[0039] Please refer to Figures 1 to 9 .

[0040] This specific embodiment discloses a side-sliding door device, including a door leaf 1, a guide assembly 2 and a power assembly 3, wherein the door leaf 1 is installed on the inner side of a vehicle body; the guide assembly 2 is installed on the vehicle body, and the extension direction of the guide assembly 2 has components of a first direction and a second direction at the same time, the first direction is the length direction of the vehicle body, and the second direction is the width direction of the vehicle body; the power assembly 3 is installed on the vehicle body, and is used to push the door leaf 1 to move along the guide assembly 2 between a first position and a second position; when the door leaf 1 is in the first position, the door leaf 1 is in an open state; when the door leaf 1 is in the second position, the outer side surface of the door leaf 1 is flush with the outer side surface of the vehicle body and is in a closed state.

[0041] It should be noted that, in the process of the door leaf 1 moving along the guide assembly 2 in this specific embodiment, it will move along the extension direction of the guide assembly 2, and when moving along the second direction, the door leaf 1 can be opened or closed.

[0042] The guide component 2 can be a guide slot or a guide rail, which is determined according to actual conditions and will not be described in detail here.

[0043] In the process of the side sliding door device provided in this specific embodiment, when the door leaf 1 needs to be closed, the power assembly 3 needs to drive the door leaf 1 to move along the guide assembly 2. Since the guide assembly 2 has components in both the first direction and the second direction, the first direction is the length direction of the vehicle body, and the second direction is the width direction of the vehicle body, when the door leaf 1 moves along the guide assembly 2, the door leaf 1 will move outward along the width direction of the vehicle body while closing the door, until the outer side of the door leaf 1 is flush with the outer side of the vehicle body, which can effectively reduce aerodynamic noise and aerodynamic resistance. In addition, the door leaf 1 is located on the inner side of the vehicle body, which can effectively reduce the risk of the door leaf 1 falling off and flying out.

[0044] Based on the above embodiment, the guide assembly 2 includes a guide rail, which protects a translation section 21 arranged along the length direction of the vehicle body and an inclined clamping section 22, wherein the clamping section 22 has components in both the first direction and the second direction.

[0045] like Figure 2 As shown, when the door leaf 1 is in the position shown by A1, the door leaf 1 is in the first position and is in an open state, and when the door leaf 1 is in the position shown by A2, the door leaf 1 is in the second position and is in a completely sealed closed state.

[0046] The extension direction of the guide rail is as follows Figure 3 As shown, the door leaf 1 includes a translation section 21 and a pressing section 22. The connection between the translation section 21 and the pressing section 22 is a smoothly transitioned curved section 23. When the door leaf 1 moves along the guide rail, the door leaf 1 moves along the translation section 21. Figure 2 In the direction shown, the door leaf 1 gradually moves to the left. In the process of the door leaf 1 moving along the pressing section 22, the door leaf 1 Figure 2 Move upward in the direction shown to press against the door frame 4 to achieve a sealed closure.

[0047] In this specific embodiment, the pressing section 22 and the translation section 21 are connected by a smoothly transitioning curved section 23, so that the door leaf 1 can move smoothly during closing or opening, which can effectively improve the smoothness.

[0048] In a specific embodiment, in combination Figure 5 , Figure 7 , Fig. 9 As shown, the side sliding door device also includes a door frame 4 arranged on the vehicle body, a step 41 is arranged on one side of the door frame 4 facing the inner side of the vehicle body, and the door leaf 1 is provided with a recess 11 for cooperating with the step 41 to prevent the door leaf 1 from being separated. The step 41 is arranged so that the door leaf 1 can be pressed on the step 41 when it is in a fully closed state, and the size of the door leaf 1 is larger than the size of the opening of the door frame 4, which can effectively prevent the door leaf 1 from being separated to the outside.

[0049] Specifically, a first sealing member 5 may be disposed in the recess 11 on the front side facing the step 41 , and a second sealing member 6 may be disposed on the side of the recess 11 for contacting the side surface of the step 41 .

[0050] The first seal 5 and the second seal 6 may be as follows Figure 5 , Figure 7 , Fig. 9 In the sealing structure shown, the surface of the first sealing member 5 is provided with protruding claws, which can effectively improve the sealing effect.

[0051] The power assembly 3 further includes a pressing member 31, which has a push end that is movable and / or rotatable, and the push end is used to push the door leaf 1 to move to a second position in a direction of pressing the door frame 4, so that the recess 11 abuts against the step 41 and seals. Figure 4 , Figure 6 , Figure 8 As shown, the tightening member 31 includes a tightening cylinder, and the pushing end is a pushing rod 311 driven to rotate by the tightening cylinder.

[0052] The power assembly 3 also includes a push member, which can push the door leaf 1 to move between a first position and a third position. The third position is between the first position and the second position. When the door leaf 1 is in the second position, the recess 11 of the door leaf 1 contacts the step 41 of the door frame 4, but the outer side surface of the door leaf 1 is recessed inward relative to the outer side surface of the vehicle body.

[0053] In the specific use process, when the door leaf 1 needs to be adjusted from the open state to the fully closed state, first, the pusher pushes the door leaf 1 from the first position to the third position. When the door leaf 1 is in the first position, Figure 8 , Fig. 9 As shown, there is a large gap between the door leaf 1 and the door frame 4. When the door leaf 1 is in the third position, as shown in FIG. Figure 6 , Figure 7 As shown, the door leaf 1 and the door frame 4 are already in a fully closed state, but sealing cannot be achieved; at this time, the control cylinder drives the push rod 311 to rotate, press the door leaf 1, and move the door leaf 1 along the pressing section 22 of the guide rail until the first seal 5 and the second seal 6 are squeezed, and the outer side of the door leaf 1 is flush with the outer side of the vehicle body, as shown in FIG. Figure 4 , Figure 5 As shown, a completely sealed closure is achieved.

[0054] Furthermore, it can also include a controller and a position sensor for detecting the position of the door leaf 1 and a solenoid valve assembly 7. The position sensor and the power assembly 3 are all connected to the controller. The controller is used to control the action of the power assembly 3. When the controller controls the power assembly 3 to drive the door leaf 1 to close, but the position sensor detects that the door leaf 1 is not fully closed, a warning message will be issued, and the rail vehicle will be prohibited from running when the door leaf 1 is not completely sealed and closed; when the controller controls the power assembly 3 to drive the door leaf 1 to open, but it is not fully opened, a warning message will be issued to enable the staff to obtain information in time and perform maintenance. The solenoid valve assembly 7 can be used to control the power on or off of the power assembly 3.
