DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that those skilled in the art can easily carry out the present invention.

Figure 2 is a perspective view schematically showing the configuration of the door jamming prevention device according to the present invention, Figure 3 is a cross-sectional view showing an operating state of the door jamming prevention device shown in FIG.

2 and 3, the door jamming prevention device A of the electric vehicle door according to the present invention operates in conjunction with the opening operation of the electric vehicle doors 10 and 10 ', and a pair of doors 10 10 '), a pair of prevention rollers 20 and 20', and the drive means 30 are comprised.

The doors 10 and 10 'are constituted by a pair having the same shape as left and right, and are normally configured to be opened and closed by being accommodated in the space 13 formed between the vehicle body outer wall 11 and the inner wall 12 of the electric vehicle.

In this case, any one of the pair of doors 10 and 10 'is connected to an actuator (not shown) to be opened or closed by a control signal through a control unit (not shown), and the actuator (not shown). According to the operation of the other one door also has a structure that is operated.

Such a structure is a well-known general technique, and a detailed description thereof will be omitted.

Meanwhile, in the gap 14 between the doors 10 and 10 'and the space portion 13 in which the doors are accommodated, prevention rollers 20 and 20' to prevent other objects such as clothes and hair of a passenger from being caught. Is installed.

The prevention roller 20 has a rod shape and is installed to cross the front upper and lower ends of the entrance 14 between the doors 10 and 10 'and the space portion 13 so as to cross the doors 10 and 10'. Will be rotated in reverse rotation when it is opened. This prevents the rollers 20 and 20 ′ from rotating in the reverse direction of the doors 10 and 10 ′ by the reverse rollers. To induce slip naturally.

That is, when the prevention rollers 20 and 20 'are rotated in the forward direction, the doors 10 and 10' may be engaged with the opening direction so that the prevention rollers 20 and 20 'may be pinched to the door gap 14. However, when the prevention rollers 20 and 20 'are rotated in the reverse direction, the objects to be contacted slide outward without being caught by the door gap 14 because the doors 10 and 10' are not related to the opening direction. It can be driven out.

In addition, the prevention rollers 20 and 20 'receives the control signal through the control unit when the opening of the doors 10 and 10' is sensed and the driving means 30 receives the prevention rollers 20 and 20. It is preferable to configure to drive ').

Since the prevention rollers 20 and 20 'installed in the doors 10 and 10' are also installed in pairs, power must be transmitted to each of the prevention rollers 20 and 20 '. Therefore, in the present invention, it is configured to transmit power to the pair of prevention rollers 20 and 20 'by using only one driving motor 31, respectively.

That is, the prevention rollers 20 and 20 'driven by the driving motor 31 should be rotated in reverse rotation to prevent the phenomena of clothes, hair, or other items from the passengers. In order to allow both of the pair of prevention rollers 20 and 20 'to be driven in reverse rotation by using the driving force of the driving motor 31, the belt 33 mounted on the pulley 32 is wound. By mounting through, the pair of prevention rollers 20, 20 'can be rotated in the opposite direction using the driving force of one drive motor 31.

Therefore, when the electric vehicle enters the station and stops and the doors 10 and 10 'are opened, the electric motor is sensed to drive the driving motor 31 in the reverse direction through the control unit and the prevention rollers 20 and 20'. Since the reverse rotation drive is also started in the same direction, clothes or hairs of passengers standing at the doors 10 and 10 'side are rotated through the reverse rotation of the prevention rollers 20 and 20'. Since it is pushed out without being rolled up, it is possible to prevent the jamming occurring in the process of opening the doors 10 and 10 '.

As described above, although the present invention has been described with reference to the above embodiments, it is not necessarily limited thereto, and various modifications may be made without departing from the scope and spirit of the present invention.
