DETAILED DESCRIPTION

[0045] One object of the present invention is to provide a vehicle 100, which can be a welfare vehicle, a welfare vehicle or other vehicles suitable for transportation 100. The vehicle 100 is suitable for carrying wheelchairs and wheelchair users, and is also suitable for carrying wheelchair beds, transport carts, etc.

[0046] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0047] Combination Figures 1 to 17 According to an embodiment of the present invention, a vehicle 100 includes a vehicle body 10 and a tray 20. The vehicle body 10 has an entrance 101. The tray 20 is connected to the vehicle body 10, and the tray 20 is suitable for connecting with the entrance 101 to form a passage for entering and exiting the vehicle body 10. When the tray 20 is connected with the entrance 101, a wheelchair or other equipment can enter the vehicle body 10 through the tray 20, and can also be sent out from the vehicle body 10 through the tray 20. The entrance 101 can be set at the rear of the vehicle body 10, and the wheelchair can enter and exit from the rear of the vehicle body 10; in addition, the entrance 101 can also be set on the side of the vehicle body 10, and the wheelchair can enter and exit from the side of the vehicle body 10; the entrance 101 can also be set at other positions of the vehicle body 10 as needed. In addition, the present invention is mainly described by taking a wheelchair as an example, but this is not a limitation to the scope of protection of the present invention. In the present invention, by setting the tray 20, it can also be used for driving in and out of other devices (such as transport trolleys, wheelchair beds, etc.).

[0048] In addition, when a wheelchair or the like passes through the tray 20 to enter and exit the vehicle body 10, deviation may occur, especially for a wheelchair with motor-driven wheels, which is more likely to occur. In order to facilitate the use of the tray 20, as shown in FIG. Figure 1-Figure 17 In the present invention, a transition guide rail 13 is provided, which is rotatably connected to the vehicle body 10, and the transition guide rail 13 is adapted to extend from the entrance 101 and cooperate with the tray 20 to guide between the tray 20 and the vehicle body 10. When a wheelchair or the like enters the vehicle body 10 from the tray 20, or moves from the vehicle body 10 to the tray 20, the transition guide rail 13 can provide guidance for the wheelchair or the like to prevent the wheelchair or the like from deviating from a predetermined direction during movement.

[0049] Alternatively, if Figures 11 to 17The present invention further includes an orientation mechanism, which is connected to the vehicle body 10 and the transition guide rail 13, respectively, and is configured to limit the rotation direction of the transition guide rail 13 relative to the vehicle body 10. Through the limitation of the orientation mechanism, the transition guide rail 13 can be guided to rotate in a predetermined direction, thereby ensuring the stable cooperation between the transition guide rail 13 and the tray 20, improving the stability of the wheelchair during the movement from the tray 20 to the vehicle body 10 or from the vehicle body 10 to the tray 20, and optimizing the guiding effect of the transition guide rail 13.

[0050] The orientation mechanism in the present invention has various forms, such as connecting a hinge 16 (such as Fig.11 , Fig.14 as well as Fig.15 ), the transition guide rail 13 is directionally rotated relative to the vehicle body 10 through the rotating axis of the hinge 16, and the present invention also provides other various directional mechanisms, wherein these directional mechanisms can be combined or independently set, and can all achieve the directional rotation of guiding the transition guide rail 13.

[0051] like Fig.11 In some embodiments of the present invention, the directional mechanism includes a support rod 14, the support rod 14 includes a pressure tube and a piston rod, the piston rod is telescopically connected to the pressure tube, the pressure tube is rotatably connected to the vehicle body 10, and the piston rod is rotatably connected to the transition guide rail 13. The piston rod in the support rod 14 is directional and telescopic relative to the pressure tube, and the connection between the support rod 14, the vehicle body 10 and the transition guide rail 13 forms a triangular stable structure, and the directional rotation of the transition guide rail 13 relative to the vehicle body 10 is achieved by the telescopic support rod 14, and the triangular stable structure constructed by the support rod 14 can improve the stability and connection strength of the transition guide rail 13.

[0052] The pressure tube of the present invention is filled with a buffer medium, for example, a buffer structure such as gas, liquid, or a gas-liquid mixed medium is filled in the pressure tube, which can improve the stability of the transition guide 13 during rotation and effectively control the rotation speed of the transition guide 13. The rotatable connection between the support rod 14 and the vehicle body 10 and the transition guide 13 can avoid jamming and improve stability. Optionally, a pump body structure can be combined with the support rod 14 to form a driving structure for driving the transition guide 13 to rotate.

[0053] In addition, the support rod 14 of the present invention is rotatably connected to at least one of the vehicle body 10 and the transition guide rail 13 around a fixed axis, thereby further optimizing the limiting effect on the rotation direction of the transition guide rail 13.

[0054] like Figures 11 to 13 In some embodiments of the present invention, the orientation mechanism further includes a rotating shaft 151 .

