Example 1

Referring to fig. 1 and 2, the present utility model provides a folding handrail mechanism 1. The folding handrail mechanism 1 includes a mounting plate 01, a front swing arm 02, a rear swing arm 03, a cross tube 04, and an index pin 05. The front swing arm 02 and the rear swing arm 03 are respectively arranged at two ends of the mounting plate 01, and the front swing arm 02 is hinged with the mounting plate 01. The rear swing arm 03 is hinged with the mounting plate 01. One end of the transverse tube 04 is hinged with one end of the front swing arm 02, which is far away from the mounting plate 01, and the other end of the transverse tube is hinged with one end of the rear swing arm 03, which is far away from the mounting plate 01. The index pin 05 passes through the front swing arm 02 and is arranged in an index hole on the mounting plate 01.

The following describes the structure of each sub-component in detail:

the mounting plate 01 is used to fix the folding handrail mechanism 1 to the vehicle body. The mounting plate 01 is various in form and structure, and is desirable in both structure and form as long as it can realize functional connection with the front swing arm 02 and the rear swing arm 03. In this embodiment, opposite sides of the mounting plate 01 are bent to form a first side wall 11 and a second side wall 12. The first sidewall 11 is provided with a first front connection hole 111. The second side wall 12 is provided with a second front connecting hole 121. The front swing arm 02 is provided with a first front swing hole 21 at one end close to the mounting plate 01. The first connecting pin 13 passes through the first front connecting hole 111, the first front swinging hole 21 and the second front connecting hole 121 once to connect the front swinging arm 02 with the mounting plate 01.

In this embodiment, the connection between the rear swing arm 03 and the mounting plate 01 is similar to the connection between the front swing arm 02 and the mounting plate 01. The end of the first side wall 11 far away from the front swing arm 02 is provided with a first rear connecting hole 112. The end of the second side wall 12 far away from the front swing arm 02 is provided with a second rear connecting hole 122. A first rear swing hole 32 is formed in one end, close to the mounting plate 01, of the rear swing arm 03. The second connecting pin 14 sequentially passes through the first rear connecting hole 112, the first rear swinging hole 32 and the second rear connecting hole 122 to realize connection between the rear swinging arm 03 and the mounting plate 01.

The swing motion rhythms of the front swing arm 02 and the rear swing arm 03 are synchronous, and the folding handrail mechanism 1 mainly takes into consideration two states, namely an unfolding state and a folding state. In order to ensure that the folding handrail mechanism 1 can be kept stable in these two states, the index pins 05 are provided to perform positional positioning in both states.

Specifically, an index plate is formed on the first sidewall 11 at an end near the front swing arm 02. The dividing plate is provided with dividing holes at intervals. The front swing arm 02 is provided with a fixing hole 22. The index pin 05 is provided on the front swing arm 02, and one end thereof passes through the fixing hole 22 and is then provided in the index hole.

The indexing pin 05 is a detent mechanism with a knob which can be rotated to control the entry or exit of the detent end of the indexing pin 05 into or from the indexing aperture. The position of the indexing holes is determined by the two state positions of the folding handrail mechanism 1. In order to ensure that the indexing holes can adapt to the positions of the indexing pins 05, in this embodiment, the indexing plate is in a sector shape, and the indexing holes are arranged at intervals around the axis of the indexing plate. Meanwhile, the indexing holes are waist-shaped holes, and the long edges of the indexing holes are arranged along the radial direction of the indexing plate.

In addition, in the present embodiment, the damper 06 is provided in consideration of a certain degree of automaticity and controllability of the folding handrail mechanism 1 in the unfolding and folding process. One end of the damper 06 is hinged on the first connecting pin 13, and the other end is hinged with the rear swing arm 03. Specifically, the rear swing arm 03 is provided with a damping hole 33. The third connecting pin 31 is disposed in the damping hole 33. One end of the damper 06 is hinged to the third connecting pin 31.

Since the two ends of the third connecting pin 31 protrude, they interfere with the first side wall 11 and the second side wall 12 of the mounting plate 01 when folding, and thus, the first side wall 11 and the second side wall 12 are provided with notches for placing the two ends of the third connecting pin 31.

It will be appreciated that an anti-slip cover 07 is also provided in order to increase comfort of use and ease of deployment and collapse. The antiskid sleeve 07 is sleeved on the transverse tube 04. In order to strengthen the structure, weight reducing holes are formed in the front swing arm 02 and the rear swing arm 03 to reduce the weight of the folding handrail mechanism 1. In addition, the folding handrail mechanisms 1 are arranged at two sides of the seat position, and the folding handrail mechanisms 1 at two sides are arranged in a mirror image mode.

In summary, the main effective effects of the embodiments provided by the present utility model are as follows:

the front swing arm 02, the rear swing arm 03, the mounting plate 01 and the transverse tube 04 form a swing rod mechanism, so that the armrests can be unfolded and folded, the positions of seats can be independently separated during unfolding, passengers can conveniently support the seats, and the positions of the seats in parallel can be spatially connected during folding to form a wide space for the passengers to rest.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The foregoing examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
