[0054] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0055] Reference Figures 1 to 3 According to a first aspect of this application, a handrail device 100 is provided, the handrail device 100 including a guide rod 10 and a handrail 20, the handrail 20 being sleeved on the guide rod 10, and a drive mechanism 30 being configured to drive the handrail 20 to move up and down along the guide rod 10.

[0056] It is understandable that the handrail 20 rises as the driver and passengers get on the vehicle and falls as they get off.

[0057] The guide rod 10 can be constructed as a rectangular rod, a circular rod, an L-shaped rod, etc.

[0058] In this embodiment, by sleeved the handrail 20 on the guide rod 10, the handrail 20 can be raised and lowered along the guide rod 10 under the drive of the drive mechanism 30. In this way, both the handrail 20 and the guide rod 10 can provide assistance for drivers and passengers to get on and off the vehicle. When the handrail 20 is raised and lowered normally, drivers and passengers can hold onto the handrail 20 to get on and off the vehicle. When the handrail 20 malfunctions, drivers and passengers can hold onto the guide rod 10 to get on and off the vehicle. This helps drivers and passengers to get on and off the vehicle.

[0059] Furthermore, by fitting the handrail 20 onto the guide rod 10, the drive mechanism 30 that drives the handrail 20 to rise and fall and the guide rod 10 that mounts the handrail 20 can be separated, so that the handrail device 100 can be flexibly assembled into the vehicle.

[0060] In some embodiments, the guide rod 10 may be constructed as a hollow rod to reduce the weight of the handrail device 100.

[0061] Reference Figures 1 to 4In some embodiments, the handrail device 100 includes an upper cover 80 and a lower cover 90, with the top of the guide rod 10 connected to the upper cover 80 and the bottom connected to the lower cover 90. The upper cover 80 and the lower cover 90 can be connected to the vehicle using screws or other fasteners, or they can be integrally formed with the vehicle.

[0062] In some embodiments, the drive mechanism 30 includes a first drive member 31 and a first transmission assembly 33. The first transmission assembly 33 is connected to the armrest 20 and is drively connected to the first drive member 31. The first drive member 31 is configured to indirectly drive the armrest 20 to rise and fall via the first transmission assembly 33. With this configuration, the installation position of the first drive member 31 is not limited by the position of the armrest 20, which helps the armrest device 100 to be flexibly assembled into the vehicle.

[0063] The transmission method of the first transmission component 33 can be rope drive, chain drive, belt drive, gear and rack drive, screw drive, etc.

[0064] The first driving component 31 can be located inside the lower cover 90.

[0065] In some embodiments, the first driving element 31 is a motor.

[0066] Reference Figure 4 In some embodiments, the first transmission component 33 includes a first transmission member 331 and a second transmission member 332. The first transmission member 331 is connected to the handrail 20 and is driven by the second transmission member 332. The second transmission member 332 is driven by the first driving member 31. The first driving member 31 indirectly drives the handrail 20 to rise and fall through the first transmission member 331 and the second transmission member 332.

[0067] It can be understood that the first driving component 31 drives the second transmission component 332 to rotate, thereby causing the first transmission component 331 to move, and in turn causing the handrail 20 connected to the first transmission component 331 to rise and fall.

[0068] In some embodiments, the first transmission member 331 can be a flexible member such as a belt, steel rope or chain, so that the first transmission member 331 can be bent to adapt to different transmission paths and narrow space layouts.

[0069] In some embodiments, the first transmission member 331 is a rope, and the second transmission member 332 is a rope pulley. The rope pulley is disposed on the upper cover 80, and the rope is wound around the rope pulley. The first drive member 31 drives the rope pulley to rotate, thereby winding or unwinding the rope, and thus driving the handrail 20 to rise and fall. This arrangement helps to reduce the weight of the handrail device 100.

[0070] Reference Figure 4In some embodiments, the first transmission assembly 33 further includes a third transmission member 333, which is disposed at the bottom of the guide rod 10 and is connected to the first driving member 31. The second transmission member 332 is disposed at the top of the guide rod 10. The first transmission member 331 is connected to the second transmission member 332 and the third transmission member 333. The first driving member 31 indirectly drives the handrail 20 to rise and fall through the first transmission member 331, the second transmission member 332 and the third transmission member 333.

[0071] In some embodiments, the second transmission member 332 is disposed within the upper cover 80, and the third transmission member 333 is disposed within the lower cover 90.