[0055] Optionally, a rotating shaft 151 is connected between the pressure pipe and the vehicle body 10, and the rotating shaft 151 is rotatably connected to one of the pressure pipe and the vehicle body 10 around its axis. That is, the pressure pipe is rotatable relative to the vehicle body 10 around the axis of the rotating shaft 151; or the rotating shaft 151 is rotatable relative to the vehicle body 10 around the axis of the rotating shaft 151; or the pressure pipe is rotatable relative to the vehicle body 10 around the axis of the rotating shaft 151, and the rotating shaft 151 is rotatable relative to the vehicle body 10 around the axis of the rotating shaft 151. In this way, the pressure pipe can rotate relative to the vehicle body 10 around a fixed axis, thereby improving the guiding effect of the directional rotation of the transition guide rail 13. In addition, when the pressure tube is connected to the car body 10 via the rotating shaft 151, the piston rod and the transition guide rail 13 can be connected by the rotating shaft 151, and other articulation forms (such as universal hinges) can be used between the piston rod and the transition guide rail 13. It is only necessary for the support rod 14 to rotate with one of the car body 10 and the transition guide rail 13 around a fixed rotation axis, and the connection between the support rod 14 and the other of the car body 10 and the transition guide rail 13 does not affect the rotation, thereby effectively limiting the rotation direction of the transition guide rail 13.

[0056] In addition, a rotating shaft 151 may be provided between the piston rod and the transition guide 13, and the rotating shaft 151 is rotatably connected to one of the piston rod and the transition guide 13 around its axis. That is, the piston rod is rotatable around the axis of the rotating shaft 151 relative to the transition guide 13; or the rotating shaft 151 is rotatable around the axis of the rotating shaft 151 relative to the transition guide 13; or the piston rod is rotatable around the axis of the rotating shaft 151 relative to the transition guide 13, and the rotating shaft 151 is rotatable around the axis of the rotating shaft 151 relative to the transition guide 13. Thus, the piston rod can rotate around the axis relative to the transition guide 13, and the guiding effect of the directional rotation of the transition guide 13 is improved. In addition, when the piston rod is connected to the transition guide 13 through the rotating shaft 151, the pressure pipe and the vehicle body 10 can be connected by the rotating shaft 151, and other hinge forms can be used between the pressure pipe and the transition guide 13.

[0057] As mentioned above, the pressure tube in the present invention can be filled with pressure media such as gas, liquid or gas-liquid mixture. In other words, the support rod 14 in the present invention can be a gas spring, a hydraulic rod or a pneumatic rod.

[0058] The orientation mechanism may further include a first bracket 152, the first bracket 152 is fixedly connected to the vehicle body 10, and a rotating shaft 151 is provided at the end of the first bracket 152. The vehicle body 10 of the present invention may include a carriage 11 and a carriage guide rail 12, wherein the first bracket 152 may be installed on the carriage guide rail 12, and optionally, the first bracket 152 is connected to the upper surface of the carriage guide rail 12.

[0059] In addition, the orientation mechanism may further include a second bracket 153, which is connected to the transition rail 13, and a rotating shaft 151 is provided at the end of the second bracket 153. When the tray rail 21 is laid flat, the second bracket 153 is connected to the upper surface of the tray rail 21.

[0060] like Figures 15 to 17 In some embodiments of the present invention, the orientation mechanism of the present invention may include a guide plate 17, the guide plate 17 is fixedly connected to one of the car body 10 and the transition guide rail 13, and the other of the car body 10 and the transition guide rail 13 is provided with a guide groove 106, and the guide plate 17 can be movably inserted in the guide groove 106. That is, the guide plate 17 is fixedly connected to the car body 10, and the transition guide rail 13 is provided with a guide groove 106, and the transition guide rail 13 can rotate along the guide plate 17; or, the guide plate 17 is fixedly connected to the transition guide rail 13, and the car body 10 is provided with a guide groove 106, and the guide plate 17 is rotatably connected to the car body 10. When the guide plate 17 is inserted into the guide groove 106 and slides along the guide groove 106, since the guide plate 17 is fixedly connected to one of the car body 10 and the transition guide rail 13, the transition guide rail 13 will rotate along the extension direction of the guide plate 17, thereby limiting the rotation direction of the transition guide rail 13.

[0061] The guide plate 17 in the present invention can be set in the form of a linear guide rail, an arc guide rail, a folded line guide rail, etc., all of which can limit the rotation direction of the transition guide rail 13. In a specific embodiment of the present invention, the guide plate 17 is constructed in the shape of an arc plate, and the central axis of the guide plate 17 coincides with the rotation central axis of the transition guide rail 13; or the central axis of the guide plate 17 is parallel to and close to the rotation central axis of the transition guide rail 13. In this way, the guide plate 17 can be slidably inserted into the guide groove 106, and the guide plate 17 can slide stably relative to the guide groove 106. In addition, the size of the guide groove 106 can be reduced, reducing the influence of the setting of the guide groove 106 on the structural strength of the transition guide rail 13.

[0062] Optionally, a limiting portion 171 may be provided on the guide plate 17, and the limiting portion 171 is configured to limit the transition guide rail 13 when the transition guide rail 13 rotates to a predetermined position. In other words, when the transition guide rail 13 rotates to a predetermined position along one direction (for example, the direction of rotation from the guide position to the storage position or the direction of rotation from the storage position to the guide position in the present invention), the limiting portion 171 stops against the other of the vehicle body 10 and the transition guide rail 13 or approaches the other of the vehicle body 10 and the transition guide rail 13 to limit the transition guide rail 13 from further rotating in this direction at a larger angle. The limiting portion 171 limits the transition guide rail 13, which facilitates the stable control of the transition guide rail 13.

