Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, and in particular to a quick-installation structure for a seat headrest. Background Technology

[0002] In the field of automotive seat technology, headrests are an important component, not only providing support for passengers' heads but also playing a crucial role in protecting passengers' necks and reducing injuries during vehicle collisions. The installation structure of the headrest directly affects its convenience, stability, and ease of subsequent maintenance.

[0003] Traditional chair headrests typically employ a complex installation structure to connect the headrest body to the backrest frame. This traditional installation structure often involves multiple components, using a combination of various connection methods (such as bolt connections, snap-fit ​​connections, etc.) to gradually fix the headrest body to the backrest frame. When repair, replacement, or cleaning of the headrest body is required, the diverse and tight connections between the headrest body and the backrest frame necessitate disassembly by sequentially disconnecting each connection point in a specific order. This often requires specialized tools, and the limited operating space increases the difficulty and time required for disassembly. Utility Model Content

[0004] In view of the problems existing in the prior art, the present invention aims to provide a quick-installation structure for a seat headrest that is simple in structure and highly stable, which can achieve quick assembly and disassembly of the headrest body without the aid of tools.

[0005] To achieve the above objectives, this utility model proposes a quick-installation structure for a seat headrest, including a headrest assembly and a backrest frame. The headrest assembly includes a headrest rod, a headrest back cover, a headrest support, and a headrest body. The lower end of the headrest rod is welded to the backrest frame, and a sheet metal bracket is welded to the upper end of the headrest rod. A steel wire bracket is provided below the sheet metal bracket, and the steel wire bracket is welded to the backrest frame and / or the headrest rod. The headrest back cover covers the rear side of the headrest rod, with its upper front end fixedly connected to the sheet metal bracket and its lower front end fixedly connected to the steel wire bracket. The headrest support covers the front of the headrest back cover, with its lower end snapped onto the steel wire bracket and its upper end fixed to the sheet metal bracket. The headrest support also has a window for exposing the sheet metal bracket. The back of the headrest body passes through the window and is snapped and fixed to the sheet metal bracket, thereby realizing the installation and fixation of the headrest body on the front of the headrest support.

[0006] In the above scheme: the steel wire bracket includes two supporting steel wires, namely a first supporting steel wire and a second supporting steel wire. The two ends of the first supporting steel wire are respectively welded to the two legs of the headrest rod. The middle part of the second supporting steel wire is welded to the backrest frame. The two ends of the second supporting steel wire are respectively welded to the two ends of the first supporting steel wire. The first supporting steel wire and the second supporting steel wire play a supporting and fixing role.

[0007] In the above solution: the back of the headrest support is provided with two U-shaped clips with rearward openings and two U-shaped clips with downward openings, spaced apart on the left and right. The rearward-opening U-shaped clips are clamped onto the first support wire, and the downward-opening U-shaped clips are clamped onto the second support wire. The upper end of the headrest support, near the window, has two lugs spaced apart on the left and right, which are fixed to the sheet metal bracket with screws. The U-shaped clips, together with the first and second support wires, restrict the back-and-forth and left-and-right swaying of the headrest support. The overall structure is simple and easy to install.

[0008] In the above scheme: both ends of the first supporting steel wire are welded with foot plates, and the lower front end of the headrest cover is fixed to the foot plates with screws. The structure is simple and easy to install.

[0009] In the above solution: the back of the headrest body is provided with four downward-facing limiting grooves arranged in a rectangle, and a limiting protrusion is also provided in the middle of the back of the headrest body. The sheet metal bracket is provided with a limiting clip corresponding to each limiting groove, and a limiting hole is also provided on the sheet metal bracket at the position corresponding to the limiting protrusion. When the headrest body is installed on the sheet metal bracket from top to bottom, the limiting groove can be engaged with the corresponding limiting clip to restrict its downward movement. The limiting groove is also provided with a limiting structure for restricting the left and right movement of the limiting clip. At the same time, the limiting protrusion can be engaged with the limiting hole to restrict its upward movement.

[0010] Four limiting slots cooperate with corresponding limiting clips to restrict the headrest body from moving downwards. The special limiting structure on the limiting slots further prevents the limiting clips from swaying left and right. The cooperation between the limiting protrusion and the limiting hole restricts the headrest body from moving upwards. This multi-directional and multi-layer limiting design ensures that the headrest body is fixed in all directions on the sheet metal bracket, effectively preventing the headrest body from swaying up and down or left and right or falling off during vehicle operation due to bumps, vibrations or sudden braking, providing stable and reliable support for the passenger's head.

[0011] In the above solution: a through hole is pre-drilled on the back cover of the headrest, which is aligned with the limiting protrusion. This through hole is ultimately covered by the headrest cover. When the headrest body needs to be disassembled, first open the headrest cover, then use a common tool such as a pry bar through the pre-drilled hole to push the limiting protrusion forward, disengaging it from the limiting hole. Then, move the headrest body upwards to complete the disassembly. The entire process is simple and direct, requiring no disassembly of other unrelated parts, greatly shortening disassembly time and improving efficiency. It is especially suitable for scenarios requiring quick repair or replacement of the headrest body.

