly 13 are matched, at least one of the limiting portion 132a and the protruding portion 122a abuts against the corresponding part of the conductive structure along the second direction X, thereby realizing the electrical connection between the first conductive member 122 and the second conductive member 132.

[0146] For example, in one embodiment, the limiting portion 132a abuts against the first conductive member 122 along the second direction X, while the protruding portion 122a does not abut against the second conductive member 132 along the second direction X. At this time, the electrical connection between the first conductive member 122 and the second conductive member 132 is realized by the electrical connection between the limiting portion 132a and the first conductive member 122. It should be noted that even if the protruding portion 122a does not abut against the second conductive member 132, the protruding portion 122a still limits the limiting portion 132a as long as the distance between the protruding portion 122a and the second conductive member 132 along the second direction X is smaller than the thickness of the limiting portion 132a along the second direction X.

[0147] For example, in another embodiment, the protruding portion 122a abuts against the second conductive member 132 along the second direction X, while the limiting portion 132a does not abut against the first conductive member 122 along the second direction X. At this time, the electrical connection between the first conductive member 122 and the second conductive member 132 is realized by the electrical connection between the protruding portion 122a and the second conductive member 132. It should be noted that even if the limiting portion 132a does not abut against the first conductive member 122, the limiting portion 132a still limits the protruding portion 122a as long as the distance between the limiting portion 132a and the first conductive member 122 along the second direction X is smaller than the thickness of the protruding portion 122a along the second direction X.

[0148] For example, in another embodiment, the protruding portion 122a abuts against the second conductive member 132 along the second direction X, and the limiting portion 132a abuts against the first conductive member 122 along the second direction X. At this time, the electrical connection between the first conductive member 122 and the second conductive member 132 is realized by the electrical connection between the protruding portion 122a and the second conductive member 132 and the electrical connection between the limiting portion 132a and the first conductive member 122.

[0149] The first conductive member 122 and the second conductive member 132 are in contact to form an electrical connection, and the first connector assembly 12 and the second connector assembly 13 are limited.

[0150] In some embodiments, as shown in FIG. 9, which is a schematic view 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. The limiting portion 132a is arranged on the insulating member 133, and the second conductive member 132 is arranged on at least one side of the limiting portion 132a along the first direction Y.

[0151] As shown in FIG. 10, which is a schematic view of the first connector assembly 12 and the second connector assembly 13 in a matching state when the protruding portion 122a is arranged on the first conductive member 122 and the limiting portion 132a is arranged on the insulating member 133. Please refer to FIGS. 2, 9 and 10, in the embodiment, the first conductive member 122 can be a conductive spring, the insulating member 133 can be a plastic member, the protruding portion 122a is formed by bending part of the structure of the first conductive member 122, and the limiting portion 132a is formed by protruding part of the structure of the insulating member 133. When the first connector assembly 12 and the second connector assembly 13 are matched, the protruding portion 122a and part of the structure of the second conductive member 132 corresponding to the second direction X are in abutment, so as to realize the electrical connection between the first conductive member 122 and the second conductive member 132.

[0152] The protruding portion 122a and the second conductive member 132 are in abutment, the first conductive member 122 and the second conductive member 132 are in contact to form an electrical connection, and the first connector assembly 12 and the second connector assembly 13 are limited.

[0153] In some embodiments, as shown in FIG. 11, which is a schematic view of the first connector assembly 12 in another specific embodiment, the first connector assembly 12 includes a first connector 121 and a first conductive member 122. The protruding portion 122a is arranged on the first connector 121, and the first conductive member 122 (the thick line part in the figure) is arranged between the two protruding portions 122a along the first direction Y.

[0154] As shown in FIG. 12, when the protruding portions 122a are arranged on the first connector 121, and the limiting portions 132a are arranged on the second conductive member 132, the first connector assembly 12 and the second connector assembly 13 are in the mating state. Please refer to FIGS. 3, 11 and 12, in the embodiment, the second conductive member 132 can be a conductive spring, and the protruding portions 122a are formed by the outward protruding of the partial structure of the first conductive member 122, and the limiting portions 132a are formed by the bending of the partial structure of the second conductive member 132. When the first connector assembly 12 and the second connector assembly 13 are mated, the limiting portions 132a and the partial structure of the first conductive member 122 corresponding to the second direction X are in abutment, so as to realize the electrical connection between the first conductive member 122 and the second conductive member 132.

