[0029] In order to make the technical solutions and advantages in the embodiments of the present application clearer and more understandable, the following further details the exemplary embodiments of the present application with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than an exhaustive list of all embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0030] Embodiment 1

[0031] This embodiment provides a displacement adjusting mechanism, including a support member 1, a first connecting member 2 rotatably connected to the support member 1, and a second connecting member 3 slidably connected to the first connecting member 2;

[0032] As Figures 1-6 shown, one end of the second connecting member 3 is the first adjusting end 31, the other end of the second connecting member 3 is the second adjusting end 32, a guiding groove 33 is provided between the first adjusting end 31 and the second adjusting end 32, the lower part of the first connecting member 2 rotates relative to the support member 1, the upper part of the first connecting member 2 slides along the guiding groove 33 and supports the second connecting member 3, and the angle of the second connecting member 3 in the horizontal direction can be adjusted.

[0033] This embodiment provides a displacement adjusting mechanism, further including a limiting component 4 provided on the first connecting member 2 and movably clamped with the support member 1. The limiting component 4 can be a mechanical lock structure or an electronic lock structure. When it is necessary to lock the limiting component 4 with the support member 1, the limiting component 4 is positioned close to the support member 1; when it is necessary to unlock the limiting component 4 from the support member 1, the positioning of the limiting component 4 with the support member 1 is cancelled.

[0034] When the second connecting member 3 is at a high position and the angle of the second connecting member 3 in the horizontal direction is relatively large, when the upper part of the first connecting member 2 rotates relative to the support member 1 to the high position, the limiting component 4 is clamped and positioned with the support member 1 and at the same time plays a role in supporting and positioning the first connecting member 2. The first connecting member 2 slides to a position close to the second adjusting end 32 of the guiding groove 33, and the second connecting member 3 is kept stable through the positioning function of the limiting component 4. When the second connecting member 3 is at a low position and the angle of the second connecting member 3 in the horizontal direction is relatively small, the limiting component 4 is disengaged from the limiting of the support member 1. The upper part of the first connecting member 2 rotates relative to the support member 1 to the low position, the second connecting member 3 tends to be horizontal, and the first connecting member 2 slides to a position close to the first adjusting end 31 of the guiding groove 33.

[0035] The limiting component 4 includes a locking tongue 41 rotatably connected to the first connecting member 2. A locking hook 11 is arranged on the support member 1, and the locking tongue 41 is in clamping cooperation with the locking hook 11. The limiting component 4 further includes a shaft member 42 arranged on the first connecting member 2. The locking tongue 41 is installed on the shaft member 42, and an elastic member (not shown in the figure) sleeved on the shaft member 42 is arranged between the locking tongue 41 and the first connecting member 2. After the locking tongue 41 rotates relative to the first connecting member 2, it can be automatically reset through the elastic member. In this embodiment, the elastic member can be a spring.

[0036] The limiting component 4 further includes a pull rod 43 rotatably connected to the locking tongue 41, and the opening of the locking tongue 41 is rotatably clamped with or separated from the locking hook 11. When the pull rod 43 is stressed to drive the locking tongue 41 to rotate around the shaft member 42, the locking tongue 41 is separated from the locking hook 11; specifically, when the pull rod 43 is pulled down and acts on the locking tongue 41, the elastic member is compressed, the opening of the locking tongue 41 rotates upwards, and the opening of the locking tongue 41 disengages from the locking hook 11; when the pull rod 43 is released from the force, the locking tongue 41 is subjected to the rebounding action of the elastic member, and the locking tongue 41 resets and its opening rotates downwards, and can be locked with the locking hook 11 again or can be in a vacant state. The end of the locking tongue 41 close to the opening is an arc-shaped structure 44. When the locking tongue 41 resets to the locking hook 11, during the process of the locking tongue 41 locking the locking hook 11 again, with the buffering effect of the elastic member, the arc-shaped structure 44 can smoothly transition into the opening by abutting against the locking hook 11, so that the opening of the locking tongue 41 is clamped with the locking hook 11, avoiding the problem that the locking tongue 41 is stuck during reset.

[0037] In this embodiment, the first connecting member 2 is rotatably connected to the support member 1, the second connecting member 3 is slidably connected to the first connecting member 2, the lower part of the first connecting member 2 rotates relative to the support member 1, and the upper part of the first connecting member 2 slidably supports the second connecting member 3, so as to realize that the angle of the second connecting member 3 in the horizontal direction can be adjusted, and the adjustment method is simple and fast; the second connecting member 3 is installed at the bottom of the seat, and the inclination angle of the seat can be adjusted. After the backrest of the seat is laid down, it can tend to be horizontal, thereby improving the space effect and use comfort of the trunk.

[0038] Embodiment Two

[0039] This embodiment optimizes the displacement adjustment mechanism on the basis of the above embodiment, and in particular provides a specific implementation manner of the first connecting member:

[0040] The lower part of the first connecting member 2 rotates relative to the support member 1, and the upper part of the first connecting member 2 slides along the guide groove 33.

[0041] As Figures 3-5 shown, the main body of the first connecting member 2 is a U-shaped structure. The two sides of the lower part of the first connecting member 2 are respectively pivotally connected to the two sides of the support member 1, and the U-shaped opening of the first connecting member 2 faces the support member 1. Guide grooves 33 are symmetrically arranged on both sides of the second connecting member 3, and one end of the second connecting member 3 close to the support member 1 is the second adjustment end 32; sliding shafts 21 are arranged through both sides of the upper part of the first connecting member 2, and the sliding shafts 21 slide along the guide grooves 33. The first connecting member 2 slides smoothly along the guide grooves 33 through the sliding shafts 21, effectively supporting the second connecting member 3.

[0042] Embodiment Three

[0043] This embodiment provides a seat, which includes the displacement adjustment mechanism in the above embodiment and also includes a seat cushion.

[0044] As Figure 1 , Figure 2 shown, a support frame 5 is arranged at the bottom of the seat cushion. The support frame 5 includes a plurality of pipe fittings 51, and both ends of the second connecting member 3 are respectively connected to the pipe fittings 51.

[0045] The adjustment process of the seat is as follows: When the seat is in a conventional leaning state, the seat cushion has a certain angle with the horizontal direction. The upper part of the first connecting member 2 is located at a position of the guide groove 33 in the second connecting member 3 close to the second adjustment end 32, and the limit assembly 4 is locked with the locking hook 11 of the support member 1; when the backrest of the seat is laid down, the pull rod 43 is pulled, so that the locking tongue 41 of the limit assembly 4 is unlocked from the locking hook 11. The second connecting member 3 is affected by the self-weight of the seat, and the seat cushion rotates forward. The forward tilt of the second connecting member 3 drives the first connecting member 2 to rotate until the first connecting member 2 slides to a position of the guide groove 33 close to the first adjustment end 31, so that the seat cushion and the backrest tend to be horizontal; when the seat needs to be reset, the seat cushion is lifted and rotated to reset. The second connecting member 3 drives the first connecting member 2 to rotate until the first connecting member 2 slides to a position of the guide groove 33 close to the second adjustment end 32, and the locking tongue 41 of the limit assembly 4 is locked with the locking hook 11 again, and the second connecting member 3 stably supports the seat cushion.
