[0047] A seat, such as a car seat, generally includes a seat body and a headrest located above the backrest of the seat body to provide support for the head and neck of an occupant and / or driver, thereby improving user experience.

[0048] The embodiments of the present application disclose a connection structure, a headrest module, and a seat. Although a car seat is used as an example, the present application is not limited thereto and can also be used for other seats having a headrest rod and a seat headrest.

[0049] According to some embodiments of the present application, as shown in FIG. 4 , a seat 100 includes a seat body 30 and a headrest module 20 , which are connected via a connecting structure 10 .

[0050] As shown in FIG. 1 and FIG. 2 , in some embodiments, the connection structure 10 includes a guide sleeve 1 , a headrest rod 2 , and a magnetic connector assembly 3 .

[0051] The guide sleeve 1 is used to be disposed on the seat body 30 , and the guide sleeve 1 provides an accommodating space 11 .

[0052] The headrest rod 2 is accommodated in the accommodating space 11 of the guide sleeve 1 and can be guided to move along the extending direction of the guide sleeve 1. That is, the guide sleeve 1 here can guide the movement of the headrest rod 2.

[0053] The magnetic connector assembly 3 includes a male connector 31 and a female connector 32. One of the male connector 31 and the female connector 32 is used to connect to the guide sleeve 1, and the other is used to connect to the headrest rod 2. The male connector 31 and the female connector 32 can be detachably connected magnetically, and one of the male connector 31 and the female connector 32 is connected to the seat wiring harness 41, and the other is connected to the headrest wiring harness 42.

[0054] In some embodiments, as shown in Figures 1 and 2, the female connector 32 and the guide sleeve 1 are fixed to the seat body 30 as fixing parts of the connection structure 10 for the seat headrest, the male connector 31 and the female connector 32 can be magnetically detachably connected, and the male connector 31 and the headrest rod 2 are movable parts of the connection structure 10.

[0055] The male and female connectors here are similar in meaning to those used in electrical connectors. The male connector 31 is a plug with a pin, while the female connector 32 is a plug with a hole. The male connector 31 is fixedly connected to the headrest rod 2 as a movable part, while the female connector 32 is fixed to the seat body 30 with the guide sleeve 1 as a fixed part. This facilitates installation and disassembly. The principle is that during assembly, the guide sleeve 1 is generally fixed to the seat body 30, and then the headrest rod 2 is directly inserted into the guide sleeve 1 until the magnetic connector on the headrest rod connects with the magnetic connector on the seat body 30. The operator can generally feel the magnetic effect and hear the sound of magnetic collision, indicating that the connection is complete. Using a male connector makes installation easier.

[0056] In some embodiments, the male connector 31 and the female connector 32 form a snap-fit ​​connection. Such a fitting structure is simple and easy to assemble and disassemble.

[0057] 5 and 6 , in some embodiments, the specific structure for forming a snap-fit ​​connection can be that the male connector 31 includes a male connector housing 311, the female connector 32 includes a female connector housing 321, the male connector housing 311 is provided with a plurality of elastic snap-fit ​​pins 3111 on its periphery, and the female connector housing 321 is provided with snap-fit ​​connectors 3211 corresponding to the elastic snap-fit ​​pins 3111 on its periphery. When the male connector 31 is connected to the female connector 32, each elastic snap-fit ​​pin 3111 is correspondingly snap-fitted and connected to each snap-fit ​​connector 3211 to form a snap-fit ​​connection. The structure using the elastic snap-fit ​​pins 3111 and the snap-fit ​​connector 3211 provides elastic force feedback and audible feedback from the elastic snap-fit ​​during assembly, facilitating assembly.

[0058] As shown in FIG5 , in some embodiments, the specific structure of the male connector 31 and the female connector 32 may be that the male connector 31 includes a male connector housing 311, and a plurality of first connecting pins 312 with different radial positions are exposed on the outer surface of the male connector housing 311. The first connecting pins 312 are exposed on the outer surface of the male connector housing 311 at one end, and the other end is covered by the outer surface and is electrically connected to the headrest wiring harness 42. A first magnetic body 313 is also provided on the outer surface of the male connector housing 311 and is located around the plurality of first connecting pins 312. The female connector 32 includes a female connector housing 321, and a plurality of first connecting pins 312 are exposed on the outer surface of the male connector housing 311. The outer surface of the female connector housing 321 is exposed to a plurality of annular connectors 322 of varying radial dimensions. These annular connectors 322 of varying radial dimensions are electrically connected to first connecting pins 312 at different radial locations. For example, as shown in FIG5 , first connecting pin 3121 corresponds to annular connector 3221, first connecting pin 3122 corresponds to annular connector 3222, first connecting pin 3123 corresponds to annular connector 3223, and first connecting pin 3124 corresponds to annular connector 3224. The annular connector 322 may be a slot structure, similar to a common pin-and-slot electrical connection structure. One end of the annular connector 322, or the first connecting pin, is exposed on the outer surface of the female connector housing 321, and the other end is electrically connected to the seat wiring harness 41. A second magnetic body 323 is also disposed on the outer surface of the female connector housing 321, surrounding the annular connector 322. The first and second magnetic bodies 313, 323 are capable of mutually attracting and connecting. This advantageously allows for easy installation of the male connector 31 and the female connector 32, as they are connected to the annular connector via pins. This eliminates the need for specific alignment, requiring only that the first connecting pin 312 be positioned within the circumferential range of the annular connector 322. In some embodiments, the annular connector 322 is a full 360° circumferential ring, and both the first and second magnetic bodies 313 and 323 are also full 360° circumferential rings. This ensures that the first connecting pin 312 can connect to the annular connector 322 regardless of its circumferential position during assembly, further simplifying the installation process.

