The backrest connecting seat 41 is fixed with the backrest tube 1; the backrest connecting seat 41 is pivoted with the fixed seat 42, and the backrest tube 1 and the seat tube 2 adjust the angle of the seat relative to the fixed seat 42 through the seat angle adjusting mechanism 4. Specifically, the backrest connecting seat 41 is provided with a positioning portion 411, the fixing seat 42 is provided with a plurality of positioning portions 421, the positioning portion 411 is a disc structure, the disc structure is provided with a positioning hole 411a through which the latch 44 passes, and the positioning portions 421 are engaging holes through which the latch 44 engages. The latch 44 is slidably inserted between the positioning portion 411 and the position-blocking portion 421, the driving member 43 is provided with a driving portion, and the driving member 43 is rotatably disposed in the back-to-back connection seat 41 to drive the latch 44 to be inserted into or separated from the position-blocking portion 421 through the driving portion, so that the back-to-back connection seat 41 is locked or unlocked relative to the fixing seat 42. More specifically, the following:
as shown in fig. 3, 4 and 5, the driving member 43 is a circular ring structure and is rotatably disposed, the rotating central shaft is coaxial with the pivoting central shaft 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 portion is a concave surface 431 provided on a side surface of the driving member 43. The concave surface 431 is provided deeper and deeper in the circumferential direction of the driving member 43. The concave surface 431 can provide a space for accommodating the latch 44, and the latch 44 can gradually cooperate with the concave surface 431 along with the rotation of the driving element 43, so that the latch 44 slides between the outer plane of the driving element 43 and the concave surface 431, and further the latch 44 gradually exits from the shift portion 421, thereby realizing the unlocking of the back-to-back connection seat 41 and the fixed seat 42. The seat angle adjusting mechanism 4 further includes a resilient member 45, and the resilient member 45 provides a resilient force to disengage the latch 44 from the gear portion 421. The elastic element 45 can make the bolt 44 automatically enter the concave surface 431, so as to automatically unlock the backrest connecting seat 41 and the fixing seat 42. The elastic member 45 may be a compression spring and is disposed between the latch 44 and the positioning portion 411.
Referring to fig. 4, 6, 7 and 8, the seat angle adjusting mechanism 4 further includes a pulling member 46 and a restoring member 48, one end of the pulling member 46 is connected to the driving member 43, and the restoring member provides an elastic force for restoring the driving member 43 when the pulling member 46 pulls the driving member 43. The reset member 48 is a compression spring, one end of the compression spring abuts against the driving member 43, and the other end abuts against the inside of the backrest connecting seat 41. The other end of the pulling element 46 is connected to an actuating mechanism 47. The operating mechanism 47 is provided on the backrest tube 1. The operation mechanism 47 can be disposed at a position far away from the backrest connecting seat 41 by the traction member 46, thereby facilitating the operation of the user. The pulling elements 46 according to the invention are steel wires. Specifically, the operating mechanism 47 includes an operating member 471 and a sliding block 472, the operating member 471 is pivoted to the backrest tube 1, and the sliding block 472 is slidably disposed on the backrest tube 1 and connected to the pulling member 46; the operating member 471 is provided with a driving inclined block 471a, the sliding block 472 is provided with a driving inclined slot 472a, and the driving inclined block 471a is in sliding fit with the driving inclined slot 472a, so that the operating member 471 is connected with the sliding block 472. The driving sloped block 471a can drive the sliding block 472 to move so as to pull the driving member 43 through the pulling member 46.
In summary, the operation principle of the seat angle adjusting mechanism 4 of the present invention is described in detail as follows:
when the angle of the backrest needs to be adjusted, the operating piece 471 is operated, the operating piece 471 rotates to drive the driving inclined block 471a to move, the driving inclined block 471a drives the sliding block 472 to slide through the driving inclined groove 472a, and the sliding block 472 pulls the traction piece 46, so that the other end of the traction piece 46 moves, and the driving piece 43 is pulled to rotate. The driving member 43 rotates a certain angle within the limit of the limiting rib 433, and in the process, the latch 44 slides against the outer plane of the driving member 43 under 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 surface 431, the other end of the latch 44 just completely exits the clamping hole. At this time, the backrest connecting seat 41 and the fixing seat 42 are unlocked from each other and can rotate mutually, and at this time, the backrest tube 1 is rotated to enable the backrest tube 1 and the seat tube 2 to rotate relatively to a required angle. After the angle adjustment is completed, releasing the operating part 471, and under the elastic force action of the resetting part, the driving part 43 reversely rotates and resets and pulls the traction part 46 to reset the operating mechanism 47; in this process, the bolt 44 slides from the concave surface 431 to the outer plane of the driving member 43, and at this time, the bolt 44 is inserted into another engaging hole of the fixing seat 42 again, so that the backrest connecting seat 41 and the fixing seat 42 cannot rotate relatively, that is, are in a locked state, and at this time, the backrest tube 1 can be locked at the current angle, thereby realizing the angle adjustment.
Compared with the prior art, in the invention, the positioning part 411 is arranged on the back connecting seat 41, the stop part 421 is arranged on the fixed seat 42, and the plug pin 44 is arranged between the positioning part 411 and the stop part 421, so that the plug pin 44 can be driven by a driving piece 43 to be inserted into or separated from the stop part 421, when the plug pin 44 is inserted into the stop part 421, the plug pin 44 is inserted and simultaneously positioned between the back connecting seat 41 and the fixed seat 42, thereby achieving the purpose of locking the back connecting seat 41 and the fixed seat 42, and conversely releasing the lock; therefore, when the backrest connecting seat 41 and the fixing seat 42 are unlocked, the backrest connecting seat 41 and the fixing seat 42 can rotate together to realize the angle adjustment of the seat, the whole mechanism has a simple structure, the locking or unlocking 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 has a second embodiment, and the seat angle adjusting mechanism 4 of the second embodiment has a structure substantially the same as that of the above-mentioned embodiment, but is different in that the driving member 43 is provided with a limiting rib 433 capable of abutting against the inner side of the backrest connecting seat 41. Specifically, the driving member 43 has a limiting groove 432 formed at an edge thereof, the limiting rib 433 is formed at one side of the limiting groove 432, the inner side of the backrest connecting seat 41 is protrudingly provided with a limiting protrusion 412, and the limiting protrusion 412 is slidably disposed in the limiting groove 432. The limiting rib 433 is provided to prevent the driving member 43 from excessively rotating, and to ensure that the driving member 43 rotates to a correct position.
The above disclosure is only a preferred embodiment of the present invention, and certainly should not be taken as limiting the scope of the present invention, which is therefore intended to cover all equivalent changes and modifications within the scope of the present invention.
