Embodiment 1

[0034] figure 1 It is a structural schematic diagram of a door panel assembly equipped with a door opening limit mechanism in Embodiment 1 of the present invention. figure 2 For the door panel assembly equipped with the door opening limit mechanism figure 1 The cross-section of the A-A' step surface in the middle. image 3 For the door opening limit mechanism along the figure 1 Sectional view of plane B-B' in the middle. Figure 4 It is a schematic structural diagram of the door opening limit mechanism in Embodiment 1 of the present invention. Figure 5 It is a diagram of the working state of the door opening limit mechanism before and after the door is opened in Embodiment 1 of the present invention. like Figure 1 to Figure 5 As shown, Embodiment 1 of the present invention provides a door opening limit mechanism, which includes a fixed seat 2, a pull arm 3, a sliding shaft 7, a sliding shaft mounting seat 1 and a transmission device. One end of the pull arm 3 is hinge...

Embodiment 2

[0050] The difference between this embodiment and embodiment 1 is:

[0051] In this embodiment, the initial limit groove is not needed, because the door lock 14 can realize the limit function of the door panel assembly 18 in the closed state. Further, the position of the limiting groove 6 is set to correspond to the position when the door panel assembly 18 is opened to a maximum angle.

Embodiment 3

[0053] The differences between this embodiment and embodiment 2 are:

[0054] There are multiple limit slots 6, preferably in this embodiment, one position of the limit slot is set at the position when the corresponding door panel assembly 18 is opened at 45 degrees, and the other position of the limit slot is set at the position of the corresponding door panel assembly. Into the position of 18 when it is opened at 90 degrees. The principle that the cam limiting block 10 exits one limiting groove and enters the other limiting groove is the same as the principle of limiting and unlocking described in Embodiment 1.

Abstract

The invention relates to the technical field of limit devices, in particular to a door opening limit mechanism. The mechanism comprises a fixing seat, a pull arm, a sliding shaft, a sliding shaft mounting seat and a transmission device, the pull arm is hinged to the fixing seat, a sliding groove is formed in the pull arm, a limit groove is formed in the sliding groove, the sliding shaft is connected with a door panel assembly through the sliding shaft mounting seat, the sliding shaft can slide along the sliding groove, the sliding shaft is connected with a following cam sleeve, the cam sleeveis arranged inside the sliding groove, a cam limit block on the cam sleeve can enter and exit from the limit groove, the sliding shaft is also connected with a rotating execution device, the transmission device drives the sliding shaft to rotate through the rotating execution device, and the sliding shaft is further connected with a pre-tensioner. The invention further provides the door panel assembly provided with the door opening limit mechanism and an armored vehicle. Compared with the prior art, the door opening limit mechanism has the beneficial effects that the door opening limit mechanism can well limit the door panel assembly, and an operator can conveniently limit, position and release the door panel assembly.

Description

technical field [0001] The invention relates to the technical field of limit devices, in particular to a door opening limit mechanism, a door panel assembly with the mechanism, and an armored vehicle with the door panel assembly. Background technique [0002] At present, the known limit mechanisms for side-opening doors of armored vehicles are generally set in the following ways: [0003] 1. The door opening limit mechanism and the lock are respectively opened. Although this can realize the limit of the armored vehicle door, the operation method of separate opening is obviously not convenient enough, and may even affect the operational response efficiency of the armored vehicle due to lack of convenience. ; [0004] 2. Use a non-positionable door limit mechanism on the door of the armored vehicle. Although this type of non-positionable door limit mechanism can initially achieve the limit effect on the armored vehicle door, when considering the complex application environmen...
