AI Technical Summary

Problems solved by technology

Therefore, the opening and closing process and locking process of the opening and closing mechanism often require different actions to complete, and two or more different cylinders are required to complete different actions to meet the requirements, which leads to the mechanical mechanism and automatic control principle of the opening and closing mechanism. It is more complicated, the corresponding cost is also high, and its reliability is also reduced

Embodiment 1

[0057] Such as Figure 5 As shown, the limit stopper 9 has an elastic member 12, so that the protrusion 901 can produce elastic deformation (rather than rigid contact) after contacting the receiving portion 902; thereby producing self-locking.

[0058] Optionally, the elastic member 12 is disposed on the protrusion 901 or on the receiving portion 902 .

[0059] Optionally, the elastic member 12 is a stretchable contact portion 9011, preferably disposed on the protrusion 901, such as Figure 5 shown. When the receiving part 902 is in contact with the raised contact part 9011, the contact part 9011 is compressed, and when the receiving part 902 leaves the raised contact part 9011, the contact part 9011 recovers.

[0060] The stretchable contact portion 9011 can be realized by using a spring principle, or can be made of elastic materials, such as rubber and other materials.

[0061] In this embodiment, due to the elasticity of the limit stop 9, the locking device, the support ...

Embodiment 2

[0071] Such as Figure 7 As shown, the chute 5 is provided with a deformable elastic member 12 , and when the locking device 2 is substantially perpendicular to the chute 5 , the elastic member 12 is compressed.

[0072] Optionally, the elastic member 12 is made of deformable and wear-resistant material, and is installed in the sliding groove 5 . Such as Figure 7 As shown, when the locking device 2 is approximately perpendicular to the sliding groove 5, the elastic member 12 is compressed to the maximum amount, thereby deforming; in the figure, the elastic member 12 is pressed into a concave shape by the second end 202 of the locking device. When the second end 202 of the locking device continues to move upward and rightward, the elastic member 12 recovers in whole or in part, thereby realizing self-locking.

[0073] or optionally, as in Figure 8 As shown, the elastic member 12 forms a first gap 16 in the slide groove, and the width of the first gap is smaller than the di...

Embodiment 3

[0078] Such as Figure 9 and Figure 10 As shown, the second end 202 of the locking device is provided with an elastic member 12, and when the locking device 2 is substantially perpendicular to the slide groove 5, the elastic member 12 is compressed.

[0079] Optionally, the elastic member 12 is made of deformable and wear-resistant material, and is at least installed at the contact position between the second end 202 of the locking device and the slide groove 5 . Optionally, the elastic member 12 is an elastic roller 19 fitted on the second end 202 of the locking device, which can be made of conventional elastic and wear-resistant materials such as rubber, and can rotate relative to the second end 202 .

[0080] When the locking device 2 is approximately perpendicular to the chute 5, the elastic member 12 is compressed to the maximum by the chute 5, thereby deforming; as Figure 9 As shown, the place where the roller 19 is close to the chute 5 (the top left of the roller) i...

Abstract

The invention relates to an opening and closing mechanism and a train with the opening and closing mechanism. The opening and closing mechanism comprises a driving device, a locking device and a supporting arm, wherein the driving device is connected with the locking device and used for driving the locking device to rotate, the first end of the locking device is rotatably mounted on a bottom plate, a sliding groove is formed in the supporting arm, the second end of the locking device is located in the sliding groove in a sliding mode, the first end of the supporting arm is rotatably mounted on the bottom plate, the second end of the supporting arm is connected with a fairing; the driving device drives the locking device to rotate, and the locking device drives the supporting arm to rotate through the sliding groove, so that the supporting arm opens or closes the fairing.

Description

technical field [0001] The application belongs to the technical field of mechanical manufacturing, and in particular relates to an opening and closing mechanism and a train with the opening and closing mechanism. Background technique [0002] In order to realize the reconnection or return rescue on the train of the high-speed EMU, the front-end opening and closing mechanism is usually installed at the head of the train set. The front-end opening and closing mechanism is an important part of the EMU. During the normal operation of the EMU (that is, in the non-reconnected state), the opening and closing mechanism is in the closed state. At this time, the front fairing hatch is closed, so that the high-speed EMU has a good The aerodynamic shape prevents the entry of blades, dust, ice and snow, and at the same time protects the couplers and other facilities inside the front fairing; in the case of return or rescue, the opening and closing mechanism can be opened automatically or...
