[0032] The present application is further described below in conjunction with the embodiments and the accompanying drawings.
[0033] Embodiment 1
[0034] As shown in Fig. 1, a rear handrail small table plate installation structure includes a handrail assembly 1 and a small table plate 2 arranged at the top of the handrail assembly 1, and a lifting mechanism arranged between the small table plate 2 and the handrail assembly 1, which can move the small table plate 2 upward relative to the handrail assembly 1 when the handrail small table plate is unfolded for use. Figures 1 to 4 Through the design of the lifting mechanism, the unfolded use height of the small table plate 2 is lifted, avoiding interference with the knees of the passenger, and further ensuring the comfort of the passenger.
[0035] Specifically, the lifting mechanism includes a lifting bracket 3, one end of which is rotatably connected to the front of the handrail assembly 1, and the small table plate 2 is rotatably connected to the end of the lifting bracket 3 away from the handrail assembly 1, the lifting bracket 3 can be flipped from a horizontal posture to a vertical posture, and the small table plate 2 can also be rotated 90° forward or backward relative to the lifting bracket 3, in the folded state of the handrail small table plate, the small table plate 2 and the lifting bracket 3 are both stored in the horizontal posture on the handrail assembly 1, and thus designed, after the lifting bracket 3 is flipped upward to lift the small table plate 2 as a whole, the small table plate 2 is rotated 90° forward or backward relative to the lifting bracket 3, which can ensure that the small table plate 2 is in the use state in the horizontal state, meeting the basic requirements of use.
[0036] Further, the lifting bracket 3 is rotatably installed on the handrail assembly 1 through a pin shaft 4, a transition block 5 is rotatably installed at the end of the lifting bracket 3 away from the pin shaft 4, and one end of the small table plate 2 is rotatably installed on the transition block 5, and the small table plate 2 can be flipped 90° forward relative to the transition block 5, the rotation direction of the transition block 5 relative to the lifting bracket 3 is perpendicular to the rotation direction of the lifting bracket 3 relative to the handrail assembly 1 in space, and the rotation direction of the small table plate 2 relative to the transition block 5 is parallel to the rotation direction of the lifting bracket 3 relative to the handrail assembly 1 in space.
[0037] Further, the lifting bracket 3 is rotatably installed on the handrail assembly 1 through a pin shaft 4, a transition block 5 is rotatably installed at the end of the lifting bracket 3 away from the pin shaft 4, and one end of the small table plate 2 is rotatably installed on the transition block 5, and the small table plate 2 can be flipped 90° forward relative to the transition block 5, the rotation direction of the transition block 5 relative to the lifting bracket 3 is perpendicular to the rotation direction of the lifting bracket 3 relative to the handrail assembly 1 in space, and the rotation direction of the small table plate 2 relative to the transition block 5 is parallel to the rotation direction of the lifting bracket 3 relative to the handrail assembly 1 in space.
[0038] Based on the above design, after the lifting support 3 is flipped up to the vertical position, the small table board 2 is flipped forward by 90° relative to the adapter block 5, and finally the adapter block 5 is rotated left or right relative to the lifting support 3, so that the armrest small table board is convenient for the passenger to use.
[0039] As shown in Figures 2 to 4 , the small table board 2 has a mounting groove 2a on the lower side of the front portion in the folded state of the armrest small table board, and the adapter block 5 is hinged in the mounting groove 2a. After the small table board 2 is flipped forward by 90° relative to the adapter block 5, the small table board 2 can be positioned and supported on the adapter block 5. By designing the small table board 2 to be flipped forward by 90° relative to the adapter block 5, when the lifting support 3 is flipped up to the vertical position, the small table board 2 as a whole can be extended forward, so that when the adapter block 5 is rotated relative to the lifting support 3, the small table board 2 has sufficient rotation space and does not interfere with the passenger.
[0040] In this embodiment, the lifting mechanism further includes a driving device for automatically flipping the lifting support 3. As shown in Figure 6 , the driving device includes a first driving motor 6, and an output gear 6a is fixedly installed on the output end of the first driving motor 6. An arc-shaped tooth plate 3c is formed on the lifting support 3, and the arc-shaped tooth plate 3c is in meshing engagement with the output gear 6a. Through the meshing transmission between the output gear 6a and the arc-shaped tooth plate 3c, the flipping of the lifting support 3 is realized by electric control, and in turn the small table board 2 is conveniently unfolded upward.
[0041] Further, as shown in Figure 5 , the lifting support 3 has an n-shaped structure, which includes two rotating portions 3a arranged in parallel and a connecting portion 3b connecting the two rotating portions 3a. The two ends of the pin shaft 4 are hinged to one ends of the two rotating portions 3a away from the connecting portion 3b. The arc-shaped tooth plate 3c is formed on one end of one of the rotating portions 3a close to the pin shaft 4. The adapter block 5 is hinged to the middle position of the connecting portion 3b. By configuring the lifting support 3 into an n-shaped structure, the lifting support 3 can be more stable in rotation, and at the same time, the small table board 2 can be more stably supported.