[0063] Specifically, the transition guide rail 13 may have a guide position and a storage position, and the guide plate 17 is configured to guide the transition guide rail 13 from the guide position to the storage position. A limit portion 171 is provided to limit the transition guide rail 13 at the storage position; or, a limit portion 171 may be provided to limit the transition guide rail 13 at the guide position.

[0064] Optionally, the guide plate 17 can be fixedly connected to the vehicle body 10, and the guide groove 106 is provided on the transition guide rail 13, so that when the transition guide rail 13 rotates in one direction, the distance between the transition guide rail 13 and the limiting portion 171 gradually decreases, and when the transition guide rail 13 rotates to a predetermined position in this direction, the limiting portion 171 will limit the transition guide rail 13 from continuing to rotate in this direction.

[0065] In addition, the guide plate 17 can be fixedly connected to the transition guide rail 13, and the guide groove 106 is provided on the vehicle body 10, so that when the transition guide rail 13 rotates in one direction, the distance between the limiting portion 171 and the vehicle body 10 gradually decreases, and when the transition guide rail 13 rotates to a predetermined position in this direction, the limiting portion 171 will limit the transition guide rail 13 from continuing to rotate in this direction.

[0066] The limiting portion 171 includes a limiting column provided on the guide plate 17, the limiting column protrudes from the surface of the guide plate 17 and is suitable for limiting the transition guide rail 13. For example, the guide plate 17 can be configured in a semicircular arc shape with an opening downward, and a limiting column can be provided at a middle position or an end position of the guide plate 17, and the limiting column can extend from a side surface, an outer peripheral surface, or an inner peripheral surface of the guide plate 17.

[0067] In addition, in the aforementioned embodiment, since the length of the piston rod in the support rod 14 when it is fully retracted or fully extended is fixed, the support rod 14 can realize the positioning of the transition guide rail 13 after the transition guide rail 13 rotates to a predetermined position relative to the vehicle body 10, so as to facilitate the positioning of the transition guide rail 13. In addition, the guide plate 17 can also be combined with the support rod 14 to improve the guiding and limiting effect of the transition guide rail 13. In this case, the limiting portion 171 may or may not be provided on the guide plate 17.

[0068] like Figures 1 to 10 In some embodiments of the present invention, the vehicle body 10 includes: a carriage 11 and a carriage guide rail 12, the carriage 11 is configured with an entrance 101; the carriage guide rail 12 is arranged on the floor of the carriage 11, and the carriage guide rail 12 is configured to guide in the carriage 11. That is, when a wheelchair or the like is located inside the carriage 11, the movement of the wheelchair or the like can be guided by the carriage guide rail 12.

[0069] Optionally, the transition rail 13 is rotatably connected to the carriage rail 12 in the up-down direction. The transition rail 13 is relatively short in length, convenient to control, and easier to be stored in the vehicle body 10.

[0070] In addition, the aforementioned orientation mechanism of the present invention can be connected to the carriage guide rail 12 and the transition guide rail 13 respectively, and the orientation mechanism is configured to limit the rotation direction of the transition guide rail 13 relative to the carriage guide rail 12. Through the guiding structure of the orientation mechanism, it is convenient to rotate the transition guide rail 13 relative to the carriage guide rail 12 in a predetermined direction, improve the matching effect between the transition guide rail 13 and the carriage guide rail 12, and when the transition guide rail 13 cooperates with the carriage guide rail 12 to achieve guidance from the tray 20 to the vehicle body 10, the guiding effect on the wheelchair is improved, which facilitates the travel of the wheelchair.

[0071] In combination with the aforementioned embodiment, the orientation mechanism may include a support rod 14 , which is respectively connected to the transition rail 13 and the carriage rail 12 , for example, the pressure pipe is rotatably connected to the carriage rail 12 , and the piston rod is rotatably connected to the transition rail 13 .

[0072] In combination with the aforementioned another embodiment, the orientation mechanism may include a guide plate 17, the guide plate 17 is fixedly connected to one of the carriage guide rail 12 and the transition guide rail 13, and the other of the carriage guide rail 12 and the transition guide rail 13 is provided with a guide groove 106, and the guide plate 17 can be movably inserted into the guide groove 106. Further, the guide plate 17 is provided with a limiting portion 171, and the limiting portion 171 is configured to limit the transition guide rail 13 when the transition guide rail 13 rotates to a predetermined position.

[0073] When the transition guide rail 13 is connected to the carriage guide rail 12 , the orientation mechanism may also be connected to the carriage 11 and the transition guide rail 13 respectively, so as to guide the rotation direction of the transition guide rail 13 .

[0074] Optionally, in other embodiments of the present invention, the carriage guide rail 12 and the transition guide rail 13 may be connected as one. In other words, the carriage guide rail 12 may not be provided in the carriage 11 of the present invention, and the transition guide rail 13 may be used to guide the movement of the wheelchair in the carriage 11. In this case, the transition guide rail 13 can guide the wheelchair to enter and exit the vehicle body 10, and can also guide the wheelchair to move in the vehicle body 10, thereby simplifying the structure and improving the stability of the guidance of the vehicle 100.

[0075] The carriage rails 12 in the present invention may include two relatively arranged ones, and the guidance and orientation of the wheelchair can be realized by the cooperation of the two carriage rails 12. Among them, the two carriage rails 12 can be respectively constructed as rail structures, that is, the two carriage rails 12 can respectively limit and guide the casters of the wheelchair to realize the guidance of the wheelchair's driving direction; in addition, a guide channel can be constructed between the two carriage rails 12, that is, the wheelchair can travel between the two carriage rails 12. Among them, the two carriage rails 12 can limit the deviation of the wheelchair from its preset direction. Thereby, stable guidance of the wheelchair can be achieved, and the stability of the wheelchair's driving can be improved.

