Technical Field
[0001] Cross - reference to Related Applications This disclosure claims the priority of Chinese Patent Application No. 202221359702.5, filed on May 30, 2022, the entire content of which is incorporated herein by reference.
[0002] This disclosure relates to the field of vehicle grab - rail technology, and in particular, to a vehicle grab - rail assembly and a vehicle.
Background Art
[0003] A grab - rail assembly can be installed on a fixed grab - rail of a vehicle (such as a bus, a coach, or a subway). The grab - rail assembly provides a gripping position for passengers. However, in related technologies, the grab - rail assembly is typically fixed in the used state. When no passengers are using the grab - rail assembly of the vehicle, the grab - rail assembly fixed in the used state occupies the space where passengers stand, thereby reducing the utilization rate of the space inside the vehicle.

The first axis extends along a first direction, and the second axis extends along a second direction. The second axis is rotatably connected to the first axis. One end of the first axis is rotatably connected to a mounting base. The first rotation axis is the central axis of the first rotating shaft, and the second rotation axis is the central axis of the second rotating shaft. A first groove and a second groove are formed in the mounting base, both of which are concaved along a third direction. The third direction is perpendicular to both the first direction and the second direction. The first groove extends in the first direction, and the second groove extends in the second direction. One end of the first groove is formed as a first open end that can be passed through by a rotary grab rail, and the other end of the first groove is connected to the second groove. One end of the second groove is formed as a second open end that can be passed through by a rotary grab rail.
[0015] In the use state, a part of the rotary grab rail is accommodated in the first groove, and in the storage state, a part of the rotary grab rail is accommodated in the second groove.
[0016] In one embodiment, the first groove has two first side walls facing each other in the second direction and a first bottom wall located between the two first side walls. A first elastic limiting member is disposed on both first side walls, and a first elastic buffer member is disposed on the first bottom wall. In the use state, the rotary grab rail is clamped between the two first elastic limiting members and / or
[0017] The second groove has two second side walls facing each other in the first direction and a second bottom wall located between the two second side walls. A second elastic limiting member is disposed on both second side walls, and a second elastic buffer member is disposed on the second bottom wall. In the storage state, the rotary grab rail is clamped between the two second elastic limiting members.
[0018] In one embodiment, the mounting base includes a first compartment and a second compartment. A mounting plate is provided in the first compartment, and one end of the first shaft is rotatably connected to the mounting plate. A first notch is formed in the first compartment. A second notch is formed in the second compartment, and the second compartment is detachably connected to the first compartment. The first groove is defined by the second compartment together with the first notch, and the second groove is defined by the second notch together with the mounting plate.
[0019] In one embodiment, the mounting base is provided with a through hole, and the through hole is designed such that the fixed grab rail of the vehicle can pass through. The mounting base includes a first compartment and a third compartment. The first compartment has a first semi-hole, and the third compartment has a second semi-hole. The first compartment is detachably connected to the third compartment, so that the first semi-hole and the second semi-hole can be joined together to form a through hole.
[0020] In one embodiment, the vehicle grab rail assembly further includes a limiting member, and a limiting groove is formed in the limiting member. The limiting groove extends along a second direction. In the stored state, one end of the movable rod away from the fixed rod is received in the limiting groove.
[0021] In one embodiment, the limiting groove has two third side walls facing each other in a first direction and a third bottom wall located between the two third side walls. Third elastic limiting members are disposed on both third side walls, and a third elastic buffer member is disposed on the third bottom wall. In the stored state, the movable rod sandwiches one end away from the fixed rod between the two third elastic limiting members.
[0022] On the other hand, the present disclosure also provides a vehicle including the aforementioned vehicle grab rail assembly.
[0023] In one embodiment, the vehicle further includes a backrest. The mounting base of the vehicle grab rail assembly is located on one side of the backrest. In the use state, the rotary grab rail is placed on that side of the backrest, and in the storage state, the rotary grab rail is placed behind the backrest.
[0024] In one embodiment, the vehicle further includes a fixed grab rail extending along a third direction, which is the vertical direction of the vehicle. The first direction is the longitudinal direction of the vehicle, and the second direction is the lateral direction of the vehicle. The fixed grab rail is spaced apart from the side portion of the vehicle body along the lateral direction. The mounting base of the vehicle grab rail assembly is installed on the fixed grab rail.
[0025] A bending stopper is formed on the fixed grab rail and is located above the mounting base. The distance between the bending stopper and the mounting base in the vertical direction is greater than the minimum length of the rotary grab rail of the vehicle grab rail assembly and less than or equal to the distance between the bending stopper and the side portion of the vehicle body in the lateral direction.
