[0003] In related technologies, when the headrest contains electrical equipment such as speakers, the electrical equipment inside the headrest is usually electrically connected to the vehicle through electrical connectors such as quick-connect fittings. Under this configuration, when replacing the headrest, the electrical connectors must be disconnected / connected first, and then the corresponding operation on the headrest must be performed, which makes it inconvenient to disassemble and assemble the headrest.

[0011] Optionally, a locking structure is provided between the fixing member and the moving member, the locking structure comprising: Locking grooves are provided in multiple ways along the moving direction of the moving part, and all of them are provided on the moving part.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] With the development of technology and the increasing demands of consumers for automotive features, more and more cars are being equipped with headrest speakers. In order to meet the diverse needs of customers, car manufacturers usually offer different configurations for a single model, among which high-end headrests (which may include headrest speakers, headrest aromatherapy, headrest ventilation, etc.) are one of the optional features.

[0026] Specifically, this refers to a particular headrest in the vehicle. Customers can choose either a standard headrest (without speakers or other electrical equipment) or a higher-spec headrest. This places the following requirements on the vehicle: First, the headrest is replaceable to be compatible with different headrest configurations; Second, electrical interfaces are reserved in the seats. These interfaces are unused when the vehicle is equipped with low-spec headrests, but can provide electrical signals when high-spec headrests are installed. Based on the above requirements, in related technologies, when the headrest contains electrical equipment such as speakers, the electrical equipment inside the headrest is typically electrically connected to the vehicle via electrical connectors such as quick-connect fittings; for example, such as Figure 1 As shown, some high-end headrests 01 have electrical devices such as speakers inside. The wiring harness 03 extends from the headrest 01 fixing foot 02 (the headrest 01 fixing foot 02 is the part of the headrest 01 that connects to the seat back), and the end of the wiring harness 03 is connected to a male or female quick-connect connector.

[0027] For ease of description, the following example, using the installation of a headrest, will illustrate the drawbacks of the above setup method.

[0028] With the above setup, when replacing the headrest, the headrest's fixing feet cannot be directly inserted into the backrest due to the presence of the wiring harness and quick-connect connectors. It is usually necessary to disassemble the back of the seat, pass the wiring harness through, manually connect the quick-connect connectors, and then insert the headrest's fixing feet into the backrest to complete the structural connection and locking. In other words, with the above-mentioned technical setup, replacing the headrest requires first disconnecting / connecting the electrical connections before performing the corresponding operation on the headrest, making headrest installation and removal inconvenient.

[0029] In view of the problem of inconvenient disassembly and assembly of headrests in the above-mentioned related technologies, the present application provides a connecting component that simplifies the disassembly and assembly process of headrests while achieving electrical connection.

[0030] like Figures 2-4 As shown, the connection in this embodiment includes a fixed component 3 and a movable component 4.

[0031] The fastener 3 is fixedly connected to the backrest 1.

[0032] In an exemplary embodiment, the fastener 3 is a structural component independent of the seat back 1, which is welded or threaded to the frame of the seat back 1.

[0033] In an exemplary embodiment, the fastener 3 and the backrest 1 of the seat are an integral part, that is, the fastener 3 itself is part of the backrest 1 frame, and in addition to being used to connect the headrest 2, it also serves as a reinforcing structure for the backrest 1 frame.

[0034] The movable part 4 is disposed on the headrest 2. For example, one end of the movable part 4 is connected to the frame inside the headrest 2, and the other end extends to the outside of the headrest 2.

[0035] Furthermore, the movable part 4 can be movably connected to the fixed part 3. That is, the movable part 4 and the fixed part 3 have two states: connected and unconnected (i.e., the movable part 4 and the fixed part 3 can be detachably connected); and when the movable part 4 is connected to the fixed part 3, the movable part 4 can move relative to the fixed part 3.

[0036] Furthermore, the movable component 4 in this embodiment is provided with an electrical contact 8. The electrical contact 8 can be a conductive sheet (e.g., a metal sheet) or a conductive coating, etc.

[0037] The electrical contact 8 is electrically connected to the electrical equipment inside the headrest 2. In an exemplary embodiment, the electrical contact 8 and the electrical equipment inside the headrest 2 can be electrically connected via a wiring harness.

[0038] An electrical connector 5 is provided on the fixing member 3. The electrical connector 5 can be a spring pin, or it can be a conductive post, etc.

[0039] Furthermore, it should be noted that the electrical connector 5 is a structural component installed on the vehicle seat and capable of electrical connection to the power supply and control terminals. By electrically connecting the electrical connector 5 to the electrical contact 8, the electrical equipment inside the headrest 2 can be electrically connected to the vehicle's control terminals and power supply, thereby enabling the electrical equipment inside the headrest 2 to function normally.