[0072] In some embodiments, the first transmission member 331 is a belt, the second transmission member 332 is a first pulley, and the third transmission member 333 is a second pulley. The belt is tensioned on the first pulley and the second pulley. The handrail 20 is connected to the belt. The first driving member 31 drives the first pulley and the second pulley to rotate, thereby driving the belt to rotate and thus driving the handrail 20 to rise and fall along the guide rod 10.

[0073] In some embodiments, the first transmission component 33 is a rope pulley assembly, the second transmission component 332 and the third transmission component 333 are rope pulleys, the first transmission component 331 is a rope, and the rope is tensioned between the two rope pulleys for effective transmission.

[0074] In some embodiments, the handrail 20 is provided with a first through hole and a second through hole, a rope is passed through and fixed in the first through hole, and a rope is passed through the second through hole and can slide relative to the second through hole.

[0075] Reference Figure 4 In some embodiments, the drive mechanism 30 further includes a second transmission assembly 34, through which the first drive member 31 is driveably connected to the first transmission assembly 33. This helps to change the direction of force transmission, allowing the handrail device 100 to adapt to complex assembly environments.

[0076] It can be understood that the first driving component 31 indirectly drives the first transmission component 33 to operate through the second transmission component 34.

[0077] In some embodiments, the second transmission assembly 34 and the third transmission member 333 are horizontally arranged and both are disposed within the lower cover 90.

[0078] In some embodiments, the second transmission component 34 is configured to operate synchronously with the first drive component 31 under the drive of the first drive component 31, so as to drive the handrail 20 to operate synchronously via the first transmission component 33. It is understood that the second transmission component 34 has a self-locking characteristic, and the lifting direction and lifting speed of the handrail 20 are controlled by the first drive component 31.

[0079] Specifically, during the upward movement of the handrail 20 driven by the first drive component 31 through the second transmission assembly 34 and the first transmission assembly 33, when the handrail 20 is subjected to external upward or downward pulling forces, the second transmission assembly 34 prevents the handrail 20 from rapidly rising off its intended upward speed or from reversing and descending. Similarly, during the downward movement of the handrail 20 driven by the first drive component 31 through the second transmission assembly 34 and the first transmission assembly 33, when the handrail 20 is subjected to external upward or downward pulling forces, the second transmission assembly 34 prevents the handrail 20 from rapidly rising off its intended downward speed or descending. When the first drive component 31 stops, the handrail 20 stops rising and falling. When the handrail 20 is subjected to external upward or downward pulling forces, the second transmission assembly prevents the handrail 20 from being easily lifted or pulled down. This design helps reduce the risk of loss of balance for passengers.

[0080] In some embodiments, the second transmission component 34 includes a worm gear.

[0081] Reference Figure 5 In some embodiments, the second transmission assembly 34 includes a worm gear 341 and a worm 342. The worm gear 341 and worm 342 achieve self-locking based on the friction between the worm 342 and the worm gear 341, the lead angle of the worm 342, and other characteristics. Specifically, the worm gear 341 meshes with the worm 342, with the worm 342 being the driving member and the worm gear 341 being the driven member. The worm 342 is connected to the first driving member 31, and the worm gear 341 is connected to the first transmission assembly 33. The first driving member 31 drives the worm 342 to rotate, thereby driving the worm gear 341 to rotate, which in turn drives the first transmission assembly 33 to move, and subsequently drives the handrail 20 to rise and fall.

[0082] In addition, the transmission structure of the worm gear 341 and worm 342 has a reverse self-locking characteristic, that is, the worm 342 can drive the worm gear 341 to rotate, but the worm gear 341 cannot drive the worm 342 to rotate. This helps to reduce the safety problems caused by the unstable lifting and lowering of the handrail 20 due to external forces or the unstable position after stopping.

[0083] Reference Figure 5 In some embodiments, a bracket 110 is provided inside the lower cover 90, and the worm gear 342 is disposed on the bracket 110.

[0084] In some embodiments, the worm gear 341 is coaxially arranged with the third transmission member 333.

[0085] In some embodiments, the rotation axis of the worm gear 341 is perpendicular to the extension direction of the guide rod 10.

[0086] Reference Figure 4In some embodiments, the handrail device 100 further includes a speed switch 40, which is signal-connected to the drive mechanism 30 and configured to indirectly control the lifting speed of the handrail 20 by controlling the drive mechanism 30.

