[0018] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0019] The first embodiment of the present application is:

[0020] See also Figures 1 to 3 ,in, Figure 1 The utility model is a schematic structural diagram of the anti-collision mechanism of the third row of four-part folding seats. Figure 2 The utility model is a side view of the anti-collision mechanism of the third row of four-part folding seats. Figure 3 The utility model Figure 2 The utility model provides an anti-collision mechanism for a third row of four-part folding seats: comprising a seat frame 101, a backrest frame 102 and a hook assembly, wherein the hook assembly comprises a fixed seat 103, a rotating seat 104, a first limit block 105, a second limit block 106, a connecting spring 107 and a connecting rod 108, wherein the fixed seat 103 has an arc surface 109, and the rotating seat 104 has a rounded corner 110.

[0021] According to this specific embodiment, the backrest frame 102 is rotatably connected to the seat frame 101 and is located on one side of the seat frame 101. The backrest frame 102 and the seat frame 101 are rotatably arranged, and an adjuster is arranged at the connection. The backrest frame 102 can be folded on the seat frame 101 by unlocking the adjuster, and a seat cushion can be covered on the backrest frame 102 and the seat frame 101 to form a car seat.

[0022] The fixed seat 103 is fixedly connected to the seat frame 101 and is located on the side of the seat frame 101 close to the backrest frame 102. The rotating seat 104 is rotatably connected to the fixed seat 103 and is located below the fixed seat 103. The first limit block 105 is fixedly connected to the fixed seat 103 and is located on the side of the fixed seat 103 close to the rotating seat 104. The second limit block 106 is fixedly connected to the rotating seat 104 and is located on the outer wall of the rotating seat 104. The two ends of the connecting spring 107 are respectively connected to the first limit block 105 and the second limit block 106. The fixed seat 103 is welded and fixed to the lower part of the seat frame 101, and is rotatably connected to the rotating seat 104 at the lower part through a pin shaft. The first limit block 105 is integrally formed with the fixed seat 103. The second limit block 106 is fixed to the outer wall of the rotating seat 104. The first limit block 105 and the second limit block 106 are connected by the connecting spring 107.

[0023] Secondly, the number of the fixed seats 103 and the number of the rotating seats 104 are two, respectively. The two fixed seats 103 are arranged opposite to each other, and the two rotating seats 104 are arranged opposite to each other. The two ends of the connecting rod 108 are respectively fixedly connected to the two rotating seats 104. The two groups of the fixed seats 103 and the rotating seats 104 are arranged opposite to each other under the seat frame 101, and the seat frame 101 is installed together to ensure stable installation. The connecting rod 108 is fixed between the two rotating seats 104, and the two rotating seats 104 can be used simultaneously through the connecting rod 108.

[0024] Meanwhile, the arc surface 109 is located on the side of the rotating seat 104 away from the seat frame 101. After the seat frame 101 is turned over, the fixed seat 103 has the arc surface 109 on the side facing outward, which is beneficial for dispersing stress and reducing stress concentration when the arc surface 109 contacts an object, thereby reducing the risk of damage to the object.

[0025] In addition, the rounded corners 110 are located at the outer edges of the rotating base 104. The outer edges of the rotating base 104 are all configured as rounded corners 110 to avoid rubbing against objects.

[0026] Using the anti-collision mechanism of the third row of four-folding seats of this embodiment, after the seat frame 101 is completely folded, the fixed seat 103 faces upward and the rotating seat 104 faces outward. At this time, the rotating seat 104 rotates due to gravity, and the connecting spring 107 pulls the first limit block 105 and the second limit block 106, so that the rotating seat 104 remains fixed, avoiding the rotating seat 104 from shaking during the movement of the vehicle and causing collision, thereby avoiding damage to objects.

[0027] The second embodiment of the present application is:

[0028] Based on the first embodiment, please refer to Figure 1 and Figure 2 ,in, Figure 1 The utility model is a schematic structural diagram of the anti-collision mechanism of the third row of four-part folding seats. Figure 2 The side view of the anti-collision mechanism of the third row of four-part folding seats of the utility model. The hook assembly of this embodiment further includes a hook 201.

[0029] According to this specific embodiment, the hook 201 is located inside the rotating seat 104. The hook 201 is arranged in one of the rotating seats 104 and can rotate to hook or unhook the ground of the car.

[0030] Using the anti-collision mechanism of the third row four-part folding seat of the present embodiment, when the seat needs to be flipped, the seat frame 101 and the backrest frame 102 are unlocked by the adjuster, so that the backrest frame 102 is flipped on the seat frame 101, and then the drawstring is pulled to drive the drawstring to move in the protective cover, and the hook 201 is pulled to make the hook 201 hook with the car ground, so that one side of the seat frame 101 can be separated from the car ground, and then the second locking assembly is unlocked to flip the seat frame 101 on the mounting seat until the fixing seat 103 is facing upward, exposing a large amount of space for placing large goods, which is easy to operate and meets the user's multifunctional and multi-purpose needs for both carrying goods and pulling people.

[0031] What is disclosed above is only one or more preferred embodiments of the present application, and cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
