Detailed description of the embodiments

[0016] With reference to the Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7 to Fig. 8 The present utility model provides a furniture folding device with improved closing stability, comprising a housing 1, a mounting element 2, a swivel arm mechanism 3 and a damping mechanism 4;

[0017] As in Fig. As shown in Figure 7, the housing 1 is designed for permanent mounting on the cabinet body. The mounting element 2 is used to connect it to the cabinet door and includes a mounting seat for a secure connection to the cabinet door and a connecting seat for connecting it to the swivel arm mechanism 3.

[0018] As in Fig. 1 and Fig. As shown in Figure 2, the pivot arm mechanism 3 is pivotally connected to the housing 1 and the mounting element 2, respectively, so that the mounting element 2 can be folded relative to the housing 1. In the present embodiment, the pivot arm mechanism 3 comprises a first pivot arm 31, a second pivot arm 32, a third pivot arm 33, and a fourth pivot arm 34, wherein the first pivot arm 31, the second pivot arm 32, the third pivot arm 33, and the fourth pivot arm 34 together form a four-bar linkage mechanism that serves to guide the folding movement of the mounting element 2 relative to the housing 1.

[0019] As in Fig. 2 and Fig. As shown in Figure 3, the first pivot arm 31 has a guide section 311. In the present embodiment, a roller 35 is rotatably arranged on the first pivot arm 31, the roller 35 together with the edge of the first pivot arm 31 forming the guide section 311; the rotatable arrangement of the roller 35 on the first pivot arm 31 reduces the frictional resistance during sliding interaction with the guide rail 411.

[0020] As in Fig. 4 and Fig. As shown in Figure 5, the damping mechanism 4 serves to provide a damping force when the cabinet door is closed. The damping mechanism 4 comprises an actuating element 41 and a damper 42. The upper end of the actuating element 41 is rotatably connected to the housing 1, one side edge of the actuating element 41 has the guide rail 411, and the other side edge is rotatably connected to one end of the damper 42. The other end of the damper 42 is rotatably connected to the housing 1 or a mounting seat (not shown).

[0021] In the present embodiment, the guide rail 411 is designed as a projection, and the side edges of the guide rail 411 are provided with a chamfer to gently introduce the guide section 311 into the guide rail 411, wherein the guide rail 411 interacts with the guide section 311 in a form-fitting manner.

[0022] As in Fig. 4 and Fig. As shown in Figure 5, the damping mechanism 4 further comprises an adjustment assembly, wherein the adjustment assembly includes an adjustment spindle 43 and a slider 44. The adjustment spindle 43 is rotatably mounted on the actuating part 41, and the slider 44 engages the adjustment spindle 43 in threaded engagement and is rotatably connected to the damper 42. When the adjustment spindle 43 is rotated, it drives the slider 44 to a linear movement in the axial direction of the adjustment spindle 43, thereby changing the initial position of the damper 42 and altering the timing and magnitude of the damping action.

[0023] As in Fig. As shown in Figure 6, the damping mechanism 4 further comprises a quick-change seat 45, wherein the quick-change seat 45 has a receiving groove 451 and the cylinder housing end of the damper 42 is spring-loaded and engaged in the receiving groove 451; the front of the receiving groove 451 has an opening that facilitates the insertion of the cylinder housing end of the damper 42; the rear wall of the receiving groove 451 has a through-slot 452 so that, in the event of a defect of the damper 42, the user can guide a tool through the through-slot 452 to push the damper 42 out of the receiving groove 451 and enable quick replacement.

[0024] The telescopic end of the damper 42 has a rotating part 421, which is designed as a spherical structure; the slider 44 has a movement groove 441 adapted to the rotating part 421, the rotating part 421 being rotatably arranged in the movement groove 441. The spherically designed rotating part 421 can, on the one hand, rotate freely in the movement groove 441, so that the damper 42 can adapt to the angular changes between the working part 41 and the slider 44 during the damping process, and the telescopic end of the damper 42 always maintains a stable connection with the slider 44; on the other hand, the spherical structure enables quick installation and removal, since when replacing the damper 42, the rotating part 421 only needs to be released from the movement groove 441 without having to disassemble any other components.

[0025] This quick-change design allows the user to quickly replace the damper 42 if it becomes damaged or fails after prolonged use, without complex tools and without disassembling the entire damping mechanism, which significantly improves ease of maintenance and efficiency.

[0026] As in Fig.As shown in Figure 7, when the cabinet door is closed, the guide section 311 slidably interacts with the guide rail 411 to guide the pivot arm mechanism 3 into relative motion along the effective end of the damping mechanism 4; specifically, when the cabinet door is closed, the guide section 311 on the first pivot arm 31 comes into contact with the guide rail 411 on the effective part 41 up to a certain angle and slides along the guide rail 411; during the sliding process, the guide rail 411 exerts a guiding and limiting effect on the guide section 311 and ensures that the pivot arm mechanism 3 moves along a predetermined path, thereby maintaining stable interaction with the damping mechanism 4.Simultaneously, the pivot arm mechanism 3, via the guide section 311, pushes the actuating element 41 to rotate about its pivot point at the upper end with the housing 1. The other side edge of the actuating element 41 compresses the damper 42, and the damper 42 generates damping resistance, thus achieving a soft closing of the door. When the cabinet door is opened, the pivot arm mechanism 3 moves in the opposite direction, the guide section 311 disengages from the guide rail 411, and under the restoring force of the damper 42, the actuating element 41 returns to its initial position and is ready for the next closing damping cycle.

[0027] The user can adjust the starting position of the damper 42 as needed via the adjusting spindle 43 in order to adapt the device to cabinet doors of different weights or to different damping requirements.
