DETAILED DESCRIPTION

[0024] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] In the description of the present application, it should be noted that directional words, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of narrating the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and cannot be understood as limiting the specific scope of protection of the present application.

[0026] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0027] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0028] As a preferred embodiment, see Figures 1 to 6The present application provides an electrically adjustable four-way headrest mechanism 1, comprising: a headrest mounting member 10, one end of the headrest mounting member 10 is externally connected to the headrest; a headrest moving member 20, the other end of the headrest mounting member 10 is connected to the headrest moving member 20, the headrest moving member 20 is provided with a first motor 21, the first motor 21 and the headrest mounting member 10 are arranged on opposite sides of the headrest moving member 20, the first motor 21 drives the headrest moving member 20 to move and adjust along a first direction X1; a first mounting platform 30, the first mounting platform 30 is connected to the headrest moving member 20, and the first mounting platform 30 is arranged toward one side of the headrest mounting member 10, the first mounting platform 30 is provided with a second motor 31, the second motor 31 drives the headrest mounting member 10 to move and adjust toward a second direction X2; wherein, the second direction X2 is a direction away from or close to the headrest moving member 20, and the first direction X1 and the second direction X2 are perpendicular to each other.

[0029] Specifically, see Figure 3 , taking the four-way headrest mechanism 1 as a reference when it is vertically set, the first direction X1 is vertically downward or upward along the direction of gravity, that is, the headrest moving part 20 moves upward or downward along the first direction X1, and the second direction X2 is perpendicular to the first direction X1. Therefore, the headrest mounting part 10 moves left or right along the horizontal direction relative to the headrest moving part 20 to adjust, thereby realizing the four-way adjustment of the four-way headrest mechanism 1 in the present application document.

[0030] As a preferred embodiment, the headrest moving member 20 includes: a headrest moving panel 22 and a headrest support rod 23, the headrest moving panel 22 is connected to the headrest mounting member 10, and the headrest moving panel 22 is movably connected to the headrest support rod 23. It should be noted that the horizontal position adjustment or vertical position adjustment of the four-way headrest mechanism 1 in the present application document is all achieved by electric adjustment. The electrically adjustable four-way headrest mechanism 1 has the advantage of labor-saving adjustment. However, since a motor is required to drive the four-way headrest mechanism 1 to a certain extent, the electrically adjustable headrest mechanism in the related art has a relatively complex structure and the motor setting position is relatively unreasonable, and cannot be effectively applied to the seats of actual vehicles. Therefore, the four-way headrest mechanism 1 provided in the present application document, similarly, the vertical position adjustment of the headrest moving part 20 requires the drive of the first motor 21, so the first motor 21 is arranged on the headrest moving part 20. Preferably, the first motor 21 is specifically arranged on the headrest moving panel 22, and the first motor 21 drives the headrest moving panel 22 to move relative to the headrest support rod 23. At the same time, the first motor 21 is arranged on the side of the headrest driving panel to effectively increase the vertical movement range of the headrest moving panel 22 relative to the headrest support rod 23, and increase the upward and downward adjustable range of the headrest moving panel 22.

[0031] Preferably, the shell of the first motor 21 and the headrest motion panel 22 are integrally formed by injection molding. Since the movement adjustment of the headrest motion panel 22 relative to the headrest support rod 23 is a relatively fine distance adjustment, the first motor 21 is required to have a relatively stable operating environment. The shell of the first motor 21 and the headrest panel that are integrally formed can ensure the stability of the first motor 21 relative to the headrest motion panel 22 during operation, so as to ensure the adjustment accuracy of the headrest motion panel 22 relative to the headrest support rod 23.