[0026] In the vehicle grab rail assembly provided by the present disclosure, the fixed rod of the rotary grab rail can rotate around a first rotation axis (extending along a first direction) with respect to the mounting base, and can further rotate around a second rotation axis (extending along a second direction perpendicular to the first direction) with respect to the mounting base, thereby enabling the rotary grab rail to switch between a use state and a storage state. When a passenger needs to use the rotary grab rail, the passenger can rotate the rotary grab rail to the use state to prepare a gripping position for the passenger. When a passenger does not need to use the rotary grab rail, the passenger can rotate it to the storage state to avoid the rotary grab rail occupying the passenger's standing space and improve the space utilization of the vehicle. Further, since the movable rod of the rotary grab rail is movably connected to the fixed rod along the length direction of the rotary grab rail, when the rotary grab rail is in the use state, the movable rod can be moved along the fixed rod to adjust the length of the rotary grab rail. That is, the overall length of the rotary grab rail is adjustable, enabling the length of the rotary grab rail to be adjusted according to the needs of the passengers, thereby enhancing the applicability of the rotary grab rail.
[0027] Other features and advantages of the present disclosure are provided in the following detailed description.
[0028] The foregoing and / or additional aspects and advantages of the present disclosure will become apparent and be readily appreciated from the description of the embodiments in combination with the following accompanying drawings.

Best Mode for Carrying Out the Invention
[0030] Embodiments of the present disclosure are described in detail below, and examples thereof are illustrated in the figures. Identical or similar reference numerals represent identical or similar elements, or elements having the same or similar functions throughout. The embodiments described with reference to the figures are exemplary and are intended to illustrate the present disclosure and should not be construed as a limitation on the present disclosure.
[0031] In the present disclosure, unless otherwise specified, orientation terms such as "first direction A, second direction B, third direction C" specifically mean those illustrated in FIGS. 1 to 3, and "up, down, left, right, front, back" generally mean above, below, left, right, front, and back of the vehicle under normal operating conditions, and "inside and outside" mean the inside and outside of the corresponding structural outer shape.
[0032] As shown in FIGS. 1 to 19, according to a first aspect of the present disclosure, the present disclosure provides a vehicle grab rail assembly 10 including a mounting base 1 and a rotary grab rail 2. The rotary grab rail 2 includes a fixed rod 21 and a movable rod 22. The fixed rod 21 may be rotatably connected to the mounting base 1 around a first rotation axis L1 extending in a first direction A and a second rotation axis L2 extending in a second direction B. The first direction A is perpendicular to the second direction B. The movable rod 22 is movably connected to the fixed rod 21 along the length direction of the rotary grab rail 2. The rotary grab rail 2 can be switched between a use state and a storage state. In the use state, the rotary grab rail 2 extends in the first direction A, and in the storage state, the rotary grab rail 2 extends in the second direction B.
[0033] In the vehicle grab rail assembly 10 of the present disclosure, when the rotary grab rail 2 is in the retracted state, it extends in the second direction B. During the process of switching the rotary grab rail 2 from the retracted state to the use state, the fixing rod 21 of the rotary grab rail 2 extending in the second direction B rotates around the first rotation axis L1 extending in the first direction A so as to rotate the rotary grab rail 2 to a position extending in the first direction A, that is, to rotate the rotary grab rail 2 to the use state, and then can rotate around the second rotation axis L2 extending in the second direction B perpendicular to the first direction A.
[0034] Through the above technical solution, in the vehicle grab rail assembly 10 provided by the present disclosure, the fixing rod 21 of the rotary grab rail 2 can rotate around the first rotation axis L1 (extending in the first direction A) with respect to the mounting base 1, and can further rotate around the second rotation axis L2 (extending in the second direction B perpendicular to the first direction A) with respect to the mounting base 1, thereby enabling the rotary grab rail 2 to switch between the use state and the retracted state. When a passenger needs to use the rotary grab rail 2, the passenger can rotate it to the use state, thereby preparing a gripping position for the passenger. When the passenger does not need to use the rotary grab rail 2, the passenger can rotate it to the retracted state, thereby avoiding the rotary grab rail 2 occupying the passenger's standing space and improving the space utilization of the vehicle. Furthermore, since the movable rod 22 is movably connected to the fixing rod 21 along the length direction of the rotary grab rail 2, when the rotary grab rail 2 is in the use state, the movable rod 22 can be moved along the fixing rod 21 to adjust the length of the rotary grab rail 2. That is, the overall length of the rotary grab rail 2 is adjustable, enabling the length of the rotary grab rail 2 to be adjusted according to the needs of the passengers, thereby enhancing the applicability of the rotary grab rail 2.
[0035] The vehicle grab rail assembly 10 provided by the present disclosure can be used by any passenger in the vehicle who needs a gripping position, and the present disclosure does not limit this. In one embodiment, the vehicle grab rail assembly 10 provided by the present disclosure can be placed in the wheelchair area of the vehicle, thereby providing a gripping position for wheelchair users. Since the rotary grab rail 2 of the vehicle grab rail assembly 10 can be switched between a use state and a storage state, the rotary grab rail 2 can be arranged in the storage state when the wheelchair 40 does not enter the wheelchair area or when the wheelchair 40 needs to leave the wheelchair area. Thereby, it is avoided that the grab rail assembly 10 obstructs the wheelchair 40 entering or leaving the wheelchair area, and it is possible for the wheelchair 40 to enter or leave the wheelchair area from any direction. When the wheelchair 40 is parked in the wheelchair area, the rotary grab rail 2 can be rotated to the use state, thereby providing a gripping position for wheelchair users.
