[0043] IDFSHA24155&250447 2CNCN chair 1, in order to at least partially solve the above technical problems.

[0044] It can be understood that the connecting structure 10 provided by the present application is especially suitable for automotive seats, but is not limited thereto, and can also be applied to other applicable occasions, such as seats of other vehicles, cinema seats, massage chairs, etc.

[0045] Referring to Figures 1 to 6 The present application provides a connecting structure 10 between the headrest 20 and the seat back 30 of the seat 1, which comprises: a headrest rod 110 for connecting the headrest 20 and provided with a locking groove 111; a locking mechanism 120 for connecting the seat back 30, comprising: a guide bracket 1210, a moving plate 1220, a lock tongue piece 123, and a driving piece 124; wherein the guide bracket 1210 is provided with a sliding groove 1211 and a guide sleeve 1212 for accommodating the headrest rod 110; the moving plate 1220 is movably connected to the sliding groove 1211; the lock tongue piece 123 is connected to the moving plate 1220 and can contact the headrest rod 110; the driving piece 124 is connected to the moving plate 1220; the headrest rod 110 can move along the guide sleeve 1212; the lock tongue piece 123 can be connected to the locking groove 111 in a matching manner and lock the headrest 20 and the seat back 30; the driving piece 124 can drive the moving plate 1220 to move the lock tongue piece 123 away from the locking groove 111 and unlock the headrest 20 and the seat back 30.

[0046] As Figures 2 to 4As shown, the headrest rod 110, the guide sleeve 1212, and the locking tongue 123 are generally in two sets, but are not limited thereto; the driving component 124 can be manual or electric, and can drive the moving plate 1220 to move along the slide groove 1211. For example, the driving component 123 can be a linkage mechanism or other transmission mechanism, but is not limited thereto; preferably, the guide bracket 1210 is connected to the backrest bracket 31 inside the backrest 30; the backrest bracket 31 may also be connected to... The linear movement mechanism 32 of the guide bracket 1210 is used to adjust the height of the headrest 20 and the connecting structure 10, etc.; the guide sleeve 1212 has a certain length to guide the movement of the headrest rod 110; preferably, the extension direction of the slide groove 1211 is set to be perpendicular to the extension direction of the guide sleeve 1212, so as to make the layout compact; preferably, the connecting structure 10, including the headrest rod 110, can be completely accommodated inside the chair back 30, such as Figure 1 As shown, this makes the appearance simple and beautiful.

[0047] Since the headrest rod 110, the guide sleeve 1212, and the locking tongue 123 are generally in two sets, some comparative solutions require two-hand operation to unlock the headrest. However, this application...

[0048] The design of using the drive component 124 to drive the moving plate 1220 is more conducive to one-handed operation and is simpler and faster. Compared with the traditional headrest connection structure, the connection structure 10 provided in this application makes the installation and removal of the headrest 20 more convenient and faster. It also features simplified parts, a compact overall layout, light weight, and low cost.

In this way, the male connector 131 and the female connector 132 can be automatically aligned and attracted, etc., while ensuring reliable line connection, which is convenient to operate.

[0061] In one or more embodiments of the connection structure 10, the electrical connector 130 is a floating type electrical connector. The term "floating type electrical connector" is similar in meaning to the commonly understood floating connector by those of ordinary skill in the art, that is, a connector that allows the male connector 131 and the female connector 132 to move out of position in the direction of insertion and removal or in a direction perpendicular to the direction when connected. For example, the female connector 132 can be elastically connected to the guide sleeve 1212. In this way, it is beneficial to automatically correct the positional deviation between the male connector 131 and the female connector 132 when connecting and disconnecting the electrical connector 130, which is easy to operate, reliable in connection, and also beneficial to improve impact resistance, vibration resistance, and prolong service life, etc.