[0155] In the embodiment, the protruding portions 122a are arranged on the first connector 121, and the first conductive member 122 is arranged between the protruding portions 122a, and the limiting portions 132a are arranged on the second conductive member 132, so that the limiting portions 132a are in abutment with the first conductive member 122, thereby realizing the contact between the first conductive member 122 and the second conductive member 132 to form the electrical connection, and meanwhile, the limiting portions 132a can limit the first connector assembly 12 and the second connector assembly 13, so as to realize the clamping and mating of the first connector assembly 12 and the second connector assembly 13.

[0156] In some embodiments, as shown in FIG. 13, the first connector assembly 12 is in another specific embodiment, and the first connector assembly 12 includes the first connector 121 and the first conductive member 122, the first conductive member 122 includes the first segment 122b and the second segment 122c distributed along the first direction Y, the first segment 122b and the second segment 122c have a spacing therebetween, and the two segments can be electrically connected by a wire harness. The protruding portions 122a are arranged on the first segment 122b and the second segment 122c, respectively.

[0157] As shown in FIG. 14, when the protruding portions 122a are arranged on the first segment 122b and the second segment 122c, and the limiting portions 132a are arranged on the insulating member 133, the first connector assembly 12 and the second connector assembly 13 are in the mating state. Please refer to FIGS. 9, 13 and 14, in the embodiment, the first segment 122b and the second segment 122c can be conductive springs, the insulating member 133 can be a plastic member, the protruding portions 122a are formed by the bending of the partial structure of the first segment 122b and the second segment 122c, and the limiting portions 132a are formed by the partial structure of the insulating member 133. When the first connector assembly 12 and the second connector assembly 13 are mated, the protruding portions 122a and the partial structure of the second conductive member 132 corresponding to the second direction X are in abutment, so as to realize the electrical connection between the first conductive member 122 and the second conductive member 132.

[0158] In this embodiment, the protruding portion 122a is arranged on the first segment 122b and the second segment 122c, the limiting portion 132a is arranged on the insulating member 133, and the second conductive member 132 is arranged on both sides of the limiting portion 132a along the first direction Y, so that the protruding portion 122a can abut against the second conductive member 132. Thus, the first conductive member 122 can be in contact with the second conductive member 132 to form an electrical connection, and the first connector assembly 12 and the second connector assembly 13 can be limited, thereby achieving the clamping cooperation of the first connector assembly 12 and the second connector assembly 13.

[0159] Alternatively, in this embodiment, the limiting portion 132a can be arranged on the second connector assembly 13 of the second conductive member 132, and the specific content is the same as the above, which will not be described herein.

[0160] As shown in FIG. 15, the connector device 1 in another specific embodiment 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 arranged in the sliding channel 111 and can slide relative to the support member 11 along the sliding channel 111. The limiting assembly 14 is connected with 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 position of the first connector assembly 12 in the sliding channel 111, or can support the second position of the first connector assembly 12 and the second connector assembly 13 in the sliding channel 111 in the cooperating state.

[0161] As shown in FIG. 16, the first connector assembly 12 and the limiting assembly 14 are arranged in the support member 11. The support member 11 has a sliding channel 111 and a first opening 112a. The inner side wall of the sliding channel 111 is provided with a limiting protrusion 111b. The limiting assembly 14 can abut against the limiting protrusion 111b along the first direction Y, so that the first connector assembly 12 is fixed at the first position in the sliding channel 111.

[0162] It should be noted that along the first direction Y, the region between the limiting protrusion 111b and the first opening 112a is defined as a limiting region A. The first connector assembly 12 fixed at the first position in the sliding channel 111 means that the limiting assembly 14 abuts against the limiting protrusion 111b (the limiting assembly 14 is located in the limiting region A), so as to facilitate the cooperation of the second connector assembly 13 and the first connector assembly 12. The first connector assembly 12 and the second connector assembly 13 fixed at the second position in the sliding channel 111 means that the limiting assembly 14 abuts against the inner wall of the sliding channel 111 at a position outside the limiting region A.