[0076] Optionally, the carriage guide rail 12 in the present invention can be configured in the form of a groove, a convex strip, a plate or a cross beam. When the carriage guide rail 12 is configured in the form of a groove, the caster of the wheelchair can be rotatably embedded in the carriage guide rail 12 to guide the wheelchair; when the carriage guide rail 12 is configured in the form of a convex strip, it can be adapted to a wheelchair with an annular groove on the caster, and by embedding the convex strip-shaped carriage guide rail 12 into the annular groove of the corresponding caster, the multiple casters of the wheelchair can be moved along the corresponding carriage guide rail 12 respectively, thereby guiding the caster to travel; in addition, when the carriage guide rail 12 is configured in the form of a convex strip, a plate, a cross beam, etc., a guide channel can be defined between two carriage guide rails 12, so as to facilitate the movement of the wheelchair along the guide channel and guide the wheelchair, wherein the two carriage guide rails 12 can be located at different height positions on the side of the wheelchair, such as at least one of the inner bottom surface of the carriage 11, the lower part of the carriage 11, the middle part, etc.

[0077] In addition, it should be noted that the distance between the two carriage guide rails 12 in the present invention can be set in a fixed form. For example, the carriage guide rails 12 in the present invention can be set in a fixed connection with the carriage 11. For example, both carriage guide rails 12 can be fixed in the carriage 11, or the two carriage guide rails 12 can be constructed into an integral structure, which can be fixedly connected to the carriage 11 or movably connected.

[0078] In other embodiments of the present invention, in order to adapt to different wheelchairs, the two carriage rails 12 can also be set in the present invention to have an adjustable spacing, so that the spacing between the two carriage rails 12 can be adjusted according to the caster spacing of different wheelchairs, so that the vehicle 100 in the present application can be adapted to different wheelchairs, improving the performance of the vehicle 100. Among them, both carriage rails 12 can be set in a movable form, or one of the two carriage rails 12 can be fixed and the other movable, etc. In other words, the spacing between the two carriage rails 12 in the present invention is adjustable or fixed.

[0079] In some embodiments of the present invention, the vehicle 100 further includes a tray rail 21, which is disposed on the tray 20 and is configured to guide on the tray 20. The tray rail 21 can be used to provide guidance for a wheelchair or the like on the tray 20; or the tray rail 21 is used to guide a wheelchair or the like in and out of the tray 20, thereby achieving stability in the movement of the wheelchair on the tray 20 and in and out of the tray 20.

[0080] In addition, the transition rail 13 is suitable for docking with the tray rail 21. In combination with the above-mentioned embodiment, the transition rail 13 can be docked with the tray rail 21, the carriage rail 12, etc., so that a stable guide structure from the tray 20 to the vehicle body 10 is constructed to improve the guiding effect for the wheelchair, etc.

[0081] Optionally, in some embodiments of the present invention, the transition guide rail 13 is rotatably connected to the vehicle body 10 between a storage position and a guide position in the up-down direction, the transition guide rail 13 is stored in the vehicle body 10 at the storage position, and the transition guide rail 13 extends out of the entrance 101 at the guide position, so as to facilitate the use of the vehicle 100 and improve the guiding effect on the wheelchair and the like.

[0082] As mentioned above, the tray 20 in the present invention can be set as a ramp structure, that is, the tray 20 is rotatably connected to the vehicle body 10. When the tray 20 is rotated to one end connected to the entrance and exit 101 and the other end is lowered to the ground, a wheelchair or the like can move along the tray 20 and can be moved into the vehicle body 10.

[0083] In addition, the tray 20 in the present invention can also be constructed in a form that can be raised and lowered. Specifically, when the tray 20 is lowered, a wheelchair or the like can be driven onto the tray 20, and then the tray 20 is raised and connected to the entrance 101, so that the wheelchair on the tray 20 can pass through the entrance 101 and enter the vehicle body 10, thereby moving the wheelchair or the like into the vehicle body 10; conversely, the wheelchair in the vehicle body 10 can also pass through the entrance 101 and drive onto the raised tray 20, and then the tray 20 is lowered, and the wheelchair can be driven off the tray 20, thereby completing the movement of the wheelchair out of the vehicle body 10. In other words, the tray 20 is connected to the vehicle body 10 in a liftable manner, and when the tray 20 is raised, the tray 20 is suitable for docking with the entrance 101.

[0084] In addition, in some embodiments of the present invention, a joint 105 suitable for docking with the tray rail 21 is provided on the transition rail 13. Optionally, a matching portion is provided on the tray rail 21 or the tray 20, and the matching portion is configured to be suitable for cooperating with the joint 105 to dock the tray rail 21 with the transition rail 13. Through the cooperation between the joint 105 and the matching portion, the shaking of the transition rail 13 relative to the tray rail 21 can be limited, thereby forming a relatively stable guide structure, and realizing stable travel of the wheelchair.

[0085] The matching portion in the present invention may be the guide portion 202 in the following embodiments. For example, the matching portion is set as the end of the guide portion 202 .

