B7 ___ V. Description of the invention (!) [Application fields in the industry] (Please read the precautions on the back before filling out this page) The present invention relates to the opening and closing device for railway vehicle doors, especially for the opening and closing devices for railway vehicles. Door opening and closing devices for opening and closing driving of the left and right door bodies of a railway vehicle by an electric motor. [Prior Art] Conventionally, although the driving source of an apparatus for opening and closing a door of a railway vehicle generally uses an air-pressure fluid, in recent years, from the standpoint of reducing driving sound, controlling responsiveness, and improving maintainability, The development of a door drive device using an electric motor as a drive source is ongoing. One example is a side-pull door device shown in Fig. 8 that drives the left and right door bodies to slide against each other and open and close. The driving device 102 shown in the figure is provided above the left and right door bodies 100A and 100B, and uses a winding drive mechanism. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, it has: a driving pulley 104 and a driven pulley 106, which are arranged separately from each other in the door opening and closing directions, a leather belt 108 across the belt, and a belt 08 The lower part is a door body 100A that is connected to the approach side (right side in the figure) of the driving pulley 104 through the connecting member 1 10A, and the upper part of the belt 108 is connected to the driven pulley 106 through the connecting member 110B. The door body 100B on the near side (the left side in the figure). As a driving source, a reduction motor 120 is used, and an output shaft thereof is connected to the above-mentioned driving pulley 104. The reduction motor 120 includes a motor body 122 and a reduction gear 124, and the input shaft and the output shaft of the reduction gear 124 are arranged in a state parallel to each other (a state facing backward in the figure), and a front end of the input shaft is connected to the Paper size applies Chinese National Standard (CNS) A4 specification (210X29? Mm) -5- 565515 A7 B7 V. Description of the invention (2) The motor body 122 mentioned above is connected to the front end of the output shaft and the original drive pulley 104 is connected . (Please read the precautions on the back before filling in this page.) The connecting member 110A has a belt-side connecting portion 1 1 2 that is fixed to the lower portion of the belt 108 and extends downward from the belt 108. The lower end of the belt-side connecting portion 1 12 is a middle connecting portion 1 1 that extends horizontally in the horizontal direction of the driving pulley 104 (right side of the figure). 3 From this intermediate connecting portion 1 1 3 extends downward and is fixed to the right door. The door-side connection portion 1 1 4 at the upper end of the main body 100A. Similarly, the connecting member 1 1 0B has a belt-side connecting portion 1 1 6 that is fixed to the upper portion of the belt 108 and extends from the upper portion to a lower portion of the lower portion of the leather belt 108. From this belt, The lower end of the side connecting portion 1 1 6 is a middle connecting portion 1 1 7 extending horizontally in the direction of the driving pulley 104 (right side of the figure). The middle connecting portion 1 1 3 extends downward and is fixed to the left door body 100B. The upper end of the door-side connecting portion 1 1 8. The consumer cooperation of the Intellectual Property Bureau of the Ministry of Economic Affairs is printed in this device. As shown in the figure, from the closed state of the two door bodies 100A and 100B, the prime mover 104 is rotated in the counterclockwise direction by the action of the reduction motor 120. When driven, the lower part of the belt 108 and the right door body 100A connected to it slide to the right, and the upper part of the belt 108 and the left door body 100B connected to it slide to the left. That is, the door opens. Conversely, if the original driving pulley 104 is rotated and driven clockwise in the figure from the door open state, the two door bodies 100A and 100B are slidingly driven in the closing direction. [Problems to be Solved by the Present Invention] The aforementioned reduction motor 120 has a large reduction gear 124, and further, because this paper size applies the Chinese National Standard (CNS) A4 specification (210X: 297 mm) 565515 employees of the Intellectual Property Bureau of the Ministry of Economic Affairs消 # Cooperative cooperative printing A7 B7 V. Description of the invention (3) In order to make the motor body 122 protrude toward the front side from the reduction gear 124 and the original driving pulley 104, the arrangement of the reduction motor 120 requires a large space. In order to avoid interference between the reduction motor 120 and the connection member (especially the connection member 110A connected to the right door body 100A near the reduction motor 120), the design is limited, and there is generally a problem that the entire device is enlarged. . For example, in order to reduce the size of the entire device, the distance between the original pulley 104 and the driven pulley 106 can only be reduced, and in order to ensure the sliding travel of the two door bodies 100 A and 100B to a large extent, as shown in the figure, It is preferable that each link member 110A and 110B is extended toward the door opening and closing direction so that each door-side link portion 114 and 118 can be moved to positions outside the reduction motor 120 and the driven pulley 106, respectively. 1 1 0 A's door-side connection 1 1 4 or the intermediate connection 1 1 3 will not interfere with the large reduction motor 120. As shown in the figure, the door-side connection 1 1 4 must pass through the lower of the reduction motor 1 20 The positions of the door-side connecting portion 1 1 4 and the reduction motor 120 are shifted from side to side, and there is a problem that the height of the entire device is increased in this portion. Moreover, the means for avoiding the above-mentioned dryness can be avoided without increasing the size of the device. Although the connection portion 1 1 0A, for example, the intermediate connection portion 1 1 3 and the door-side connection portion 114 can be expanded toward the front side (the front side in the figure). The two connecting portions 113 and 114 are arranged through the front side of the reduction motor 120 to connect the connecting member 110A. However, as described above, the reduction motor 1 2 0 is stepped from the reduction gear 1 2 4 to have the motor body 1 22 toward The front side protrudes from the ground, so in order to avoid the drying of the motor body 122 and the connecting member Π0A, the connecting parts 1 13 and 114 must be expanded to the front side considerably. This part will make the paper size fit the Chinese national standard.