[0163] In other embodiments (not shown in the figures), when the limiting protrusion 111b limits the first connector assembly 12 to any position in the limiting area A by the limiting assembly 14, the first connector assembly 12 can be completely located in the sliding channel 111, and at this time, the first connector assembly 12 is arranged close to the first opening 112a, facilitating the cooperation with the second connector assembly 13 and reducing the risk of damage to the exposed part of the first connector assembly 12.

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

[0165] After the first connector assembly cooperates with the second connector assembly, the structure of the cooperation can be located at the position shown in FIG. 17 or at the position shown in FIG. 18.

[0166] Specifically, after the first connector assembly 12 cooperates with the second connector assembly 13, when the limiting assembly 14 is located in the limiting area A and abuts against the limiting protrusion 111b, the structure of the cooperation between the first connector assembly 12 and the second connector assembly 13 is located outside the support 111, as shown in FIG. 17. When the pressure on the structure of the cooperation between the first connector assembly 12 and the second connector assembly 13 is continuously applied, the limiting assembly 14 can move below the limiting protrusion 111b, and at least part of the structure of the cooperation between the first connector assembly 12 and the second connector assembly 13 extends into the sliding channel 111, thereby protecting the structure of the cooperation between the first connector assembly 12 and the second connector assembly 13 through the sliding channel 111.

[0167] As shown in FIG. 19, it is a schematic view of the support 11. In the first direction Y, the support 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. The first blocking part 112 is used to block the first connector assembly 12 from coming out of the sliding channel 111, and can also resist the second connector assembly 13 from taking the first connector assembly 13 out of the sliding channel 111, thereby realizing the disconnection of the cooperation between the first connector assembly 12 and the second connector assembly 13. The second blocking part 113 is used to block the first connector assembly 12 from coming out of the sliding channel 111. The structure and effect of the first blocking part 112a and the second blocking part 113a will be described in detail below.

[0168] Please continue to refer to FIG. 19, the support 11 has a sliding channel 111, the inner wall of the sliding channel 111 is provided with the limiting protrusion 111b described above, and the limiting protrusion 111b is arranged close to the first opening 112a.

[0169] The cross-sectional shape of the limiting protrusion 111b can be circular, trapezoidal, arc-shaped, triangular, etc., which is not specifically limited in the embodiment. The cross-sectional shape of the limiting protrusion 111b is taken as triangular in the following description of the embodiment.

[0170] Please continue to refer to FIG. 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 the first limiting surface 111b1 is inclined in a direction away from the first opening 112a. The second limiting surface 111b2 is located on a side away from the first opening 112a, and the second limiting surface 111b2 is inclined in a direction close to the first opening 112a. In this way, the limiting assembly 14 can move from above the limiting protrusion 111b to below the limiting protrusion 111b, and also move from below the limiting protrusion 111b to above the limiting protrusion 111b, so that the first connector assembly 12 and the second connector assembly 13 can move in 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 FIG. 17, by setting α < β, the resistance that the limiting assembly 14 receives when moving from below the limiting protrusion 111b to above the limiting protrusion 111b is smaller than the resistance that the limiting assembly 14 receives when moving from above the limiting protrusion 111b to below the limiting protrusion 111b. This ensures that the first connector assembly 12 and the second connector assembly 13 can be matched above the limiting protrusion 111b, and the first connector assembly 12 and the second connector assembly 13 in the matched state can move above the limiting protrusion 111b without causing the first connector assembly 12 and the second connector assembly 13 to disengage during the process of moving over the limiting protrusion 111b.

[0172] Based on the structure of the connector device 1 in the above embodiments, the force values matched with each other during the pulling out, insertion and stroke adjustment of the connector device 1 need to satisfy certain size relationship to realize the normal plugging function of the connector device 1.

