Detailed Implementation

[0019] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] This application provides a low-entry cab, which includes a vehicle body and an outward-swinging door 10 connected to the vehicle body to open and close the door's entrance / exit.

[0021] Figure 1 A schematic diagram of the structure of the outward-swinging door 10 in one or more embodiments of this application is shown. Figure 2 It shows Figure 1 A structural diagram from another perspective. Combined with... Figure 1 The outward-swinging door 10 includes a door body 100, a hinge 200, a rotating link 300, and a lifting device 400. The hinge 200 is located on the vertical side of the door body 100, and the door body 100 is connected to the hinge 200. The lifting device 400 is mounted on the door body 100 and is connected to a drive rod 410. At least one end of the rotating link 300 is connected to the drive rod 410, and the other end is connected to the back of the door body 100. When the lifting device 400 is activated, the door body 100 is lowered and swayed outward through at least one link to open the door. When the door needs to be closed, the lifting device 400 is activated again, and the door body 100 is raised and retracted through at least one link.

[0022] In the relevant technology, the door body 100 is provided with an observation window 140. The glass 500 inside the observation window 140 is a fixed structure. On the one hand, the passenger side and the driver side cannot open the window for ventilation, which affects comfort. On the other hand, if the temperature difference between the inside and outside of the vehicle environment is large, water vapor is easy to form on the inside of the glass 500. The water vapor obstructs the view and affects driving safety.

[0023] Figure 3 It shows Figure 1 A schematic diagram of the explosion. Combined with... Figure 3Based on the aforementioned technical problems, the outward-swinging door 10 provided in this application includes, in addition to the door body 100 and the glass 500, a lifter 600. The lifter 600 is disposed inside the door body 100, and the glass 500 can be raised and lowered via the lifter 600 to open or close the observation window 140 on the door body 100. When it is necessary to raise or lower the glass 500, the lifter 600 is controlled to descend, thereby opening the window for ventilation and improving passenger comfort. Additionally, when fog forms on the inside of the glass 500, the observation window 140 can be opened to assist in removing the fog and improve driving safety. The specific details of the outward-swinging door 10 will now be further described with reference to the accompanying drawings.

[0024] Combination Figure 3 The door 100 provided in this application includes a frame 110, a first trim panel 120, and a second trim panel 130. The frame 110 serves as the carrier of the door 100. An observation window 140 is provided in the upper middle part of the frame 110 to ensure that the observation window 140 has a suitable height for the driver to observe the external vehicle conditions. The first trim panel 120 is installed on the upper inner side of the frame 110 and surrounds the observation window 140. The second trim panel 130 is installed on the lower inner side of the frame 110 and is located below the observation window 140. The first trim panel 120 and the second trim panel 130 are integrally formed structures. The arrangement of the first trim panel 120 and the second trim panel 130 can cover the exposed sheet metal of the frame 110, improving the passenger experience and subjective feeling.

[0025] Figure 4 It shows Figure 3 A schematic diagram of the skeleton 110 in the diagram, combined with Figure 4 In some embodiments, the frame 110 is provided with an assembly channel 150, the top of which extends to the top of the observation window 140, and the bottom of which extends towards the bottom of the frame 110. A glass 500 is slidably disposed within the assembly channel 150. When the observation window 140 is closed, the top of the glass 500 moves to the top of the assembly channel 150, and the bottom of the glass 500 is below the observation window 140 to seal it. When the observation window 140 needs to be opened, the glass 500 moves downwards, causing at least a portion of the glass 500 to move below the observation window 140, thereby opening at least a portion of the observation window 140 for ventilation and improved passenger comfort. Additionally, fogging can be generated on the inside of the glass 500 to assist in removing water vapor and improve driving safety.

[0026] Figure 5 It shows Figure 4 A magnified diagram of point A in the image. (Combined with...) Figure 5In some embodiments, the outward-swinging door 10 further includes at least one of an outer water cutter 710 and an inner water cutter 720. Both the outer water cutter 710 and the inner water cutter 720 are connected to the frame 110. The outer water cutter 710 is located on the outer side of the bottom of the observation window 140 in the thickness direction, and the inner water cutter 720 is located on the inner side of the bottom of the observation window 140 in the thickness direction. Both are located on both sides of the glass 500. During the raising and lowering of the glass 500, at least one of the outer water cutter 710 and the inner water cutter 720 can be used to remove water vapor from the glass 500, making it easier for the driver to observe the rearview mirror, while ensuring the sealing of the entire door assembly. For example, the outward-swinging door 10 includes an outer water cutter 710 and an inner water cutter 720, both of which are made of rubber and are embedded on the outer and inner sides of the bottom of the observation window 140. In some other embodiments, only one of the outer water cutter 710 and the inner water cutter 720 may be present, and this application does not limit this.

