Description

Technical Field

[0001] This utility model relates to the technical field of sliding doors, and in particular to an arc-shaped sliding door. Background Technology

[0002] Most existing cars lack a rear bumper for the driver, making it difficult to separate passengers and the driver, seriously affecting driver safety. To provide a better driving environment, most cars now have a rear bumper installed behind the driver's seat. However, this is usually a semi-enclosed bumper, which still cannot effectively separate passengers and the driver, posing certain safety hazards. Therefore, a full-coverage rear bumper structure has emerged. However, most existing full-coverage rear bumper structures use hinges to install the doors, which requires space during opening and closing, such as the passenger aisle. Especially when the driver opens the door, passengers cannot pass through, easily causing congestion when boarding.

[0003] In view of this, the inventor specifically designed an arc-shaped sliding door, which led to this invention. Utility Model Content

The second slide rail 40 extends upward from the side near the sliding door body 10 with a first extension and extends downward with a second extension. The upward-extending first extension, in particular, can block some dust from entering between the sliding door body 10 and the first slide rail 20. Combined with the dustproof strips 60, the dustproof effect is even better.

[0032] Please refer to details. Figure 1 , 23, 4. The arc-shaped sliding door is mounted on bracket 01. Bracket 01 includes frame 02, a first support 03 mounted on frame 02 for mounting the first slide rail 20, and a second support 04 mounted on frame 02 for mounting the second slide rail 40. Both the first support 03 and the second support 04 are constructed using a combination of tubular and sheet-like components to enhance structural stability and load-bearing capacity. Specifically, the sheet-like component is first mounted on frame 02, then the tubular component is mounted on the sheet-like component, and the first slide rail 20 and the second slide rail 40 are secured together with bolts.

[0033] Please refer to details. Figure 2 , 3 The sliding door body 10 has a first groove 11 on its surface and a first connecting hole 12 at its top end that communicates with the first groove 11. The first connecting rod part 312 can pass through the first connecting hole 12. A first locking nut 36 and a second locking nut 37 are also provided to install the first connecting rod part 312 on the sliding door body 10 and to adjust the position of the first roller 33. Specifically, the first locking nut 36 is located in the first groove 11 and screwed to the first connecting rod part 312, and the second locking nut 37 is located at the top of the sliding door body 10 and threaded to the first connecting rod part 312. When adjustment is needed, loosen the first locking nut 36 or the second locking nut 37, move the entire first sliding device 30 up or down accordingly, and then tighten the second locking nut 37 or the first locking nut 36 to achieve quick adjustment. Furthermore, wear-resistant washers 38 are provided between the first locking nut 36 and the sliding door body 10, and between the second locking nut 37 and the sliding door body 10, to prevent wear between the first locking nut 36 / second locking nut 37 and the sliding door body 10.

[0034] Please refer to details. Figure 2 , 4 The sliding door body 10 also has a second groove 13 on its surface, and a mounting block 14 is provided at the opening of the second groove 13 on the surface of the sliding door body 10. The second groove 13 also connects to the bottom of the sliding door body 10 to facilitate installation or adjustment from the bottom.

A third locking nut and a fourth locking nut are also provided to install the second connecting part 511 on the mounting block 14 of the sliding door body 10 and to adjust the position of the second roller 53. Specifically, the third locking nut is located inside the second groove 13 and screwed to the second connecting part 511, and the fourth locking nut is located outside the mounting block 14 and threaded to the second connecting part 511. When adjustment is required, loosen the third locking nut or the fourth locking nut, move the entire second sliding device 50 outward or inward accordingly, and then tighten the fourth locking nut or the third locking nut to achieve quick adjustment.

[0035] Please refer to details. Figure 7 The sliding door 10 is also equipped with a door lock device 70, and the frame 02 is equipped with a door lock seat 05. Both sides of the door lock device 70 are equipped with hook grooves 71. The hook grooves 71 can hook the door lock seat 05. Therefore, regardless of whether the door is open or closed, the hook grooves 71 can hook the door lock seat 05 to prevent the sliding door 10 from moving.

[0036] When installing the sliding door body 10 of this utility model, the two first sliding devices 30 and the two second sliding devices 50 are first installed on the sliding door body 10. At the same time, the positions of the first roller 33 and the second roller 53 are adjusted according to the positions of the first slide rail 20 and the second slide rail 40. The sliding door body 10 can then be installed in place from the side wall of the first slide rail 20 and the second slide rail 40.

[0037] In summary, the arc-shaped sliding door of this utility model achieves the sliding of the door body by setting a first sliding rail and a second sliding rail, and by using the first sliding device in conjunction with the second sliding device. Therefore, it will not occupy the passage during the opening and closing process.