In particular, in the case of a door opening and closing device for a railway vehicle, since a cover or an inspection cover is provided at the front and rear (inside and outside the vehicle), if the depth is large, the inside of the cover or the inspection cover cannot be accommodated. The problem. The present invention has been made in view of the above, and it is an object of the present invention to reduce the overall size of the apparatus while opening and closing the door for a railway vehicle while ensuring the sliding stroke of the door body sufficiently. [Means for Solving the Problems] In order to solve the above-mentioned problems, the railway vehicle door opening and closing device of the present invention is directed to a railway vehicle in which the door bodies provided on the left and right sides of the vehicle are slidably driven in the opening and closing directions by using electric motors as a driving source. The door opening / closing device is characterized by comprising: a prime mover provided on the output side of the electric motor; and a position away from the prime mover toward the opening / closing direction of the door body is provided with a rotation axis parallel to the prime mover.

Description of the invention (5) (Please read the precautions on the back before filling this page) However, the so-called "outer rotor type direct drive motor" here means: The rotor (outer rotor) on the outer side of the direction, and the rotational driving force of the rotor is a motor that directly outputs to the outside without passing through the reducer. This outer rotor type direct drive motor does not have a reducer part, and only a small installation space is required, and because the rotor is arranged outside the radial direction of the stator, the size in the axial direction is also very small. Therefore, by providing a prime mover on the outer rotor, the direct connection of the first connecting member and the outer rotor type direct drive motor can be avoided while the first connecting member and the outer rotor type direct drive motor do not swell, without expanding the front side of the first connecting member. The space on the front side of the drive motor in the axial direction allows the first connecting member to pass through the ground. This allows the height and depth of the device to be restrained while the door opening and closing stroke, which is the movement stroke of the first connecting member, is sufficiently secured. (Dimensions in a direction parallel to the motor shaft direction) are reduced. This is printed here by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. The aforementioned outer rotor of the direct drive motor is located around the stator. Generally, the outer diameter is large, although it may not be consistent with the outer diameter obtained by the original car. However, when there is such a difference in diameter, the outer rotor of the direct drive motor has a rotor body portion disposed around the stator, and the rotor body portion protrudes forward from the center of rotation of the rotor body portion. By forming the structure of the rotation output portion of the original vehicle having a smaller diameter than the rotor portion, the original vehicle having an appropriate outer diameter can be provided on the outer rotor regardless of the diameter of the rotor body portion. The first connecting member is arranged on the front side of the rotor body portion so that the first connecting member passes through the upper side or the lower side of the rotating output unit, so that the rotating output portion faces the rotor body. This paper size applies the Chinese National Standard (CNS) A4 specification (210X 297 mm) -9- 565515 A7 __ B7 V. Description of the invention (6) The axial direction of the part protrudes, and it is not necessary to make the first connecting member face the front side of the ground The expansion can pass through the front side of the outer rotor without interfering with the outer rotor. Thus, the present invention has less design restrictions for the first coupling member and direct drive motor to avoid the interference, and the i-th The degree of freedom in setting the shape of the connecting member is high. Therefore, for example, the first connection member and the second connection member include a driving-side connection portion along the extension of the winding transmission member, and an end portion of the driving-side connection portion on the rear side in the door opening direction is fixed. The structure may be used in the middle of the winding drive member. With this structure, the height of the device can be reduced and the sliding stroke of the door body can be sufficiently ensured. In addition, the first connecting member includes the driving-side connecting portion, an end in a door opening direction front side that connects the driving-side connecting portion, and the door-side connecting portion of the first door body; The opening and closing position of the door body is such that the door-side connecting portion is positioned outside the door driving direction of the direct drive motor at any time, and is arranged such that the drive-side connecting portion may be located on the front side in the axial direction of the direct drive motor. . In this configuration, the door-side connecting portion is positioned outside the direct drive motor at any time, and does not pass through the front side of the direct drive motor. Therefore, it is not necessary to prevent the door from drying up by the direct drive motor and the door-side connecting portion. The side connection portion swells toward the front side, and the depth dimension of the device of the sub-section can be further reduced. However, in this structure, although it is necessary to arrange a drive-side connecting portion on the front side of the direct drive motor, as long as the drive-side connecting portion has a paper size along the roll, the Chinese National Standard (CNS) A4 standard (210 × 297 mm) is applicable. ) (Please read the notes on the back before filling out this page)