[0087] It is understandable that controlling the speed switch 40 can control the driving speed of the drive mechanism 30, thereby indirectly controlling the lifting speed of the armrest 20. This allows drivers and passengers to switch the lifting speed of the armrest 20 at any time according to their needs, which helps drivers and passengers with different physical conditions to switch the lifting speed of the armrest 20 according to their own needs.

[0088] In some embodiments, the first drive unit 31 is a motor, and the speed switch 40 changes the power supply voltage and / or current of the first drive unit 31 by changing the voltage and / or current of the power supply, thereby controlling the rotational speed of the first drive unit 31, thereby controlling the driving speed of the drive mechanism 30, and subsequently controlling the lifting speed of the handrail 20.

[0089] In some embodiments, the handrail device 100 includes a control module (not shown in the figure), a speed switch 40 and a first drive member 31 are both signal connected to the control module, the speed switch 40 has multiple speed levels, when the speed switch 40 is toggled or pressed to the corresponding level, the control module controls the first drive member 31 to output the corresponding rotation speed according to the level signal of the speed switch 40, thereby controlling the lifting speed of the handrail 20.

[0090] The specific signal connection method between the speed switch 40 and the drive mechanism 30 and the control module can adopt existing technology, which will not be elaborated here.

[0091] In some embodiments, the gear shift switch 40 is disposed on the handrail 20, so that the gear shift switch 40 can be raised and lowered synchronously with the handrail 20, so as to facilitate the operation of the gear shift switch 40 by the driver and passengers.

[0092] Reference Figure 5 In some embodiments, the drive mechanism 30 further includes a transmission 35, the first drive member 31 is connected to the second transmission assembly 34 via the transmission 35, and the speed switch 40 is configured to indirectly control the lifting speed of the handrail 20 by controlling the output speed of the transmission 35.

[0093] It is understood that when the output speed of the first drive component 31 is constant, the speed switch 40 can control the output speed of the second transmission component 34 by controlling the output speed of the transmission 35, thereby controlling the output speed of the first transmission component 33, and then controlling the lifting speed of the handrail 20.

[0094] The speed switch 40 and the gearbox 35 can be connected to the same control module. The speed switch 40 has multiple speed positions. When the speed switch 40 is moved to the corresponding position, the control module controls the gearbox 35 to output the corresponding speed according to the position of the speed switch 40, thereby controlling the lifting speed of the handrail 20.

[0095] The signal connection method between the speed switch 40 and the gearbox 35 and the control module can adopt existing technology, which will not be elaborated here.

[0096] Reference Figures 4 to 8 In some embodiments, the transmission 35 includes multiple gear sets with different gear ratios. Each gear set includes a driving gear 351 and a driven gear 352 that mesh with each other. The driving gear 351 is connected to the first driving member 31, and the driven gear 352 is connected to the second transmission assembly 34.

[0097] It is understandable that the transmission 35 outputs different speeds through gear sets composed of different gear ratios, thereby controlling the output speed of the second transmission component 34, which in turn controls the output speed of the first transmission component 33, and subsequently controls the lifting speed of the armrest 20.

[0098] For example, the transmission 35 is provided with three sets of gears, and the transmission 35 has three output speeds: medium, low, and high. Among them, Figure 6 The 35-speed transmission outputs at low speed. Figure 7 The 35-speed transmission provides a medium output speed. Figure 8 The intermediate transmission has a speed of 35, which is high speed.

[0099] Reference Figures 5 to 8 In some embodiments, the driving gears 351 of multiple gear sets are all disposed on the first mounting shaft 353. The handrail device 100 also includes a second driving member 32. One end of the first mounting shaft 353 is connected to the first driving member 31, and the other end is connected to the second driving member 32. The second driving member 32 is configured to drive the first mounting shaft 353 to move along its axial direction so that the driving gear 351 and the corresponding driven gear 352 of one of the multiple gear sets mesh. The speed switch 40 is signal connected to the second driving member 32 and is configured to control the driving direction of the second driving member 32.

[0100] It is understandable that the driving gear 351 in different gear sets is coaxially arranged.

