Specific embodiment

The utility model is described in further detail with attached drawing with reference to embodiments.

As shown in Fig. 2,4,6, a kind of small table plate driving device for saddle armrest, including datum plate 7 and sliding peace Support plate 8 on datum plate 7, the driving motor 10 that gear 11 is equipped on datum plate 7 and gear 11 is driven to rotate, support Plate 8 is equipped with the rack gear 8a being meshed with gear 11, and driving motor 10 drives gear 11 to rotate, then engages in 11 rack gear 8a of gear Under the action of, driving support plate 8 can be realized and slided on datum plate 7.It in the present embodiment, is the validity for guaranteeing driving, Gear reduction 13 is additionally provided between gear 11 and driving motor 10, i.e., the output power of driving motor 10 is through gear reduction unit Structure 13 is transferred to gear 11.Wherein gear reduction 13 is a very mature well-known technique, and details are not described herein again.

As shown in Fig. 1,2,5 and 7, datum plate 7 is equipped with the straight line guiding groove 7a parallel with 8 glide direction of support plate, directly The end of line guiding groove 7a is round and smooth to be connected with arc guide groove 7b, and drive shaft 9 is rotatably set in support plate 8, driving The end of turning-bar 9a with outward extension on the outer wall of 9 lower part of shaft, turning-bar 9a are equipped with and straight line guiding groove 7a, arc The guiding parts 9b that guide groove 7b is slidably matched, when assembling product, folding table plate B passes through the peace on 9 top of drive shaft Assembling structure 9c is mounted in the driving device of the utility model.

The unfolding mode of folding table plate B is as follows, first manually by the two pieces of desktop being stacked together overturning tilings, to protect Card using face is exposed, and then under the driving of driving motor 10, support plate 8 moves on datum plate 7, in the process, support As support plate 8 is together along straight line guiding groove 7a sliding, i.e. drive small table plate moves drive shaft 9 on plate 8, works as driving When shaft 9 slides into the arc guide groove position 7b, under the cooperation driving of guiding parts 9b and arc guide groove 7b, drive shaft 9 can rotate, i.e. drive small table plate rotates.Based on two groups of movements that drive shaft 9 is mobile and rotates, folding table Plate B is moveable to user-friendly position, i.e. comprehensive on armrest of realization folding table plate B beats automatically It opens.

Again as shown in figure 5, to guarantee to rotate the fluency being oriented to, the guiding parts 9b is to be mounted on the end turning-bar 9a The directive wheel of downside.

It as shown in Figure 1, 2, is the fluency for guaranteeing the sliding of support plate 8, the two sides of support plate 8, which are symmetrically arranged with to tilt down, prolongs The mounting portion 8b stretched, mounting portion 8b are slidably connected by line slide rail 12 and the side of datum plate 7.

As shown in Figure 2,3, after being completed due to Product Assembly, it is empty to middle frame that the middle part of support plate 8, which is overhead, Support plate 8 plays a supportive role, and datum plate 7 is equipped with the support rim 7c extended towards support plate 8 in the side close to support plate 8, It is distributed on support rim 7c and rolls the ball 7d abutted with support plate 8.

As shown in Fig. 2,3,5, datum plate 7 is equipped with raised line 7e, the side wall of raised line 7e and the side wall group of support rim 7c At the straight line guiding groove 7a, and the thickness of support rim 7c is greater than the thickness of raised line 7e, i.e. the side wall of support rim 7c is high In the side wall of raised line 7e, drive shaft 9 is additionally provided with mounting groove 9d in the position of corresponding support rim 7c side wall, sets in mounting groove 9d There is guide wheel 9e, when drive shaft 9 is slided along straight line guiding groove 7a, guide wheel 9e is slid against in support rim 7c side wall It on part higher than raised line 7e side wall, is designed in this way, not only can guarantee the fluency of mechanism mass motion, but also can avoid drive shaft Movement interference occurs when 9 rotation.

Finally, it should be noted that foregoing description is only the preferred embodiment of the utility model, the common skill of this field Art personnel are under the enlightenment of the utility model, under the premise of without prejudice to the utility model aims and claim, can make Multiple similar expressions, such transformation are each fallen within the protection scope of the utility model.