[0086] The joint 105 may include a slider, and a slide groove is provided on the tray guide rail 21, and the transition guide rail 13 is limited by the cooperation between the slider and the slide groove. In addition, the present invention also provides other structures for limiting the connection between the tray guide rail 21 and the transition guide rail 13. It should also be noted that the guide portion 202 in the present invention can be provided on the tray 20, or the guide portion 202 can be provided on the tray guide rail 21.

[0087] Alternatively, if Fig.10 In order to further improve the connection effect between the transition rail 13 and the tray rail 21, the transition rail 13 in the present invention has a first wedge surface 104. Specifically, the lower surface of the end of the transition rail 13 has the first wedge surface 104, and the first wedge surface 104 is configured to be inclined toward the upper surface of the transition rail 13 in a direction away from the one end of the transition rail 13. Fig.10 When the transition rail 13 is laid flat, the first wedge surface 104 is arranged on the lower surface of the outer end (the end suitable for extending out of the entrance and exit 101) of the transition rail 13, and the first wedge surface 104 is inclined upward in the direction extending into the carriage 11. The tray rail 21 has a second wedge surface 201, which is opposite to the first wedge surface 104, and the first wedge surface 104 and the second wedge surface 201 are butted up and down when the tray 20 is raised. Among them, the second wedge surface 201 is arranged on the upper surface of the end of the tray rail 21 close to the transition rail 13, and the second wedge surface 201 gradually inclines downward in the direction close to the transition rail 13, and the inclination direction of the first wedge surface 104 is consistent with the inclination direction of the second wedge surface 201, so that when the first wedge surface 104 and the second wedge surface 201 cooperate, the tray rail 21 and the transition rail 13 are combined into a continuous guide structure.

[0088] Optionally, the tray 20 is configured to be connected to the carriage 11 so as to be rotatable up and down, and the tray 20 is configured to be suitable for being rotated upward to be stored in the carriage 11. In this way, after the use of the tray 20 is completed, the tray 20 can also be rotated and placed in the carriage 11 to improve the driving stability of the vehicle 100 and facilitate use. In order to facilitate the use of the vehicle 100, the transition guide 13 can be set to a form that can rotate with the tray 20, that is, when the tray 20 rotates upward, the other end of the transition guide 13 can move along the tray 20, thereby simplifying the use of the vehicle 100.

[0089] Optionally, in some embodiments of the present invention, a guide portion 202 is provided on the tray 20 or the tray guide rail 21, and the joint 105 and the guide portion 202 cooperate with each other so that when the tray 20 rotates, the joint 105 can move along the guide portion 202, thereby realizing the rotation of the transition guide rail 13 driven by the tray 20, and the tray 20 and the transition guide rail 13 can be conveniently and quickly stored in the car 11, thereby improving the practicality of the vehicle 100 and simplifying the operation of the vehicle 100. Of course, in order to further improve the stability and safety of the vehicle 100, the transition guide rail 13 in the present invention can be fixed by a fixed structure after being rotated into the car 11.

[0090] The guide portion 202 in the present invention may be arranged on the tray rail 21, or may be arranged on the tray 20. The guide portion 202 may be in the form of extending along the tray rail 21 or in a direction parallel to the tray rail 21.

[0091] There are various combinations of the connector 105 and the guide portion 202 in the present invention. The present invention describes the following combinations of the connector 105 and the guide portion 202.

[0092] In some examples of the present invention, the joint 105 may include a roller, the guide portion 202 may include a guide rail, and the roller may be rollably matched with the corresponding guide rail, so as to achieve stable rotation of the transition guide rail 13 during the rotation of the tray 20. Optionally, the guide rail in this embodiment may be groove-shaped or convex-shaped. For example, an annular groove may be provided on the roller, the guide portion 202 may be provided as a convex-shaped guide rail, and the guide portion 202 may be slidably embedded in the annular groove, so that during the rolling of the roller, the convex-shaped guide rail cooperates with the annular groove on the roller, so as to guide the rotation of the transition guide rail 13 by rolling along the guide rail; for another example, the guide portion 202 may be provided as a long strip-shaped groove, and the roller may be rollably embedded in the groove, so that when the tray 20 drives the transition guide rail 13 to rotate, the roller may be rollably supported in the guide portion 202, so as to guide the rotation of the transition guide rail 13 by rolling along the guide portion 202.

[0093] Of course, the joint 105 and the guide portion 202 in the present invention can also be configured in other forms. For example, the joint 105 can be configured to include a slide groove, and the guide portion 202 can be configured to include a slider, and at least a portion of the slider can be embedded in the slide groove to improve the stability of the transition guide rail 13 sliding along the guide portion 202. In addition, the joint 105 can also be configured to include a slider, and the guide portion 202 can be configured to include a slide groove. In the present invention, the structure in which the slider and the slide groove are interlocked with each other can also improve the stability of the guide rail sliding along the guide portion 202.

[0094] In addition, the tray rail 21 and the transition rail 13 in the present invention can be set to a shape similar to the car rail 12. For example, the tray rail 21 and the transition rail 13 in the present invention can be constructed in the form of a groove, a convex strip, a plate or a crossbeam. Similarly, the present invention includes two tray rails 21 arranged opposite to each other. Similar to the car rail 12, the spacing between the two tray rails 21 in the present invention is adjustable or fixed. In addition, for the transition rail 13, the spacing between the two transition rails 13 can be set and adjusted according to the tray rail 21, and the present invention will not repeat it. In other words, the spacing between the two tray rails 21 in the present invention is adjustable or fixed, and the spacing between the two transition rails 13 is adjustable or fixed. In addition, in combination with other embodiments of the present invention, the transition rail 13 can be set in a form connected to the car rail 12, so that the transition rail 13 can be adjusted following the car rail 12.