[0059] It can be understood that in some embodiments shown in Figure 5, the positions of the first connecting pin 312 and the annular connector 322 can be interchanged, that is, the annular connector 322 can be located at the male connector 31, and the first connecting pin 312 can be located at the female connector 32.

[0060] 6 , in other embodiments, the specific structure of the male connector 31 and the female connector 32 may be that the male connector 31 includes a male connector housing 311, and a plurality of second connectors 314 are exposed on the outer surface of the male connector housing 311. The second connecting pin or the second connector 314 is exposed on the outer surface of the male connector housing 311 at one end, and the other end is covered by the outer surface and electrically connected to the headrest wiring harness 42. A third magnetic body 315 and a fourth magnetic body 316 are also provided on the outer surface of the male connector housing 311, and are located outside the second connecting pin or the second connector 314. The magnetic poles of the third magnetic body 315 and the fourth magnetic body 316 are opposite, for example, the third magnetic body may be an S pole and the fourth magnetic body may be an N pole. The female connector 32 includes The female connector housing 321 has a plurality of second connecting pins 324 or second connectors exposed on its outer surface. The plurality of second connecting pins 324 are electrically connected to the second connectors 314, respectively. A second connecting pin 322 or second connector is exposed on the outer surface of the female connector housing 321 at one end and electrically connected to the seat wiring harness 41 at the other end. The female connector 32 also has a fifth magnetic body 325 and a sixth magnetic body 326. For example, the fifth magnetic body 325 may have an N pole and the sixth magnetic body 326 may have an S pole. When the connection structure 10 is in the correct installation position, the third magnetic body 315 and the fifth magnetic body 325 attract and connect, and the fourth magnetic body 316 and the sixth magnetic body 326 attract and connect. It will be understood that in some embodiments shown in FIG. 6 , the positions of the second connecting pins 324 or the second connector 314 can be interchanged, i.e., the second connecting pin 324 can be located on the male connector 31, while the second connector 314 can be located on the female connector 32. Unlike the embodiment shown in FIG5 that uses an annular connector 322, the embodiment shown in FIG6 uses a second connector 314 whose circumferential length range is much smaller than the annular connector 322. For example, in some embodiments shown in FIG6 , a single second connector 314 is a single slot that matches the size of a single second connection pin 324, that is, the size of the second connector 314 is only roughly the same as the size of a single second connection pin 324, which can be approximately regarded as a point connection, while the one shown in FIG5 can be approximately regarded as a line connection. It can be understood that the connection structure of the connector pins shown in FIG5 and FIG6 is similar to the pin and slot structure of the common electrical connection structure, which will not be repeated here. The embodiment shown in FIG6 has the effect of lowering the material cost compared to the embodiment shown in FIG5 , because the metal conductive area required to be laid on the connector is smaller.The fool-proof structure in which the third magnetic body 315 and the fifth magnetic body 325 are attracted and connected, and the fourth magnetic body 316 and the sixth magnetic body 326 are attracted and connected when the connection structure 10 is in the correct installation position can also ensure the reliability of assembly. When incorrect assembly occurs, for example, the fourth magnetic body 316 and the fifth magnetic body 325 will be close to each other and repel each other, so that the assembler will feel the repulsive force and realize the assembly error. In this way, a lower-cost connection structure 10 is achieved and the reliability and convenience of assembly are also ensured. 6 , in some embodiments, the third magnetic body 315 , the fourth magnetic body 316 , and the fifth magnetic body 325 and the sixth magnetic body 326 are all partially arc-shaped, and the circumferential range of the third magnetic body 315 and the fifth magnetic body 325 corresponds to a portion of the second connecting pin 324 or the second connecting body 314 , for example, the third magnetic body 315 and the fifth magnetic body 325 correspond to the second connecting pins 3241 and 3242 and the second connecting bodies 3141 and 3142 respectively, and the circumferential range of the fourth magnetic body 316 and the sixth magnetic body 326 corresponds to the remaining portion of the second connecting pin 324 or the second connecting body 314 , for example, the fourth magnetic body 316 and the sixth magnetic body 326 correspond to the second connecting pins 3243 and 3244 and the second connecting bodies 3143 and 3144 respectively.