[0032] The headrest mounting member 10 is used for an external automobile headrest, that is, the part against which the user's head rests. The operation adjustment trajectory of the headrest mounting member 10 is to adjust left and right in the horizontal direction relative to the headrest moving member 20. The headrest mounting member 10 is driven by a second motor 31, and a first mounting platform 30 is provided through the headrest moving panel 22. The first mounting platform 30 is a plate-like structure. The first mounting platform 30 and the first motor 21 are located on opposite sides of the headrest moving panel 22, and the second motor 31 is assembled on the first mounting platform 30. The setting of the first mounting platform 30 further improves the assembly stability of the second motor 31 relative to the headrest moving panel 22, reduces the operation shaking of the second motor 31, and avoids the overhead setting of the second motor 31.

[0033] Furthermore, since the second motor 31 needs to drive the headrest mounting component 10, the second motor 31 is arranged at the top of the headrest mounting component 10 in conjunction with the first mounting platform 30. At the same time, the first mounting platform 30 is arranged close to the headrest mounting component 10. The setting shape of the first mounting platform 30 corresponds to the cross-sectional shape of the headrest mounting component 10 to ensure that the structure of the four-way headrest mechanism 1 is reasonable and compact, saving assembly space.

[0034] As another preferred embodiment, see Figure 2 The headrest support rod 23 includes: a first headrest support rod 231, a second headrest support rod 232 and a bracket connecting rod 233. The first headrest support rod 231 and the second headrest support rod 232 are parallel to each other, and the first headrest support rod 231 and the second headrest support rod 232 are arranged through the headrest movement panel 22. One end of the bracket connecting rod 233 is connected to the end of the first headrest support rod 231, and the other end of the bracket connecting rod 233 is connected to the end of the second headrest support rod 232; wherein the first motor 21 is provided with a first driving rod 211, one end of the first driving rod 211 is connected to the bracket connecting rod 233, and the first driving rod 211 is driven to rotate by the first motor 21, thereby driving the headrest movement surface to move with the extension direction of the first headrest support rod 231 and the second headrest support rod 232 as the track.

[0035] The first headrest support rod 231 and the second headrest support rod 232 realize the function of supporting and providing a running track. The headrest motion panel 22 is sleeved on the first headrest support rod 231 and the second headrest support rod 232, and runs and adjusts along the extension direction of the first headrest support rod 231 and the second headrest support rod 232.

[0036] The present application document has a support rod 233 sandwiched between the first headrest support rod 231 and the second headrest support rod 232. The support rod 233 is not limited to a rod-shaped structure in a specific embodiment. The support rod 233 in the present application document is a bridge-type plate body, and the two ends of the bridge-type plate body connect the first headrest support rod 231 and the second headrest support rod 232 to improve the stability of the first headrest support rod 231 and the second headrest support rod 232. At the same time, the bridge-type plate body is used to be fixedly connected to one end of the first drive rod 211, and then the first drive rod 211 is a rod body with an external thread, and the first motor 21 moves up and down relative to the external thread of the first drive rod 211, thereby driving the headrest mounting panel 11 to move up and down relative to the first headrest support rod 231 and the second headrest support rod 232.

[0037] Further preferably, the electrically adjustable four-way headrest mechanism 1 also includes: a drive line 40, which is a circuit connecting line used for an external power supply to drive the first motor 21 and the second motor 31 to operate. The drive line 40 takes the first headrest support rod 231 as an entry end, passes through the first headrest support rod 231 and is led out, and then the drive line 40 extends to the middle of the support rod 233 in contact with the bracket connecting rod 233, and then branches out. One end of the drive line 40 is connected to the second motor 31 to complete the circuit conduction, and the other end of the drive line 40 is connected to the first motor 21 to complete the circuit conduction.

[0038] Specifically, the bracket connecting rod 233 of the bridge-type plate structure is also provided with an end groove, which facilitates the driving line 40 to fit the bracket connecting rod 233 of the bridge-type plate structure for routing, thereby optimizing the arrangement of the driving line 40, ensuring the rationality of the routing of the four-way headrest mechanism 1 in the present application document, so that the four-way headrest mechanism 1 in the present application document only needs to introduce one driving line 40 to complete the driving of the first motor 21 and the second motor 31. At the same time, the routing of the driving line 40 always fits the second headrest support rod 232 and the bracket connecting rod 233, avoiding the phenomenon of flying wires and messy wires, improving the overall compactness of the four-way headrest mechanism 1, and making the four-way headrest mechanism 1 in the present application document more suitable for actual assembly with seats.