[0036] Here, it should be noted that the first direction A and the second direction B of the present disclosure may be any directions, and the present disclosure does not limit this. In one embodiment, the first direction A may be the longitudinal direction of the vehicle, and the second direction B may be the lateral direction of the vehicle. When the rotary grab rail 2 is in the storage state, it may extend in the lateral direction. When the rotary grab rail 2 is in the use state, it may extend in the longitudinal direction. During the process of switching the rotary grab rail 2 from the storage state to the use state, the fixed rod 21 of the rotary grab rail 2 extending in the lateral direction can first rotate around the first rotation axis L1 extending in the longitudinal direction to an intermediate state. At this point, the rotary grab rail 2 in the intermediate state extends in the vertical direction of the vehicle. Then, the rotary grab rail 2 extending in the vertical direction can rotate around the second rotation axis L2 extending in the lateral direction so as to rotate the rotary grab rail 2 to a position extending in the longitudinal direction, that is, to rotate the rotary grab rail 2 to the use state.
[0037] The rotary grab rail 2 may be connected to the fixed rod 21 in any suitable manner such that the movable rod 22 can move along the length direction of the rotary grab rail 2. In one embodiment, one end of the movable rod 22 may be movably inserted into the fixed rod 21, or one end of the fixed rod 21 may be movably inserted into the movable rod 22, and the present disclosure does not limit this.
[0038] Since the movable rod 22 is movably connected to the fixed rod 21, in order to lock the movable rod 22 to the fixed rod 21, in one embodiment, as shown in FIGS. 4 to 6, the rotary grab rail 2 may further include a locking member 23 and an elastic member 24. One end of the movable rod 22 may be movably inserted into the fixed rod 21, and the fixed rod 21 may form a plurality of locking holes 211. The locking member 23 and the elastic member 24 may be disposed inside the movable rod 22. A first through hole 222 for the locking member 23 to pass through is formed in the movable rod 22. One end of the elastic member 24 can abut against the locking member 23, and the elastic member 24 is used to apply an elastic force to the locking member 23 to move the locking member 23 toward the fixed rod 21 so that the locking member 23 can extend into the locking hole 211.
[0039] When adjusting the length of the rotary grab rail 2, since the movable rod 22 is movably connected to the fixed rod 21, the overall length of the rotary grab rail 2 can be adjusted by pulling the movable rod 22. The movable rod 22 is equipped with a locking member 23 and an elastic member 24, and since the elastic member 24 is in contact with the locking member 23, the elastic member 24 can apply an elastic force to the locking member 23 to move the locking member 23 toward the fixed rod 21. When the movable rod 22 is pulled and moves relative to the fixed rod 21, and the first through hole 222 of the movable rod 22 is aligned with the locking hole 211 of the fixed rod 21, the locking member 23 can pass through the first through hole 222 of the movable rod 22 under the elastic force of the elastic member 24 and enter the locking hole 211 of the fixed rod 21. Thereby, the movable rod 22 is locked to the fixed rod 21, that is, the position of the movable rod 22 is fixed, and the rotary grab rail 2 is fastened in the adjusted length, thus facilitating use for passengers.
[0040] A plurality of locking holes 211 may be formed in the fixed rod 21, and these locking holes 211 may be spaced apart along the length direction of the rotary grab rail 2. Therefore, when the movable rod 22 is pulled and moves relative to the fixed rod 21, the locking member 23 can pass through the first through hole 222 of the movable rod 22 and enter any one of the plurality of locking holes 211 of the fixed rod 21, thereby enabling the rotary grab rail 2 to be adjusted to different lengths.
[0041] In one embodiment, as shown in FIGS. 5 and 6, the locking member 23 may include a locking body and a stop flange 233. The stop flange 233 may protrude radially outward from the locking body. The locking body may include a first section 231 and a second section 232, and the stop flange 233 may be positioned between the first section 231 and the second section 232. One end of the elastic member 24 may pass through the first section 231 and abut against the stop flange 233, while the other end of the elastic member 24 may abut against the inner wall of the movable rod 22. When the first through-hole 222 of the movable rod 22 is not aligned with the locking hole 211 of the fixed rod 21, the elastic member 24 is in a compressed state. When the movable rod 22 is pulled and moves relative to the fixed rod 21 so that the first through-hole 222 of the movable rod 22 is aligned with the locking hole 211 of the fixed rod 21, the elastic force accumulated in the elastic member 24 in its compressed state is released, thereby applying an elastic force to the stop flange 233 by the elastic member 24, enabling the second section 232 of the locking body to pass through the first through-hole 222 of the movable rod 22 and enter the locking hole 211 of the fixed rod 21, thus locking the movable rod 22.