[0040] Furthermore, the electrical connector 5 is positioned along the movement path of the electrical contact 8. That is, when the movable member 4 is connected to the fixed member 3, the electrical contact 8, which is mounted on the movable member 4, passes through the electrical connector 5 during the movement of the movable member 4 relative to the fixed member 3. Thus, through the movement of the movable member 4 relative to the fixed member 3, the electrical connector 5 and the electrical contact 8 can be electrically connected.

[0041] When the headrest 2 is installed or removed from the seat using the connecting assembly in this embodiment, the electrical connector 5 and the electrical contact 8 can be connected or disconnected as the moving part 4 moves relative to the fixed part 3. In other words, by moving the moving part 4 relative to the fixed part 3, the connecting assembly in this embodiment can simultaneously install the headrest 2 and connect the electrical connector 5 and the electrical contact 8, or simultaneously remove the headrest 2 and disconnect the electrical connector 5 and the electrical contact 8. Thus, since no additional electrical connection action is required, the installation and removal process of the headrest 2 can be effectively simplified, making it easier to replace the headrest 2.

[0042] In some embodiments, a locking structure is provided between the fixed member 3 and the movable member 4, which is used to indicate the movement of the movable member 4 relative to the fixed member 3.

[0043] In an exemplary embodiment, the locking structure can be a pin hole structure. For example, the movable member 4 has a first hole, and the fixed member 3 has a corresponding second hole. By moving the movable member 4 relative to the fixed member 3, the first hole can align with the second hole. The outer diameter of the locking pin corresponds to the diameters of the first and second holes, allowing the locking pin to pass through both holes simultaneously. In this embodiment, when the first and second holes are aligned, the movable member 4 moves to a preset position (i.e., a position that meets the head alignment requirements); at this time, controlling the locking pin to pass through both holes simultaneously achieves locking of the fixed member 3 and the movable member 4.

[0044] Furthermore, to ensure the reliability of the locking mechanism, the first hole can be designed as a threaded hole, allowing for threaded connection with the locking pin. This prevents the locking pin from accidentally falling off.

[0045] Of course, the above-mentioned pin hole structure is only an exemplary implementation of the locking structure, and this application is not limited to it. For example, the locking structure can also be a snap-locking structure, etc.

[0046] In some embodiments, such as Figures 2-4As shown, the fixing member 3 includes a first fixing part 301 and a second fixing part 302. Furthermore, the first fixing part 301 and the second fixing part 302 are arranged at intervals in the moving direction of the moving member 4, and both can be movably connected to the moving member 4. This arrangement helps to increase the amount of contact between the moving member 4 and the fixing member 3, thereby improving the reliability of the connection between the moving member 4 and the fixing member 3, and also helps to improve the connection accuracy.

[0047] In an exemplary embodiment, the fixing member 3 includes a fixing tube. In this embodiment, the first fixing part 301 and the second fixing part 302 are two fixing tubes spaced apart in the moving direction of the moving member 4, and the two fixing tubes are coaxially arranged. The moving member 4 is a connecting rod that can be inserted into the fixing tube. It is understood that, in order to facilitate the insertion of the connecting rod into the fixing tube, there is a certain gap between the connecting rod inserted into the fixing tube and the inner wall of the fixing tube. On this basis, if the axial length of the fixing member 3 is short, the headrest 2 is prone to large shaking when subjected to force after the moving member 4 is inserted into the fixing member 3. In this embodiment, two fixing tubes are spaced apart in the moving direction of the moving member 4. The two fixing tubes cooperate to limit the same connecting rod, which can effectively reduce the shaking amplitude of the connecting rod when subjected to force, thereby improving the connection accuracy of the headrest 2.

[0048] In some implementations, the fixing member 3 has a fixing hole, the extension direction of which is parallel to the movement direction of the moving member 4; and the moving member 4 is inserted into the fixing hole; the electrical contact 8 is located on the surface of the moving member 4; the electrical connector 5 extends from the outer surface of the fixing member 3 to the inner cavity of the fixing hole, and one end of the electrical connector 5 extending into the inner cavity has a conductive spring, which is used to abut against the surface of the moving member 4.

[0049] In this embodiment, a conductive spring is provided at the end of the electrical connector 5. Under the pressure of the moving member 4, the conductive spring is compressed. In this way, after the moving member 4 moves to the preset position, that is, when the headrest 2 is in the assembly position, the moving member 4 is relative to the fixed member 3. The moving member 4 presses the conductive spring. Under the elastic force of the conductive spring itself, its connection with the electrical contact 8 is more reliable, thereby improving the reliability of the electrical connection between the electrical connector 5 and the electrical contact 8.

[0050] Furthermore, based on the aforementioned fixing member 3 including the fixing hole, in some embodiments, a first sealing member is provided at both ends of the fixing hole, and the first sealing member is used for sealing connection between the moving member 4 and the fixing member 3; and, a second sealing member is provided between the electrical connector 5 and the fixing member 3 for sealing connection between the fixing member 3 and the electrical connector 5.