[0101] It can be understood that the gear switch 40 controls the driving direction of the second drive member 32, thereby controlling the movement of the first mounting shaft 353 to engage one of the multiple gear sets, thus controlling the output gear ratio and consequently the output speed of the transmission 35. The gear switch 40 can be signal-connected to the second drive member 32 via a control module. The control module, based on the gear position of the gear switch 40 and the current output gear ratio of the transmission 35, controls the second drive member 32 to drive the first mounting shaft 353 axially, thereby engaging one of the multiple gear sets and changing the output speed of the transmission 35.

[0102] In some embodiments, the first mounting shaft 353 is keyed to the execution end of the first drive member 31.

[0103] In some embodiments, the second drive element 32 is mounted on the bracket 110.

[0104] In some embodiments, the driven gears 352 of the multiple gear sets are all disposed on the second mounting shaft 354. One end of the second mounting shaft 354 is rotatably disposed on the bracket 110, and the other end is rotatably disposed on the housing of the first drive member 31 to stabilize the position of the second mounting shaft 354. The second mounting shaft 354 is connected to the worm gear 342 and is coaxially disposed.

[0105] For example, such as Figures 6 to 8As shown, the first mounting shaft 353 and the second mounting shaft 354 are arranged in parallel. The rotation axis of the first mounting shaft 353 is parallel to the rotation axis of the worm gear 342. The rotation axis of the first mounting shaft 353, the rotation axis of the worm gear, and the extension direction of the guide rod 10 are perpendicular to each other. In the three gear sets, along the axial direction of the first mounting shaft 353 and away from the first driving member 31, the diameters of the three driving gears 351 increase sequentially. The three driving gears 351 are the first driving gear, the second driving gear, and the third driving gear, respectively. The diameters of the three driven gears 352 decrease sequentially. The three driven gears 352 are the first driven gear, the second driven gear, and the third driven gear, respectively. The second driving member 32 drives the first mounting shaft 353 to move laterally, thereby moving the positions of the three driving gears 351 so that one of the three driving gears 351 meshes with the corresponding driven gear 352. Specifically, the gear shift switch 40 has three gears: high, medium, and low. If the armrest 20 needs to be raised or lowered at a medium speed, the driver or passenger can switch the gear shift switch 40 to the medium speed position, which will control the second drive component 32 to drive the first mounting shaft 353 to move, so that the second drive gear and the second driven gear mesh. If the armrest 20 needs to be raised or lowered at a low speed, the driver or passenger can switch the gear shift switch 40 to the low speed position, which will control the second drive component 32 to drive the first mounting shaft 353 to move, so that the first drive gear and the first driven gear mesh. If the armrest 20 needs to be raised or lowered at a high speed, the driver or passenger can switch the gear shift switch 40 to the high speed position, which will control the second drive component 32 to drive the first mounting shaft 353 to move, so that the third drive gear and the third driven gear mesh.

[0106] In some embodiments, the handrail device 100 further includes a direction switch 50, which is signal-connected to the drive mechanism 30. The direction switch 50 is configured to indirectly control the lifting and lowering of the handrail 20 by controlling the movement direction of the drive mechanism 30.

[0107] It can be understood that the direction switch 50 controls the rise or fall of the handrail 20 by controlling the driving direction of the drive mechanism 30, thereby changing the movement direction of the handrail 20.

[0108] Specifically, the direction switch 50 can be signal-connected to the first drive unit 31.

[0109] In other embodiments, the direction switch 50 is a relay. When the relay is not in operation, the first driving member 31 rotates forward, and the handrail 20 rises. When the relay is in operation, the first driving member 31 rotates in reverse, and the handrail 20 falls. The specific structure of the relay can adopt existing technology, which will not be described in detail here.

[0110] In some other embodiments, the direction switch 50 is a double-pole double-throw switch. When the driver or passenger moves or presses the direction switch 50, the positive and negative power input of the first drive member 31 can be changed to realize the forward and reverse control of the first drive member 31. When one end of the switch is connected to the positive terminal and the other end is connected to the negative terminal, the first drive member 31 rotates forward and the handrail 20 rises. Conversely, the first drive member 31 rotates in reverse and the handrail 20 falls.

[0111] In some embodiments, the direction switch 50 is disposed on the armrest 20, so that the direction switch 50 can be raised and lowered synchronously with the armrest 20, so that the driver and passengers can control the direction switch 50.

[0112] In some embodiments, the handrail device 100 further includes a first limit switch 60, which is disposed on the guide rod 10. The first limit switch 60 is signal-connected to the drive mechanism 30 and configured to control the drive mechanism 30 to stop when the handrail 20 rises to the limit position.