[0095] As can be seen from the above, the guide structure in the present invention has a variety of different forms, and the different forms of the tray guide rails 21 and the transition guide rails 13 can be combined into different embodiments. For example, the shapes of the car guide rails 12, the tray guide rails 21 and the transition guide rails 13 are set to be the same, for example, a guide channel is constructed between two car guide rails 12, a guide channel is constructed between two tray guide rails 21, and a guide channel is also constructed between two transition guide rails 13. In addition, the car guide rails 12, the tray guide rails 21 and the transition guide rails 13 can also be set in different forms, for example, a guide channel is constructed between two tray guide rails 21, a guide channel is constructed between two car guide rails 12, and the two transition guide rails 13 are respectively constructed as guide rail structures.

[0096] In addition, in some specific embodiments of the present invention, the rear of the carriage 11 is provided with an entrance 101, the tray 20 is arranged at the rear of the carriage 11 so as to be liftable and rotatable, the carriage guide rail 12 extends in the front-to-back direction, and the carriage guide rail 12 includes two carriage guide rails arranged oppositely along the left and right sides, and the carriage guide rail 12 beam is arranged on the inner bottom surface of the carriage 11. The tray guide rail 21 extends in the front-to-back direction, and the tray guide rail 21 includes two carriage guide rails arranged oppositely along the left and right sides, and the tray guide rail 21 beam is arranged on the inner bottom surface of the tray 20. Optionally, the two transition guide rails 13 are respectively connected to the two carriage guide rails 12, and the transition guide rails 13 can be rotated up and down relative to the corresponding carriage guide rails 12. When the tray 20 is raised, the two transition guide rails 13 are respectively connected to the two tray guide rails 21 to construct two guide rails extending forward and backward at intervals from left to right, and when the tray 20 is rotated, the end of the transition guide rail 13 is suitable for sliding along the tray guide rail 21. Thereby, stable guidance of the travel direction of the wheelchair is achieved, and the travel stability of the wheelchair is improved. Furthermore, a first wheelchair passage extending in the front-to-rear direction is constructed between the two carriage rails 12; a second wheelchair passage extending in the front-to-rear direction is constructed between the two tray rails 21, and a third wheelchair passage extending in the front-to-rear direction is suitable for being constructed between the two transition rails 13.

[0097] In order to facilitate the travel of the wheelchair, the inner sides of the car guide rails 12, the tray guide rails 21 and the transition guide rails 13 can be constructed into smooth surfaces, so that the car guide rails 12, the tray guide rails 21 and the transition guide rails 13 will not have sufficient friction to allow the wheelchair to flip over the guide rails.

[0098] Optionally, combined Figure 1 as well as Fig. 20 , Fig.21 , seats 103 are provided in the carriage 11, wherein at least one of the two opposite sides of the carriage rail 12 is provided with a seat 103. In the present invention, the carriage rail 12 is provided in the carriage 11, and the carriage rail 12 will occupy a certain space. At this time, the number and placement position of the seats 103 in the carriage 11 can be rotated according to the space of the carriage 11. For example, the seat 103 can be provided on one side of the carriage rail 12, or the seats 103 can be provided on both opposite sides of the carriage rail 12. According to the size of the internal space of the vehicle 100, the placement of the seat 103 and the carriage rail 12 is improved to increase the carrying capacity of the vehicle 100. Since the carriage rail 12 is provided in the carriage 11 in the present application, the travel direction of the wheelchair can be limited, so that the wheelchair can be prevented from deviating from the predetermined position and colliding with the seat 103, thereby improving the safety of the wheelchair user and the person on the seat 103.

[0099] like Fig.18 and Fig.19The vehicle 100 of the present invention further includes a guide plate 22, which is rotatably connected to the tray 20. The guide plate 22 has a first flat position where it is flatly placed on the floor of the vehicle body 10. The guide plate 22 connects the tray 20 and the floor of the vehicle body 10 in the first flat position. During use, when the tray 20 is connected to the entrance 101, the guide plate 22 can be laid flat. At this time, the tray 20 and the vehicle body 10 are connected together by the guide plate 22, so that the spacing or gap between the tray 20 and the vehicle body 10 does not affect the movement of the wheelchair between the vehicle body 10 and the tray 20, thereby improving the stability of the wheelchair during movement.

[0100] In addition, the present invention further provides a transition guide rail 13, and the guidance of the wheelchair or the like is achieved through the cooperation between the guide plate 22 and the transition guide rail 13, thereby further improving the stability of the wheelchair or the like during movement.

[0101] The transition guide rail 13 is rotatably connected to the vehicle body 10 in the up-down direction, thereby improving the stability of the wheelchair guide, and because the transition guide rail 13 is rotatable, the rotation of the guide plate 22 is convenient, the control of the vehicle 100 is convenient, the stability of the wheelchair is improved, and the safety and stability of the vehicle 100 are improved.