[0061] As shown in FIG. 1 , the headrest rod 2 has a hollow structure 21 , and the headrest harness 42 is located inside the hollow structure 21 of the headrest rod 2 , so that the headrest harness 42 is easily routed and protected.

[0062] The headrest wiring harness and seat wiring harness here, as the name suggests, are the wiring harness located in the headrest and the wiring harness located in the seat body. The headrest wiring harness is generally connected to electrical appliances, while the seat wiring harness can be connected to a power supply. The headrest wiring harness 42 is connected to the seat wiring harness 41 through a magnetic connector assembly 3, which can supply power to electrical appliances and transmit control signals to the electrical appliances of the headrest.

[0063] In some embodiments, as shown in FIG2 , the headrest rod 2 and the magnetic connector assembly 3 are both located within the accommodation space defined by the guide sleeve 1. This allows for a compact structure and ease of assembly and disassembly. From the operator's perspective, the headrest rod 2 only needs to be inserted into the opening of the guide sleeve 1 into the accommodation space 11, with no other components interfering with the view.

[0064] In addition, in some embodiments, the inventors found that due to errors, one of the male connector 31 and the female connector 32 of the magnetic connector assembly 3 for connecting to the seat body 30 is elastically fitted and connected to the inner wall of the guide sleeve 1. As shown in the figure, the female connector 32 may be elastically fitted and connected to the inner wall of the guide sleeve 1. For example, the material of the female connector or the guide sleeve 1 may be a certain flexible material, so that the fitting connection structure between the two can allow a certain deformation amount, thereby avoiding the influence of error factors on the fitting connection between the two, so that the connection structure can be easier to disassemble and assemble.

[0065] As described above, the headrest module 20 can be replaced in the seat as a separate integral module, or sold as a separate accessory as a replaceable part to meet the user's personalized needs for different headrest functions.

[0066] As shown in Figures 1 to 3, the headrest module 20 may include a headrest body 201, a headrest rod, and a magnetic connector joint. The headrest body 201 is provided with an electrical appliance. The headrest rod 2 is used to set the headrest module 20 on the seat body 30. The headrest rod 2 has a hollow structure 21. The headrest wiring harness 42 connected to the electrical appliance is located inside the hollow structure 21 of the headrest rod 2; the magnetic connector joint is one of the male connector 31 or the female connector 32. The connector joint is provided on the headrest rod 2 and is connected to the headrest wiring harness 42. The connector joint can be detachably matched and connected with the other male connector 31 or the female connector 32 provided on the seat body 30 through magnetic attraction. Similar to the above content, take the headrest module 20 having the male connector 31 as an example.

[0067] As described above, a seat 100 employing the connection structure 10 and headrest module 20 described in the above embodiments has a guide sleeve 1 disposed on a seat body 30. One of the male connector 31 and the female connector 32 is connected to the seat body 30, while the other is used to connect to the headrest rod 2. The male connector 31 and the female connector 32 are magnetically detachably connected. One of the male connector 31 and the female connector 32 is connected to a seat wiring harness 41 located in the seat body 30, while the other is connected to a headrest wiring harness 42. The seat 100 includes a first configuration or a second configuration. In the first configuration, the male connector 31 and the female connector 32 are magnetically connected. In the second configuration, the male connector 31 and the female connector 32 are disconnected, and the headrest rod 2 of the headrest module 20 and the magnetic connector connected thereto can be moved relative to the guide sleeve 1 for removal from the seat body 30.

[0068] In summary, the beneficial effects of the connection structure, headrest module and seat introduced in the above embodiments include but are not limited to, through the coordinated action of the guide sleeve, the magnetic connector assembly and the headrest rod, a magnetic connector is set on one side of the headrest, and another corresponding magnetic connector is set on the seat body. In this way, the wiring harness of the electrical appliances of the headrest and the wiring harness of the seat body can be connected through a simple structure. When electrical inspection and maintenance of the electrical appliances of the headrest are required, it is only necessary to release the magnetic effect, which is convenient for operation. When the operation is completed, the headrest rod is reinstalled until the two magnetic connectors are connected, which improves the convenience of disassembling and assembling the wiring harness, thereby facilitating electrical inspection, maintenance and replacement of the entire headrest module to meet the user's personalized needs for different headrest functions.
