DETAILED DESCRIPTION

[0019] The core of the present invention is to provide an on-and-off assisting device to assist special groups of people to get off and on the vehicle when there is a height difference in the boarding position, thereby improving the convenience of the rail passenger vehicle.

[0020] The following embodiments are described with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the invention contents described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary as solutions to the inventions described in the claims. It should be noted that, for ease of description, only the parts related to the inventions are shown in the accompanying drawings. The embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0021] When a train encounters an emergency such as fire, collision, derailment, etc., passengers need to get off the train quickly and evacuate to a safe area quickly. In the prior art, in order to deal with such an emergency, an escape ladder is usually used to assist passengers in evacuating through the windows. However, the escape ladder can only realize the basic escape function of ordinary passengers, and does not consider the use of disabled people with limited mobility.

[0022] In order to solve the above problems, an embodiment of the present invention discloses a vehicle getting on and off assisting device, which can be used by disabled persons with limited mobility and has higher usability and applicability.

[0023] like Figure 1-Figure 4As shown, the vehicle boarding and exiting assistance device disclosed in the embodiment of the present invention comprises a support seat, a parking pallet 104, a driving device and a ferry 106. The support seat is a supporting component of the vehicle boarding and exiting assistance device. Considering the stability of the vehicle boarding and exiting assistance device during use, the support seat should have a certain area to reliably bear the weight of the entire vehicle boarding and exiting assistance device, as well as the weight of the wheelchair and the disabled person on the vehicle boarding and exiting assistance device.

[0024] The parking tray 104 is used to carry the wheelchair and the passengers and the luggage that the passengers may carry. The parking tray 104 can be arranged in parallel with the support base, and in the lifting process of the parking tray 104, it is always kept parallel with the support base.

[0025] The driving device is arranged on the support seat, and is used to drive the parking pallet 104 to perform lifting and lowering movements. The specific type of the driving device is not limited, as long as it can provide lifting power for the parking pallet 104 and can adjust the height of the parking pallet 104.

[0026] One end of the ferry board 106 is hinged to the first end of the parking pallet 104, so that the ferry board 106 can swing between the folded position and the use position. When the ferry board 106 is in the use position, the angle between the upper surface of the ferry board 106 and the upper surface of the parking pallet 104 is greater than 180° and less than 270°, that is, the ferry board 106 is connected to the ground by the parking pallet 104. The folded position of the ferry board 106 is a position where the space where the ferry board 106 is located is small, for example, it can be a position perpendicular to the parking pallet 104 (such as Figure 5-Figure 7 As shown), it can also be laid flat on the upper surface of the parking pallet 104. The present embodiment does not limit the folding position of the ferry 106, as long as it can occupy a smaller space to facilitate the storage of the boarding and alighting assistance device when not in use.

[0027] When passengers get off the train, the parking pallet 104 can be raised to the same height as the floor height of the train door, and then the passengers can enter the parking pallet 104 from the second end of the parking pallet 104 in a wheelchair, and then transition to the ground through the ferry 106 to complete the getting off action. It should be noted that when the floor height of the train door is higher than the ground height, the boarding and disembarking auxiliary device can also be used to complete the boarding action. Passengers can climb onto the parking pallet 104 from the inclined ferry 106 in a wheelchair, and enter the carriage from the second end of the parking pallet 104.

[0028] The boarding and getting on / off assistance device provided by the present invention can be placed on a boarding and getting on platform when in use (it should be noted that the boarding and getting on platform refers to the boarding and getting on location, not just the platform of a station, but also includes boarding and getting on location other than a station in an emergency), and according to the height of the entrance and exit floor of the train compartment, the height of the parking pallet 104 is raised by a driving device so that the height of the parking pallet 104 is close to the height of the entrance and exit floor of the train compartment, thereby reducing the height difference between the entrance and exit floor and the boarding platform.