[0051] By setting the first and second sealing elements, the movable part 4, the fixed part 3, and the electrical connector 5 can cooperate to form a closed cavity. This prevents dust, water, etc. from entering the cavity, thereby ensuring the installation and operation of the electrical system and reducing safety hazards.

[0052] Understandably, in specific application scenarios, the headrest 2 of the seat needs to be height-adjustable to meet the needs of users of different heights.

[0053] Based on the above requirements, in some embodiments, the electrical contact 8 is configured as a conductive sheet, and multiple conductive sheets are provided in the moving direction of the moving member 4, so that when the moving member 4 moves to different positions relative to the fixed member 3, the electrical connector 5 and the electrical contact 8 can be electrically connected; and / or, the conductive sheet is elongated, and the extending direction of the conductive sheet is parallel to the moving direction of the moving member 4, so that when the moving member 4 moves to different positions relative to the fixed member 3, the electrical connector 5 and the electrical contact 8 can be electrically connected.

[0054] Since the movable part 4 is a connector set on the headrest 2 and the fixed part 3 is a connector set on the backrest 1, the headrest 2 has different heights when the movable part 4 moves to different positions relative to the fixed part 3. In this embodiment, the electrical connector 5 and the electrical contact 8 can be electrically connected when the movable part 4 moves to different positions relative to the fixed part 3. In this way, the electrical connector 5 and the electrical contact 8 will not be disconnected after the headrest 2 is height adjusted, which is beneficial to improving the user experience.

[0055] Furthermore, based on the aforementioned height-adjustable headrest 2, in some embodiments, the locking structure includes a locking groove 7 and a locking pin 6. Moreover, multiple locking grooves 7 are provided in the moving direction of the moving member 4, and all are located on the moving member 4; the locking pin 6 penetrates the fixing member 3 and can engage with the locking groove 7 to limit the movement of the moving member 4 relative to the fixing member 3; wherein, when the locking pin 6 engages with different locking grooves 7, the electrical connector 5 can be electrically connected to the electrical contact 8.

[0056] With this configuration, the locking structure can effectively lock the moving part 4 and the fixed part 3 when the headrest 2 is at different heights, which helps to improve the stability of the headrest 2 at different heights.

[0057] In some embodiments, the fixing member 3 includes a first fixing tube and a second fixing tube arranged side by side and spaced apart along the width direction of the backrest 1; the moving member 4 includes a first connecting rod and a second connecting rod, the first connecting rod being correspondingly arranged with the first fixing tube and being able to be inserted into the first fixing tube, and the second connecting rod being correspondingly arranged with the second fixing tube and being able to be inserted into the second fixing tube.

[0058] In this embodiment, a fixed tube is used as the fixing element 3, and a connecting rod is used as the moving element 4. This design is simple in structure and lightweight, which is beneficial for lightweight vehicle design. The fixed tube includes a first fixed tube and a second fixed tube arranged side-by-side. The connecting rod includes a first connecting rod corresponding to the first fixed tube and a second connecting rod corresponding to the second fixed tube. This improves the stability and reliability of the connection between the moving element 4 and the fixing element 3.

[0059] This application also provides a seat, which includes a body, a headrest 2, and a connecting component.

[0060] like Figure 1 As shown, the main body in this embodiment has a backrest 1, and the headrest 2 has electrical equipment inside. The main body and the headrest 2 are connected by a connecting component. This connecting component is the same as that in any of the above embodiments. It should be noted that, since the connecting component is the same as that in any of the above embodiments, the beneficial effects of the connecting component on the seat are detailed above, and will not be repeated here.

[0061] In addition, this application also discloses a vehicle that includes the seat described in the above embodiments. Similarly, since the vehicle includes the seat described in the above embodiments, and the seat includes the connecting component in any of the above embodiments, the beneficial effects of the connecting component on the vehicle are detailed above and will not be repeated here.

[0062] Furthermore, in some embodiments, the electrical equipment inside the headrest 2 includes speakers. This can significantly improve the sound quality inside the vehicle for the following reasons: When there are no speakers inside the headrest 2, the sound heard in the driver's seat mainly comes from three directions: the front main speaker, the left door speaker, and the right door speaker.

[0063] When a speaker is installed inside the headrest 2, the sound heard by the driver's seat comes not only from the aforementioned directions but also from the speaker inside the headrest 2. Multiple speakers, combined with the amplifier's advanced algorithms, provide users (especially those in the primary listening position) with a richer and more layered surround sound effect.

[0064] In addition, the speaker inside the headrest 2 can help develop more distinctive functions, such as: silent navigation function (only the driver can hear the navigation voice prompts, and other people in the car are not affected by the navigation prompts).

[0065] Furthermore, based on the speaker installed in the headrest 2, the number of speakers can be adaptively designed as needed. This application does not make a specific limitation in this regard. For example, the number of speakers can be one or two, etc.
