Description

Technical Field

[0001] The utility model relates to the technical field of passenger vehicles, in particular to a rear hatch door structure. Background Art

[0002] With the development of bus manufacturing technology, the structural layout of vehicles has also been improved in a more convenient and safe direction. For the rear cabin of the vehicle, the traditional hatch has a hinge on the top side of the door body, and the hatch is an upward flip-up door that opens from the bottom to the top, but this type of rear door that rises to a high position requires force to open and close.

[0003] For new energy vehicles, the convenience and stability of the rear hatch are crucial. The basic requirement for the hatch lock body is that the door lock device has a guiding and positioning function for the door when opening and closing. When the door is in a fully locked state, the door lock can withstand a certain longitudinal load, lateral load and impact inertia force, so that the door lock will not fail due to car collision, rollover, or bumps. At the same time, the hatch door should be convenient and flexible when opening and closing. However, the opening and closing design of the rear hatch door of current buses is relatively simple. The traditional rear hatch door design adopts a flip hinge or folding hinge structure, which has poor operation convenience and flexibility, and can no longer meet the structural layout requirements of new energy vehicles. Utility Model Content

[0004] The utility model aims to provide a rear hatch structure, aiming to improve the problem that the flexibility and convenience of the existing rear hatch of passenger cars are relatively poor.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A rear hatch door structure comprises a door body, a first connecting rod, a second connecting rod and a gas spring;

[0007] A cross bar is arranged at the top of the door body, a frame is arranged at the middle of the door body, the cross bar and the frame are connected to the vehicle frame, a zipper door is arranged on the door body, a lock body is arranged in the zipper door, and the lock body is arranged on the frame;

[0008] There are two first connecting rods, which are arranged on both sides of the door body. One end of the first connecting rod is hinged to the frame body, and the other end is connected to the bottom of the door body.

[0009] There are two second connecting rods, which are arranged on both sides of the door body. One end of the second connecting rod is hinged to the cross rod, and the other end is connected to the middle part of the side of the door body. The second connecting rod is fixed to the frame through a latch mechanism, and the latch mechanism is connected to the lock body. The lock body controls the opening and closing of the latch mechanism.

[0010] There are two gas springs, one end of which is connected to the vehicle frame, and the other end is connected to an end of the first connecting rod close to the frame body. The gas spring pushes the other end of the first connecting rod to tilt upward to drive the door body to move upward.

[0011] Preferably, the hinged end of the second connecting rod and the cross rod is a bent arm, and the arc-shaped opening of the bent arm is opposite to the door body.

[0012] Preferably, a third connecting rod is further included, one end of the third connecting rod is connected to the second connecting rod and fixed to the door body, and the other end of the third connecting rod is connected to the first connecting rod and fixed to the bottom of the door body.

[0013] Preferably, a charging compartment door is also provided on the door body.

[0014] Preferably, the zipper door and the charging compartment door are provided with handles.

[0015] Preferably, the first connecting rod is V-shaped, the V-shaped opening of which is arranged relative to the door body, and the V-shaped inflection point is hinged to the frame body.

[0016] Preferably, sealing strips are provided at the bottom and the top of the door body, and the sealing strips are strip-shaped grooves with openings arranged relative to the door body.

[0017] After adopting the above technical solution, the utility model has the following advantages compared with the background technology:

[0018] 1. In the utility model, when the door body is not opened, it is fixed to the frame body by the second connecting rod. When the lock body controls the latch mechanism to open, the second connecting rod is separated from the frame body, and the door body has no fixed binding end. The hinged ends of the first connecting rod and the second connecting rod rotate, and the non-hinged ends are pushed outward, so that the door body pops out. At the same time, under the rotation of the first connecting rod and the second connecting rod, the non-hinged end is tilted upward to lift the door body, thereby realizing the upward movement and opening of the door body. This opening method is flexible and labor-saving, and the hatch door can be opened and closed only by controlling the lock body.

[0019] 2. In the utility model, a third connecting rod is also included, and both ends of the third connecting rod are respectively connected to the raised ends of the first connecting rod and the second connecting rod, and the third connecting rod is fixed to the door body. When the first connecting rod and the second connecting rod rotate, the third connecting rod stably translates outward or upward, thereby driving the door body to translate outward or outward stably, avoiding the door body from tilting when opening, and maintaining the stability of the door body opening.
