Detailed Description
The present utility model will be specifically described with reference to the following examples.
Example 1: as shown in fig. 1 to 7, the passenger car two-row seat recline function adjustable extension device comprises an extension plate 1, a left connection mechanism 200 and a right connection mechanism 300, wherein each of the left connection mechanism and the right connection mechanism comprises an extension plate connecting rod 2, a headrest connecting rod 3, a connecting rod connecting screw 4 and an extension plate connecting screw 5. The expansion board connecting rods 2 are connected with the expansion board 1 at positions close to the edges of the expansion board through expansion board connecting screws 4, in this example, the top surfaces of the heads of the expansion board connecting rods 2 are provided with connecting holes 21, and the expansion board connecting screws 4 are in threaded connection with the corresponding connecting holes 21. The upper part of each headrest connecting rod 3 is provided with a threaded connecting hole, and the expansion plate connecting rod 2 is provided with an angle and length adjusting chute. The connecting rod connecting screw 4 passes through the angle and length adjusting chute 201 and the threaded connecting hole 6 to connect the corresponding expansion plate connecting rod 2 and headrest connecting rod 3 together. Alternatively, the angle and length adjustment slide grooves 201 are provided on each headrest link 3, and the extension plate links 2 are provided with screw connection holes 6. The connecting rod connecting screw 4 passes through the angle and length adjusting sliding groove and the threaded connecting hole to connect the corresponding expansion plate connecting rod 2 and the headrest connecting rod 3 together, so that the same function can be realized. Each headrest link 3 is provided with a headrest connection hole 7. In the above-described structure in which the two expansion plate links 2 and the headrest link 3 are connected, the first type has the following advantages over the second type: 1. saving materials; 2. the processing difficulty and the processing time are reduced. The reason is that when the aluminum alloy section is used in mass production, the headrest connecting rod 3 cannot simultaneously give consideration to the two important through holes (the angle and length adjusting sliding groove 201 and the headrest connecting hole 7), so that the two through holes can be respectively placed on different connecting rods.
Working principle: as shown in fig. 6 and 7, fig. 6 is a future reclined state of the seat 500. Fig. 7 is a seat reclined state. When the headrest 400 is used, the headrest 400 is pulled out of the seat, the insert rod 600 of the headrest penetrates through the headrest connecting hole of the expansion device and then is inserted into the seat, and the headrest can be installed on the seat, and at the moment, most of the expansion plate is positioned below the back of the headrest. When the seat needs to be put down, the headrest is pulled out firstly, the expansion device is taken out, the expansion device is turned for 180 degrees, at the moment, most of the expansion plate is positioned above the back of the headrest, namely, the expansion plate is higher than the headrest, and then two inserted rods of the headrest penetrate through headrest connecting holes of the expansion device and are inserted into the seat. After the seat is laid down, the function of expanding the area of the seat after the seat is laid down can be achieved, the levelness and the horizontal height (length) of the expansion plate can be adjusted by loosening the connecting rod connecting screw according to the requirement, so that the expansion plate of the seat after the seat is laid down can reach a more ideal horizontal state or a required angle state, and the seat is more comfortable to use due to the adjustable function. The expansion device can be improved to adapt to different headrest sizes.
Example 2: the characteristic of this example is, each headrest connecting rod 3 outer wall is equipped with fixed screw hole 8, and fixed screw hole 8 and headrest connecting hole 7 intercommunication, fixed screw hole 8 threaded connection have headrest fixing screw 81. When the headrest is used, if the aperture of the headrest connecting hole is larger than that of the inserted link of the headrest, the fixed can be realized by rotating the headrest fixing screw to press the outer wall of the inserted link of the corresponding headrest. The structure can enable the connecting holes to be compatible with the sizes of the inserting rods of different headrests. The procedure is as in example 1.
Example 3: the characteristic of this example is that the expansion board 1 is provided with a left interval adjusting chute 101 and a right interval adjusting chute 102; the expansion board connecting screw 5 of the left connecting mechanism passes through the left interval adjusting chute, and the expansion board connecting screw of the right connecting mechanism passes through the right interval adjusting chute. When the headrest is used, the distance between the left connecting mechanism and the right connecting mechanism can be adjusted by loosening the extension plate connecting screw, so that the left connecting mechanism and the right connecting mechanism are compatible with the distance between the two inserted bars of different headrests. The rest is the same as in example 1 or example 2.
Example 4: the display board is characterized in that guide protrusions 103 are respectively arranged on the bottom surfaces of the display board at positions corresponding to the left interval adjusting sliding groove 101 and the right interval adjusting sliding groove 102, guide grooves 104 matched with the guide protrusions are respectively arranged on the top surfaces of the head parts of the connecting rods of the expansion board, the guide protrusions are arranged in the corresponding guide grooves, and the guide protrusions are matched with the guide grooves in size. The structure can enable the distance between the left connecting mechanism and the right connecting mechanism to be adjusted more stably, and is also beneficial to the fixation of the distance between the left connecting mechanism and the right connecting mechanism and the expansion board. The procedure is as in example 3.
Example 5: the characteristic of this example is that the threaded connection hole is provided on the side face corresponding to each headrest connecting rod. The connecting rod connecting screw is convenient to screw. The remainder may be the same as the above embodiments.
Example 6: the headrest connecting holes are formed in the front faces of the corresponding headrest connecting rods. The remainder may be the same as the above embodiments.
Example 7: the characteristic of this example is that the outer wall of each headrest connection hole 7 is provided with a noise elimination pad 9 for use in connection with a headrest. When in use, the silencing pad is penetrated through the inserted rod of the headrest, so that the silencing pad is arranged between the seat and the headrest connecting rod. The structure can make the headrest, the seat and the expansion device after the expansion device is installed to be muffled, and reduce noise. The remainder may be the same as the above embodiments.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
