Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, specifically to a novel flip-top structure for automotive seat hand warmers. Background Technology

[0002] In the commercial vehicle sector, due to their positioning as luxury cars, their seats are often equipped with displays that allow users to view video information during the journey. Initially, these car seats typically achieved this function by directly mounting fixed upright displays or by using motors to lift and lower displays built into the seat armrests. However, these installation methods meant that the touchscreen still occupied space when not in use. Therefore, products on the market now feature flip-up designs that allow the touchscreen to be stored away when not in use, thus improving overall space utilization.

[0003] For example, our company previously filed a Chinese patent application with publication number CN220947689U, which disclosed a flip-top structure for a seat armrest with a control system. The structure is characterized by including an inner armrest housing, an openable cover plate on the inner armrest housing, a frame connected to the cover plate, a touch screen on the side of the cover plate facing the frame, a rotating end on one side of the frame serving as a rotating end rotatably connected to the inner armrest housing, an installation space within the inner armrest housing, a motor within the installation space, and a transmission mechanism connecting the motor to the frame. The motor drives the cover plate to flip through the transmission mechanism, thereby opening or closing the cover plate.

[0004] In the above technical solution, the drive sleeve moves along the threaded rod to drive the drive rod to extend and retract. During the extension and retraction of the drive rod, the drive rack on the drive rod and the external teeth on the rotating end of the frame mesh with the drive rack to drive the frame to rotate, thereby enabling the cover plate connected to the frame to flip. However, during long-term use, it was found that the flipping of the cover plate is mainly powered by the meshing drive rack and external teeth. However, long-term meshing will cause the drive rack and external teeth to wear and become unable to mesh properly, making it impossible to drive the cover plate to flip properly, which is not conducive to long-term use. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new flip-top structure for car seat hand warmers, which is conducive to long-term use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel flip-top structure for automotive seat armrests, comprising an inner armrest housing, an openable cover plate on the inner armrest housing, the cover plate being located on the side facing the inner armrest housing for connecting a touch screen, the cover plate being connected to a frame, one end of the frame serving as a rotating end, the rotating end being rotatably connected to the inner armrest housing, an installation space being provided below the inner armrest housing, a motor being provided within the installation space, a transmission arm being connected to the rotating end, a movable drive sleeve being provided between the motor and the transmission arm, and a drive arm being connected between the drive sleeve and the transmission arm, the motor being used to drive the drive sleeve to move, thereby driving the transmission arm to rotate, thus opening or closing the cover plate.

[0007] The present invention is further configured such that: the transmission arm is provided with a protruding ring, and the rotating end is provided with a groove opposite to the protruding ring, the protruding ring is embedded in the groove, and the two are fixedly connected.

[0008] The present invention is further configured such that: the bottom of the inner shell of the armrest is provided with a downwardly extending connecting flange, the connecting flange is provided with a through first connecting hole, the transmission arm and the rotating end are provided with a through second connecting hole, and the first connecting hole and the second connecting hole are rotatably connected by a pin.

[0009] The present invention is further configured as follows: a box is provided in the installation space, an installation cavity is provided in the box, a threaded rod is rotatably connected in the installation cavity, a drive sleeve is fitted on the outer periphery of the threaded rod and forms a threaded engagement between them, a guide port communicating with the installation cavity is provided on the side wall of the box, a detachable connecting rod is provided on the drive sleeve, one end of the connecting rod extends to the outside of the installation cavity through the guide port, one end of the drive arm is fitted on the outer periphery of the connecting rod to form a rotatable connection between the two, and the other end is rotatably connected to the transmission arm.

[0010] The present invention is further configured such that: the output end of the motor extends into the mounting cavity as an extension end, and a driving bevel gear is fitted and fixed on the extension end; a driven bevel gear is fitted and fixed on one side end of the threaded rod; and the driven bevel gear meshes with the driving bevel gear.

[0011] The present invention is further configured such that: a detachable nut is provided on one side of the connecting rod, and a threaded groove is provided on the connecting rod; the end of the detachable nut can form a threaded engagement with the threaded groove; the detachable nut is used to prevent the drive arm from falling off the connecting rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Because of the inclusion of a drive sleeve, a transmission arm, and a drive arm, when the motor drives the drive sleeve to move, the drive arm can rotate along with the drive sleeve, causing the frame connected to the transmission arm to rotate as well, thus opening or closing the cover. By adopting the above structure, only the movement of the drive sleeve and the corresponding rotation of the transmission arm and drive arm are needed to drive the cover to flip. This avoids the problem of excessive wear on the transmission structure caused by the use of drive racks and external teeth for power transmission in existing technologies, thereby extending the service life of the transmission structure and ensuring the stability of the cover's flipping during long-term use, which is beneficial for long-term use.

