Description

Technical Field

[0001] This utility model belongs to the field of seat assembly technology, and specifically relates to an auxiliary device for assembling the backrest of a high-speed rail seat. Background Technology

[0002] High-speed rail is a type of high-speed rail transportation that is fast, smooth, and comfortable. The carriages are equipped with adjustable seats, which typically include folding tables, charging ports, and footrests. High-speed rail is known for its punctuality and efficiency, making it suitable for medium- and long-distance travel. The design and function of high-speed rail seats are aimed at providing passengers with a comfortable and convenient travel experience.

[0003] Currently, some high-speed rail seat assembly operations use hoisting equipment to assist in handling. However, due to the narrow gap between the high-speed rail seat back and the seat cushion, ordinary hoisting tools are difficult to hook stably. In addition, most existing hoisting tools have fixed structures and cannot flexibly adjust the hook angle, which limits their applicability. To solve the above problems, we provide a high-speed rail seat back assembly auxiliary device. Utility Model Content

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] Example 1:

[0021] refer to Figure 1-4 A high-speed rail seat backrest mounting auxiliary device includes a housing 1, and a drive mechanism 2 is provided inside the housing 1.

[0022] The drive mechanism 2 includes a stepper motor 21. The output end of the stepper motor 21 is bolted to a rotating shaft 22 via a coupling. A first gear 23 is fixedly sleeved on the surface of the rotating shaft 22. A second gear 24 is meshed with the surface of the first gear 23 via teeth. A driven shaft 25 is fixedly sleeved inside the second gear 24. A third gear 26 is meshed with the surface of the second gear 24 via teeth. A first hook 3 is fixedly sleeved inside the third gear 26. A fourth gear 27 is meshed with the surface of the first gear 23 via teeth. A second hook 4 is fixedly sleeved inside the fourth gear 27.

[0023] Specifically, the device, through the setting of the drive mechanism 2, can control the opposing or reverse rotation of the first hook 3 and the second hook 4, realize the switching of the vertical or parallel state of the hook's bent end, thereby quickly and stably hooking or releasing the seat back. The gear transmission structure operates smoothly and reliably, ensuring that the hook will not jam or misalign during rotation, effectively avoiding damage to the seat back and cushion. The overall device has a compact structure, is easy to operate, facilitates the switching of hook states, greatly shortens the assembly time, and has good versatility and adaptability.

[0024] refer to Figure 3 The inner side of the housing 1 is bolted to the stepper motor 21. One end of the rotating shaft 22 is rotatably connected to the housing 1 through the first bearing. Both ends of the driven shaft 25 are rotatably connected to the housing 1 through the second bearing. The surfaces of the first hook 3 and the second hook 4 are rotatably connected to the housing 1 through two third bearings. By setting the third bearings, the first hook 3 and the second hook 4 can rotate stably in the housing 1.

[0025] refer to Figure 4 A reinforcing mechanism 5 is provided on one side of the housing 1. The reinforcing mechanism 5 includes a reinforcing rod 51. Both ends of the reinforcing rod 51 are fixedly connected to sliding sleeves 52. The surfaces of the first hook 3 and the second hook 4 are respectively slidably engaged with the two sliding sleeves 52, so that the sliding sleeves 52 slide on the surfaces of the first hook 3 and the second hook 4, and the first hook 3 and the second hook 4 are reinforced by the reinforcing rod 51.

[0026] refer to Figure 3A connecting mechanism 6 is provided on one side of the housing 1. The connecting mechanism 6 includes a lifting lug 61. One side of the lifting lug 61 is fixedly connected to the housing 1. A connecting ring 62 is sleeved inside the lifting lug 61. By setting the connecting ring 62, it can be connected to the lifting equipment.

[0027] refer to Figure 3 A controller 7 is bolted to one side of the housing 1, and handles 8 are bolted to both the front and back of the housing 1. By setting the controller 7, the stepper motor 21 can be effectively controlled.

[0028] refer to Figure 3 The top of the housing 1 is provided with a cover plate 9, and a fixing bolt 10 is fitted inside the cover plate 9. The bottom of the fixing bolt 10 is threaded to the housing 1. By setting the fixing bolt 10, the cover plate 9 can be easily installed and fixed.

[0029] Brief description of usage: The user can connect the hoisting equipment to the connecting ring 62, then insert the first hook 3 and the second hook 4 into the gap between the backrest and the seat cushion. The stepper motor 21 is started via the controller 7. The stepper motor 21 drives the first gear 23 to rotate clockwise via the rotating shaft 22. Simultaneously, the first gear 23 drives the second gear 24, the third gear 26, and the fourth gear 27 to rotate. This causes the first gear 23 to drive the third gear 26 to rotate clockwise via the second gear 24, and simultaneously drives the fourth gear 27 to rotate counterclockwise. 27 drives the first hook 3 and the second hook 4 to rotate in opposite directions. The bent ends of the first hook 3 and the second hook 4 are perpendicular. When the hoisting equipment is started and the device is raised, the device lifts the seat with the backrest assembled through the first hook 3 and the second hook 4. Conversely, the stepper motor 21 drives the first gear 23 to rotate counterclockwise through the rotating shaft 22. The third gear 26 and the fourth gear 27 drive the first hook 3 and the second hook 4 to rotate in opposite directions. The bent ends of the first hook 3 and the second hook 4 are parallel, which makes it easy to pull the device out from the gap between the backrest and the seat cushion.

[0030] 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.
