[0038] The following combination Figures 1-7Describe in detail the electric step 100 according to an embodiment of the present invention and a vehicle having the same.
[0039] Refer to Figures 1-3 As shown, the electric step 100 according to an embodiment of the present invention includes: a fixing assembly 20 and a step assembly 10. The fixing assembly 20 includes a first side plate 201. The step assembly 10 includes: a pedal 1, a driver 2, a driving shaft 3, a main shaft limiting member 4, and a first limiting block 5. The driver 2 is fixedly connected to the first side plate 201. The driving shaft 3 is rotatably disposed through the first side plate 201. One end of the driving shaft 3 is in transmission connection with the driver 2, and the other end of the driving shaft 3 is fixedly connected to the pedal 1. The main shaft limiting member 4 is fixedly connected to the driving shaft 3, and the first limiting block 5 is fixedly connected to the first side plate 201. Wherein, the driver 2 drives the pedal 1 to rotate forward and backward through the driving shaft 3. When the pedal 1 rotates forward to the open position, the first limiting block 5 stops the main shaft limiting member 4 in the forward rotation direction. When the pedal 1 rotates backward to the closed position, the first limiting block 5 stops the main shaft limiting member 4 in the reverse rotation direction.
[0040] It can be understood that the electric step 100 can be used for a vehicle with a relatively high chassis height. When a passenger gets on or off the vehicle, the pedal 1 of the electric step 100 can be rotated to the open position, and the pedal 1 can form a step between the ground and the chassis to facilitate the passenger to get on or off the vehicle.
[0041] The driver 2 is in transmission connection with the driving shaft 3. The driver 2 can drive the driving shaft 3 to rotate. The rotation of the driving shaft 3 can drive the pedal 1 and the main shaft limiting member 4 connected to the driving shaft 3 to rotate synchronously. Specifically, when the driver 2 drives the driving shaft 3 to rotate forward, the rotation of the driving shaft 3 can drive the pedal 1 and the main shaft limiting member 4 to rotate forward synchronously. When the pedal 1 rotates forward to the open position, the first limiting block 5 stops the main shaft limiting member 4 in the forward rotation direction. The first limiting block 5 can prevent the main shaft limiting member 4 from continuing to rotate forward, thereby restricting the forward rotation of the driving shaft 3, restricting the forward rotation of the pedal 1, and keeping the pedal 1 in the Figure 2 horizontal state as shown. The pedal 1 can form a step between the chassis of the vehicle and the ground to facilitate the passenger to step on the pedal 1 to get on or off the vehicle. In addition, when the passenger steps on the pedal 1, through the stop of the main shaft limiting member 4 by the first limiting block 5, the torque applied by the passenger's own weight to the pedal 1 can be borne to prevent the pedal 1 from rotating accidentally, which is beneficial to ensuring the safety of the passenger. Moreover, the driver 2 does not need to apply a torque to overcome the rotation of the driving shaft 3, which can avoid the driver 2 from being damaged due to overload.
[0042] When the driver 2 drives the driving shaft 3 to rotate backward, the rotation of the driving shaft 3 can drive the pedal 1 and the main shaft limiting member 4 to rotate backward synchronously. When the pedal 1 rotates backward to the open position, the first limiting block 5 stops the main shaft limiting member 4 in the reverse rotation direction. The first limiting block 5 can prevent the main shaft limiting member 4 from continuing to rotate backward, thereby restricting the backward rotation of the driving shaft 3, restricting the backward rotation of the pedal 1, and keeping the pedal 1 in theFigure 3 In the vertical state shown, the pedal 1 is stored to reduce the protruding part of the vehicle, which is beneficial to improving the passing performance of the vehicle for normal driving. Among them, the forward rotation direction can be Figure 2 and Figure 3 the a direction in Figure 2 and Figure 3 the b direction in
[0043] Compared with the method in the related art where the driver drives the pedal to rotate through the link assembly, in this embodiment, the driver 2 is used to drive the rotation of the main shaft 3, and the pedal 1 is directly driven to rotate through the main shaft 3. The electric tread 100 has a simple structure, which is beneficial to reducing the design difficulty of the electric tread 100. Moreover, the main shaft 3 occupies less space than the link assembly, facilitating the arrangement of the electric tread 100 on the vehicle body.