[0039] Further preferably, the headrest motion panel 22 is integrally injection molded, that is, the first motor 21 housing and the first mounting platform 30 provided on the headrest motion panel 22 are integrally injection molded to ensure that the overall headrest motion panel 22 has high consistency and strength.

[0040] Further preferably, a grille grid structure 50 is distributed on the panel surface of the headrest motion panel 22, wherein the front panel, side panel and bottom panel of the headrest motion panel 22 are all distributed with the grille grid structure 50. The provision of the grille grid structure 50 increases the weight of the headrest motion panel 22 while ensuring that the headrest motion panel 22 has a higher strength as a whole, thereby making the movement and adjustment of the headrest motion panel 22 more labor-saving during the actual adjustment process.

[0041] Further preferably, the headrest mounting member 10 includes: a headrest mounting panel 11, the headrest mounting panel 11 is used for an external headrest; a first connecting rod 12 and a second connecting rod 13, the first connecting rod 12 and the second connecting rod 13 are staggered, and a rotating shaft is provided at the staggered position to link the first connecting rod 12 and the second connecting rod 13, the first connecting rod 12 and the second connecting rod 13 both include a fixed end and a movable end, the fixed end of the first connecting rod 12 is fixedly connected to the headrest mounting panel 11, the movable end of the first connecting rod 12 is movably connected to the headrest moving part 20, the fixed end of the second connecting rod 13 is fixedly connected to the headrest moving part 20, and the movable end of the second connecting rod 13 is movably connected to the headrest mounting panel 11; wherein, by moving the movable end of the first connecting rod 12 to the headrest moving part 20, cooperating with the same movement of the movable end of the second connecting rod 13 to the headrest mounting panel 11, the movement and adjustment of the headrest mounting panel 11 along the second direction X2 is realized.

[0042] Furthermore, the second motor 31 is provided with a second driving rod 311 , which is connected to the moving end of the first connecting rod 12 . The second driving rod 311 drives the moving end of the first connecting rod 12 to move, and the moving end of the second connecting rod 13 moves along with the moving end of the first connecting rod 12 .

[0043] Further, the headrest moving part 20 is provided with a first sliding groove 60, specifically, the headrest moving panel 22 is provided with a first sliding groove 60, and the headrest mounting panel 11 is provided with a second sliding groove 61. In one embodiment, preferably, the first sliding groove 60 is integrally formed with the headrest moving panel 22, and the second sliding groove 61 is integrally formed with the headrest mounting panel 11. The moving end of the first connecting rod 12 is provided with a first slider 121, and the moving end of the second connecting rod 13 is provided with a second slider 131. The first slider 121 is located in the first sliding groove 60, and the second slider 131 is located in the second sliding groove 61. The second driving rod 311 is fixedly connected to the first slider 121, wherein the second driving rod 311 drives the first slider 121 to slide in the first sliding groove 60, and then drives the second slider 131 to slide in the second sliding groove 61 in the same direction as the first slider 121.

[0044] Furthermore, the second driving rod 311 is built into the first sliding groove 60. The second driving rod 311 is built-in to avoid being exposed to the outside. Through the protection of the first sliding groove 60, the influence of dust on the operation of the second driving rod 311 is reduced, thereby increasing the service life of the second driving rod 311.