[0042] In one embodiment, as shown in FIGS. 5 and 6, a containing cavity 221 is formed in the movable rod 22, and the locking member 23 and the elastic member 24 may be disposed therein. An inward protrusion 2211 is formed on the wall of the containing cavity 221. One end of the elastic member 24 may pass through the first section 231 of the locking body, and the other end of the elastic member 24 may pass through the protrusion 2211.
[0043] In order to reduce the sliding friction between the movable rod 22 and the fixed rod 21, in one embodiment, as shown in FIGS. 4, 5, and 7, the rotary grab rail 2 may further include a sliding sleeve 25. The sliding sleeve 25 may be disposed between the movable rod 22 and the fixed rod 21. The outer peripheral surface of the sliding sleeve slides against the inner peripheral surface of the fixed rod. A gap 8 exists between the outer peripheral surface of the movable rod 22 and the inner peripheral surface of the fixed rod 21. Due to the presence of the sliding sleeve 25 between the movable rod 22 and the fixed rod 21 and the slidable engagement of the outer peripheral surface of the sliding sleeve 25 with the inner peripheral surface of the fixed rod 21, the movable rod 22 can slide within the fixed rod 21 via the sliding sleeve 25. In the portion of the movable rod 22 where the sliding sleeve 25 is installed, the movable rod 22 can slide within the fixed rod 21 via the sliding sleeve 25. In the portion of the movable rod 22 where the sliding sleeve 25 is not installed, since the sliding sleeve 25 is attached to the outside of the movable rod 22, a gap 8 exists between the outer peripheral surface of the movable rod 22 and the inner peripheral surface of the fixed rod 21. That is, during the movement of the movable rod 22 relative to the fixed rod 21, the sliding sleeve 25 can prevent direct contact between the movable rod 22 and the fixed rod 21, thereby reducing friction and facilitating the reduction of the frictional force when the movable rod 22 is moved.
[0044] The sliding sleeve 25 may be installed at any suitable position of the movable rod 22. For example, in one embodiment of the present disclosure, as shown in FIG. 5, the sliding sleeve 25 may be installed at the end of the movable rod 22 close to the mounting base 1. In this way, the movable rod 22 can slide against the side wall of the inner peripheral surface of the fixed rod 21 via the sliding sleeve 25 and can also slide against the top wall of the inner peripheral surface of the fixed rod 21, thereby reducing the friction between the movable rod 22 and the top wall of the inner peripheral surface of the fixed rod 21 when the movable rod 22 is stored in the fixed rod 21.
[0045] In other embodiments, the movable rod 22 may also be inserted through the sliding sleeve 25 to enable the sliding sleeve 25 to be installed at an intermediate position within the movable rod 22.
[0046] In one embodiment, as shown in FIG. 7, the sliding sleeve 25 may have a second through hole 251 formed therethrough for the locking member 23 to pass through.
[0047] In one embodiment, as shown in FIGS. 5 and 7, the rotary grab rail 2 may include a first fastener 27, a first connecting hole 252 is formed in the sliding sleeve 25, and a second connecting hole is formed in the movable rod 22. The first fastener 27 can pass through the first connecting hole 252 and be connected to the second connecting hole, so that the sliding sleeve 25 is installed on the movable rod 22.
[0048] In order to prevent the sliding sleeve 25 from coming out of the fixed rod 21, in one embodiment, as shown in FIGS. 4 and 8, a stop sleeve 26 may be installed at one end of the fixed rod 21 away from the mounting base 1 and may be used to stop the sliding sleeve 25. When adjusting the length of the rotary grab rail 2, the movable rod 22 moves towards the above-mentioned end away from the mounting base 1. Since the stop sleeve 26 is installed at the end of the fixed rod 21 away from the mounting base 1, when the movable rod 22 is pulled and slides within the fixed rod 21, the stop sleeve 26 can be used to stop the sliding sleeve 25 moving towards the stop sleeve 26, thereby preventing the sliding sleeve 25 from coming out of the fixed rod 21, that is, the sliding sleeve 25 can be prevented from coming out of the fixed rod 21.
[0049] In one embodiment, as shown in FIGS. 8 and 9, the rotary grab rail 2 may include a second fastener 28, and an installation groove 261 may be formed in the stopper. The fixed rod 21 may have a third connection hole 212, and the second fastener 28 can pass through the third connection hole 212 and be connected to the installation groove 261, whereby the stop sleeve 26 can be installed on the fixed rod 21.
