Detailed Description

The electric vehicle seat folding mechanism comprises a bottom box 1, wherein the bottom box 1 can be used as a main beam framework of a folding electric vehicle, a storage battery and other components are installed in the bottom box 1, a driving rotating plate 2 is hinged to the rear end of the bottom box 1, the driving rotating plate 2 is arranged on the bottom box 1 through a first rotating shaft 3, a driving motor 4 is installed on the first rotating shaft 3, and the driving motor 4 can be started to drive the driving rotating plate 2 to rotate by taking the first rotating shaft 3 as a center.

Two first hinged seats 5 are installed on the upper side face of the driving rotating plate 2, a second rotating shaft 6 is arranged between the two first hinged seats 5, the second rotating shaft 6 is connected with the middle of a linkage folding rod 7, one end of the linkage folding rod 7 is hinged with one end of a follow-up folding plate 9 through a third rotating shaft 8, and the other end of the linkage folding rod 7 is hinged with the rear portion of the seat plate 10. The other end of the follow-up folded plate 9 is hinged with the bottom case 1 through a fourth rotating shaft 11, wherein the fourth rotating shaft 11 can be arranged at the lower position of the front side of the first rotating shaft 3. The front part of the seat plate 10 is hinged with one end of a connecting rod 12, and the other end of the connecting rod 12 is hinged with the active rotating plate 2. The active rotating plate 2 is provided with a second hinged seat 13, and the connecting rod 12 is hinged on the second hinged seat 13.

When the driving motor 4 is started, the driving rotating plate 2, the follower folded plate 9 and the seat plate 10 can be driven to rotate to be close to the upper side surface of the bottom case 1, as shown in a storage state shown in fig. 3, and the driving rotating plate 2, the follower folded plate 9 and the seat plate 10 can also be driven to rotate away from the bottom case 1 to be opened, as shown in a use state shown in fig. 1. The driving motor 4 is actuated to rotate the seat plate 10 closer to or farther from the base case 1.

Referring to the schematic diagrams shown in fig. 4 and 5, the actions of the components during the state switching are described, when the folding mechanism is in an open use state, as shown in fig. 4, the bottom case 1, the driving rotating plate 2, the follower flap 9 and the linkage folding rod 7 are hinged to each other to form a rocker mechanism, and since the bottom case 1 is not moved, the driving rotating plate 2 is positioned by the driving motor 4 after rotating to the right position, the follower flap 9 and the linkage folding rod 7 are also not moved relatively. Similarly, the active rotating plate 2, the connecting rod 12, the seat plate 10 and the linkage folding rod 7 are hinged to each other to form a rocker mechanism, and since the linkage folding rod 7 and the active rotating plate 2 are not moved, the seat plate 10 and the connecting rod 12 are also relatively not moved, that is, after the active rotating plate 2 in the above structure is rotated and positioned, the seat plate 10 is rotated and opened and does not rotate any more, no additional locking device is needed, and at this time, the third rotating shaft 8 is located at the rear end position of the second rotating shaft 6.

When the usage state is changed into the storage state, that is, the state shown in fig. 4 is changed into the state shown in fig. 5, the driving rotating plate 2 rotates counterclockwise around the first rotating shaft 3 in the direction shown in fig. 4, the linkage folding rod 7 is driven to rotate clockwise around the second rotating shaft 6 until the driving rotating plate 2 rotates to the upper side of the bottom case 1, the follower folding plate 9 rotates counterclockwise around the fourth rotating shaft 11 in the rotating process, the third rotating shaft 8 moves to the front position of the second rotating shaft 6, the follower folding plate 9 is located on the upper side of the driving rotating plate 2, the connecting rod 12 and the linkage folding rod 7 rotate clockwise to approach the upper side of the follower folding plate 9, the seat plate 10 is located on the upper side of the follower folding plate 9, and finally the storage state shown in fig. 3 is formed. When the storage state is changed into the use state, the seat plate 10 can be opened by rotating the active rotating plate 2 clockwise only, and the use state shown in fig. 1 is formed after the active rotating plate 2 is positioned under the driving of the linkage folding rod 7. So accomodate and the switching between the user state, it is very convenient to operate.

Further, in order to provide more stable support for the user when the above-mentioned device is in the use state, the opened seat plate 10 can prevent the connecting rod 12 or the linkage folding rod 7 from buckling and deforming, the active rotating plate 2 is provided with a second hinge seat 13, the connecting rod 12 is arranged on the active rotating plate 2 through the second hinge seat 13, and the second hinge seat 13 is located at the front end of the first hinge seat 5. As shown in fig. 6, a limiting groove 16 matched with the connecting rod 12 is further formed at the front end of the driving rotating plate 2, a limiting block 14 is arranged in the limiting groove 16, and when the seat plate 10 rotates to be opened, the connecting rod 12 contacts with the limiting block 14. Wherein the setting of the articulated seat 13 of second can strengthen the connecting rod 12 and initiatively change the joint strength between the board 2, and the setting of spacing groove 16 can effectively avoid rocking about connecting rod 12, and stopper 14 then can inject the turned angle of connecting rod 12, prevents excessively opening of seat board 10 to guarantee above-mentioned seat folding mechanism's normal use. The limiting block 14 can also be used as a limiting device of the seat folding mechanism, when the driving motor 4 cannot play a role in positioning the driving rotating plate 2, the limiting block 14 can synchronously position each component in the seat folding mechanism when limiting the connecting rod 12 to rotate.

Further, in order to ensure that the fourth rotating shaft 11 of the above-mentioned device is installed at a position below the front side of the first rotating shaft 3 and ensure that the third rotating shaft 8 is located at the rear end position of the second rotating shaft 6 in the opened state, the third rotating shaft 8 can move to the front side of the second rotating shaft 6 in the stored state, as shown in fig. 4 and 5, the rear end of the follower flap 9 is connected with the fourth rotating shaft 11 through the bending plate 15. In order to inject the turned angle range of initiative commentaries on classics board 2, install limiting plate 17 at the 1 rear end of under casing, limiting plate 17 is located the both sides of buckling plate 15, and when seat board 10 rotated and opened, initiative commentaries on classics board 2 contacted with limiting plate 17, and limiting plate 17's contact can also effectively strengthen the initiative and change board 2 and be in the intensity under the open mode, guarantees seat folding mechanism's normal use.
