Description

A split-type power supply structure for a headrest and a vehicle Technical Field

[0001] This invention belongs to the field of vehicle parts technology, specifically relating to a split-type power-conducting structure for a headrest and a vehicle thereof. Background Technology

[0002] As people's demands for comfort and functionality continue to rise, headrests with integrated electrical appliances are widely used in vehicles, seats, and other similar applications. These appliances include, but are not limited to, music players, massagers, and tablets, providing users with diverse experiences. The internal electrical components of these headrests require a power source to function properly. Since headrests are typically pluggable and adjustable relative to the seat, directly connecting the internal appliances to the power source with a fixed cable would easily lead to wear and breakage during plugging and unplugging, affecting the normal operation of the appliances. Therefore, most headrests feature a separate power supply structure to address this issue.

[0003] The core design concept of the existing split-type power-conducting structure is as follows: multiple first conductive contacts are set on the outside of the headrest support rod, and each of the first conductive contacts is electrically connected to the electrical appliance inside the headrest; correspondingly, a conductive structure connected to the power supply is set inside the seat, and multiple second conductive contacts are set on the conductive structure, each corresponding to one of the first conductive contacts. By assembling the headrest support rod and the seat, the first conductive contacts and the second conductive contacts come into contact, thereby realizing the conduction between the power supply and the electrical appliance, and supplying power to the electrical appliance.

[0004] To ensure the conductivity stability between the first and second conductive contacts and prevent electrical appliances from malfunctioning due to poor contact, existing technologies typically employ elastic deformation of the second (or first) conductive contact to maintain a tight fit. However, in actual design and use, there is a technical challenge in balancing the elastic deformation: if the deformation is too large, the insertion and extraction forces during the connection between the first and second conductive contacts will be excessive, increasing the difficulty of assembling the headrest and potentially causing additional wear on the conductive contacts during insertion and extraction, thus shortening their lifespan; if the deformation is too small, while reducing the difficulty of insertion and extraction, the second (or first) conductive contact is prone to plastic deformation after repeated insertion and extraction, leading to a decrease in its elastic recovery ability and an inability to maintain a tight fit with the corresponding conductive contact. This results in poor contact and unstable power supply, severely affecting the normal use of the headrest appliance and reducing the user experience.

[0005] Therefore, in view of the problems of difficulty in insertion and removal and poor contact caused by unreasonable setting of elastic deformation in the existing headrest split power structure, there is an urgent need for a split power structure that can reasonably set the elastic structure and take into account both the convenience of insertion and removal and the conductivity stability, so as to solve the above-mentioned technical defects. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a split-type power-conducting structure for a headrest and a vehicle, in view of the current state of the prior art.

[0007] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a split-type power-conducting structure for a headrest is proposed. The headrest includes an internal electrical appliance and a plurality of first conductive contacts connected to the outside of the support rod of the headrest. The plurality of first conductive contacts are all electrically connected to the electrical appliance. The split-type power-conducting structure includes: a connecting base; a conductive connector, one end of which is used to connect to a power source, and the other end of the conductive connector is provided with a plurality of second conductive contacts corresponding one-to-one with the first conductive contacts. The plurality of second conductive contacts are arranged at intervals along the outer edge of the connecting base for contact-type connection with the first conductive contacts. The second conductive contact includes a connecting end and a abutting end. The connecting end is fixedly connected to the connecting base, and the abutting end is a movable end. When the second conductive contact abuts against the first conductive contact, the second conductive contact can generate elastic deformation so that the second conductive contact and the first conductive contact remain in tight contact.

[0008] In the aforementioned split-type power-conducting structure for a headrest, the connecting base includes an internal receiving cavity, and the second conductive contact further includes an arc-shaped segment for connecting the connecting end and the abutting end, at least partially extending into the receiving cavity for abutting against the first conductive contact.

[0009] In the aforementioned split-type power-conducting structure for a headrest, the connecting base is provided with connecting posts corresponding one-to-one with the second conductive contact, and the connecting end is provided with a connecting hole. When the second conductive contact is installed on the connecting base, the connecting post is inserted into the connecting hole to fix the second conductive contact on the connecting base.