[0044] According to the electric tread 100 of the embodiment of the present invention, the driver 2 can directly drive the pedal 1 to rotate through the main shaft 3 to open and close the pedal 1. The electric tread 100 of this embodiment has a relatively simple structure and small overall occupied space, and has a small requirement for the layout space of the vehicle body, facilitating the layout of the electric tread 100 on the vehicle body.
[0045] In some embodiments of the present invention, referring to Figure 1 and Figure 4 as shown, the first limiting block 5 has a first front limiting surface and a first rear limiting surface arranged opposite to each other. The main shaft limiting member 4 includes: a first main shaft arm 41, a second main shaft arm 42, and a main shaft connecting sleeve 43. The main shaft connecting sleeve 43 is sleeved and fixed on the main shaft 3. Both the first main shaft arm 41 and the second main shaft arm 42 are fixedly connected to the main shaft connecting sleeve 43. The first main shaft arm 41 and the second main shaft arm 42 are relatively arranged in the radial direction of the main shaft 3. When the pedal 1 rotates forward to the open position, the first front limiting surface stops the first main shaft arm 41 in the forward rotation direction, and the first rear limiting surface stops the second main shaft arm 42 in the forward rotation direction. When the pedal 1 rotates reversely to the closed position, the first front limiting surface stops the first main shaft arm 41 in the reverse rotation direction, and the first rear limiting surface stops the second main shaft arm 42 in the reverse rotation direction. Among them, the first limiting surface can be the front side surface of the first limiting block 5, and the first rear limiting surface can be the rear side surface of the first limiting block 5.
[0046] It can be understood that the main shaft connecting sleeve 43 is sleeved and fixed on the main shaft 3, which can realize the fixed connection between the main shaft limiting member 4 and the main shaft 3. When the pedal 1 rotates forward to the open position, referring to Figure 2As shown, the first front limiting surface stops the first main shaft arm 41 in the forward rotation direction, and the first rear limiting surface stops the second main shaft arm 42 in the forward rotation direction. By using the first front limiting surface and the first rear limiting surface of the first limiting block 5 to stop the first main shaft arm 41 and the second main shaft arm 42 respectively, the stopping effect of the first limiting block 5 on the main shaft limiting member 4 can be improved, thereby reliably restricting the further forward rotation of the pedal 1. In addition, when the occupant steps on the pedal 1, through the stopping of the main shaft limiting member 4 by the first limiting block 5, the torque applied by the occupant's own weight to the pedal 1 can be borne to prevent the accidental rotation of the pedal 1, which is beneficial to ensuring the safety of the occupant. Moreover, the driver 2 does not need to apply a torque to overcome the rotation of the main shaft 3 to the driving shaft 3, which can avoid the overload and damage of the driver 2.
[0047] When the pedal 1 rotates in reverse to the closed position, refer to Figure 3 As shown, the first front limiting surface stops the first main shaft arm 41 in the reverse rotation direction, and the first rear limiting surface stops the second main shaft arm 42 in the reverse rotation direction. By using the first limiting surface and the first rear limiting surface of the first limiting block 5 to stop the first main shaft arm 41 and the second main shaft arm 42 respectively, the stopping effect of the first limiting block 5 on the main shaft limiting member 4 can be improved, thereby reliably restricting the further reverse rotation of the pedal 1.