[0113] It is understandable that the first limit switch 60 can stop the drive mechanism 30, thereby stopping the handrail 20 from rising.

[0114] In this embodiment of the application, the first limit switch 60 helps to reduce the risk of damage to the handrail device 100 caused by the handrail 20 rising beyond its travel range.

[0115] In the embodiment where the first driving component 31 is a motor, the first limit switch 60 is connected to the motor signal. When the handrail 20 rises to the limit position, it touches or presses the first limit switch 60, which controls the circuit where the motor is located to disconnect, thereby controlling the drive mechanism 30 to stop.

[0116] Of course, the first limit switch 60 can also be connected to the first drive unit 31 via the control module. When the handrail 20 rises to the limit position, it touches or presses the first limit switch 60. When the control module receives the signal that the first limit switch 60 has been touched or pressed, it controls the first drive unit 31 to stop, thereby controlling the drive mechanism 30 to stop.

[0117] In some embodiments, the handrail device 100 further includes a second limit switch 70, which is disposed on the guide rod 10. The second limit switch 70 is signal-connected to the drive mechanism 30 and configured to control the drive mechanism 30 to stop when the handrail 20 descends to its limit position.

[0118] It is understandable that the second limit switch 70 can stop the drive mechanism 30, thereby stopping the handrail 20 from descending.

[0119] In this embodiment of the application, a second limit switch 70 is provided, which helps to reduce the risk of damage to the handrail device 100 caused by the handrail 20 falling beyond its travel range.

[0120] In the embodiment where the first driving component 31 is a motor, the second limit switch 70 is connected to the motor signal. When the handrail 20 descends to the limit position, it touches or presses the second limit switch 70, which controls the circuit where the motor is located to disconnect, thereby controlling the drive mechanism 30 to stop.

[0121] Of course, the second limit switch 70 can also be connected to the first drive unit 31 via the control module. When the handrail 20 descends to the limit position, it touches or presses the second limit switch 70. When the control module receives the signal that the second limit switch 70 has been touched or pressed, it controls the first drive unit 31 to stop, thereby controlling the drive mechanism 30 to stop.

[0122] In some embodiments, a first limit switch 60 is disposed on the side of the upper cover 80 facing the lower cover 90.

[0123] In some embodiments, the second limit switch 70 is disposed on the side of the lower cover 90 facing the upper cover 80.

[0124] Reference Figure 9 , Figure 10 and Figure 11 According to a second aspect of this application, an assistive device 1000 is provided, including the handrail device 100 of the first aspect. Since the assistive device 1000 includes the handrail device 100, the assistive device 1000 has all the beneficial effects of the handrail device 100, which will not be elaborated here.

[0125] In some embodiments, the handrail device 100 further includes a pedal device 200 and a controller 300.

[0126] The pedal device 200 includes a base 210 and a pedal 220. The pedal 220 is vertically and vertically mounted on the base 210. Both the handrail device 100 and the pedal device 200 are signal-connected to the controller 300, which is configured to control the handrail 20 and the pedal 220 to rise and fall synchronously.

[0127] It is understandable that the controller 300 can synchronize the handrail 20 and the pedal 220, so that the handrail 20 rises synchronously when the pedal 220 rises, and the handrail 20 descends synchronously when the pedal 220 descends. This design helps drivers and passengers maintain their balance when getting on and off the vehicle, reducing the risk of falls.

[0128] Specifically, the pedal device 200 also includes a third driving member, which drives the pedal 220 to rise and fall. Both the third driving member and the first driving member 31 are connected to the controller 300 via signals. The controller 300 controls the third driving member and the first driving member 31 to output synchronously, thereby indirectly driving the handrail 20 and the pedal 220 to rise or fall synchronously.

[0129] According to a third aspect of this application, a vehicle is provided, including a handrail device 100 provided in any embodiment of the first aspect or an assistive device provided in any embodiment of the second aspect.

[0130] Since the vehicle includes a handrail device 100 or a power assist device 1000, the vehicle has all the beneficial effects of the handrail device 100 or the power assist device 1000, which will not be elaborated here.

[0131] The vehicle may include, but is not limited to, gasoline-powered vehicles, plug-in hybrid electric vehicles, or new energy vehicles, and this application does not make any specific limitation in this regard.