[0010] In the aforementioned split-type power-conducting structure for a headrest, the connecting post and the connecting end are connected by welding.

[0011] In the aforementioned split-type power-conducting structure for a headrest, the connecting base is made of plastic, and the connecting post is fixed to the connecting base after being hot-melted and shaped, forming an integral structure with the connecting post and the connecting end.

[0012] In the aforementioned split-type energized structure for a headrest, the elastic deformation direction of the arc-shaped segment is perpendicular to the contact surface of the first conductive contact.

[0013] In the aforementioned split-type power-conducting structure for a headrest, a limiting groove is provided on the connecting seat, and the abutting end is inserted into the limiting groove and movably abuts against the two side walls of the limiting groove.

[0014] In the aforementioned split-type power-conducting structure for a headrest, the connecting base includes a main body and a connecting part, the second conductive contact is connected to the main body, and the connecting part is integrally formed with the main body.

[0015] In the aforementioned split-type power-conducting structure for a headrest, the connecting seat further includes a limiting portion located between the main body and the connecting portion, the limiting portion being formed by extending outward from the outer wall of the connection between the main body and the connecting portion.

[0016] In addition to solving the above-mentioned technical problems, the present invention also proposes a vehicle including the above-mentioned split-type power-conducting structure for a headrest.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) By setting up a connector and a conductive joint, and arranging the second conductive contact and the first conductive contact in a one-to-one correspondence and at intervals along the outer edge of the connector, precise alignment and reliable contact between the two are achieved, eliminating the need for additional alignment operations and significantly improving assembly convenience. At the same time, the second conductive contact adopts a structural design of "fixed connection end + elastic abutment end", which relies on elastic deformation to provide continuous contact pressure during contact, effectively ensuring conductive stability. By rationally designing this elastic structure, a good balance can be achieved between insertion and extraction force and contact reliability: it avoids damage to the contact due to excessive insertion and extraction force, and prevents poor contact due to insufficient deformation, thereby extending the service life of the energized structure, ensuring stable power supply to electrical appliances inside the headrest, and improving user experience.

[0019] (2) By setting a receiving cavity in the connecting seat to accommodate the insertion and assembly of the headrest support rod, the headrest and the energized structure are precisely positioned. At the same time, an arc-shaped segment is set between the connecting end and the abutting end of the second conductive contact, and the arc-shaped segment extends at least partially into the receiving cavity. When the headrest support rod is inserted into the receiving cavity, the arc-shaped segment can directly abut against the first conductive contact, further improving the accuracy of the contact connection. The structural design of the arc-shaped segment can optimize the elastic deformation performance of the second conductive contact, so that it produces uniform elastic deformation when squeezed, avoiding stress concentration that could lead to contact breakage. At the same time, it enhances the stability of the elastic force, making the abutting end and the first conductive contact abut more tightly, further improving the conductivity reliability. It also facilitates the installation and arrangement of the second conductive contact, making the overall structure more compact.

[0020] (3) By setting connecting posts corresponding one-to-one with the second conductive contacts on the connector base, and setting connecting holes at the connecting ends of the second conductive contacts, the initial positioning and fixing of the second conductive contacts on the connector base is achieved by using the plug-in cooperation of the connecting posts and connecting holes. This avoids positional displacement of the second conductive contacts during installation or plugging and unplugging, provides a foundation for subsequent fixed connection, and ensures the structural stability of the second conductive contacts after installation. This structure is simple in design and easy to process. It can accurately control the installation position of each second conductive contact, ensure its docking accuracy with the first conductive contact, avoid poor contact caused by contact misalignment, further improve the assembly accuracy and conductivity stability of the energized structure, and reduce processing and assembly costs.

Detailed Implementation

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0028] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0029] As shown in Figures 1 to 5, this solution mainly focuses on the specific construction of a split-type electrified structure 400 for a headrest and its application in vehicles. The vehicles may include automobiles, buses, trucks, and other means of transportation equipped with headrests.

[0030] The split-type power-conducting structure 400 includes: a connector 410 and a conductive connector 420.