[0050] In order to facilitate the movement of the movable rod 22, in one embodiment, the rotary grab rail 2 may further include a driving device. The driving device may be provided inside the fixed rod 21 and may be connected to the movable rod 22. The driving device is used to drive the movable rod 22 relative to the fixed rod 21. When the rotary grab rail 2 is rotated to the use state, the driving device can be controlled to drive the movable rod 22 outwardly relative to the fixed rod 21, whereby the length of the rotary grab rail 2 can be adjusted. When the rotary grab rail 2 is moved in a direction away from the use state position, the driving device can be controlled to drive the movable rod 22 inwardly relative to the fixed rod 21, thereby enabling the movable rod 22 to be stored in the fixed rod 21 and avoiding the rotary grab rail 2 occupying space.
[0051] The driving device may be a cylinder, a hydraulic cylinder, or a linear motor, and the present disclosure does not limit this.
[0052] In the rotary grab rail 2 of the present disclosure, the fixed rod 21 may be realized by any suitable means for rotating along a first rotation axis L1 and a second rotation axis L2 relative to the mounting base 1. For example, in one embodiment, one end of the fixed rod 21 may be formed as a ball head, and the mounting base 1 may have a ball socket that fits the ball head. Therefore, the fixed rod 21 may rotate 360° relative to the mounting base 1, that is, the fixed rod 21 may rotate along the first rotation axis L1 and the second rotation axis L2 relative to the mounting base 1.
[0053] In other embodiments, as shown in FIG. 3, the vehicle grab rail assembly 10 may further include a first axis 3 and a second axis 4. The first axis 3 may extend in a first direction A, and the second axis 4 may extend in a second direction B. The second axis 4 may be rotatably connected to the first axis 3, and one end of the first axis 3 may be rotatably connected to the mounting base 1. The first rotation axis L1 is the central axis of the first axis 3, and the second rotation axis L2 is the central axis of the second axis 4. Since the first rotation axis L1 is the central axis of the first axis 3, the first axis 3 rotatably connected to the mounting base 1 can rotate along its own central axis with respect to the mounting base 1, thereby enabling the rotary grab rail 2 to rotate around the first rotation axis L1. Since the second rotation axis L2 is the central axis of the second axis 4, the second axis 4 rotatably connected to the first axis 3 can rotate along its own central axis with respect to the first axis 3, thereby enabling the rotary grab rail 2 to rotate around the second rotation axis L2.
[0054] In order to provide a space within the mounting base 1 for accommodating the rotary grab rail 2, in one embodiment, as shown in FIGS. 10 and 11, a first groove and a second groove are formed in the mounting base. Both the first groove 14 and the second groove 15 may be recessed along a third direction. The third direction is perpendicular to both the first direction A and the second direction B. The first groove 14 extends along the first direction A, and the second groove 15 extends along the second direction B. One end of the first groove 14 is formed as a first open end 145 through which the rotary grab rail 2 can pass, and the other end of the first groove 14 is connected to the second groove 15. One end of the second groove 15 is formed as a second open end 153 through which the rotary grab rail 2 can pass. In the use state, a part of the rotary grab rail 2 is accommodated in the first groove 14, and in the storage state, a part of the rotary grab rail 2 is accommodated in the second groove 15.
[0055] When the rotary grab rail 2 is in use, the rotary grab rail 2 may extend along the first direction A, and a part of the rotary grab rail 2 may be accommodated in the first groove 14 while extending along the first direction A. Another part of the rotary grab rail 2 may pass through the first open end 145 of the first groove 14, and thus may extend from the mounting base 1 to provide a gripping position for passengers. When the rotary grab rail 2 is in the stored state, the rotary grab rail 2 may extend along the second direction B, and a part of the rotary grab rail 2 may be accommodated in the second groove 15 while extending along the second direction B. Another part of the rotary grab rail 2 may extend from the second open end 153 of the second groove 15.
[0056] In order to prevent the rotary grab rail 2 accommodated in the first groove 14 from swaying and making noise during the operation of the vehicle, in one embodiment, as shown in FIG. 12, the first groove 14 may have two first side walls 141 facing each other in the second direction B and a first bottom wall 142 located between the two first side walls 141. The first elastic limiting member 143 is disposed on both of the first side walls 141, and the first elastic buffer member 144 is disposed on the first bottom wall 142. In the use state, the rotary grab rail 2 is clamped between the two first elastic limiting members 143.
[0057] When the rotary grab rail 2 is in use, due to the first elastic limiting members 143 being present on both first side walls 141 of the first groove 14, the rotary grab rail 2 housed in the first groove 14 can be clamped between the two first elastic limiting members 143. Under the clamping force of the two first elastic limiting members 143, the rotary grab rail 2 can be maintained in a state for passengers to grip, and the clamping force can prevent the rotary grab rail 2 from swaying against the first groove 14 and making noise during vehicle operation. A first elastic buffer member 144 is provided on the first bottom wall 142 of the first groove 14, and the first elastic buffer member 144 can apply a buffer force to the rotary grab rail 2 when the rotary grab rail 2 fits into the first groove 14. By wrapping the rotary grab rail 2 housed in the first groove 14 with the two first elastic limiting members 143 and the first elastic buffer member 144, it is possible to prevent the rotary grab rail 2 from directly contacting the two first side walls 141 and the first bottom wall 142 of the first groove 14, and to prevent the rotary grab rail 2 from hitting the first side wall 141 and the first bottom wall 142 during vehicle operation.

