Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to a rear seat flipping and holding mechanism. Background Art

[0002] Due to the limitations of the body structure, pickup trucks have no trunk space in the back row. In order to meet the needs of luggage placement or storage space, it is generally required that the rear seat cushions can be flipped up to free up space under the cushions for convenient placement and retrieval of items.

[0003] There are currently two main ways to keep the seat cushion flipped up:

[0004] (1) The headrest is hung on the headrest rod by a webbing and a hook. The structure is simple, but the operation convenience is poor and the appearance is not good.

[0005] (2) The seat angle can be adjusted and locked by adding a recliner. However, this structure is bulky, which is not conducive to the arrangement of the seat appearance parts and is costly.

[0006] The defects of the seats with similar structures at present are as follows:

[0007] (1) There is no internal retaining mechanism, and it is only fixed to the headrest rod by external webbing hooks, which is inconvenient to operate and unsightly;

[0008] (2) The use of an angle adjuster structure is more expensive;

[0009] (3) Complex structure, many parts and high cost.

[0010] The information disclosed in the above background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as admitting or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.

[0014] Furthermore, it also includes an unlocking pull strap, and the other end of the unlocking handle is connected to the unlocking pull strap.

[0015] Furthermore, it also includes a closed bracket, the middle part of the limiting hook can be rotatably connected to the middle part of the closed bracket, and the two ends of the closed bracket are fixed on the inner side of the supporting bracket.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The utility model has an ingenious structure, low implementation cost and is easy to implement; the limit tooth plate and the limit hook are precision stamped parts with high precision, and there is no risk of shaking after locking; when the seat cushion is folded down, the seat cushion is in a locked state, and there is no risk of abnormal noise due to bumps and vibrations; when the seat cushion is flipped up, the seat cushion is in a locked state, and there is no need for fixing with webbing and hooks, which is convenient for taking and putting luggage and articles, and easy to operate.

DETAILED DESCRIPTION

[0021] In order to explain the technical content, purpose and effect of the utility model in detail, the following is an explanation in combination with the implementation mode and the accompanying drawings. In the description of the implementation mode, it should be understood that the terms indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the implementation mode and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0022] like Figure 1-2 As shown, a rear seat flip-up holding mechanism includes a support bracket 1, a limit tooth plate 2, a limit hook 3, a spring 5, a first synchronization shaft 6, a cushion side plate 7; a second synchronization shaft 8 and an unlocking handle 9; the limit tooth plate 2, the limit hook 3 and the spring 5 are arranged on the inner side of the support bracket 1, and the limit tooth plate 2 is provided with a flip-up tooth groove 22 and a reset tooth groove 21, the flip-up tooth groove 22 and the reset tooth groove 21 are adapted to the limit tooth at one end of the limit hook 2, the other end of the limit hook 2 is connected to one end of the spring 5, the other end of the spring 5 is connected to the support bracket 1, the cushion side plate 7 and the unlocking handle 9 is arranged on the outside of the supporting bracket 1, the first synchronous shaft 6 and the second synchronous shaft 7 pass through the inner and outer sides of the supporting bracket 1 respectively and can rotate, the two ends of the first synchronous shaft 6 are respectively connected to the limiting tooth plate 2 and one end of the cushion side plate 7, and the two ends of the second synchronous shaft 8 are respectively connected to the limiting hook 3 and one end of the unlocking handle 9; under the reverse force of the spring 5, the limiting tooth at one end of the limiting hook 3 can be embedded in one of the flip-up tooth groove 22 and the reset tooth groove 21 on the limiting tooth plate 2, and the other end of the unlocking handle 9 can apply a force to the limiting hook 3, so that the limiting tooth 3 is disengaged from the flip-up tooth groove 22 or the reset tooth groove 21.

[0023] The working principle is: the limit tooth plate 2 and the seat cushion side plate 7 realize synchronous rotation through the first synchronous shaft 6; the limit hook 3 and the unlocking handle 9 realize synchronous rotation through the second synchronous shaft 8; when the seat cushion is in the laid-down position, the limit tooth of the limit hook 3 is inserted into the reset tooth groove 21 on the limit tooth plate 2, and through the reverse force of the spring 5, the seat cushion is in a locked state; the limit tooth on the limit hook 3 is separated from the limit tooth plate 2 by pulling the unlocking handle 9; the seat cushion side plate 7 is manually flipped up, and the unlocking handle 9 is released. Under the reverse force of the spring 5, the limit tooth of the limit hook 3 will be inserted into the flipping tooth groove 22 on the limit tooth plate 2 and maintain the locked state, thereby realizing the function of keeping the seat cushion flipped up.

[0024] As a preferred embodiment of the above embodiment, an unlocking strap 10 is further included, and the other end of the unlocking handle 9 is connected to the unlocking strap 10, so that force can be applied to the unlocking handle 9 at a more convenient operating position, making the operation more convenient.

[0025] As a preferred embodiment of the above embodiment, a closing bracket 4 is further included, the middle part of the limit hook 3 is rotatably connected to the middle part of the closing bracket 4, and the two ends of the closing bracket 4 are fixed to the inner side of the supporting bracket 1. The closing bracket 4 limits the range of motion of the limit hook, so that the limit hook is not easily deformed and invalidated, thereby extending its service life.

[0026] The utility model has an ingenious structure, low implementation cost and is easy to implement; the limit tooth plate and the limit hook are precision stamped parts with high precision, and there is no risk of shaking after locking; when the seat cushion is folded down, the seat cushion is in a locked state, and there is no risk of abnormal noise due to bumps and vibrations; when the seat cushion is flipped up, the seat cushion is in a locked state, and there is no need for fixing with webbing and hooks, which is convenient for taking and putting luggage and articles, and easy to operate.

[0027] Although the present invention has been described in detail above with specific implementation methods, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention are within the scope of protection claimed by the present invention.