[0048] In some embodiments of the present invention, refer to Figure 1 As shown, the fixing assembly 20 further includes: a second side plate 202, which is disposed opposite to the first side plate 201, and the pedal 1 is disposed between the first side plate 201 and the second side plate 202. The stepping assembly 10 further includes: a driven shaft 6, and the pedal 1 is rotatably connected to the second side plate 202 through the driven shaft 6. The second side plate 202 can support the other side of the pedal 1 away from the first side plate 201 through the driven shaft 6, which is beneficial to improving the stability of the pedal 1.
[0049] It can be understood that, refer to Figure 1 As shown, in the left-right direction of the electric step 100, the first side plate 201 and the second side plate 202 are respectively located on the left and right sides of the pedal 1. The first side plate 201 can support the left side of the pedal 1 through the driving shaft 3, and the second side plate 202 can support the right side of the pedal 1 through the driven shaft 6. When the occupant steps on the pedal 1, supporting the left and right sides of the pedal 1 can avoid local stress concentration on the pedal 1, which is beneficial to reducing the risk of local deformation of the pedal 1.
[0050] In some embodiments of the present invention, refer to Figure 1As shown, the step component 10 further includes: a slave shaft limiting member 7 and a second limiting block 8. The slave shaft limiting member 7 is fixedly connected to the driven shaft 6, and the second limiting block 8 is fixedly connected to the second side plate 202. When the pedal 1 rotates forward to the open position, the second limiting block 8 stops the slave shaft limiting member 7 in the forward rotation direction, thereby restricting the forward rotation of the slave shaft limiting member 7 to limit the forward rotation of the driven shaft 6, and further restricting the forward rotation of the pedal 1. When the pedal 1 rotates backward to the closed position, the second limiting block 8 stops the slave shaft limiting member 7 in the reverse rotation direction, thereby restricting the reverse rotation of the slave shaft limiting member 7 to limit the reverse rotation of the driven shaft 6, and further restricting the reverse rotation of the pedal 1.
[0051] Referring to Figure 1 and Figure 5 As shown, the second limiting block 8 has a second front limiting surface and a second rear limiting surface arranged opposite to each other. The slave shaft limiting member 7 includes a first slave shaft support arm 71, a second slave shaft support arm 72, and a slave shaft connecting sleeve 73. The slave shaft connecting sleeve 73 is sleeved and fixed on the driven shaft 6. Both the first slave shaft support arm 71 and the second slave shaft support arm 72 are fixedly connected to the slave shaft connecting sleeve 73. The first slave shaft support arm 71 and the second slave shaft support arm 72 are oppositely arranged in the radial direction of the driven shaft 6. When the pedal 1 rotates forward to the open position, the second front limiting surface stops the first slave shaft support arm 71 in the forward rotation direction, and the second rear limiting surface stops the second slave shaft support arm 72 in the forward rotation direction. When the pedal 1 rotates backward to the closed position, the second front limiting surface stops the first slave shaft support arm 71 in the reverse rotation direction, and the second rear limiting surface stops the second slave shaft support arm 72 in the reverse rotation direction. Among them, the second front limiting surface can be the front side surface of the second limiting block 8, and the second rear limiting surface can be the rear side surface of the second limiting block 8.
[0052] In some embodiments of the present invention, referring to Figure 1 As shown, the main shaft limiting member 4 and the slave shaft limiting member 7 are mirror images of each other, and the first limiting block 5 and the second limiting block 8 are mirror images of each other, which is beneficial to reducing the design and R & D cycle of the main shaft limiting member 4, the slave shaft limiting member 7, the first limiting block 5, and the second limiting block 8.
[0053] It can be understood that when designing the main shaft limiting member 4 and the slave shaft limiting member 7, only one of the main shaft limiting member 4 and the slave shaft limiting member 7 needs to be designed, and the other can be quickly generated through mirror operation, thereby saving the design and R & D cycle. When designing the first limiting block 5 and the second limiting block 8, only one of the first limiting block 5 and the second limiting block 8 needs to be designed, and the other can be quickly generated through mirror operation, thereby saving the design and R & D cycle.
