Description

Technical Field

[0001] The utility model relates to the technical field of automobile doors, in particular to an automatic opening and closing bracket for automobile doors. Background Art

[0002] The doors of a car include side doors and rear doors. The side doors are mainly used for getting in and out of the car, while the rear doors are mainly used for loading cargo. Existing brackets support the doors to facilitate loading cargo into the trunk. The rear door flips upward when opened, and a person needs to push hard to flip the door upward. In addition, the rear door flips downward by a large amplitude when closed, which increases the inertia of the rear door's swing, resulting in greater vibration caused by the collision between the rear door and the car body when closed, thereby causing loosening and damage to the internal parts of the rear door.

[0006] As a further optimization of the present technical solution, the mounting base includes a mounting base, a bolt hole, a tension spring, and a buffer pad. The mounting base is fixedly connected to the end face of the engaging base. Three bolt holes are provided, and the bolt holes are arranged on the end face of the mounting base. Two tension springs are provided, and the tension springs are respectively fixedly connected to the end faces of the mounting base. The tension spring is connected to the front end face of the fixing base, and the buffer pad is embedded in the middle position of the mounting base.

[0007] As a further optimization of the present technical solution, the buffer pad includes an embedded seat, a friction groove, a rubber seat, a buffer groove, and a friction block. The embedded seat is embedded in the end surface of the mounting base plate, and there are more than five friction grooves, which are arranged on the bottom end surface of the embedded seat. The rubber seat is fixedly connected to the top of the embedded seat, and there are two buffer grooves, which are respectively located on the inner side end surfaces of the rubber seat. There are five friction blocks, which are arranged on the top end surface of the rubber seat.

[0008] As a further optimization of the technical solution, the width of the end surface of the rubber seat gradually decreases from the bottom to the upper end.

[0009] As a further optimization of the technical solution, the width of the buffer groove gradually decreases from the upper and lower ends to the middle position. Beneficial Effects

[0010] Compared with the prior art, the automatic opening and closing bracket for automobile doors of the utility model has the following advantages:

[0011] The utility model releases the lock of the rear door and allows the tension of the extension spring to assist the rear door to open, thereby achieving the purpose of automatically opening the door.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the preferred implementation scheme of the present invention is further described below in conjunction with specific implementation schemes and accompanying drawings. Example

[0019] See also Figure 1-Figure 4 The utility model provides an automatic opening and closing bracket for a car door, which comprises a fixing seat 1, a fixing hole 2, and a main body 3. The fixing holes 2 are arranged on both side end surfaces of the fixing seat 1, and the main body 3 is engaged with the front end of the fixing seat 1.

[0020] The main body 3 includes a snap-fit ​​seat 31 , a snap-fit ​​rod 32 , and a mounting seat 33 . The snap-fit ​​seat 31 is provided with a snap-fit ​​rod 32 on the end surface thereof. The snap-fit ​​rod 32 is snap-fitted to the end surface of the fixing seat 1 . The mounting seat 33 is connected to the front end surface of the snap-fit ​​seat 31 .

[0021] The mounting seat 33 includes a mounting base plate 331, bolt holes 332, a tension spring 333, and a buffer pad 334. The mounting base plate 331 is fixedly connected to the end surface of the engaging seat 31. There are three bolt holes 332, and the bolt holes 332 are arranged on the end surface of the mounting base plate 331. There are two tension springs 333, and the tension springs 333 are respectively fixedly connected to the end surfaces of the mounting base plate 331. The tension spring 333 is connected to the front end surface of the fixing seat 1, and the buffer pad 334 is embedded in the middle position of the mounting base plate 331.

[0022] The buffer pad 334 includes an embedded seat a1, a friction groove a2, a rubber seat a3, a buffer groove a4, and a friction block a5. The embedded seat a1 is embedded in the end surface of the mounting base 331. There are more than five friction grooves a2, and the friction grooves a2 are arranged on the bottom end surface of the embedded seat a1. The rubber seat a3 is fixedly connected to the top of the embedded seat a1. There are two buffer grooves a4, and the buffer grooves a4 are respectively located on the inner side end surfaces of the rubber seat a3. There are five friction blocks a5, and the friction blocks a5 are arranged on the top end surface of the rubber seat a3.

[0023] The width of the end surface of the rubber seat a3 gradually decreases from the bottom to the upper end.

[0024] The width of the buffer groove a4 gradually decreases from the upper and lower ends to the middle position.

[0025] Working principle: when the bracket is to be installed on the car door, the fixing seat 1 can be positioned on the car body, and then fixed to the car body by passing the bolt through the end face of the fixing hole 2, and then the end face of the main body 3 is fitted to the rear door and fixed to the end face of the rear door by passing the bolt through the bolt hole 332 for installation, so that the rear door can be supported by the bracket. When the rear door is to be opened, the lock of the rear door can be loosened to allow the tension of the tension spring 333 to assist the rear door to open, so as to achieve the purpose of automatically opening the door. When closing the door, the rear door can be pressed downward to allow the door to close automatically by inertia, and the vibration generated during closing can be squeezed by squeezing the end face of the rubber seat a3 into the buffer groove a4 to cause deformation for shock absorption, thereby reducing the vibration of the rear door and preventing the parts in the rear door from loosening.