[0012] The beneficial effects of this utility model are:

[0013] 1. The connection design between components is simple and efficient. During installation, simply weld the lower end of the headrest rod to the backrest frame, weld the upper end to the sheet metal bracket, and then weld the wire bracket to the corresponding position. Next, cover and fix the headrest back cover, snap and fix the headrest support components, and finally, snap the back of the headrest body through the window to the sheet metal bracket. The entire installation process requires no complicated procedures or excessive tools, greatly simplifying the installation steps, significantly reducing installation time, and greatly improving production efficiency. 2. Utilizing the snap-fit ​​structure between the headrest body and the sheet metal bracket, the headrest body can be easily removed from the sheet metal bracket. The entire disassembly process requires no complicated operations or special tools, greatly shortening disassembly time and improving the efficiency of repairing, replacing, or cleaning the headrest body.

[0024] like Figure 1 As shown in Figure 9, a quick-installation structure for a seat headrest mainly consists of a headrest assembly and a backrest frame 1. The headrest assembly includes a headrest rod 2, a headrest back cover 3, a headrest support 4, and a headrest body 5.

[0025] The lower end of the headrest rod 2 is welded to the backrest frame 1, and the upper end of the headrest rod 2 is welded to a sheet metal bracket 6. A wire bracket 7 is located below the sheet metal bracket 6 and is welded to the backrest frame 1 and / or the headrest rod 2. The headrest back cover 3 covers the rear side of the headrest rod 2, with its upper front end fixedly connected to the sheet metal bracket 6 and its lower front end fixedly connected to the wire bracket 7. The headrest support 4 covers the front of the headrest back cover 3, with its lower end snapped onto the wire bracket 7 and its upper end fixed to the sheet metal bracket 6. The headrest support 4 also has a window 41 for exposing the sheet metal bracket 6. The back of the headrest body 5 passes through the window and is snapped onto the sheet metal bracket 6, thus achieving the installation and fixation of the headrest body 5 on the front of the headrest support 4.

[0026] Ideally, the steel wire support 7 includes two supporting steel wires, namely a first supporting steel wire 71 and a second supporting steel wire 72. The two ends of the first supporting steel wire 71 are respectively welded to the two legs of the headrest rod 2, and the middle part of the second supporting steel wire 72 is welded to the backrest frame 1. The two ends of the second supporting steel wire 72 are respectively welded to the two ends of the first supporting steel wire 71. The first supporting steel wire 71 and the second supporting steel wire 72 serve to support and fix the backrest.

[0027] Ideally, the back of the headrest support 4 is provided with two rearward-facing U-shaped clips 42 and two downward-facing U-shaped clips 42 spaced apart on the left and right. The rearward-facing U-shaped clips 42 are clamped onto the first support wire 71, and the downward-facing U-shaped clips 42 are clamped onto the second support wire 72. The upper end of the headrest support 4, near the window 41, has two lugs 43 spaced apart on the left and right. The lugs 43 are fixed to the sheet metal bracket 6 with screws. The U-shaped clips 42, together with the first and second support wires 71 and 72, restrict the back-and-forth and left-and-right swaying of the headrest support 4. The overall structure is simple and easy to install.

[0028] Ideally, both ends of the first support wire 71 are welded with foot plates 73, and the lower front end of the headrest cover 3 is fixed to the foot plates 73 with screws. The structure is simple and easy to install.

[0029] Ideally, the back of the headrest body 5 is provided with four downward-facing limiting grooves 51 arranged in a rectangular pattern. A limiting protrusion 52 is also provided in the middle of the back of the headrest body 5. The sheet metal bracket 6 is provided with a matching limiting clip 61 corresponding to each limiting groove 51. The sheet metal bracket 6 is also provided with a limiting hole 62 at the position corresponding to the limiting protrusion 52. When the headrest body 5 is installed on the sheet metal bracket 6 from top to bottom, the limiting groove 51 can be engaged with the corresponding limiting clip 61 to restrict its downward movement. The limiting groove 51 is also provided with a limiting structure for restricting the left and right movement of the limiting clip 61. At the same time, the limiting protrusion 52 can be engaged with the limiting hole 62 to restrict its upward movement.

[0030] Four limiting slots 51 cooperate with corresponding limiting clips 61 to restrict the headrest body 5 from moving downward. The special limiting structure on the limiting slots 51 further prevents the limiting clips 61 from swaying left and right. The cooperation between the limiting protrusions 52 and the limiting holes 62 restricts the headrest body 5 from moving upward. This multi-directional and multi-layer limiting design makes the headrest body 5 fixed in all directions on the sheet metal bracket 6, effectively preventing the headrest body 5 from swaying up and down or left and right or falling off during vehicle operation due to bumps, vibrations or sudden braking, and providing stable and reliable support for the passenger's head.

[0031] Ideally, a through hole 31 is pre-drilled on the headrest cover 3, aligned with the limiting protrusion 52. This through hole 31 is ultimately covered by the headrest cover. When it is necessary to disassemble the headrest body 5, first open the headrest cover, then use a common tool such as a pry bar through the pre-drilled through hole 31 to push the limiting protrusion 52 forward to disengage it from the limiting hole 62. Then, move the headrest body 5 upward to complete the disassembly. The entire process is simple and direct, requiring no disassembly of other unrelated parts, greatly shortening the disassembly time and improving disassembly efficiency. It is especially suitable for scenarios requiring quick repair or replacement of the headrest body 5.