The first elastic limiting member 143 may be provided with a fourth connection hole 1431, and the first side wall 141 may be provided with a fifth connection hole 1411. The third fastener 61 can be connected to the fifth connection hole 1411 through the fourth connection hole 1431, thereby installing the first elastic limiting member 143 on the first side wall 141. The first elastic buffer member 144 may be provided with a sixth connection hole 1441, and the first bottom wall 142 may be provided with a seventh connection hole 1421. The fourth fastener 62 can be connected to the seventh connection hole 1421 through the sixth connection hole 1441, thereby installing the first elastic buffer member 144 on the first bottom wall 142.
[0059] In order to prevent the rotary grab rail 2 housed in the second groove 15 from shaking and generating noise during vehicle operation, in one embodiment, as shown in FIGS. 11 and 12, the second groove 15 may have two second side walls 151 facing each other along the first direction A and a second bottom wall 152 located between the two second side walls 151. Second elastic limiting members are disposed on both of the second side walls 151, and a second elastic buffer member is disposed on the second bottom wall 152. In the stored state, the rotary grab rail 2 is clamped between the two second elastic limiting members.
[0060] When the rotary grab rail 2 is in the stored state, due to the presence of the second elastic limiting members on both of the second side walls 151 of the second groove 15, the rotary grab rail 2 housed in the second groove 15 can be clamped between the two second elastic limiting members. Under the clamping force of the two second elastic limiting members, the rotary grab rail 2 can be maintained in the stored state, and the clamping force can prevent the rotary grab rail 2 from shaking against the second groove 15 and generating noise during vehicle operation. A second elastic buffer member may be provided on the second bottom wall 152 of the second groove 15, and the second elastic buffer member can apply a buffer force to the rotary grab rail 2 when the rotary grab rail 2 fits into the second groove 15. By wrapping the rotary grab rail 2 housed in the second groove 15 with the two second elastic limiting members and the second elastic buffer member, it is possible to prevent the rotary grab rail 2 from directly contacting the two second side walls 151 and the second bottom wall 152 of the second groove 15, and from hitting the second side walls 151 and the second bottom wall 152 during vehicle operation.
[0061] In one embodiment, as shown in FIGS. 11 and 12, in order to prevent the rotary grab rail 2 from rattling and making noise when switching between the first groove 14 and the second groove 15 during vehicle operation, a first elastic limiting member 143 may be provided on the first side wall 141, and a first elastic buffer member 144 may be provided on the first bottom wall 142. Similarly, a second elastic limiting member may be provided on the second side wall 151, and a second elastic buffer member may be provided on the second bottom wall 152. Therefore, the rotary grab rail 2 does not produce rattling and noise when it is in either the first groove 14 or the second groove 15.
[0062] In one embodiment, the first elastic limiting member 143, the first elastic buffer member 144, the second elastic limiting member, and the second elastic buffer member may all be rubber pads.
[0063] In order to facilitate the cleaning of the first groove 14 and the second groove 15, in one embodiment, as shown in FIGS. 11, 13, and 14, the mounting base 1 may include a first compartment 11 and a second compartment 12. A mounting plate 111 may be provided in the first compartment 11, and one end of the first shaft 3 may be rotatably connected to the mounting plate 111. A first notch 112 is formed in the first compartment 11. A second notch 121 is formed in the second compartment 12, and the second compartment 12 is detachably connected to the first compartment 11. The first groove 14 is defined by the second compartment 12 together with the first notch 112, and the second groove 15 is defined by the second notch 121 together with the mounting plate 111.
[0064] Since one end of the first shaft 3 can be rotatably connected to the mounting plate 111 of the first compartment 11, when the first shaft 3 rotates relative to the mounting plate 111 along its own central axis, it can rotate the rotary grab rail 2 along the first rotation axis L1.
[0065] The first groove 14, together with the second section 12, is defined by a first notch 112 formed in the first section 11, and the second groove 15, together with the mounting plate 111 formed in the first section 11, is defined by a second notch 121 formed in the second section 12. Since the second section 12 can be detachably connected to the first section 11, it may be convenient to clean the first groove 14 and the second groove 15 by removing the second section 12 from the first section 11.
[0066] In one embodiment, as shown in FIG. 12, the vehicle grab rail assembly 10 may further include a fifth fastener 63. The second section 12 may be provided with an eighth connection hole 1211, and the first section 11 may be provided with a ninth connection hole 114. The fifth fastener 63 can pass through the eighth connection hole 1211 and be connected to the ninth connection hole 114, thereby enabling the second section 12 to be detachably connected to the first section 11.
