One object of the present invention is to provide a vehicle 100, wherein the vehicle 100 of the present invention can be a welfare vehicle, welfare vehicle or other vehicle 100 suitable for carrying. The vehicle 100 is suitable for carrying wheelchairs and users who take wheelchairs, and is also suitable for carrying wheelchair beds, transportation carts, and the like.

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are illustrative and intended to explain the present invention and should not be construed as limiting the present invention.

Referring to fig. 1 to 13, a vehicle 100 according to an embodiment of the present invention includes a vehicle body 10 and a tray 20, the vehicle body 10 having an access opening 101, the tray 20 being connected to the vehicle body 10, and the tray 20 being adapted to interface with the access opening 101 to form a passageway into and out of the vehicle body 10. When the tray 20 is brought into contact with the doorway 101, equipment such as a wheelchair can enter the vehicle body 10 through the tray 20 or can exit the vehicle body 10 through the tray 20. The entrance 101 can be arranged at the tail of the vehicle body 10, and the wheelchair enters and exits from the tail of the vehicle body 10; the doorway 101 may be provided on a side surface of the vehicle body 10, and the wheelchair may enter and exit from the side surface of the vehicle body 10; the doorway 101 may be provided at another position of the vehicle body 10 as necessary. In the present invention, the wheelchair is mainly described as an example, but this is not intended to limit the scope of the present invention, and the tray 20 may be provided to allow other devices (e.g., a transport vehicle, a wheelchair bed, etc.) to be driven in and out.

The vehicle 100 of the present invention further includes a guide 22, the guide 22 being rotatably coupled to the tray 20, the guide 22 having a first flat position lying on the floor of the vehicle body 10, the guide 22 coupling the tray 20 and the floor of the vehicle body 10 in the first flat position. When the tray 20 is connected with the gateway 101 in use, the guide plate 22 can be laid flat, and at this time, the tray 20 and the vehicle body 10 are connected together through the guide plate 22, so that the movement of a wheelchair and the like between the vehicle body 10 and the tray 20 is prevented from being influenced by the space or clearance between the tray 20 and the vehicle body 10, and the stability of the movement process of the wheelchair and the like is improved.

In addition, the invention also provides a transition guide rail 13, and the guide plate 22 is matched with the transition guide rail 13 to realize the guide of wheelchairs and the like, thereby further improving the stability of the wheelchairs and the like in the moving process.

In addition, a deviation may occur during the process of the wheelchair and the like entering into or exiting from the vehicle body 10 through the tray 20, and particularly, in the case of the wheelchair having a motor-driven wheel, the deviation is more likely to occur, and in order to facilitate the use of the tray 20, as shown in fig. 1 to 8, a transition guide 13 is provided in the present invention, the transition guide 13 is rotatably connected to the vehicle body 10, and the transition guide 13 is adapted to protrude from the entrance 101 and cooperate with the tray 20 to guide between the tray 20 and the vehicle body 10. The transition 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 when the wheelchair or the like enters the vehicle body 10 from the tray 20 or moves from the vehicle body 10 to the tray 20.

Wherein the transition guide rail 13 is rotatably connected to the vehicle body in the up-down direction. Taking the car body connected with a lifting tray as an example, when the tray 20 is lifted horizontally between the plane of the carriage and the ground, the guide plate 22 is convenient to rotate; the transition rail 13 can rotate with the tray 20 as the tray 20 rotates between the vertical storage of the car and the plane of the car. Of course, the pallet of the present invention may be in other forms, such as a slope type pallet, and the stability of the wheelchair or the like during traveling may be improved by the transition rail 13.

In some embodiments of the present invention, as shown in fig. 11 and 13, the edge of the guide plate 22 is provided with an abdication slot 204 corresponding to the transition rail 13, and the transition rail 13 is adapted to be inserted into the abdication slot 204. In the rotating process of the guide plate 22, due to the yielding function of the yielding groove 204, the influence on the transition guide rail 13 can be reduced, and the influence on the rotation of the guide plate 22 caused by the gravity action of the transition guide rail 13 can be avoided.

In addition, in other embodiments of the present invention, the car rail 12 and the tray rail 21 are provided, and the concessional groove 204 is provided, so that stable connection between the transition rail 13 and the tray rail 21 can be easily achieved, and the guiding effect for wheelchairs and the like can be improved.