[0031] Specifically, the headrest contains an electrical appliance (e.g., a music player), and its support rod 100 has multiple first conductive contacts 110 on its outer side. Wires are installed inside the support rod 100; one end of each wire is electrically connected to the music player, and the other end is electrically connected to the multiple first conductive contacts 110. The multiple first conductive contacts 110 can be fixed to the outer side of the support rod 100 via external connectors; the connection method between them and the support rod 100 is prior art and will not be described further here.

[0032] In one embodiment, the vehicle seat is provided with a guide sleeve 200 into which a headrest support rod 100 is inserted, and a connecting seat 410 is used to connect to the guide sleeve 200.

[0033] In another embodiment, the seat further includes a connecting sleeve 300, which is preferably fixedly connected to the seat frame; the guide sleeve 200 is installed on the connecting sleeve 300 by a snap-fit ​​method, and the connecting seat 410 is also fixed to the connecting sleeve 300 by a snap-fit ​​method.

[0034] One end of the conductive connector 420 is used to connect to a power source. In one embodiment, this end is provided with a terminal that can be quickly plugged into a power source; the other end of the conductive connector 420 is provided with a plurality of second conductive contacts 421, the number and position of which correspond one-to-one with the first conductive contacts 110. The plurality of second conductive contacts 421 are arranged at intervals along the outer edge of the connector 410 for contact-type electrical connection with the first conductive contacts 110.

[0035] In a preferred embodiment, the connector 410 has an approximately columnar structure, and a plurality of second conductive contacts 421 are distributed at equal angles around its axis.

[0036] Each second conductive contact 421 includes a connecting end 421a fixed to the connecting base 410 and a movable abutting end 421b, the abutting end 421b being the movable end. When the second conductive contact 421 contacts the first conductive contact 110, the second conductive contact 421 can undergo elastic deformation, thereby ensuring that the two maintain a tight and stable electrical contact.

[0037] This solution achieves precise alignment and reliable contact between the connector 410 and the conductive connector 420 by setting up a connector 410 and a conductive connector 420, and by arranging the second conductive contact 421 and the first conductive contact 110 in a one-to-one correspondence along the outer edge of the connector 410. This eliminates the need for additional alignment operations and significantly improves the ease of assembly.

[0038] Meanwhile, the second conductive contact 421 adopts a structural design of "fixed connection end 421a + elastic abutment end 421b". During contact, it relies on elastic deformation to provide continuous contact pressure, effectively ensuring conductive stability. By rationally designing this elastic structure, a good balance can be achieved between insertion and extraction force and contact reliability: it avoids damage to the contact due to excessive insertion and extraction force, and prevents poor contact due to insufficient deformation, thereby extending the service life of the energized structure, ensuring stable power supply to electrical appliances inside the headrest, and improving the user experience.

[0039] It is worth mentioning that the connector 410 includes an internal receiving cavity 411, and the second conductive contact 421 also includes an arc-shaped segment 421c for connecting the connecting end 421a and the abutting end 421b. At least a portion of the arc-shaped segment 421c extends into the receiving cavity 411 for abutting against the first conductive contact 110.

[0040] By providing a receiving cavity 411 within the connector 410 to accommodate the insertion and assembly of the headrest support rod 100, precise positioning of the headrest and the energized structure is achieved. Simultaneously, an arc-shaped segment 421c is provided between the connecting end 421a and the abutting end 421b of the second conductive contact 421, extending at least partially into the receiving cavity 411. When the headrest support rod 100 is inserted into the receiving cavity 411, the arc-shaped segment 421c can directly abut against the first conductive contact 110, further improving the accuracy of contact engagement. The structural design of the arc-shaped segment 421c optimizes the elastic deformation performance of the second conductive contact 421, causing it to undergo uniform elastic deformation when compressed, preventing stress concentration that could lead to contact breakage. It also enhances the stability of the elastic force, making the abutting end 421b and the first conductive contact 110 more tightly abutted, further improving conductive reliability. Furthermore, it facilitates the installation and arrangement of the second conductive contact 421, making the overall structure more compact.

[0041] Furthermore, the connector 410 is provided with a connecting post 412 corresponding to the second conductive contact 421, and the connecting end 421a is provided with a connecting hole. When the second conductive contact 421 is installed on the connector 410, the connecting post 412 is inserted into the connecting hole to fix the second conductive contact 421 on the connector 410.

