More specifically, the following is:
as shown in fig. 3, 4 and 5, the driving member 43 is in a ring structure and is rotatably disposed, a rotation center axis is coaxial with a pivot center axis of the backrest connecting seat 41 pivoted to the fixing seat 42, and the driving member 43 is disposed in the backrest connecting seat 41, so that the structure of the whole seat angle adjusting mechanism 4 is more reasonable and compact. The driving part is a concave surface 431 provided on a side surface of the driving tool 43. The concave surface 431 is disposed deeper and deeper in the circumferential direction of the driving member 43. The concave surface 431 may provide a space for accommodating the latch pin 44, and the latch pin 44 may gradually cooperate with the concave surface 431 along with the rotation of the driving member 43, so that the latch pin 44 slides between the outer plane of the driving member 43 and the concave surface 431, and the latch pin 44 gradually exits the gear portion 421, thereby releasing the lock between the backrest connecting seat 41 and the fixed seat 42.

The driving member 43 rotates within the range of the limiting rib 433 by a certain angle, and in this process, the latch 44 slides against the outer plane of the driving member 43 under the action of the elastic force of the elastic element 45, and slides from the outer plane of the driving member 43 into the concave surface 431. When the latch 44 completely enters the lowest position of the concave 431, the other end of the latch 44 just completely exits the engagement hole. At this time, the backrest connecting seat 41 and the fixing seat 42 are mutually unlocked, and can rotate with each other, and at this time, the backrest tube 1 is rotated again, so that the backrest tube 1 and the seat tube 2 are relatively rotated to a desired angle. When the adjustment of the angle is completed, the operating member 471 is released, and the driving member 43 reversely rotates to reset and pulls the traction member 46 to reset the operating mechanism 47 under the action of the elastic force of the reset member; in this process, the latch 44 slides from the concave 431 to the outer plane of the driving member 43, and at this time, the latch 44 is inserted into the other engagement hole of the fixing base 42 again, so that the back support connecting seat 41 and the fixing base 42 cannot rotate relatively, i.e. are in a locked state, and at this time, the back support tube 1 can be locked at the current angle, thereby realizing the adjustment of the angle.
Compared with the prior art, the positioning part 411 is arranged on the backrest connecting seat 41, the gear position part 421 is arranged on the fixed seat 42, and the bolt 44 is arranged between the positioning part 411 and the gear position part 421, so that the bolt 44 can be driven to be inserted into or separated from the gear position part 421 through the driving piece 43, when the bolt 44 is inserted into the gear position part 421, the bolt 44 is inserted between the backrest connecting seat 41 and the fixed seat 42, thereby achieving the purpose of locking the backrest connecting seat 41 and the fixed seat 42, and conversely releasing the lock; therefore, when the backrest connecting seat 41 and the fixed seat 42 are unlocked, the backrest connecting seat 41 and the fixed seat 42 can be rotated together, so that the angle adjustment of the seat is realized, the whole mechanism has a simple structure, the locking or the locking can be realized only by operating the driving piece 43, and the operation is very convenient.
In addition, as shown in fig. 4, the seat angle adjusting mechanism 4 of the present invention further includes a second embodiment, and the seat angle adjusting mechanism 4 of the second embodiment has substantially the same structure as that of the above embodiment, except that the driving member 43 is provided with a limiting rib 433 capable of abutting against the inner side of the backrest connecting base 41. Specifically, the edge of the driving member 43 is provided with a limiting groove 432, one side of the limiting groove 432 is provided with a limiting rib 433, the inner side of the backrest connecting seat 41 is provided with a limiting protrusion 412 in a protruding manner, and the limiting protrusion 412 is slidably disposed in the limiting groove 432. The positioning rib 433 prevents the driving member 43 from being excessively rotated, and ensures that the driving member 43 is rotated to an accurate position.
The foregoing disclosure is merely illustrative of the principles of the present invention, and thus, it is intended that the scope of the invention be limited thereto and not by this disclosure, but by the claims appended hereto.