[0067] In one embodiment, as shown in FIGS. 3 and 13, the vehicle grab rail assembly 10 may further include a first shaft sleeve 71, a second shaft sleeve 72, a first gasket 73, and a locking nut 74. The first shaft sleeve 71 may be attached to the first shaft 3, and the mounting plate 111 may be provided with a first mounting hole 1111.

That one end of the first shaft 3 passing through the second shaft sleeve 72 may be attached to the first gasket 73. The first shaft 3 is screwed to the locking nut 74, and the locking nut 74 is used to lock the first shaft 3 in the axial direction.
[0068] In one embodiment, as shown in FIGS. 3, 13, and 16, the vehicle grab rail assembly 10 may further include a third shaft sleeve 75, a second gasket 76, and a locking ring 77. An end of the first shaft 3 that does not pass through the first mounting hole 1111 may be formed with a second mounting hole 31. The third shaft sleeve 75 may be disposed within the second mounting hole 31. One end of the second shaft 4 may pass through the third shaft sleeve 75 and be attached to the second gasket 76. That end of the second shaft 4 passing through the second mounting hole 31 may be formed with a groove. The locking ring 77 may engage with the groove to axially lock the second shaft 4.
[0069] In one embodiment, both the second shaft sleeve 72 and the third shaft sleeve 75 may be made of nylon material.
[0070] To facilitate the installation of the mounting base 1 to the fixed grab rail 20 of the vehicle, in one embodiment, as shown in FIGS. 11, 13, and 15, the mounting base 1 may be provided with a through hole 16. The through hole 16 is designed such that the fixed grab rail 20 of the vehicle passes through it. The mounting base 1 includes a first section 11 and a third section 13. The first section 11 is provided with a first half hole 113, and the third section 13 is provided with a second half hole 131. The first section 11 is detachably connected to the third section 13, and thus the first half hole 113 and the second half hole 131 can be assembled to form the through hole 16.
[0071] The through hole 16 for the vehicle fixed grab rail 20 to pass through is assembled from a first half hole 113 formed in the first section 11 and a second half hole 131 formed in the third section 13. Thereby, the manufacturing accuracy requirements for the first half hole 113 and the second half hole 131 can be reduced, and thus the production of the mounting base 1 can be promoted. The first section 11 may be detachably connected to the third section 13. By removing the first section 11 from the third section 13, the mounting base 1 can be removed from the fixed handrail rod 20, which makes it easier to perform maintenance on the removed mounting base 1.
[0072] In one embodiment, as shown in FIGS. 12, 13, and 15, the vehicle grab rail assembly 10 may further include a sixth fastener 64 and a seventh fastener 65. The first section 11 may be provided with a tenth connection hole 115, and the third section 13 may be provided with an eleventh connection hole 132. The sixth fastener 64 can pass through the tenth connection hole 115, and the seventh fastener 65 can pass through the eleventh connection hole 132. The sixth fastener 64 can be connected to the seventh fastener 65, thereby enabling the first section 11 to be detachably connected to the third section 13.
[0073] In one embodiment, as shown in FIGS. 17 and 18, the vehicle grab rail assembly 10 may further include a restricting member 5. A restricting groove 51 may be provided in the restricting member 5. The restricting groove 51 may extend along the second direction B. In the stored state, the end portion of the movable rod 22 away from the fixed rod 21 may be received in the restricting groove 51. When the rotary grab rail 2 is rotated to the stored state, the rotary grab rail 2 may extend along the second direction B. The movable rod 22 of the rotary grab rail 2 may move relative to the fixed rod 21 and may be stored in the fixed rod 21. The end portion of the movable rod 22 away from the fixed rod 21 may be received in the restricting groove 51 extending along the second direction B. Thereby, it is possible to prevent the rotary grab rail 2 from occupying an excessively large space in the stored state, and by storing the movable rod 22 in the restricting groove 51, it is also possible to prevent the movable rod 22 from hitting other parts of the vehicle.
[0074] In one embodiment, as shown in FIGS. 17 and 18, when the second direction B is the left - right direction of the vehicle, by receiving the end portion of the movable rod 22 away from the fixed rod 21 in the restricting groove 51, it is possible to prevent the movable rod 22 from damaging the window 50 located on the side portion of the vehicle body.
[0075] In one embodiment, as shown in FIGS. 17 and 18, the restricting member 5 may be attached to the fixed grab rail 20 of the vehicle.
[0076] In order to prevent the rotary grab rail 2 housed in the limiting groove 51 from swaying and generating noise during the operation of the vehicle, in one embodiment, as shown in FIG. 18, the limiting groove 51 has two third side walls 511 facing each other along the first direction A and a third bottom wall 512 located between the two third side walls 511. A third elastic limiting member 513 is disposed on both of the third side walls 512, and a third elastic buffer member 514 is disposed on the third bottom wall 512. In the stored state, one end of the movable rod 22 away from the fixed rod 21 is clamped between the two third elastic limiting members 513.