[0042] By setting connecting posts 412 on the connector 410 that correspond one-to-one with the second conductive contact 421, and setting connecting holes at the connecting ends 421a of the second conductive contact 421, the initial positioning and fixing of the second conductive contact 421 on the connector 410 is achieved by using the insertion and engagement of the connecting posts 412 and the connecting holes. This prevents the second conductive contact 421 from shifting position during installation or insertion / removal, provides a foundation for subsequent fixed connection, and ensures the structural stability of the second conductive contact 421 after installation.

[0043] The structure is simple in design and easy to manufacture. It can precisely control the installation position of each second conductive contact 421, ensuring its docking accuracy with the first conductive contact 110, avoiding poor contact caused by contact misalignment, further improving the assembly accuracy and conductivity stability of the energized structure, and reducing processing and assembly costs.

[0044] In one embodiment, the connecting post 412 is connected to the connecting end 421a by welding.

[0045] The connecting post 412 is fixedly connected to the connecting end 421a of the second conductive contact 421 by welding, so that the two form a strong integrated structure, which greatly improves the connection strength and effectively prevents the connecting end 421a from separating from the connecting post 412 due to force during the insertion and removal of the second conductive contact 421, thus ensuring the installation stability and structural reliability of the second conductive contact 421.

[0046] Meanwhile, the welded connection has good sealing performance, which can prevent dust, moisture and other impurities from entering the connection part 416, avoid impurities from affecting the conductivity of the contacts, and prevent short circuits or poor contact. It is suitable for scenarios with high requirements for connection strength and conductivity reliability, and further extends the service life of the energized structure.

[0047] In another embodiment, the connector 410 is made of plastic, and the connector 412 is hot-melt shaped to fix the connector end 421a to the connector 410. The hot-melt fixed connector 412 and the connector end 421a form an integral structure.

[0048] The connector 410 is made of plastic, which offers advantages such as easy processing, low cost, and good insulation, preventing short circuits caused by conductivity issues and improving the safety of the energized structure. Simultaneously, the connecting post 412 is integrally formed with the connector 410, and the connecting end 421a is fixed to the connector 410 via hot-melt molding. This creates a single, robust connection between the hot-melt connecting post 412 and the connecting end 421a, eliminating the need for additional welding equipment and processes. This simplifies processing and assembly, reduces production costs, and is suitable for large-scale production. This fixing method is convenient to operate and ensures the stability of the second conductive contact 421 after installation, preventing loosening during insertion and removal, thus balancing safety, stability, and economy.

[0049] Furthermore, the elastic deformation direction of the arc segment 421c is perpendicular to the contact surface of the first conductive contact 110.

[0050] The elastic deformation direction of the arc segment 421c is set to be perpendicular to the contact surface of the first conductive contact 110, so that the squeezing force on the arc segment 421c is consistent with the elastic deformation direction, ensuring that the elastic deformation is uniform and the elastic force can be accurately applied to the contact part between the first conductive contact 110 and the second conductive contact 421, further improving the tightness of the contact between the two and avoiding unstable power supply caused by contact gaps.

[0051] Meanwhile, this design can prevent the second conductive contact 421 from being misaligned or offset from the first conductive contact 110 due to the deformation direction deviation of the arc segment 421c, ensuring that the contacts are always accurately aligned, effectively avoiding poor contact caused by unreasonable deformation direction, further improving the conductivity stability and reliability of the energized structure, and extending the service life of the contacts.

[0052] The connecting seat 410 is provided with a limiting groove 413, and the abutting end 421b is inserted into the limiting groove 413 and moves against the two side walls of the limiting groove 413.

[0053] By setting a limiting groove 413 on the connector 410, the abutting end 421b of the second conductive contact 421 is inserted into the limiting groove 413 and moves against the two side walls of the limiting groove 413, thereby limiting the abutting end 421b and preventing the second conductive contact 421 from shifting or tilting during elastic deformation. This ensures that the abutting end 421b always maintains precise alignment with the first conductive contact 110, preventing poor contact caused by contact shift.

