Problems solved by technology

[0010] 1. The layout of the two sets of mechanisms on the seat requires a large space, which is not conducive to the layout of the whole chair
[0011] 2. Compared with the realization of functions, the structure is more complicated
[0012] 3. The cost of the two institutions will also increase a lot
[0015] 1) There are many motors and their wiring harnesses are complex, resulting in relatively high system costs;
[0016] 2) The function is relatively single, and it can only be used for simple folding seats;
[0017] 3) Lack of intelligent consideration, unable to achieve effective protection of passengers or luggage on the seat cushion

Embodiment 1

[0110] see Figure 2 to Figure 5 , the single-motor-driven unlocking and folding mechanism 400 of this embodiment includes a driving motor 410 , gears 420 , 430 , a sector gear 440 , and an unlocking cam 450 . The gears 420, 430 are both peripheral gears.

[0111] The driving motor 410 is installed on the lower connecting plate 210 through the driving motor bracket 411 and fasteners. A motor gear 412 is disposed on the output shaft of the driving motor 410 .

[0112] The gear 420 and the sector gear 440 are connected in series through a shaft pin 460 , wherein one end of the shaft pin 460 is pivotally arranged on the lower connecting plate 210 , and the gear 430 and the sector gear 440 are keyed to the shaft pin 460 . The gear 420 meshes with the motor gear 412 , the motor gear 412 drives the gear 420 to rotate, and the gear 420 drives the sector gear 440 to rotate synchronously through the shaft pin 460 . The other end of the pin shaft 460 is arranged on a fixed bracket 48...

Embodiment 2

[0120] see Figure 29 The structure of the unlocking and folding mechanism driven by a single motor in this embodiment is basically the same as that of the unlocking and folding mechanism 400 driven by a single motor in Embodiment 1. The difference is that the lower connecting plate 210 is fixed on the seat cushion 200 by fasteners. On the side panel 220. The working principle of the single-motor-driven unlocking and folding mechanism of this embodiment is also the same as that of Embodiment 1.

Embodiment 3

[0122] see Figure 30 to Figure 33 The single-motor-driven unlocking and folding mechanism 400a of this embodiment includes a driving motor 410a, gears 420a, 430a, 440a, an unlocking cam 450a, a torsion spring seat 460a, a return torsion spring 470a, and an idle travel regulator 480a. Gears 420a, 430a, 440a are all peripheral gears.

[0123] The driving motor 410a is installed on the lower connecting plate 210 through the driving motor bracket 411a and fasteners. A motor gear 412a is disposed on the output shaft of the driving motor 410a.

[0124] Gear 420a, gear 440a, idle stroke regulator 480a, and torsion spring seat 460a are connected in series through a shaft pin 490a, wherein one end shaft of shaft pin 490a is arranged on the lower connecting plate 210, and the other end shaft of shaft pin 490a is arranged on the torsion spring seat In 460a, the torsion spring seat 460a is fixed on a fixed bracket 401a, and the fixed bracket 401a is installed on the lower connecting pl...

Abstract

The invention discloses a single-motor-driven unlocking overturning and folding mechanism and application thereof. The single-motor-driven unlocking overturning and folding mechanism comprises a driving motor and an unlocking overturning and folding mechanism body. After the single-motor-driven unlocking overturning and folding mechanism is applied to a power seat, on the one hand, an angle adjusting device is driven to be unlocked; and on the other hand, a seat backrest is driven to be overturned, folded and unfolded. According to the single-motor-driven unlocking overturning and folding mechanism, through one motor and one set of mechanism, folding and unfolding of the backrest of the single-motor-driven unlocking overturning and folding mechanism are achieved, one-button-type adjustment is achieved through an intelligent adjusting control device, the structure is simple, neat and ingenious, the material using amount is reduced, the cost is reduced, and the boundary dimension of the mechanism is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile seats, in particular to an unlocking and folding mechanism driven by a single motor and its application. Background technique [0002] At present, with the development of the automobile industry and the changes in the automobile market, the demand for seven-seater cars is increasing. The seven-seater cars of the seven-seater models of major automobile manufacturers have been pushed to the market one after another. Among the seven-seater models, the user-friendly functional configuration of the middle and rear seats has become a means for OEMs to attract end consumers under the new normal. Such as the electric folding and flatting function of the middle and rear seat cushions. [0003] At present, there are mainly two adjustment methods for the fold-flat function of the middle and rear seats: [0004] 1. Manual adjustment to realize the action of unlocking and laying down. [0005] In the ac...