Alternatively, the transition guide 13 includes a plurality of transition guide rails 13 arranged at intervals in the width direction of the doorway 101, and the guide plate 22 has a plurality of relief grooves 204 corresponding to the plurality of transition guide rails 13.

In addition, in the process of the horizontal lifting of the tray 20 between the carriage plane and the ground, the guide plate 22 can be arranged to limit the wheelchair and the like on the tray 20, for example, the guide plate 22 is arranged to be vertically arranged on the tray 20; due to the arrangement of the plurality of the abdicating grooves 204, the guide plate 22 is not influenced by the transition guide rail 13, and the guide plate still has the function of limiting the wheelchair and the like, so that the wheelchair and the like are prevented from passing over the guide plate 22 and being clamped and the like in the lifting process of the tray 20.

In addition, the width of the avoiding groove 204 in the present invention is not less than the width of the corresponding position on the transition rail 13. Therefore, the abdicating effect of the abdicating groove 204 can be effectively realized, the problem caused by the misalignment of the transition guide rail 13 and the abdicating groove 204 is reduced or avoided, the requirement on the production precision is reduced, the service life is prolonged, and the problem that the abdicating groove 204 and the transition guide rail 13 are misaligned due to the aging and compression deformation of the guide plate 22 is avoided. In addition, the dimension difference between the relief groove 204 and the transition rail 13 in the width direction in the present invention should not be set too large, so as to avoid the influence of too large gap on the passage of the wheelchair and the like. Therefore, the present invention can make the width difference between the abdicating groove 204 and the transition rail 13 in the range of 0 to 50 mm. For example, the width difference between the relief groove 204 and the transition rail 13 is set to be 5 mm, 20 mm, 25 mm, 45 mm, and the like. Of course, the above description of the width difference between the abdicating groove 204 and the transition rail 13 is only some specific embodiments of the present invention, and is not intended to limit the scope of the present invention, and the width difference between the abdicating groove 204 and the transition rail 13 in the present invention may also be set to be greater than 50 mm.

In addition, in order to achieve stable fitting of the abdicating groove 204 and the transition rail 13, the opening of the abdicating groove 204 may be formed in a bell mouth shape. Therefore, stable abdicating of the abdicating groove 204 on the transition guide rail 13 can be realized, and in addition, the abdicating groove 204 can be set to have a certain guiding function so as to finely adjust the position of the transition guide rail 13 and prevent the deviation of the transition guide rail 13.

The support rod 14 is rotatably connected with the vehicle body 10 and the transition guide rail 13, so that the clamping can be avoided, and the stability is improved. Alternatively, a pump body structure can be provided to form a driving structure for driving the transition guide rail 13 to rotate in combination with the support rod 14.

In addition, the support bar 14 of the present invention is rotatably connected to at least one of the vehicle body 10 and the transition rail 13 about a fixed axis, thereby further optimizing the limiting effect on the rotational direction of the transition rail 13.

In some embodiments of the present invention, the orientation mechanism further comprises a shaft 151.

Thereby, the pressure pipe can rotate around a fixed axis relative to the vehicle body 10, and the guiding effect of the directional rotation of the transition guide rail 13 is improved. In addition, when the pressure pipe is connected with the vehicle body 10 through the rotating shaft 151, the piston rod may be connected with the transition guide rail 13 through the rotating shaft 151, and other hinge forms (for example, universal hinges) may also be used between the piston rod and the transition guide rail 13, so that only one of the support rod 14 and the vehicle body 10 and the transition guide rail 13 needs to rotate around a fixed rotation axis, and the connection of the support rod 14 with the other one of the vehicle body 10 and the transition guide rail 13 does not affect the rotation, so as to achieve effective limitation on the rotation direction of the transition guide rail 13.

Alternatively, a pivot 151 may be provided between the piston rod and the transition rail 13, and the pivot 151 may be rotatably connected about its axis to one of the piston rod and the transition rail 13.

Wherein the second bracket 153 is coupled to the upper surface of the tray rail 21 when the tray rail 21 is laid flat.