[0029] Since the height of the parking pallet 104 is close to the height of the entrance and exit floor of the train compartment, the wheelchair can be directly pushed onto the parking pallet 104 . If the end of the ferry 106 can touch the ground, the wheelchair can be pushed to the ground through the inclined surface of the ferry 106 .

[0030] If the parking pallet 104 is too high to allow the end of the ferry 106 to touch the ground, the height of the parking pallet 104 is lowered by the driving device so that the end of the ferry 106 can touch the ground, and the wheelchair can be pushed to the ground through the inclined surface of the ferry 106. The boarding and alighting assisting device disclosed in the embodiment of the present invention can reduce the impact of boarding and alighting caused by the height difference between the entrance and exit floor of the train compartment and the boarding platform, and can conveniently and quickly assist special groups to board and alight the train. In an emergency, the speed of evacuating the compartment is increased, and the safety of passengers is ensured.

[0031] In a specific embodiment of the present invention, the driving device may include a scissor-type linkage mechanism 103 and a telescopic driving device. One end of the scissor-type linkage mechanism 103 is disposed on a support seat, and the other end is disposed on a parking support plate 104. Specifically, a corresponding number of linkages may be disposed according to the magnitude of the elevation. The greater the magnitude of the elevation, the more linkage groups are required. For example Figure 1 In the illustrated solution, the scissor-type linkage mechanism 103 has two linkage groups, each of which has two linkage groups.

[0032] The two connecting rods of each connecting rod group are arranged crosswise and hinged in the middle, and the ends of the connecting rods of the two connecting rod groups are hinged. The connecting rod group located at the bottom is arranged on the support seat, for example, the end of one of the connecting rods (for example, the first connecting rod) is hinged on the support seat, and the end of the other connecting rod (for example, the second connecting rod) is slidably matched on the support seat; similarly, the connecting rod group located at the top is connected to the parking pallet 104, for example, the end of one of the connecting rods (for example, the third connecting rod) is hinged on the parking pallet 104, and the end of the other connecting rod (for example, the fourth connecting rod) is slidably matched on the parking pallet 104. Based on this, the deformation of the scissor-type connecting rod mechanism 103 can be achieved by driving the first connecting rod to swing, and then the lifting and lowering of the parking pallet 104 can be achieved; the deformation of the scissor-type connecting rod mechanism 103 can also be achieved by driving the end of the second connecting rod to slide, and then the lifting and lowering of the parking pallet 104 can be achieved.

[0033] One end of the telescopic drive device 108 is arranged on the support seat, and the other end is hinged to a connecting rod of the scissor-type connecting rod mechanism 103. The telescopic drive device 108 can be an electric push rod or a piston cylinder mechanism (such as a hydraulic cylinder and a pneumatic cylinder), that is, by outputting linear motion, a thrust force is generated on the connecting rod, so that the scissor-type connecting rod mechanism 103 is deformed, thereby controlling the lifting and lowering of the parking pallet 104. The telescopic drive device 108 can be fixed on the support seat, and its telescopic rod can be connected to the end of the second connecting rod; the telescopic drive device 108 can also be hinged on the support seat, and its telescopic rod can be hinged to the end of the first connecting rod.

[0034] Furthermore, in order to ensure the smoothness of the lifting and lowering process of the parking pallet 104, a gas spring 109 can be added. One end of the gas spring 109 is hinged to the support seat, and the other end is hinged to the first connecting rod. The damping effect of the gas spring 109 can be used to control the deformation speed of the scissor-type linkage mechanism 103, thereby avoiding the danger caused by a large speed change of the parking pallet 104 due to instantaneous movement when the telescopic drive device 108 starts to output power.

[0035] Furthermore, there can be two scissor-type linkage mechanisms 103 to ensure a more reliable support effect for the parking tray 104. The telescopic drive device can be hinged to the link of the scissor-type linkage mechanism 103 through a connecting rod, and the connecting rod is connected to the links of the same functional position of the two scissor-type linkage mechanisms 103 (for example, connected to the first links of the two scissor-type linkage mechanisms 103, and can also be connected to the second links of the two scissor-type linkage mechanisms 103), and the telescopic drive device is connected to the connecting rod, that is, the telescopic drive device can drive the scissor-type linkage mechanism 103 to deform by applying thrust and tension to the connecting rod, and then control the lifting and lowering of the parking tray 104.