[0102] In some embodiments of the present invention, the edge of the guide plate 22 is provided with a clearance groove 204 corresponding to the transition guide rail 13, and the transition guide rail 13 is suitable for being embedded in the clearance groove 204. During the rotation of the guide plate 22, due to the clearance effect of the clearance groove 204, the influence on the transition guide rail 13 can be reduced, and the gravity of the transition guide rail 13 can be prevented from affecting the rotation of the guide plate 22.

[0103] In addition, in other embodiments of the present invention, a carriage guide rail 12 and a tray guide rail 21 are provided, and by providing a clearance groove 204, a stable combination between the transition guide rail 13 and the tray guide rail 21 can be easily achieved, thereby improving the guiding effect for wheelchairs, etc.

[0104] Optionally, the transition guide rail 13 includes a plurality of transition guide rails 13 arranged at intervals along the width direction of the entrance and exit 101 , and the guide plate 22 has a plurality of clearance grooves 204 corresponding to the plurality of transition guide rails 13 .

[0105] In addition, the tray 20 in the present invention can be set in a lifting form. During the lifting process of the tray 20, the guide plate 22 can be set to limit the position of the wheelchair or the like on the tray 20. For example, the guide plate 22 is set in a form of being erected on the tray 20. Since a plurality of clearance grooves 204 are provided, the guide plate 22 still has the function of limiting the position of the wheelchair or the like, so as to prevent the wheelchair or the like from crossing the guide plate 22 and getting stuck during the lifting process of the tray 20. Moreover, the provision of a plurality of clearance grooves 204 also ensures the guiding function of the guide plate 22 in connecting the tray 20 and the floor of the vehicle body 10 to a certain extent.

[0106] In addition, the width of the give way groove 204 in the present invention is not less than the width of the corresponding position on the transition guide rail 13. Thus, the give way function of the give way groove 204 can be effectively realized, the problems caused by the misalignment of the transition guide rail 13 and the give way groove 204 can be reduced or avoided, the requirements for production accuracy can be reduced, and the service life can be extended, and the problem of misalignment of the give way groove 204 and the transition guide rail 13 caused by aging and compression deformation of the guide plate 22 can be avoided. In addition, the size difference between the give way groove 204 and the transition guide rail 13 in the width direction in the present invention should not be set too large to avoid adverse effects on the structural strength of the guide plate 22. Therefore, in the present invention, the width difference between the give way groove 204 and the transition guide rail 13 can be within the range of 0 to 50 mm. For example, the width difference between the give way groove 204 and the transition guide rail 13 is set at 5 mm, 20 mm, 25 mm, 45 mm, etc. Of course, the above description of the width difference between the give way groove 204 and the transition guide rail 13 is only some specific implementation methods of the present invention, and is not a limitation on the protection scope of the present invention. The width difference between the give way groove 204 and the transition guide rail 13 in the present invention can also be set to be greater than 50 mm.

[0107] In addition, in order to achieve stable matching between the clearance groove 204 and the transition guide rail 13, the opening of the clearance groove 204 can be configured to be a bell-mouth shape. Thus, the clearance groove 204 can achieve stable yielding of the transition guide rail 13. In addition, the clearance groove 204 can also be set to have a certain guiding function to fine-tune the position of the transition guide rail 13 and prevent the transition guide rail 13 from deviating.

[0108] Optionally, in some embodiments of the present invention, the tray 20 is connected to the vehicle body 10 in a liftable manner, and when the tray 20 is raised, the tray 20 is suitable for docking with the entrance 101. At this time, the guide plate 22 can also have a first stop position, and the guide plate 22 stands upright relative to the tray 20 at the first stop position. Specifically, when the guide plate 22 is at the first stop position, the guide plate 22 stands upright on the tray 20, and at this time, it can have a certain limiting effect on the wheelchair on the tray 20, preventing the wheelchair from sliding off the tray 20.

[0109] Specifically, during use, when the tray 20 is lowered to the ground, the guide plate 22 can be set to the first stop position, and when a wheelchair or the like is moved into the tray 20 from the other side of the tray 20, the guide plate 22 can limit the position of the wheelchair or the like. Then, the tray 20 is raised, and during the process of the tray 20 being raised, the guide plate 22 is in the first stop position, which can position the wheelchair or the like and prevent the wheelchair or the like from sliding off the tray 20; when the tray 20 rises to the vicinity of the entrance 101, the transition guide rail 13 may interfere with the guide plate 22. At this time, since the yielding groove 204 is provided, the yielding groove 204 can yield to the transition guide rail 13, and the transition guide rail 13 is embedded in the yielding groove 204, and the guide plate 22 will not lift the transition guide rail 13, or the guide plate 22 can only lift the transition guide rail 13 to a limited extent; When the tray 20 is lifted up to connect with the entrance and exit 101, the guide plate 22 can be rotated to a position flat on the floor of the vehicle body 10 to form a passage connecting the tray 20 and the internal space of the vehicle body 10. At this time, due to the provision of the give way groove 204, the transition guide rail 13 has limited or no effect on the guide plate 22 from the first stop position to the first flat position, so as to avoid or reduce the influence of the gravity of the transition guide rail 13 on the rotation of the guide plate 22, so that the guide plate 22 can be rotated to the first flat position more stably, and the wheelchair can be moved into the vehicle body 10 at this time.

[0110] When a wheelchair needs to be moved out of the vehicle body 10, the guide plate 22 can be set in a flat position, the wheelchair can be moved from the vehicle body 10 to the tray 20, and then the guide plate 22 is rotated to the first stop position, and then the transition guide rail 13 is lowered to put the wheelchair on the ground.