[0054] In other embodiments of the utility model, the main shaft limiter 4 and the slave shaft limiter 7 have the same structure and are assembled in a mirror-symmetrical manner. The first limit block 5 and the second limit block 8 have the same structure and are assembled in a mirror-symmetrical manner. This can reduce the number of parts of the electric stepper 100 and help reduce the difficulty of designing and manufacturing the electric stepper 100.
[0055] In some embodiments of the present invention, referring to Figure 1 As shown, the fixing assembly 20 also includes: a connecting plate 203, which is connected between the first side plate 201 and the second side plate 202. The connecting plate 203 can support the first side plate 201 and the second side plate 202, which is beneficial to improving the structural strength of the electric step 10.
[0056] Reference Figure 1 and Figure 2 As shown, in the up and down directions, the fixing assembly 20 includes two spaced-apart connecting plates 203, and the two connecting plates 203 are connected between the first side plate 201 and the second side plate 202. The first side plate 201, the two connecting plates 203 and the second side plate 202 can form a rectangular frame structure, which is beneficial to further enhance the structural strength of the electric pedal 1.
[0057] In some embodiments of the utility model, the driver 2 includes: a housing, a motor and a reducer. The housing is fixedly connected to the first side plate 201, and the motor and the reducer are both fixedly connected to the housing. The motor is transmission-connected to the driving shaft 3 via the reducer. The motor can drive the driving shaft 3 to rotate via the reducer. The reducer is suitable for reducing the output speed of the motor and increasing the output torque to achieve the effect of reducing speed and increasing torque, so as to drive the driving shaft 3 to rotate.
[0058] It can be understood that the reducer can reduce the rotation speed of the driving shaft 3, thereby reducing the rotation speed of the main shaft limiter 4, the pedal 1, the driven shaft 6 and the slave shaft limiter 7, which is beneficial to the smooth rotation of the pedal 1, and when the first limit block 5 stops the main shaft limiter 4 and the second limit block 8 stops the slave shaft limiter 7, the rotation speeds of the main shaft limiter 4 and the slave shaft limiter 7 are relatively slow, which is beneficial to reducing the impact force exerted by the main shaft limiter 4 on the first limiter 5 and reducing the impact force exerted by the slave shaft limiter 7 on the second limiter 8, thereby reducing the risk of damage to the first limiter 5 and the second limiter 8.
[0059] In some embodiments of the present invention, referring to Figures 1-3 As shown, there are multiple step assemblies 10, and the multiple step assemblies 10 are arranged at intervals along the length direction of the first side plate 201. Figure 1 In the up and down directions, multiple step assemblies 10 are arranged at intervals. When the pedals 1 of the multiple step assemblies 10 are all in the open position, the multiple pedals 1 can form multiple steps in the height direction of the vehicle to facilitate passengers to get on and off the vehicle through the multiple pedals 1.
[0060] Referring to Figure 1 and Figure 2 As shown, the number of the step assemblies 10 is two, and the two step assemblies 10 are spaced apart in the vertical direction. The length of the tread 1 of the step assembly 10 located below can be greater than the length of the tread 1 of the step assembly 10 located above. When the treads 1 of the two step assemblies 10 are both in the open position, the two treads 1 can form a step in the front - rear direction, facilitating the boarding and alighting of the passengers.
[0061] In some embodiments of the present utility model, referring to Figure 1 As shown, the electric step 100 further includes: a controller 30, which is communicatively connected to the driver 2. The controller 30 can send control signals to the driver 2 to drive the main shaft 3 to rotate forward and backward. After receiving the control signals, the driver 2 can drive the main shaft 3 to rotate forward and backward, so that the tread 1 can be rotated forward to the open position or rotated backward to the closed position.