[0054] Meanwhile, the limiting groove 413 can disperse the squeezing force on the abutment end 421b, preventing damage or deformation of the abutment end 421b due to concentrated force, and extending the service life of the second conductive contact 421. In addition, the limiting groove 413 can also guide the abutment end 421b to move along the elastic deformation direction, ensuring the rationality of elastic deformation, further balancing the convenience of insertion and removal with conductive stability, and improving the overall reliability of the energized structure.

[0055] The connector 410 includes a main body 414 and a connecting part 416. The second conductive contact 421 is connected to the main body 414, and the connecting part 416 is integrally formed with the main body 414.

[0056] The connector 410 is divided into a main body 414 and a connecting part 416. The main body 414 is used to install the second conductive contact 421, and the connecting part 416 is used to fix and connect with an external structure (such as a connecting sleeve 300). The division of labor is clear, which facilitates the installation and arrangement of the second conductive contact 421 and the overall assembly of the connector 410, and improves the ease of assembly.

[0057] Meanwhile, the connecting part 416 is integrally formed with the main body 414, which greatly improves the overall structural strength of the connector 410 and avoids problems such as loosening or breakage between the main body 414 and the connecting part 416. This ensures that the connector 410 can stably support the second conductive contact 421 and avoids contact misalignment or poor contact caused by looseness of the connector 410 structure. The integrally formed structure also simplifies the processing technology, reduces processing costs, reduces assembly steps, and improves assembly efficiency. At the same time, it makes the overall structure of the connector 410 more compact, adapting to the assembly requirements of the headrest and further improving the overall stability of the power-conducting structure.

[0058] The connecting seat 410 also includes a limiting part 415 located between the main body part 414 and the connecting part 416, the limiting part 415 being formed by extending outward from the outer wall of the connection between the main body part 414 and the connecting part 416.

[0059] By providing a limiting part 415 between the main body 414 and the connecting part 416, the limiting part 415 extends outward from the outer wall of the connection between the two. When the connecting seat 410 is installed to an external structure (such as the connecting sleeve 300) through the connecting part 416, the limiting part 415 can abut against the corresponding part of the connecting sleeve 300, thereby limiting the connecting seat 410 and preventing the connecting seat 410 from being over-inserted into the external structure, which would result in overly tight installation. This facilitates the installation and disassembly of the connecting seat 410 and improves assembly convenience.

[0060] Meanwhile, the limiting part 415 ensures the accurate positioning of the connector 410 after installation, preventing misalignment and poor contact between the second conductive contact 421 and the first conductive contact 110 due to misalignment of the connector 410, thus further improving the accuracy and conductivity stability of the contact connection. Furthermore, the limiting part 415 also enhances the structural strength of the connection between the main body 414 and the connecting part 416, preventing damage to this area due to concentrated stress, further improving the overall structural reliability and service life of the connector 410.

[0061] This solution also proposes a vehicle including the aforementioned split-type electrification structure 400.

[0062] In summary, the split-type power-conducting structure 400 for headrests and the vehicles containing this structure address the core pain points of the split-type power-conducting structure 400 for headrests in the background technology, such as difficulty in insertion and removal, poor contact, unstable fixing of conductive contacts, and low assembly precision. Through layer-by-layer optimized technical design, multiple technical improvements have been achieved.

[0063] The core design optimizes the structure of the second conductive contact 421 (design of the connecting end 421a, abutting end 421b, and arc segment 421c) to reasonably control elastic deformation, balancing ease of insertion and removal with conductive stability. The installation stability and assembly precision of the conductive contact are improved through the cooperation of the connecting post 412 and the connecting hole, and by welding or hot-melt fixing. The overall assembly positioning effect is further optimized through structures such as the receiving cavity 411, limiting groove 413, and limiting part 415, avoiding problems such as contact misalignment and structural loosening. The design of the plastic connecting seat 410 and the integrated molding structure balances safety, economy, and structural strength. Overall, this split-type power supply structure 400 solves many defects of the prior art, can stably supply power to headrest electrical appliances, extend service life, reduce processing and maintenance costs, and is suitable for various headrest application scenarios, especially vehicle headrests. It can effectively improve user experience and product market competitiveness.