[0173] As shown in Fig. 17, a schematic view of the limiting assembly 14 abutting against the first limiting surface 111b1. In the first direction Y, the resistance of the first connector assembly 12 and the second connector assembly 13 disengaging is the first force value F1. That is, when the pulling force applied to the first connector assembly 12 or the second connector assembly 13 is greater than or equal to the first force value F1, the first connector assembly 12 and the second connector assembly 13 can be disconnected. Correspondingly, when the pushing force applied to the first connector assembly 12 or the second connector assembly 13 reaches the first force value F1, the first connector assembly 12 and the second connector assembly 13 can be matched. Please refer to Fig. 4, the first force value F1 can be the force required for the limiting part and the limited part to be connected.

[0174] In the first direction Y, after the first connector assembly 12 and the second connector assembly 13 are matched, the resistance of the limiting protrusion 111b when the two assemblies move below the limiting protrusion 111b is the second force value F2. F1 and F2 need to satisfy: F2>F1.

[0175] Specifically, F2 is the resistance of the first connector assembly 12 and the second connector assembly 13 moving downward out of the limiting area A in the first direction Y by overcoming the resistance of the first limiting surface 111b1 after the two assemblies are matched.

[0176] In this embodiment, by setting F2>F1, the external force applied to the first connector assembly 12 and the second connector assembly 13 to realize the matching of the two assemblies will not cause the limiting assembly 14 to move downward below the limiting protrusion 111b, so that the first connector assembly 12 completes the matching with the second connector assembly 13 in the limiting area A, facilitating the matching of the first connector assembly 12 and the second connector assembly 13.

[0177] As shown in Fig. 18, a schematic view of the structure of the matched first connector assembly 12 and the second connector assembly 13 in another position in the sliding channel 111. After the first connector assembly 12 and the second connector assembly 13 are matched, the second connector assembly can be moved relative to the first connector assembly to abut against the limiting assembly 14, and the second connector assembly can be used to push the limiting assembly 14 to move along the first limiting surface 111b1 to below the limiting protrusion 111b and move out of the limiting area A, as shown in Fig. 17. In this process, the first connector assembly 12 and the second connector assembly 13 still remain matched and electrically connected.

[0178] As described above, in the first direction Y, the resistance of the first connector assembly 12 and the second connector assembly 13 disengaging is the first force value F1. In the process of the limiting assembly 14 sliding in the sliding channel 111, the resistance of the inner wall of the sliding channel 111 to the limiting assembly 14 is the third force value F3. F1 and F3 need to satisfy: F1>F3.

[0179] The embodiment sets F1>F3, so that when the first connector assembly 12 and the second connector assembly 13 are in the matched state, the second connector assembly 13 can drive the first connector assembly 12 and the limiting assembly 14 to move synchronously in the sliding channel 111 when the second connector assembly 13 is pressed, so as to realize the adjustment of the position of the headrest and prevent the first connector assembly 12 and the second connector assembly 13 from being separated, and improve the reliability of the electrical connection between the first conductive part and the second conductive part when the position of the headrest is adjusted.

[0180] As shown in FIG. 20, it is a schematic view of the limiting assembly 14 abutting against the second limiting surface 111b2. As described above, the resistance of the first connector assembly 12 and the second connector assembly 13 from being separated is the first force value F1. When the first connector assembly 12 and the second connector assembly 13 are matched and moved above the limiting protrusion 111b in the first direction Y, the resistance of the limiting protrusion 111b is the fourth force value F4. F1 and F4 need to satisfy F1>F4.

[0181] Specifically, F4 is the resistance of the first connector assembly 12 and the second connector assembly 13 from being moved upward to the limiting area A by overcoming the second limiting surface 111b2 after the first connector assembly 12 and the second connector assembly 13 are matched. The embodiment sets F1>F4, so that the fourth force value F4 does not cause the first connector assembly 12 and the second connector assembly 13 to be disconnected during the process that the user applies the fourth force value F4 of external force to make the first connector assembly 12 and the second connector assembly 13 move upward beyond the limiting protrusion 111b when they are in the matched state.

[0182] As shown in FIG. 21, it is a schematic view of the connector device installed on the seat. The seat includes a backrest 4, and the support 11 is fixed on the backrest 4. When the first connector assembly 12 and the second connector assembly 13 are matched and moved below the limiting protrusion 111b in the first direction Y, the resistance of the limiting protrusion 111b is the second force value F2. In the first direction Y, the resistance of the support 11 from being separated from the backrest 4 is the fifth force value F5, that is, when the pulling force applied to the support 11 reaches or is greater than the fifth force value F5, the support 11 is separated from the backrest 4.