[0062] Specifically, when the controller 30 sends a control signal to the driver 2 to drive the main shaft 3 to rotate forward, the driver 2 drives the main shaft 3 to rotate forward. The forward rotation of the main shaft 3 drives the main shaft limiting member 4 and the tread 1 to rotate forward synchronously, realizing the downward flipping of the tread 1. When the first limit block 5 stops the main shaft limiting member 4 in the forward rotation direction, the tread 1 is fully opened, realizing the dual control of the controller 30 and the first limit block 5 for the tread 1 to extend in place. The passengers can board and alight through the opened tread 1.
[0063] When the controller 30 sends a control signal to the driver 2 to drive the main shaft 3 to rotate backward, the driver 2 drives the main shaft 3 to rotate backward. The backward rotation of the main shaft 3 drives the main shaft limiting member 4 and the tread 1 to rotate backward synchronously, realizing the upward flipping of the tread 1. When the first limit block 5 stops the main shaft limiting member 4 in the backward rotation direction, the tread 1 is fully closed, realizing the dual control of the controller 30 and the first limit block 5 for the tread 1 to retract in place, facilitating the normal driving of the vehicle.
[0064] Referring to Figure 1 As shown, the number of the step assemblies 10 is two, and the two drivers 2 in the two step assemblies 10 are both communicatively connected to a controller 30. The controller 30 can send control signals to the two drivers 2 synchronously to drive the main shaft 3 to rotate forward and backward, so as to realize the synchronous opening and synchronous closing of the two treads 1 of the two step assemblies 10.
[0065] In some embodiments, the controller 30 can detect the state of the vehicle door. When the vehicle door is opened, the controller 30 can send a control signal to the driver 2 to drive the main shaft 3 to rotate forward. After receiving the control signal, the driver 2 can drive the main shaft 3 to rotate forward. The main shaft 3 can drive the pedal 1 to rotate forward to the open position, so that people can step on the pedal 1 to enter the vehicle. When the vehicle door is closed, the controller 30 can send a control signal to the driver 2 to drive the main shaft 3 to rotate reversely. After receiving the control signal, the driver 2 can drive the main shaft 3 to rotate reversely. The reverse rotation of the main shaft 3 can drive the pedal 1 to rotate reversely to the closed position, realizing the storage of the pedal 1, avoiding the pedal 1 protruding from the vehicle, and being beneficial to improving the passing performance of the vehicle.
[0066] In other embodiments, the controller 30 can be communicatively connected to the smart key. The occupant can send a signal to the controller 30 through the smart key to open the pedal 1. After receiving the signal, the controller 30 can send a control signal to the driver 2 to drive the main shaft 3 to rotate forward. After receiving the control signal, the driver 2 can drive the main shaft 3 to rotate forward. The main shaft 3 can drive the pedal 1 to rotate forward to the open position, so that people can step on the pedal 1 to enter the vehicle. The occupant can send a signal to the controller 30 through the smart key to close the pedal 1. After receiving the signal, the controller 30 can send a control signal to the driver 2 to drive the main shaft 3 to rotate reversely. After receiving the control signal, the driver 2 can drive the main shaft 3 to rotate reversely. The reverse rotation of the main shaft 3 can drive the pedal 1 to rotate reversely to the closed position, realizing the storage of the pedal 1, avoiding the pedal 1 protruding from the vehicle, and being beneficial to improving the passing performance of the vehicle.
[0067] In some embodiments of the present utility model, both the main shaft 3 and the driven shaft 6 can be rigidly connected to the pedal 1 through pins. The first side plate 201 can support the pedal 1 through the main shaft 3, and the second side plate 202 can support the pedal 1 through the driven shaft 6. The vehicle body can have a connecting groove, and the first side plate 201 and the driver 2 can be connected in the connecting groove. The appearance of the driver 2 is not visible, and a hidden flip electric step 100 can be formed.
[0068] In some embodiments of the present utility model, when the pedal 1 is opened, refer to Figure 2 As shown, the pedal 1 is initially in the closed position and is in a vertical state. The driver 2 can drive the main shaft 3 to rotate forward. The main shaft 3 can drive the pedal 1 to flip downward.