[0027] Combination Figure 3 In some embodiments, the lift 600 is connected to the inside of the frame 110 and located below the observation window 140, and is covered by the second trim panel 130 to shield the lift 600, thereby improving the passenger experience and subjective feeling.

[0028] Figure 6 A schematic diagram of the elevator 600 in its first state is shown. Figure 7 A schematic diagram of the elevator 600 in its second state is shown. Figure 8 A schematic diagram of the component assembly at mounting base 660 is shown. Figure 9 It shows Figure 8 A schematic diagram of the explosion. Combined with... Figures 6-9 In some embodiments, the lifter 600 includes a drive member 610, a winding wheel 620, a support member 630, a guide wheel 640, and a directional wheel 650. The drive member 610 is connected to the door body 100 and has a rotatable output portion. The winding wheel 620 is connected to the output portion of the drive member 610 to rotate synchronously with the output portion of the drive member 610. The support member 630 is disposed inside the door body 100, and the bottom of the glass 500 is supported by the support member 630. The guide wheel 640 is disposed above the winding wheel 620 and rotatably connected to the door body 100. The directional wheel 650 is disposed below the winding wheel 620 and connected to the door body 100. One end of the flexible member is fixedly connected to the directional wheel 650, and the other end of the flexible member is wound around the winding wheel 620, passes around the guide wheel 640, and is connected to the support member 630. Figure 6As shown, when it is necessary to control the glass 500 to lower to open the observation window 140, the drive unit 610 is controlled to operate. For example, the output of the drive unit 610 rotates in the forward direction, and the drive unit 610 drives the winding wheel 620 to rotate synchronously in the forward direction. The flexible member releases the wire onto the winding wheel 620. Under the weight of the glass 500 and the support member 630, the support member 630 moves down, and correspondingly the glass 500 moves down, so that at least a portion of the glass 500 is located below the observation window 140, thereby opening at least a portion of the observation window 140; Figure 7 As shown, if it is necessary to control the glass 500 to rise in order to close the observation window 140, the drive unit 610 is controlled to operate. For example, the output part of the drive unit 610 rotates in the opposite direction, and the drive unit 610 drives the winding wheel 620 to rotate in the opposite direction synchronously. The flexible part is wound on the winding wheel 620. Under the action of the flexible part, the support member 630 moves upward, which in turn drives the glass 500 to move upward, thereby closing the observation window 140.

[0029] Combination Figures 6-9 In specific implementation, the lifting device 600 also includes a mounting base 660, which is fixedly connected to the inner side of the frame 110 by bolts and other components. The driving component 610 can be a motor, which is connected to the outer side of the mounting base 660. The output shaft of the motor passes through the mounting base 660, and the winding wheel 620 is rotatably disposed in the mounting base 660 and connected to the output shaft of the motor. The output shaft of the motor is configured as the output part of the driving component 610. The output shaft of the motor and the winding wheel 620 can be a worm gear transmission method to reduce the thickness dimension of the door body 100. In addition, the mounting base 660 has a through-hole 670 along the vertical direction for the flexible component to pass through. The flexible component can be a steel wire rope, which has both flexibility and high strength. Furthermore, the mounting base 660 has a split structure to facilitate the assembly of the winding wheel 620 within the mounting base 660.

The bottom of the glass 500 is accommodated in the two support grooves 633. The second side of the connecting frame 631 has a through second locking groove 634. The other end of the flexible member passes through the second locking groove 634. The other end of the flexible member may be provided with a second protrusion so that the other end of the flexible member can be fixed to the bottom of the second locking groove 634. For example, a protrusion is provided on the second side of the connecting bracket 631, and a second locking groove 634 is formed on the protrusion. The second locking groove 634 is arranged vertically through the protrusion, and may also have a certain tilt angle. This application does not limit this.