[0045] Specifically, see Figure 3 The movement and adjustment of the headrest mounting panel 11 relative to the headrest movable panel is achieved by the second motor 31 driving the movement of the first connecting rod 12 and the second connecting rod 13, wherein the fixed end of the first connecting rod 12 is fixed in the second sliding groove 61 through the first fixing block 14, and the fixed end of the first connecting rod 12 is set in the first sliding groove 60 through the second fixing block 15, and the fixed end of the first connecting rod 12 and the fixed end of the second connecting rod 13 are arranged at the same level, and Figure 3 What is shown is a schematic diagram of the headrest mounting panel 11 in a folded state relative to the headrest movable panel. Since the first connecting rod 12 and the second connecting rod 13 are arranged in an X-shape and a fixed shaft is interspersed at the midpoint of the staggered arrangement, when the first slider 121 is located in the first sliding groove 60 and moves close to the second fixed block 15, it will drive the second slider 131 located in the second sliding groove 61 and move close to the first fixed block 14, and then the moving end of the first connecting rod 12 gradually approaches the fixed end of the second connecting rod 13, and the moving end of the second connecting rod 13 gradually approaches the fixed end of the first connecting rod 12, thereby completing the unfolding movement adjustment of the headrest mounting panel 11 relative to the headrest movable panel.

[0046] Furthermore, in the actual installation process of the four-way headrest mechanism 1 in the present application document, the actual main components of the four-way headrest mechanism 1 only include the headrest moving part 20 and the headrest mounting part 10, with fewer components and convenient assembly.

[0047] It should be noted that during the installation process, after the through hole of the headrest motion panel 22 passes through the first headrest support rod 231 and the second headrest support rod 232, the two ends of the bracket connecting rod 233 are fixedly connected to the first headrest support rod 231 and the second headrest support rod 232 respectively. The first motor 21 is pre-installed with the first drive rod 211, so only one end of the first drive rod 211 needs to be fixedly connected to the bracket.

[0048] When assembling the headrest motion panel 22 and the headrest mounting panel 11, it is necessary to first connect the fixed end of the first link 12 to the first fixed block 14 in a rotatable manner through a rotating shaft, and at the same time connect the movable end of the second link 13 to the second slider 131 in a rotatable manner through a rotating shaft. One end of the second sliding groove 61 is closed, and the other end is provided with an opening. The second slider 131 is inserted from the end of the second sliding groove 61 with the opening, thereby completing the installation of the first link 12 and the second link 13 relative to the headrest mounting panel 11. It should be noted that the rod length of the first link 12 and the second link 13 is less than the groove length of the second sliding groove 61, so as to prevent the second slider from falling out of the second sliding groove 61. Then, the guide sleeve 16 provided on the headrest mounting panel 11 is inserted into the headrest motion panel 22. The provision of the guide sleeve 16 can further improve the stability of the headrest mounting panel 11 when it moves horizontally relative to the headrest motion panel 22.

[0049] Further, see Figure 5 , it is necessary to first push the first sliding block into the bottom opening of the first sliding groove 60, and then encapsulate the second fixing block 15 at the bottom opening of the first sliding groove 60, and a trapezoidal interlocking hole 62 is provided at the bottom opening of the first sliding groove 60, and the second fixing block 15 is fixedly connected to the bottom opening of the first sliding groove 60 through the interlocking hole 62. At the same time, when the second fixing block 15 needs to be disassembled, it is only necessary to unscrew the screws in the screw holes on both sides of the trapezoidal interlocking hole 62. Through the guiding effect of the trapezoidal interlocking hole 62, the second fixing block 15 can be removed from the bottom opening of the first sliding groove 60 with less effort, thereby reducing the difficulty of assembling and disassembling the second fixing block 15 relative to the first sliding groove 60. When the first sliding block and the second fixed block 15 are installed in place, it is only necessary to connect the movable end of the first connecting rod 12 to the first sliding block 121 in a rotatable manner via a rotating shaft, and the fixed end of the second connecting rod 13 to the second fixed block 15 in a rotatable manner via a rotating shaft. Therefore, the assembly between the headrest moving part 20 and the headrest mounting part 10 in the present application document is feasible, and the installation method and installation process are relatively convenient, and the compatibility with the actual car seat is relatively high.