[0036] In this embodiment, the support base includes a base 101 and a leveling foot 102 disposed at the bottom of the base 101. A scissor-type linkage mechanism 103 and a telescopic drive device are disposed on the base 101. The leveling foot 102 can be disposed at the four corners of the base 101. By adjusting the height of the leveling foot 102, the entire vehicle boarding and disembarking assistance device can be kept level on an uneven ground, thereby enhancing the stability of the entire vehicle boarding and disembarking assistance device. The base 101 can be manufactured by welding aluminum profiles so as to be able to bear the weight of the entire vehicle boarding and disembarking assistance device, the wheelchair, and the passenger.

[0037] like Figure 3 As shown, the ferry board 106 may include a plurality of ferry boards, and any two adjacent ferry boards are hinged. When the ferry board 106 is in the folded position, each ferry board rotates to fit the board surface in sequence (such as Figure 5In this embodiment, the ferry board 106 is divided into a plurality of mutually hinged ferry boards, so that when the ferry board 106 is in the folded position, the ferry board 106 can occupy a smaller space; and when the ferry board 106 is in the use position, the ferry board 106 can have a larger use area.

[0038] Further, the hinge connecting any two ferry plates includes a first hinge connecting plate, a second hinge connecting plate, a hinge shaft and a locking nut. For ease of understanding, the ferry plate 106 includes two ferry plates as an example, and the two ferry plates are respectively a first ferry plate 1061 and a second ferry plate 1062.

[0039] The first hinge connecting plate is fixed on one of the splitter plates, for example, fixed on the first splitter plate 1061, and the second hinge connecting plate is fixed on the other splitter plate, for example, fixed on the second splitter plate 1062. The first hinge connecting plate and the second hinge connecting plate are hinged through a hinge shaft, one end of the hinge shaft has a limit portion to prevent the first hinge connecting plate and the second hinge connecting plate from being separated from the hinge shaft, and the other end of the hinge shaft is a screw portion. The locking nut is threadedly engaged with the screw portion. After the locking nut is locked, the first hinge connecting plate and the second hinge connecting plate will be pressed, thereby increasing the rotation resistance of the first hinge connecting plate and the second hinge connecting plate; correspondingly, after loosening the locking nut, the rotation resistance of the first hinge connecting plate and the second hinge connecting plate will be reduced.

[0040] When the ferry board 106 is in the use position, each ferry board is located on the same plane. In this embodiment, taking two ferry boards as an example, the first ferry board 1061 and the second ferry board 1062 can be rotated to be located on the same plane, and then the locking nut is locked to compress the first hinge connecting plate and the second hinge connecting plate, so that the first ferry board 1061 and the second ferry board 1062 are kept on the same plane and can also bear a certain weight. In order to further increase the rotation resistance of the first hinge connecting plate and the second hinge connecting plate, friction teeth can be added to the contact surface of the two. After the locking nut compresses the first hinge connecting plate and the second hinge connecting plate, the friction teeth of the two are engaged with each other, thereby increasing the rotation resistance and improving the load-bearing capacity.

[0041] In addition, the hinge connecting any two ferry boards can also be designed as a self-locking hinge, and the rotation range of the self-locking hinge is limited. For example, when the ferry board 106 is rotated from the folded position to the use position (that is, each ferry board is located in the same plane), the ferry board is limited by the self-locking hinge and cannot continue to rotate, so as to remain in the same plane. The limiting direction can be used to make the ferry board 106 in the use position, and when the upper surface of the ferry board 106 is subjected to force, each ferry board cannot rotate, so that the ferry board 106 is in the use position and can withstand a certain weight.

