Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a hidden electric lifting headrest structure for automobile seats. Background Art

[0002] With the spread of the concept of intelligent cockpits, more and more automobile enterprises and users have more diverse scene requirements for the seats in the vehicle. For example, the large bed mode, the cinema mode, etc. all need to involve the connection between the front and rear row seats to form a "large flat floor" space in the vehicle. Demands like this often require the removal of the headrests in the front row or the rear row.

[0003] Most traditional automobile seats are manual headrests. The disassembly of manual headrests is difficult to operate, has requirements for the space on the roof and the position of the seat backrest, and some manual headrests require special tools for disassembly, with cumbersome steps, and the removed headrests also take up a lot of space in the vehicle. With the rise of new energy vehicles in recent years, many electric lifting headrests have emerged on the market one after another. However, the lifting is only limited to the adjustment of the headrest, and the headrest itself cannot be disassembled or is difficult to disassemble, unable to meet the requirements of multi-scene adjustment in the intelligent cockpit. Content of the Utility Model

[0004] Aiming at the problems existing in the above-mentioned prior art, the utility model aims to provide a hidden electric lifting headrest structure for automobile seats, which can completely hide the headrest in the seat backrest to meet the requirements of multi-scene adjustment in the intelligent cockpit.

[0005] To achieve the above purpose, the utility model provides a hidden electric lifting headrest structure for automobile seats, including a headrest assembly and a backrest assembly. The headrest assembly includes a headrest main body and a headrest rod which are assembled with each other. The backrest assembly includes a backrest foam and a backrest frame. An elevating mechanism is fixedly arranged on the backrest frame. The elevating mechanism is connected to the headrest rod and can drive it to move up and down. A receiving groove is provided on the upper surface of the backrest foam corresponding to the headrest main body. The elevating mechanism can drive the headrest main body to move into the receiving groove, so as to be hidden inside the backrest foam, and the upper surface of the hidden headrest main body is flush with the upper surface of the backrest foam.

[0006] In the above solution: The lifting mechanism includes a headrest motor, a fixed sheet metal, a lead screw holder, and a lead screw. The fixed sheet metal is welded to the backrest frame. The headrest motor is mounted on the fixed sheet metal by screws. The lead screw extends vertically, with its upper end coaxially connected to the output shaft of the headrest motor and its lower end movably connected to the lead screw holder. The lead screw holder is fixed to the headrest motor. A headrest rod holder is threadedly sleeved on the lead screw. The bottom end of the headrest rod is connected to the headrest rod holder. The headrest motor can drive the lead screw to rotate, thereby driving the headrest rod holder to move up and down along the lead screw, and further driving the headrest body to move up and down. The lifting mechanism can stably and evenly drive the headrest body to retract into the storage groove for hiding. When the headrest body needs to be in the normal working state, the lifting mechanism can drive the headrest body to completely expose above the upper surface of the backrest foam for passengers to rest on.

[0007] In the above solution: A headrest guide sleeve is fixedly provided on the backrest frame corresponding to the headrest rod. The headrest rod movably passes through the headrest guide sleeve from top to bottom. The bottom end of the headrest rod is used to connect to the headrest rod holder. The headrest guide sleeve helps to reduce the play and abnormal noise of the headrest rod during movement.

[0008] In the above solution: An avoidance groove for allowing the headrest guide sleeve to pass through is provided at the lower rear side of the headrest body. To ensure the stability of the headrest body during driving, the designed height of the headrest guide sleeve is relatively high. At the same time, to ensure that the headrest body can be completely hidden in the backrest foam, an avoidance groove for allowing the headrest guide sleeve to pass through is provided on the headrest body.

[0009] In the above solution: The size of the headrest body matches that of the storage groove, and the headrest body can just retract into the storage groove, which helps to ensure the aesthetics and integrity of the backrest assembly.

[0010] The beneficial effects of the present utility model are as follows: 1. The scene function is realized. For example, when the backrest of the first row needs to be connected and transitioned with the seat cushion of the second row, the headrest can be retracted into the backrest according to the need without disassembling the headrest. 2. The seat can quickly switch between the states with and without a headrest. 3. After all the headrests are stored, no additional space in the vehicle is occupied. 4. After the headrests are stored, the comfort of the backrest is not affected. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Such as Figure 1 —6 shows, a hidden electric lifting headrest structure for an automobile seat, mainly composed of a headrest assembly and a backrest assembly. The headrest assembly includes a headrest main body 2 and a headrest rod 3 which are assembled with each other, and the backrest assembly includes a backrest foam 11 and a backrest frame 1. A lifting mechanism 4 is fixedly arranged on the backrest frame 1, and the lifting mechanism 4 is connected with the headrest rod 3 and can drive it to move up and down.

[0018] On the upper surface of the backrest foam 11, a receiving groove is provided corresponding to the headrest main body 2. The lifting mechanism 4 can drive the headrest main body 2 to move into the receiving groove, so as to be hidden inside the backrest foam 11, and the upper surface of the hidden headrest main body 2 is flush with the upper surface of the backrest foam 11.

[0019] Preferably, the lifting mechanism 4 includes a headrest motor 8, a fixed sheet metal 6, a lead screw cage 9 and a lead screw 10. The fixed sheet metal 6 is welded to the backrest frame 1, and the headrest motor 8 is installed on the fixed sheet metal 6 by screws. The lead screw 10 extends up and down, its upper end is coaxially connected with the output shaft of the headrest motor 8, its lower end is movably connected to the lead screw cage 9, and the lead screw cage 9 is fixed to the headrest motor 8. A headrest rod cage 5 is threadedly sleeved on the lead screw 10, and the bottom end of the headrest rod 3 is connected to the headrest rod cage 5. The headrest motor 8 can drive the lead screw 10 to rotate, so as to drive the headrest rod cage 5 to move up and down along the lead screw 10, and further drive the headrest main body 2 to move up and down.

[0020] The lifting mechanism 4 can stably and uniformly drive the headrest main body 2 to retract into the receiving groove for hiding. When the headrest main body 2 needs to be in a normal working state, the lifting mechanism 4 can drive the headrest main body 2 to completely expose above the upper surface of the backrest foam 11 for the passenger to rest on.

[0021] Preferably, a headrest guide sleeve 7 is fixedly arranged on the backrest frame 1 corresponding to the headrest rod 3. The headrest rod 3 movably passes through the headrest guide sleeve 7 from top to bottom. The bottom end of the headrest rod 3 is used to be connected to the headrest rod cage 5. The headrest guide sleeve 7 is beneficial to reducing the looseness and abnormal noise of the headrest rod 3 during movement.

[0022] Preferably, an avoidance groove 12 for allowing the headrest guide sleeve 7 to pass through is opened at the lower end of the rear side of the headrest main body 2. To ensure the stability of the headrest main body 2 during driving, the designed height of the headrest guide sleeve 7 is relatively high. At the same time, to ensure that the headrest main body 2 can be completely hidden into the backrest foam 11, an avoidance groove 12 for allowing the headrest guide sleeve 7 to pass through is opened on the headrest main body 2.

[0023] Preferably, the size of the headrest body 2 matches that of the storage groove, and the headrest body 2 can just be retracted into the storage groove, which is beneficial to ensuring the aesthetics and integrity of the backrest assembly.
