[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0026] This application provides a car seat unlocking device, as shown in the schematic diagram below. Figure 1-3 As shown. The car seat unlocking device includes a seat cushion frame 1 and a backrest frame 2 connected to the seat cushion frame 1. The seat cushion frame 1 and the backrest frame 2 are connected by a backrest unlocking mechanism 3.
[0027] The backrest unlocking mechanism 3 includes a rotating shaft 31 passing through the bottom of the backrest frame 2 and bearing components 32 connected to both ends of the rotating shaft 31. The bearing components 32 are connected to the seat cushion frame 1.
[0028] It should be noted that, in this embodiment, the car seat unlocking device includes a seat cushion frame 1 and a backrest frame 2, which are connected by a backrest unlocking mechanism 3. A rotating shaft 31 in the backrest unlocking mechanism 3 passes through the bottom end of the backrest frame 2, and bearing components 32 are connected to both ends of the rotating shaft 31, which are in turn connected to the seat cushion frame 1. When the backrest angle needs to be adjusted, the backrest frame 2 rotates around the rotating shaft 31, and the bearing components 32 provide support for the rotating shaft 31, thereby enabling the backrest frame 2 to rotate relative to the seat cushion frame 1.
[0029] Optionally, such as Figure 1 and Figure 2 As shown, the top two sides of the seat cushion frame 1 are provided with wing plates 11, and the ends of the wing plates 11 away from the seat cushion frame 1 are provided with integrally formed termination plates 12. The wing plates 11 are connected to the adjacent bearing components 32.
[0030] In this embodiment, wing plates 11 are provided on both sides of the top of the seat cushion frame 1. Termination plates 12 are integrally formed on both sides of the wing plate 11 away from the seat cushion frame 1. The wing plates 11 are connected to adjacent bearing components 32. During backrest rotation, the wing plates 11 are responsible for transmitting the force of the seat cushion frame 1 to the bearing components 32 and stabilizing the position of the bearing components 32. The termination plates 12 limit the rotation range of the backrest. The wing plates 11 enhance the stability of the connection between the seat cushion frame 1 and the bearing components 32, ensuring smooth force transmission during backrest rotation. The termination plates 12 effectively limit the rotation range of the backrest, preventing excessive backrest rotation and safety issues, greatly improving the safety of the seat during use.
[0031] Optionally, such as Figure 2 and Figure 3 As shown, a movable plate 13 is provided between the two end plates 12, and the movable plate 13 is connected to the outer surface of the backrest frame 2.
[0032] In this embodiment, a movable plate 13 is provided between the two end plates 12, and the movable plate 13 is connected to the outer surface of the backrest frame 2. When the backrest frame 2 rotates, the movable plate 13 moves with the backrest frame 2 and moves between the two end plates 12, and its range of movement is limited by the end plates 12.
[0033] Optionally, such as Figure 2 and Figure 3 As shown, the bearing component 32 includes an outer shell 321 connected to the surface of the wing plate 11 near the backrest frame 2, and an inner shell 322 rotatably connected to the outer shell 321. The inner shell 322 is connected to the bottom end of the backrest frame 2.
[0034] In this embodiment, the bearing component 32 consists of an outer shell 321 connected to the surface of the wing plate 11 near the backrest frame 2, and an inner shell 322 rotatably connected to the outer shell 321. The inner shell 322 is connected to the bottom end of the backrest frame 2. When the backrest frame 2 rotates, the inner shell 322 rotates together with the backrest frame 2 around the rotation connection point with the outer shell 321, while the outer shell 321 is fixed on the wing plate 11, providing stable support for the rotation of the inner shell 322.
[0035] Optionally, such as Figure 2 and Figure 3 As shown, a bearing 323 is connected inside the outer shell 321, and the outer shell 321 is rotatably connected to the inner shell 322 through the bearing 323.
[0036] In this embodiment, a bearing 323 is connected inside the outer shell 321, and the outer shell 321 is rotatably connected to the inner shell 322 through the bearing 323. When the inner shell 322 rotates under the drive of the backrest frame 2, the rolling of the bearing 323 greatly reduces the friction between the inner shell 322 and the outer shell 321, allowing the inner shell 322 to rotate more smoothly around the outer shell 321.
[0037] Optionally, such as Figure 2 and Figure 3 As shown, an electromagnet 324 is connected inside the outer shell 321, and the electromagnet 324 is sleeved on the outside of the inner shell 322.
[0038] In this embodiment, an electromagnet 324 is connected inside the outer shell 321, and the electromagnet 324 is fitted onto the outside of the inner shell 322. When the user needs to unlock the backrest, the electromagnet 324 is energized by a control button inside the vehicle. The energized electromagnet 324 generates a magnetic field, which acts on the inner shell 322, reducing the friction between the inner shell 322 and the outer shell 321, thus facilitating the rotation of the backrest. Once the backrest has rotated to the desired position, the user operates the button again to de-energize the electromagnet 324, restoring the friction between the inner shell 322 and the outer shell 321, thereby locking the backrest in place.
[0039] Optionally, such as Figure 2 and Figure 3 As shown, the outside of the rotating shaft 31 is provided with a plurality of integrally formed connecting keys 311. The plurality of connecting keys 311 are arranged around the central axis of the rotating shaft 31. The connecting keys 311 are inserted into the connecting groove 325, which is located inside the housing of the inner shell 322.
[0040] In this embodiment, a plurality of integrally formed connecting keys 311 are provided on the outside of the rotating shaft 31, and these connecting keys 311 are arranged around the central axis of the rotating shaft 31. A connecting groove 325 is provided inside the inner shell 322 to engage with the connecting keys 311. When the backrest frame 2 drives the rotating shaft 31 to rotate, the connecting keys 311 slide within the connecting groove 325, thereby ensuring that the rotating shaft 31 and the inner shell 322 can rotate synchronously.
[0041] The specific operation method of this utility model is as follows:
[0042] When the backrest needs to be unlocked, the user activates the electromagnet 324 via the control button inside the vehicle. After the electromagnet 324 is energized, it generates a magnetic field that attracts the inner shell 322, reducing the friction between it and the outer shell 321. At this time, the user can easily rotate the backrest frame 2.
[0043] During the rotation of the backrest frame 2, the rotating shaft 31 is driven to rotate together. The connecting key 311 on the rotating shaft 31 slides in the connecting groove 325 of the inner shell 322, ensuring the stability of the rotation.
[0044] Once the backrest has rotated to the desired position, the user operates the control button again to de-energize the electromagnet 324, restoring the friction between the inner shell 322 and the outer shell 321, and locking the backrest frame 2 in the current position.
[0045] During the rotation of the backrest, the movable plate 13 moves between the two stop plates 12, which limits the range of rotation of the backrest and prevents excessive rotation of the backrest from causing safety hazards.
[0046] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