[0042] Since the boarding and alighting assistance device cannot be arranged close to the carriage, there must be a gap between the floor of the train door and the parking tray 104. If the gap is too large, it will affect the passage of the wheelchair. Based on this, in this embodiment, the boarding and alighting assistance device may also include a limit baffle 105, which is hinged to the second end of the parking tray 104 so that the limit baffle 105 can swing between the folded position and the use position. When the limit baffle 105 is in the use position, the upper surface of the limit baffle 105 and the upper surface of the parking tray 104 have an angle of 160° to 200°.

[0043] In this embodiment, when the boarding and alighting assisting device is used to assist passengers to get off the train, the boarding and alighting assisting device can be arranged at the door of the carriage, and even if there is a gap between the floor of the train door and the parking pallet 104, the gap can be covered by the limit baffle 105. Specifically, the limit baffle 105 can be swung to the use position so that the limit baffle 105 overlaps the floor of the train door to facilitate the passage of the wheelchair.

[0044] When the limit baffle 105 is overlapped on the floor of the train door, if the height of the parking pallet 104 is lower than the floor of the train door, the angle between the upper surface of the limit baffle 105 and the upper surface of the parking pallet 104 will be less than 180°; if the height of the parking pallet 104 is higher than the floor of the train door, the angle between the upper surface of the limit baffle 105 and the upper surface of the parking pallet 104 will be greater than 180°; if the height of the parking pallet 104 is equal to the floor of the train door, the angle between the upper surface of the limit baffle 105 and the upper surface of the parking pallet 104 will be equal to 180°. Preferably, the height of the parking pallet 104 can be raised to the same height as the floor of the train door, so that the upper surface of the limiting baffle 105 and the upper surface of the parking pallet 104 are on the same plane; of course, when the angle between the upper surface of the limiting baffle 105 and the upper surface of the parking pallet 104 is 160°~200°, it will not increase the difficulty of the wheelchair passing.

[0045] Furthermore, the limiting baffle 105 may also include a limiting position. When the limiting baffle 105 is in the limiting position, the plate surface of the limiting baffle 105 is perpendicular to the plate surface of the parking pallet 104, and the limiting baffle 105 is located above the parking pallet 104. After the passenger's wheelchair passes through the limiting baffle 105 and moves onto the parking pallet 104, the limiting baffle 105 can be rotated to the limiting position so that the limiting baffle 105 swings to the top of the parking pallet 104 to prevent the wheelchair from rolling down from the second end of the parking pallet 104. Similarly, if the passenger rises or falls with the parking pallet 104, the ferry 106 can also be rotated to the top of the parking pallet 104 to prevent the wheelchair from rolling down from the first end of the parking pallet 104, thereby improving safety.

[0046] It should be noted that the vehicle boarding and disembarking assisting device may be provided with a locking member for locking the limit baffle 105 in the limit position, so as to keep the limit baffle 105 in the limit position. When the limit baffle 105 is in the folded position, the limit baffle 105 is perpendicular to the parking support plate 104, and the limit baffle 105 is located below the parking support plate 104, and the limit baffle 105 can be folded by utilizing the natural sagging of the limit baffle 105.

[0047] In a specific embodiment of the present invention, the vehicle boarding and disembarking assistance device may further include a holding guardrail handrail 107, which is disposed on the parking pallet 104. There are two holding guardrail handrails 107, which are symmetrically disposed on both sides of the parking pallet 104. After the passenger is on the parking pallet 104, the holding guardrail handrail 107 provides a holding function for the passenger, thereby enhancing the safety of the entire device.

[0048] Furthermore, the guardrail handrail 107 is hinged on the parking pallet 104, so that the guardrail handrail 107 can swing between a folded position and a use position. When the guardrail handrail 107 is in the use position, the guardrail handrail 107 is perpendicular to the parking pallet 104 for passengers to hold. When the guardrail handrail 107 is in the folded position, the guardrail handrail 107 is flat on the upper surface of the parking pallet 104 to reduce the occupied area of ​​the installation and enhance the convenience of the entire device.
