Description

Technical Field

[0001] This utility model relates to the field of automobile body manufacturing technology, and in particular to an anti-fall device for automobile doors. Background Technology

[0002] The car factory uses a door installation station to install car doors. The car doors are placed horizontally. When installing the car door, the staff will start the suction cup. After the suction cup holds the car door, the staff will manually turn the car door from the side to the front. After the door hinge is aligned with the installation hole, the staff will turn off the suction cup and start tightening the bolts. If there is a gas interruption or other malfunction during this process, causing the suction cup to fail, the car door will fall and cause injury to the staff. Utility Model Content

[0003] The purpose of this invention is to provide a fall prevention device for car doors that addresses the shortcomings of existing technologies.

[0004] This utility model is achieved using the following technical solution:

[0005] A vehicle door anti-fall device includes a support device for preventing the vehicle door from falling, a rotating device for rotating the vehicle door from the side to the front, and a reset device for resetting the rotating device; the rotating device is provided at one end of the support device, and the reset device is provided between the support device and the rotating device.

[0006] Preferably, the support device includes at least one transverse bar.

[0007] Preferably, the rotating device includes an angle plate; the first surface of the angle plate is rotatably connected to the first end of the transverse rod.

[0008] Preferably, the reset device includes a reset spring, one end of which is connected to the middle of the transverse rod, and the other end is connected to the second surface of the angle plate.

[0009] Preferably, it also includes a protective device for hooking onto the vehicle door; the protective device includes an elastic pad disposed on the second end of the transverse bar.

[0010] Preferably, the support device further includes at least one diagonal brace for reinforcing the transverse bar.

[0011] Compared with the prior art, the present invention has the following beneficial technical effects:

[0012] This utility model includes a support device for preventing the car door from falling, a rotating device for rotating the car door from the side to the front, and a reset device for resetting the rotating device. If the suction cup fails during the installation of the car door, the car door will not fall, thus protecting personnel and eliminating safety risks. Attached Figure Description

[0016] 1. Horizontal bar; 2. Diagonal brace; 3. Rotating shaft; 4. Fixing block; 5. Angle steel; 6. Return spring; 7. Polyurethane block. Detailed Implementation

[0017] like Figure 1 As shown: A car door anti-fall device includes a support device for preventing the car door from falling, a rotating device for rotating the car door from the side to the front, and a reset device for resetting the rotating device; the rotating device is provided at one end of the support device, and the reset device is provided between the support device and the rotating device.

[0018] The support device includes at least one transverse rod 1. Preferably, there is one transverse rod 1.

[0019] The rotating device includes an angle plate; the first surface of the angle plate is rotatably connected to the first end of the transverse rod. Preferably, the angle plate is made of angle steel 5, and the first surface of the angle steel 5 is fixed to a block 4 on the transverse rod, with the rotating shaft 3 rotatably connected to the block 4. The angle steel 5 can be fixed to the car door mounting device inside the vehicle. With the angle steel 5 stationary, the transverse rod 1 drives the car door to rotate from the side to the front, preventing the suction cup from failing during the door installation process, which could cause the door to fall and injure personnel.

[0020] The reset device includes a reset spring 6, one end of which is connected to the middle of the transverse rod 1, and the other end is connected to the second surface of the angle plate. Preferably, the reset spring 6 is fixedly connected to the second surface of the angle steel 5. Reset via the reset spring 6 eliminates the need for manual operation, making it simple and reliable.

[0021] It also includes a protective device for hooking onto the vehicle door; the protective device includes a resilient pad, which is located on the second end of the transverse bar. The resilient pad is made of polyurethane block 7, used to hook onto the vehicle door while preventing scratches to the door.

[0022] The support device also includes at least one diagonal brace 2 for reinforcing the transverse rod. Preferably, the two ends of the diagonal brace 2 are fixedly connected to the pivot 3 and the transverse rod 1, respectively; the three together form a triangular stable structure.

[0023] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