[0111] In addition, combined Figures 1 to 8 In the present invention, a baffle 23 is also provided on the tray 20. The baffle 23 is rotatably connected to the tray 20. The baffle 23 has a second flat position and a second stop position. The baffle 23 extends outward relative to the tray 20 in the second flat position. That is, the baffle 23 extends out of the tray in the flat position and extends outward relative to the tray, so that the baffle 23 can be extended to the bottom surface to facilitate the entry of a wheelchair or the like into the tray. The baffle 23 is erected on the tray 20 in the second stop position to provide protection for the wheelchair or the like on the tray 20.

[0112] The baffle 23 is arranged on the side of the tray 20 away from the floor of the vehicle body 10. The baffle 23 can be used to guide the wheelchair to enter and exit the tray 20 and provide a stop limit for the wheelchair. Specifically, after the tray 20 is lowered (slope type, telescopic or lifting type, etc.), the baffle 23 can be rotated outward to the ground, thereby providing a passage from the ground to the tray 20 for the wheelchair. When the wheelchair moves to the tray 20, the baffle 23 can be erected on the tray 20, thereby stopping the wheelchair in another direction and preventing the wheelchair from sliding off the tray 20. Improve stability; then the tray 20 can be raised. In addition, the process of moving the wheelchair out of the vehicle body 10 is the reverse process of the above process.

[0113] Optionally, the baffle plate 23 and the guide plate 22 are respectively disposed on opposite sides of the tray 20 .

[0114] Optionally, the vehicle 100 of the present invention further includes a damping mechanism, which is connected to the guide plate 22 and the tray 20, respectively, and is configured to provide damping for the rotation of the guide plate 22. This can improve the stability of the guide plate 22 during rotation, and can also provide a supporting force for the guide plate 22. During the lifting and lowering process of the tray 20, if a wheelchair pushes the guide plate 22, the positioning effect of the damping mechanism can further prevent the wheelchair from sliding off the tray 20.

[0115] A specific embodiment of the present invention is described below with reference to the accompanying drawings.

[0116] Combination Figures 1 to 21A carriage guide rail 12 is provided in the carriage 11 of the vehicle 100 to limit the direction of travel of the wheelchair. The carriage guide rail 12 is generally straight and includes two carriage guide rails 12 provided at positions opposite to the casters on both sides of the wheelchair. The carriage guide rail 12 has a certain height so that the front wheels of the wheelchair cannot pass over, and the four wheels of the wheelchair are driven along the carriage guide rail 12 from the inside until they reach a designated position (forward or backward) in the carriage 11. When the wheelchair enters a designated position in the carriage 11, a limiting structure 102 is provided so that the front wheels of the wheelchair cannot move forward any further, so that the wheelchair can be accurately parked at the designated position, wherein the limiting structure 102 can be a limiting block, and the limiting blocks can be relatively provided on the left and right sides of the carriage 11, so as to improve the limiting effect of the limiting structure 102. A wheelchair lifting elevator 30 is provided at the rear of the vehicle 100, and the wheelchair lifting elevator 30 is connected to a pallet 20, and the pallet 20 can be lifted and lowered by the elevator 30. A pallet guide rail 21 is provided on the pallet 20, and the pallet guide rail 21 includes two pallet guide rails 21 arranged at positions opposite to the casters on both sides of the wheelchair. In addition, an inner guide plate 212 is added to the rear end of the pallet 20, and two left and right guide grooves 203 are constructed between the inner guide plate 212 and the two tray guide rails 21, respectively. Both ends of the guide groove 203 have open trumpet mouths. When the length of the guide groove 106 is constant, the open trumpet mouth is convenient for guiding the forward wheels of the wheelchair regardless of whether the wheelchair enters or exits. Among them, the inner guide plate 212 and the surface of the tray guide rail 21 have an extremely low friction coefficient (the wheelchair caster can slide). As long as the front wheel of the wheelchair enters the flared end of the guide groove 203, the front wheel will roll or even slide into the deep of the guide groove 203 under the restriction of the inner guide plate 212 and the tray guide rail 21, correcting the driving direction of the wheelchair, thereby ensuring that the wheelchair can enter and exit the vehicle 100 along the guide rail. A transition guide rail 13 is provided between the carriage guide rail 12 and the tray guide rail 21. When the tray 20 is lifted to be flush with the floor of the carriage 11, the transition guide rail 13 connects the carriage guide rail 12 and the tray guide rail 21 to form a continuous guide channel groove, so that the wheelchair can smoothly enter the carriage 11 or exit the tray 20; when the wheelchair exits the tray 20, the tray 20 is lowered to the ground, and the wheelchair exits the tray 20 under the restriction of the tray guide rail 21 and drives to the ground. On the contrary, when a wheelchair enters the vehicle 100 from the ground, it first enters the tray 20. After the tray 20 is lifted, the tray rail 21 automatically docks with the end of the transition rail 13, thereby forming a front-to-back continuous guide channel groove. After the wheelchair enters or exits, the tray 20 is folded upward and stowed. At this time, one end of the transition rail 13 slides to the upper part of the tray rail 21, and is folded upright together with the tray 20 at the rear of the vehicle body 10, thereby closing the vehicle door and completing the whole process of use.