[0077] When the rotary grab rail 2 is in the stored state, due to the presence of the third elastic limiting members 513 on both of the third side walls 511 of the limiting groove 51, the rotary grab rail 2 housed in the limiting groove 51 can be clamped between the two third elastic limiting members 513. Under the clamping force of the two third elastic limiting members 513, the rotary grab rail 2 can be maintained in the limiting groove 51, and the clamping force can prevent the rotary grab rail 2 from swaying and generating noise with respect to the limiting groove 51 during vehicle operation. A third elastic buffer member 514 is provided on the third bottom wall 512 of the limiting groove 51, and the third elastic buffer member 514 can apply a buffering force to the rotary grab rail 2 when the rotary grab rail 2 fits into the limiting groove 51. The rotary grab rail 2 housed in the limiting groove 51 may be wrapped by the third elastic limiting member 513 and the third elastic buffer member 514, and the rotary grab rail 2 can avoid direct contact between the rotary grab rail 2 and the two third side walls 511 and the third bottom wall 512 of the limiting groove 51, and prevent collision with the third side walls 511 and the third bottom wall 512 during vehicle operation.
[0078] According to another aspect of the present disclosure, the present disclosure provides a vehicle including the vehicle grab rail assembly 10 described above.
[0079] In order to avoid the rotating grab rail 2 occupying the standing space of passengers in the stowed state, in one embodiment, as shown in FIGS. 1 and 2, the vehicle further includes a backrest 30. The mounting base 1 of the vehicle grab rail assembly 10 is located on one side of the backrest 30. In the use state, the rotating grab rail 2 is placed on that side of the backrest 30, and in the stowed state, the rotating grab rail 2 is placed behind the backrest 30. Since the mounting base 1 is located on one side of the backrest 30, when the rotating grab rail 2 is rotated to the use state, the rotating grab rail 2 is placed on that side of the backrest 30, and the rotating grab rail 2 can be used as a handrail for the backrest 30. When the rotating grab rail 2 is rotated to the stowed state, the rotating grab rail 2 is placed behind the backrest 30, thereby reducing the space occupied by the rotating grab rail 2 in the stowed state, which is beneficial for improving the space utilization of the vehicle.
[0080] In one embodiment, as shown in FIGS. 1 and 2, when a passenger using the vehicle grab rail assembly 10 provided by the present disclosure is a wheelchair user, the wheelchair 40 may be parked in front of the backrest 30 of the vehicle with the backrest of the wheelchair leaning against the backrest 30 of the vehicle.
[0081] In one embodiment, the vehicle may further include a wheelchair fixing strap. When the wheelchair 40 is parked in front of the backrest 30 of the vehicle, the wheelchair 40 can be fixed using the wheelchair fixing strap, thereby preventing the wheelchair 40 from sliding.
[0082] In order to prevent the rotary grab rail 2 from damaging the window 50 located on the side of the vehicle body, in one embodiment, as shown in FIGS. 17 and 19, the vehicle further includes a fixed grab rail 20. The fixed grab rail 20 extends along a third direction C, and the third direction C is the vertical direction of the vehicle. The first direction A is the longitudinal direction of the vehicle, and the second direction B is the lateral direction of the vehicle. The fixed grab rail 20 may be separated from the side of the vehicle body in the lateral direction, and the mounting base 1 of the vehicle grab rail assembly 10 may be attached to the fixed grab rail 20. The fixed grab rail 20 may be provided with a bending stopper 201, and the bending stopper 201 may be located above the mounting base 1. The distance between the bending stopper 201 and the mounting base 1 in the vertical direction is greater than the minimum length of the rotary grab rail 2 of the vehicle grab rail assembly 10, and it is less than or equal to the distance between the bending stopper 201 and the side of the vehicle body in the lateral direction.
[0083] When the length of the rotary grab rail 2 is less than the distance D1 between the bending stopper 201 and the mounting base 1 in the vertical direction, the rotary grab rail 2 can rotate past the bending stopper 201 to the retracted state. Since the distance D1 between the bending stopper 201 and the mounting base 1 in the vertical direction is less than or equal to the distance D2 between the bending stopper 201 and the side of the vehicle body in the lateral direction, when the rotary grab rail 2 passes the bending stopper 201, the length of the rotary grab rail 2 is less than the distance D2 between the bending stopper 201 and the side of the vehicle body, thereby preventing the rotary grab rail 2 from damaging the window 50 located on the side of the vehicle body. Since the distance D1 between the bending stopper 201 and the mounting base 1 in the vertical direction is greater than the minimum length of the rotary grab rail 2 of the vehicle grab rail assembly 10, this ensures that when the movable rod 22 of the rotary grab rail 2 is fully retracted into the fixed rod 21, the rotary grab rail 2 can pass the bending stop member 201 and rotate to the retracted state.
