Description

Technical Field

[0001] The utility model relates to the technical field of seats, in particular to a split seat. Background Art

[0002] At present, the car seats on the market are divided into one-piece seats and split seats; one-piece seats are made of multiple seat bodies to form an integral structure. When they need to be flipped, multiple seat bodies must be flipped at the same time. At this time, if you want to accommodate passengers and large luggage, you cannot do both at the same time, which makes operation difficult and inconvenient; split seats are made of multiple seat bodies that are made separately. When you need to flip and hide large luggage, you only need to flip some of the seat bodies, without flipping multiple seat bodies at the same time, and the other seats can continue to accommodate passengers; however, the current split seats generally achieve flipping by installing a pivot shaft on the seat body; when the user needs to flip the seat, he manually applies a thrust after unlocking to make the seat flip over; when the user needs to flip up the seat, he needs to lift the seat with force and then lock it. There is no power assist during the operation, which makes the lifting operation more laborious, and the convenience performance needs to be improved. Utility Model Content

[0051] The first axis 10 is the central axis of the first rotating shaft 322 , and the second axis 20 is the central axis of the second rotating shaft 332 .

[0052] The mounting frame 311 is provided with a first mounting hole 31121, and the first rotating shaft 322 is passed through the first mounting hole 31121; the mounting frame 311 is provided with a second mounting hole 31131, and the second rotating shaft 332 is passed through the second mounting hole 31131. The first mounting hole 31121 and the second mounting hole 31131 can realize the assembly between the mounting frame 311, the first connecting member 32 and the second connecting member 33, which helps to reduce the occupied space of the flip mechanism 3 and has a compact structure.

[0053] The first turning assist assembly 34 includes a first gear 341, a second gear 342, a chain 343, a stopper 344 and an elastic member 345. The first gear 341 is sleeved and fixed on the first rotating shaft 322, the second gear 342 is sleeved and fixed on the first shaft sleeve 313, the second gear 342 is connected to the first gear 341 through the chain 343, the stopper 344 is fixedly connected to the first shaft sleeve 313, and the stopper 344 has a first stopper wall 34421 and a second stopper wall 34422. The limiting wall 34422, the elastic member 345 is sleeved on the first shaft sleeve 313, and the two ends of the elastic member 345 have a first action arm 3451 and a second action arm 3452 respectively; the mounting frame 311 has a first supporting wall 33142 and a second supporting wall 31111, the first supporting wall 33142 and the first limiting wall 34421 are located on the first side of the mounting shaft 312, and the second supporting wall 31111 and the second limiting wall 34422 are located on the second side of the mounting shaft 312. The limiting member 344 has: a first position, at which the first action arm 3451 abuts against the first supporting wall 33142, and the second action arm 3452 abuts against the second limiting wall 34422; a second position, at which the first action arm 3451 abuts against the first limiting wall 34421, and the second action arm 3452 abuts against the second supporting wall 31111.

[0054] In this embodiment, when the limiting member 344 is placed in the first position, the seat body is in the stowed state; when the limiting member 344 is placed in the second position, the seat body is in the unfolded state. Figure 1 , Figure 3 and Figure 6 The limiting member 344 of the first flip assist assembly 34 is placed in the first position, and the first seat body 1 is in the stored state; the limiting member 344 of the second flip assist assembly 35 is placed in the second position, and the second seat body 2 is in the unfolded state.

[0055] When the first seat body 1 is in the storage state, the limiting member 344 is in the first position, the first action arm 3451 abuts against the first support wall 33142, the second action arm 3452 abuts against the second limiting wall 34422, and the elastic member 345 accumulates elastic potential energy. When the first seat body 1 is driven to rotate around the first axis 10 by the first connecting member 32 to unfold the seat body, the rotation of the first connecting member 32 is transmitted to the first shaft sleeve 313 through the first gear 341, the chain 343 and the second gear 342 and drives the first shaft sleeve 313 to rotate. The first shaft sleeve 313 drives the limiting member 344 to rotate and causes the elastic member 345 to release the spring potential energy. The released elastic potential energy can be transmitted to the first connecting member 32 through the limiting member 344, the second gear 342, the chain 343 and the first gear 341 to offset part of the gravity potential energy when the seat body 200 is flipped upward, thereby reducing the user's effort to flip the seat to play a power-assisting role.

[0056] When the limit member 344 flips to the preset position, the elastic member 345 returns to the preset state, which can be the natural extension state of the elastic member 345, that is, the state in which the elastic member 345 does not accumulate elastic potential energy, or the minimum compression state of the elastic member 345, that is, the state in which the elastic member 345 accumulates the minimum elastic potential energy.

[0057] When the limiting member 344 passes the preset position and needs to be flipped from the preset position to the second position, the first action arm 3451 is separated from the first support wall 33142 and abuts against the first limiting wall 34421, the second action arm 3452 is separated from the second limiting wall 34422 and abuts against the second support wall 31111, and the elastic member 345 accumulates elastic potential energy to offset part of the gravitational potential energy when the first seat body 1 is flipped downward, slowing down the descending speed of the first seat body 1 to improve the maneuverability of the first seat body 1 when it is flipped, until the limiting member 344 is in the second position and the first seat body 1 is in the unfolded state.

[0058] The elastic member 345 can be a torsion spring, a tension spring, a compression spring, or any other elastic member that can assist in the flipping process of the flipping mechanism by storing and releasing elastic potential energy, and is not limited here.

[0059] The structure of the second flip assist component 35 is similar to that of the first flip assist component 34, the assembly of the second flip assist component 35 and the second connecting member 33 is similar to the assembly of the first flip assist component 34 and the first connecting member 32, and the assembly of the second flip assist component 35 and the mounting member 31 is similar to the assembly of the first flip assist component 34 and the mounting member 31, which will not be elaborated here.

[0061] The third mounting portion 3314 defines a through hole 33141 , and the first supporting wall 33142 is disposed in the through hole 33141 .

[0062] Specifically, in the present embodiment, the through hole 33141 is a bar-shaped through hole 33141 , and the second supporting wall 31111 is an inner wall of one side of the bar-shaped through hole 33141 .

[0063] In some other embodiments, the through hole 33141 may also be a through hole of any shape, such as a circular through hole, an elliptical through hole, a waist-shaped through hole, a polygonal through hole, etc., which is not limited here.

[0064] See also Figure 3 , Figure 5 , Figure 6 and Figure 8 The limiting member 344 provided in the embodiment of the utility model includes a fixing portion 3441 and a limiting portion 3442.

The first motor 4 is used to realize the automatic flipping of the first seat body 1, further improving the convenience of use. At the same time, since the first flipping assist component 34 can play a role in offsetting part of the gravitational potential energy of the first seat body 1 during the process of the first seat body 1, the output power required by the first motor 4 to flip the first seat body 1 can be reduced, so that the first motor 4 with smaller output power and smaller volume can be used to realize the automatic flipping of the heavier first seat body 1.

[0066] The split seat further includes a second motor 5, which is connected to the side of the second seat body 2 away from the mounting member 31 and can drive the second seat body 2 to rotate around the second axis 20.