[0183] The embodiment sets F5>F2, so that when the user applies external force to the connector device 1 to make the limiting assembly 14 move upward beyond the limiting protrusion 111b, the external force is less than the fifth force value F5 of the support 11 from being separated from the backrest 4, so as to prevent the connector device 1 from being separated from the backrest 4 when it is pulled out.

[0184] The force values in the above embodiments need to satisfy F5>F2>F1>F4 and F1>F3, so that the connector device 1 will not be separated from the backrest during the process of being plugged in and pulled out, and the reliability of the first connector assembly 12 and the second connector assembly 13 during the matching and disconnection process is improved.

[0185] Please refer to FIG. 19 and FIG. 21, along the first direction Y, the support 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 opposite to the first opening 112a, and the second blocking part 113b is opposite to the first blocking part 112b. When it is needed to release the cooperation between the first connector assembly 12 and the second connector assembly 13 (for example, to disassemble the headrest), the second connector assembly 13 is pulled upward, so that the limiting assembly 14 can abut against the first blocking part 112b, and the first blocking part 112b limits 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 blocking of the first blocking part 112b, the cooperation between the first connector assembly 12 and the second connector assembly 13 is released, and meanwhile, the first connector assembly 12 is limited to disengage from the sliding channel 111.

[0186] As shown in FIG. 22, it is a schematic view of the first connector assembly 12 accidentally disengaging when the first connector assembly 12 cooperates with the second connector assembly 13, and the bottom 113 of the support 11 is provided with the second blocking part 113b. If the second connector assembly 13 is inserted rapidly, the impact force causes the first connector assembly 12 to disengage from the limiting area A before the first connector assembly 12 cooperates with the second connector assembly 13. At this time, the second blocking part 113b abuts against part of the limiting assembly 14, so as to block the limiting assembly 14 and the first connector assembly 12, and prevent the limiting assembly 14 and the first connector assembly 12 from falling to the backrest.

[0187] As shown in FIG. 23, it is a schematic view of the first connector assembly 12 cooperating with the second connector assembly 13 in the state shown in FIG. 22, and at this time, the second connector assembly 13 can cooperate with the first connector assembly 12 again under the blocking of the second blocking part 113b. Through the arrangement of the first blocking part 112b and the second blocking part 113b, the embodiment can realize the release of the cooperation between the first connector assembly 12 and the second connector assembly 13, and also can play a role of bidirectional anti-disengagement, so as to ensure the stability of the connector device 1.

Along the second direction X, the two ends of the elastic member 142 are connected with the two limiting members 141 respectively, and at least part of the two limiting members 141 can extend out of the shell 143. The elastic member 142 is used to provide a pushing force to the two limiting members 141 connected with the two ends of the elastic member 142, so that the two limiting members 141 can abut against the inner wall of the sliding channel 111.

[0189] As shown in FIG. 25, a schematic view of the limiting assembly 14 and the support 11 is shown. 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 pushing force to the two limiting members 141, so as to maintain the abutment of the limiting members 141 against the inner wall of the sliding channel 111, thereby realizing that the first connector assembly 12 stays at any position in the sliding channel 111.

[0190] In the above embodiments, the surface of the limiting member 141 in contact with the inner wall of the sliding channel 111 can be provided as an arc surface 141a, so as to improve the stability of the movement of the limiting member 141 along the inner wall of the sliding channel 111.

[0191] Further, please continue to refer to FIG. 25, the outer side wall of the shell 143 is provided with a sliding block 143a, and the inner side wall of the sliding channel 111 is provided with a sliding groove 111a. During the movement of the limiting assembly 14 along the sliding channel 111, the sliding block 143a and the sliding groove 111a are in sliding cooperation, so as to limit the movement track of the limiting assembly 14, thereby ensuring the stability of the movement of the first connector assembly 12 / the first connector assembly 12 and the second connector assembly 13 in the sliding channel 111.