Referring to fig. 18 to 20, 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 vehicle body 10 and the transition rail 13, and the other of the vehicle body 10 and the transition rail 13 is provided with a guide groove 106, and the guide plate 17 is movably inserted into the guide groove 106. That is, the guide plate 17 is fixedly connected with the vehicle body 10, and the transition guide rail 13 is provided with the guide groove 106, and the transition guide rail 13 can rotate along the guide plate 17; alternatively, the guide plate 17 is fixedly connected with the transition guide rail 13, the vehicle body 10 is provided with a guide groove 106, and the guide plate 17 is rotatably connected with the vehicle body 10. When the guide plate 17 is inserted into the guide groove 106 and slides along the guide groove 106, the guide plate 17 is fixedly connected with one of the vehicle body 10 and the transition guide rail 13, so that the transition guide rail 13 rotates along the extending direction of the guide plate 17, and the rotation direction of the transition guide rail 13 is limited.

The guide plate 17 in the present invention may be configured as a linear guide rail, an arc guide rail, a broken line guide rail, etc., and all of them may implement the limitation of the rotation direction of the transition guide rail 13. In one embodiment of the present invention, the guide plate 17 is configured in a circular arc plate shape, and the central axis of the guide plate 17 coincides with the rotational central axis of the transition rail 13; or the central axis of the guide plate 17 is parallel and close to the rotational central axis of the transition rail 13. Therefore, the guide plate 17 can be slidably inserted into the guide groove 106, and the guide plate 17 can stably slide relative to the guide groove 106. Furthermore, the size of the guide groove 106 can be reduced, and the influence of the installation of the guide groove 106 on the structural strength of the transition rail 13 can be reduced.

Optionally, a limiting portion 171 may be further provided on the guide plate 17, and the limiting portion 171 is configured to limit the transition rail 13 when the transition rail 13 is rotated to a predetermined position. In other words, when the transition rail 13 is rotated to a predetermined position in one direction (e.g., a direction of rotation from the guide position toward the storage position or a direction of rotation from the storage position toward the guide position in the present invention), the stopper portion 171 stops the transition rail 13 from approaching the vehicle body 10 to restrict the transition rail 13 from continuing to rotate in that direction by a large angle. The transition guide rail 13 is limited by the limiting part 171, so that the transition guide rail 13 is conveniently and stably controlled.

Specifically, the transition rail 13 may have a guiding position and a receiving position, and the limiting portion 171 is configured to limit the transition rail 13 at the guiding position and/or the receiving position. For example, the stopper 171 may be provided to limit the transition rail 13 at the storage position; for another example, the stopper 171 may be provided to stop the transition rail 13 at the guide position.

Alternatively, the guide plate 17 may be fixedly connected to the vehicle body 10, and the guide groove 106 is disposed on the transition rail 13, such that when the transition rail 13 rotates along one direction, the distance between the transition rail 13 and the limiting portion 171 gradually decreases, and when the transition rail 13 rotates along the one direction to a predetermined position, the limiting portion 171 will limit the transition rail 13 to continue rotating along the one direction.

In addition, the guide plate 17 may be fixedly connected to the transition rail 13, and the guide groove 106 is disposed on the vehicle body 10, so that when the transition rail 13 rotates in one direction, the distance between the limiting portion 171 and the vehicle body 10 gradually decreases, and when the transition rail 13 rotates to a predetermined position in the one direction, the limiting portion 171 limits the transition rail 13 to continue rotating in the one direction.

The limiting portion 171 includes a limiting post disposed on the guide plate 17, and the limiting post protrudes out of the surface of the guide plate 17 and is adapted to limit the transition guide rail 13. For example, the guide plate 17 may be configured in a semicircular arc shape with an opening facing downward, and a stopper post may be provided at an intermediate position or an end position of the guide plate 17, or the like, and may protrude from a side surface, an outer circumferential surface, or an inner circumferential surface of the guide plate 17.

In addition, in the foregoing embodiment, since the length of the support rod 14 in which the piston rod is completely retracted or completely extended is fixed, the support rod 14 can position the transition rail 13 after the transition rail 13 is rotated to a predetermined position with respect to the vehicle body 10, so as to conveniently position the transition rail 13. In addition, the guide plate 17 may be combined with the support bar 14 to improve the guide and limit effects on the transition guide rail 13. In this case, the stopper 171 may be provided or not provided on the guide plate 17.

Additionally, the aforementioned orientation mechanisms of the present invention may be associated with the car rail 12 and the transition rail 13, respectively, and configured to limit the rotational direction of the transition rail 13 relative to the car rail 12.