On the contrary, by driving the driving pulley 23 clockwise from the door state, the paper size of the two doors is adapted to the Chinese National Standard (CNS) A4 specification (210X297 mm) -17- 565515 Economy Printed by the Consumer Cooperatives of the Ministry of Intellectual Property Bureau A7 __ B7 _ ^ _ V. Description of the Invention (14) 10A and 10B are driven simultaneously in the direction of closing. In this device, because the electric motor 22 is a direct-drive motor of an outer rotor type, the portion of the motor 22 without a reduction gear can be provided with less space (especially the space seen from the front), and because Since the outer rotor 40 is arranged on the outer side of the stator 30 in the radial direction, the dimension in the axial direction is also very small. Therefore, by providing the motive vehicle 23 on the outer rotor 40, the first connecting member 27 and the aforementioned electric motor can be avoided while the front side (left side in FIG. 4) of the first connecting member 27 is not greatly expanded. The dryness of the motor 22 is arranged so that the first connecting member 27 passes through the space in the front side in the axial direction of the motor 22, so that the door opening and closing stroke, which is the movement stroke of the first connecting member 27, can be sufficiently secured while the Both the height dimension of the device and the backward dimension (the dimension in the left-right direction in FIGS. 2 to 4) are less suppressed. More specifically, in this embodiment, although the overall diameter of the outer rotor 40 is larger than the diameter obtained on the motive pulley 23, the outer rotor 40 is formed from a rotor disposed around the stator The body portion 42 has a structure in which the rotation output portion 44 constituting the driving pulley 23 protrudes toward the front side in the axial direction, and the driving pulley 23 and the outer rotor 40 having an appropriate diameter can be integrated. In addition, when the first connection member 27 is passed through the lower side of the rotation output portion 44 on the front side of the rotor body portion 42 (in the case where the first connection member 27 is connected to the upper portion of the skin 26), The first connecting member 27 may be disposed above the rotary output portion 44. Although the rotary output portion 44 is protruded from the rotor body portion 42 toward the front side in the axial direction, the front side of the first connecting member 27 may not be required. The earth swells and does not communicate with the aforementioned outer rotor 40 thousand times.

(Please read the precautions on the back before filling out this page.) For each linking member 27, 28, the two linking members 27, 28 are made to have a drive-side linking portion of the drive member extending along the leather 26. 27a, 28a, the shape of the door-side connecting portions 27b, 28b provided at the front leg portions in the door opening direction, and the ends of the driving-side connecting portions 27a, 28a in the door opening direction rear side are fixed to the midway portion of the belt 26 Therefore, as shown in FIG. 8, in order to avoid the dryness of the intermediate connection portion 1 1 3 and the reduction motor 120 of the connection member 1 10 A, the conventional device can be disposed side-by-side as compared with the conventional device. The height of the device is small, and the sliding stroke of the door body is sufficiently ensured. Further, in this embodiment, the door-side connecting portion 27b of the first connecting member 27 is disposed at an outer position (right side in the first figure) in the door opening and closing direction of the electric motor 22 at any time, and because the side connecting portion 2M Since it does not pass through the front side of the electric motor 22, it is not necessary to expand the door-side connection portion 27b toward the front side in order to prevent the two from drying out, and the depth dimension of some devices can be further reduced. Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. For example, the second embodiment is shown in FIGS. 6 and 7. In comparison with a device that is arranged on the inner side (left side in FIG. 6) of the electric motor 22 in the door opening and closing direction, in this device, as shown in FIG. The upper half of the door-side connecting portion 27b swells outward (right side in FIG. 7). Although part of the door-side connecting portion 27b is likely to dry out with other parts, as in the first embodiment, the door-side connecting portion 27b has nothing to do with the door body.

The paper size is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) -19- 565515 A7 B7 Printed by the Consumers ’Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs In the case of the (16) side, it is not necessary to expand the door-side connecting portion 27b (refer to FIG. 4), and the depth of the sub-device is reduced. However, with the arrangement as in the first embodiment, although the drive-side connection portion 27a of the first connection member 27 is positioned at the front side in the axial direction of the electric motor 22 at any time, the drive-side connection portion 27a has The shape of the flap 26 may be sufficient. Since the height is required to be smaller than that of the door-side connecting portion 27b, even if the driving-side connecting portion 27a is arranged on the front side of the direct drive motor, it will hardly affect the entire device. the size of. Moreover, in the first embodiment, the door-side connecting portion 28 of the second connecting member 28 is also located outside the driven pulley 24 at any time because of the position of the door body 10B (the left side in the first figure). Therefore, as in the aforementioned second embodiment, the door-side connecting portion 28b of the second connecting member 28 is located inside the driven pulley 24 (right side in FIG. 6), and there is no need to avoid the driven belt. The front side of the door-side connecting portion 28b is inflated by the dryness of the wheels 24 or the first connecting member 27 (see the door-side connecting portion 28b in FIG. 2 and the door-side connecting portion 28b in FIG. 7). Reduction of device depth size. Furthermore, in the first embodiment, the controller 54 for controlling the driving of the electric motor 22 is disposed between the two pulleys 23 and 24.