[0042] As shown in Figure 6 , a mounting plate 7 is fixedly installed inside the armrest assembly 1, and a folding portion 7a is upwardly folded on each of the left and right ends of the mounting plate 7. The pin shaft 4 is fixedly arranged between the two folding portions 7a, and the first driving motor 6 is fixedly installed on one of the folding portions 7a. By arranging the first driving motor 6 and the pin shaft 4 inside the armrest assembly 1, the overall structure of the armrest assembly 1 can be more compact.
[0043] Further, as shown in Figure 7As shown, the upper end of the folding part 7a is provided with a limiting stop pin 10, and the end of the two rotating parts 3a close to the pin shaft 4 extends towards the corresponding folding part 7a with a baffle 3d. When the lifting support 3 is flipped forward, the baffle 3d can finally abut against the limiting stop pin 7. In this way, the forward flipping angle of the lifting support 3 can be limited.
[0044] Further, the pin shaft 4 is sleeved with a torsion spring 11, the middle part of the pin shaft 4 is provided with a limiting protrusion 4a, the folding part 7a is formed with an arc-shaped hole 7c, one end of the torsion spring 11 abuts against the limiting protrusion 4a, and the other end is arranged in the arc-shaped hole 7c. The end of the rotating part 3a close to the pin shaft 4 is provided with a locking hook 3e. When the lifting support 3 is flipped backward, the locking hook 3e can contact the torsion spring 11 and push the torsion spring 11 to move in the arc-shaped hole 7c. Since the other end of the torsion spring 11 abuts against the limiting protrusion 4a, the torsion spring 11 cannot follow the rotation, and thus forms a lock with the locking hook 3e. In this way, the backward flipping angle of the lifting support 3 can be limited.
[0045] In the embodiment, the locking hook 3e and the arc-shaped toothed plate 3c are formed on one baffle 3d, so as to ensure that the overall structure is more compact.
[0046] As shown in the figure, Figure 8 The rear end of the folding part 7a is fixedly connected with an extension plate 7b, and the ends of the two extension plates 7b away from the folding part 7a are connected through a synchronous rod 8. In the embodiment, one end of the synchronous rod 8 protrudes outward beyond the handrail assembly 1 and is power-connected with a second driving motor 9. In this way, the rotation of the handrail assembly 1 can be controlled by electricity, and thus the folding of the handrail is facilitated.
[0047] As shown in the figure, Figure 9 The top of the handrail assembly 1 is formed with a first accommodating groove 1a matched with the cross section of the lifting support 3, and a second accommodating groove 1b matched with the cross section of the adapter block 5. When the lifting support 3 is flipped backward, it can be finally rotated and folded in the first accommodating groove 1a, and the adapter block 5 can follow the rotation and be finally folded into the second accommodating groove 1b. In this way, after the small table plate 2 is folded, the overall structure of the handrail assembly 1 is more compact.
[0048] The top of the handrail assembly 1 is further provided with a receiving groove 1c arranged in the region between the two rotating parts 3a. In this way, the original storage function of the handrail assembly 1 can be ensured.
[0049] As shown in the figure, Figure 1 The front end of the handrail assembly 1 is fixedly provided with a headrest 12. The headrest 12 can support the head of the occupant when the handrail assembly 1 is rotated and folded backward.
[0050] Based on the above structure, the armrest small table plate mounting structure in actual use process, first by the second drive motor 9 drive armrest assembly 1 rotating to Figure 1 the position, then the first drive motor 6 drive lifting bracket 3 forward to Figure 2 the position, then manually operating small table plate 2 relative to the adapter block 5 forward to Figure 3 90 ° to achieve Figure 4 and Figure 10 the effect shown in the figure, finally horizontal rotation small table plate 2, can achieve and
[0051] the effect shown in the figure.
[0052] By the first drive motor 6 and the second drive motor 9 can make small table plate 2 electrically deployed, at the same time, the design of lifting bracket 3 increases the use height of small table plate 2, so that small table plate 2 horizontal rotation, will not form interference with the knee of the passenger, thereby ensuring the comfort of the passenger.
[0053] As shown in Figure 10 , a kind of automobile seat, including backrest 13 and the rear row armrest small table plate mounting structure described in embodiment one, third storage groove 13a is provided on the front side of backrest 13, armrest assembly 1 can be integrated in the form of overturning in third storage groove 13a by the second drive motor 9 control. Such design, can make armrest assembly 1 when not in use, can be stored in third storage groove 13a, so that the overall structure of automobile seat is more compact.
[0054] Finally, it needs to be explained that the above description is merely the preferred embodiment of the present application, the ordinary skill in the art under the inspiration of the present application, without violating the purpose and claims of the present application, can make a variety of similar expressions, such changes all fall within the scope of the present application.