[0022] like Figures 1 to 6 As shown, this utility model discloses a novel flip-top structure for a car seat armrest, including an armrest embedded shell 1. An openable cover 2 is provided on the armrest embedded shell 1, with the cover 2 located on the side facing the armrest embedded shell 1 for connecting a touch screen. A frame 3 is connected to the cover 2 and is connected to the armrest embedded shell 1 via the frame 3. One end of the frame 3 serves as a rotating end 31, rotatably connected to the armrest embedded shell 1. An installation space 4 is provided below the armrest embedded shell 1, containing a motor 15. A transmission arm 5 is connected to the rotating end 31. A movable drive sleeve 6 is provided between the motor 15 and the transmission arm 5. A drive arm 7 is connected between the drive sleeve 6 and the transmission arm 5. Thus, the drive sleeve 6, transmission arm 5, and... The drive arms 7 can form a reverse crank-slider structure. When the drive sleeve 6 is moved by the motor 15, the drive arm 7 can drive the transmission arm 5 to rotate, so that the frame 3 connected to the transmission arm 5 rotates with the transmission arm 5, thereby opening or closing the cover plate 2. By adopting the above structure, only the movement of the drive sleeve 6 and the corresponding rotation of the transmission arm 5 and drive arm 7 are needed to drive the cover plate 2 to flip. This avoids the problem of large wear on the transmission structure caused by the use of drive racks and external teeth for power transmission in the prior art, thereby extending the service life of the transmission structure and ensuring the stability of the cover plate 2 during long-term use, which is beneficial for long-term use.

[0023] In this embodiment, a protruding ring 51 is provided on the transmission arm 5, and a groove 311 opposite to the protruding ring 51 is provided on the rotating end 31. When the rotating end 31 is connected to the transmission arm 5, the protruding ring 51 is embedded in the groove 311. The extrusion deformation generated by the protruding ring 51 can stably embed the protruding ring 51 in the groove 311, thereby enabling a stable fixed connection between the rotating end 31 and the transmission arm 5, thus ensuring that the frame 3 and the transmission arm 5 move synchronously.

[0024] In this embodiment, a downwardly extending connecting flange 8 is provided at the bottom of the inner shell 1 of the armrest. A first connecting hole is provided on the connecting flange 8, and a second connecting hole 52 is provided on the transmission arm 5 and the rotating end 31. After the transmission arm 5 and the rotating end 31 are fixed, a rotating pair connection can be formed by inserting a pin into the first connecting hole and the second connecting hole 52. In this way, when the drive sleeve 6 is moved, the drive arm 7 can push the transmission arm 5 to rotate around the central axis of the first connecting hole and the second connecting hole 52, thereby realizing the opening or closing of the cover plate 2.

[0025] In this embodiment, the structure that drives the drive sleeve 6 to move is as follows: a box 9 is provided in the installation space 4, and an installation cavity 91 is provided in the box 9. A threaded rod 10 is rotatably connected to the installation cavity 91 through a bearing. The drive sleeve 6, which can form a threaded engagement with the threaded rod 10, is fitted on the threaded rod 10. Thus, after the threaded rod 10 is rotated, the drive sleeve 6 can move along the axial direction of the threaded rod 10 as the threaded rod 10 rotates. The side wall of the box 9 is provided with a guide port 92 that communicates with the installation cavity 91. The drive sleeve 6 is provided with a detachable connecting rod 11 that is threadedly connected. One end of the connecting rod 11 extends to the outside of the installation cavity 91 through the guide port 92. One end of the drive arm 7 is fitted around the outer periphery of the connecting rod 11 to form a rotatable connection between the two. The other end is rotatably connected to the transmission arm 5 through a pin. It should be noted that the outer wall of the drive sleeve 6 must abut against the inner wall of the box 9 to prevent the drive sleeve 6 from rotating as the threaded rod 10 rotates.

[0026] In addition, an anti-loosening nut 14 is provided on one side of the connecting rod 11. The connecting rod 11 is provided with a threaded groove. The end of the anti-loosening nut 14 can form a threaded engagement with the threaded groove. In this way, after one end of the drive arm 7 is fitted onto the outer periphery of the connecting rod 11, the drive arm 7 can be axially limited by screwing the anti-loosening nut 14 into the threaded groove to prevent the drive arm 7 from falling off the connecting rod 11.

[0027] In addition, the output end of the motor 15 extends into the mounting cavity 91 as an extension end, and a driving bevel gear 12 is fixedly fitted on the extension end. A driven bevel gear 13 is fixedly fitted on one side end of the threaded rod 10. The driven bevel gear 13 meshes with the driving bevel gear 12. In this way, the power of the motor 15 can be transmitted to the threaded rod 10 through the meshing driving bevel gear 12 and driven bevel gear 13, so as to drive the threaded rod 10 to rotate.

[0028] In this embodiment, the motor 15 is specifically a servo motor. The installation space 4 can be used to install a circuit board. The corresponding number of pulses is pre-programmed according to the flip angle of the cover plate 2. When the motor 15 outputs the corresponding number of pulses, it stops. Control buttons that are electrically connected to the circuit board are installed on the cover plate 2. By pressing different control buttons, the forward and reverse rotation of the motor 15 can be controlled, thereby controlling the opening or closing of the cover plate 2.

[0029] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
