DETAILED DESCRIPTION

[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0034] like Figure 1-5 As shown, the electric pedal with a locking function of an embodiment of the utility model comprises a pedal 1, a telescopic mechanism 2 and a locking device 3. The pedal 1 is suitable for being installed on a vehicle. The telescopic mechanism 2 is installed on the vehicle and connected to the pedal 1. The telescopic mechanism 2 is used to drive the pedal 1 to move between a first position (not shown) and a second position (not shown) relative to the vehicle. When the pedal 1 is in the first position, the pedal 1 is in an extended state, so that it is convenient to step on when getting on and off the vehicle. When the pedal 1 is in the second position, the pedal 1 is in a retracted state, so that when the vehicle is driving, the pedal 1 is not easy to rub against surrounding objects. There is an angle between the first position and the second position, and the angle is greater than 0 degrees. The locking device 3 is arranged on the telescopic mechanism 2, and the locking device 3 is used to lock the pedal 1 at the first position, the second position and any position between the first position and the second position.

[0035] In the electric pedal with a locking function of the embodiment of the utility model, the telescopic mechanism 2 drives the pedal 1 to move between the first position and the second position, so that the user can step on the pedal 1 in different states. The setting of the locking device 3 can not only ensure that the pedal 1 remains stable in any position, but also allows the force applied to the pedal 1 when being stepped on to act on the locking device 3, thereby improving the bearing capacity of the pedal 1 and protecting the parts inside the telescopic mechanism 2 from being easily damaged.

[0036] In some embodiments, the locking device 3 includes a connecting plate 31, a stopper 32, a toggle member 33, and a driving member 34. The connecting plate 31 is provided on the telescopic mechanism 2, and one end of the driving shaft of the telescopic mechanism 2 passes through the connecting plate 31 along the thickness direction of the connecting plate 31. Specifically, the driving shaft of the telescopic mechanism 2 controls the extension and retraction of the pedal 1 by rotating around its own extension direction. A through hole 311 is provided in the middle position of the connecting plate 31, and the through hole 311 penetrates the connecting plate 31 along the thickness direction of the connecting plate 31, and one end of the driving shaft of the telescopic mechanism 2 can pass through the through hole 311.

[0037] The stopper 32 is located on the side of the connecting plate 31 away from the telescopic mechanism 2 and connected to one end of the driving shaft. The stopper 32 can rotate with the driving shaft of the telescopic mechanism 2 relative to the connecting plate 31, and a notch 321 is provided on the outer peripheral surface of the stopper 32. Specifically, a long hole 322 is provided in the middle of the stopper 32, and the cross section of one end of the driving shaft of the telescopic mechanism 2 is in the shape of a long strip, and one end of the driving shaft is adapted to the long hole 322, so that the stopper 32 and the driving shaft of the telescopic mechanism 2 are matched stably, and the stopper 32 is not easy to have relative movement with the driving shaft of the telescopic mechanism 2.

[0038] The toggle member 33 is disposed on the side of the connecting plate 31 away from the telescopic mechanism 2. The toggle member 33 is rotatable relative to the connecting plate 31, and at least a portion of the toggle member 33 is engaged with the notch 321. The driving member 34 is connected to the toggle member 33, and the driving member 34 is used to drive the toggle member 33 to rotate so that at least a portion of the toggle member 33 is engaged with the notch 321 or is disengaged from the notch 321. The driving member 34 is a motor.

[0039] Specifically, when the driving member 34 drives at least part of the toggle member 33 to cooperate with the notch 321, the toggle member 33 can limit the rotation of the limit member 32 relative to the connecting plate 31, thereby limiting the rotation of the driving shaft of the telescopic mechanism 2, so that the pedal 1 remains stable at a certain position. When the driving member 34 drives at least part of the toggle member 33 to disengage from the notch 321, the toggle member 33 does not limit the limit member 32, and the limit member 32 can rotate with the driving shaft of the telescopic mechanism 2, so that the pedal 1 can move between the first position and the second position. Therefore, the driving member 34 drives the toggle member 33 to limit the pedal 1, which not only makes the operation method simple and the locking effect good, but also makes the force applied to the pedal 1 when it is stepped on act on the toggle member 33, so as to prevent the force applied to the pedal 1 from being transmitted to the parts inside the telescopic mechanism 2, and protect the parts inside the telescopic mechanism 2 from being damaged. In addition, the locking device 3 has a simple structure and is easy to assemble.

[0040] In some embodiments, there are multiple recesses 321, and the multiple recesses 321 are arranged at intervals around the circumference of the outer circumference of the stopper 32. Specifically, the outer circumference of the stopper 32 is cylindrical, and the multiple recesses 321 are evenly arranged around the outer circumference of the stopper 32. At least part of the toggle member 33 can cooperate with different recesses 321, so that the locking device 3 has multiple locking positions, so that the pedal 1 has different position states.

[0041] In some embodiments, the cross-sectional area of ​​the notch 321 gradually decreases from one end of the notch 321 away from the center of the stopper 32 to the other end of the notch 321 adjacent to the center of the stopper 32 , making it easier to insert at least part of the toggle member 33 into the notch 321 .

[0042] In some embodiments, the toggle member 33 includes a body 331 and an insert block 332 . One end of the body 331 is rotatably connected to the side of the connecting plate 31 away from the telescopic mechanism 2 . The insert block 332 is disposed at the other end of the body 331 and cooperates with the notch 321 .

[0043] Specifically, the body 331 is located above the stopper 32, and the insert block 332 is located on the side of the body 331 adjacent to the stopper 32. The driving member 34 is connected to one end of the body 331, and drives one end of the body 331 to rotate, thereby driving the other end of the body 331 to rotate, thereby driving the insert block 332 to perform a circular motion with one end of the body 331 as the center and the length direction of the body 331 as the radius. Preferably, the rotation angle of the insert block 332 is 90 degrees.

[0044] In some embodiments, the cross-sectional area of ​​the plug block 332 gradually decreases from one end of the plug block 332 adjacent to the body 331 to the end of the plug block 332 away from the body 331, so that the plug block 332 is more easily inserted into the recess 321 and matched with the recess 321. The plug block 332 is adapted to the recess 321, so that the plug block 332 is stably installed in the recess 321 and is not easy to be separated from the recess 321.

[0045] In some embodiments, the side of the body 331 adjacent to the stopper 32 has a recess 3311, and the cross-sectional area of ​​one end of the body 331 is larger than the cross-sectional area of ​​the other end of the body 331. Specifically, the arrangement of the recess 3311 makes it difficult for the side of the body 331 adjacent to the stopper 32 to contact the outer peripheral surface of the stopper 32 when the insert 332 is matched with the notch 321, thereby reducing friction.

[0046] In some embodiments, the locking device 3 further includes a friction reducing ring 35 and a fixed cover 36. The friction reducing ring 35 is sleeved on one end of the driving shaft, and the friction reducing ring 35 is located between the limiter 32 and the connecting plate 31 to reduce the friction between the limiter 32 and the connecting plate 31, thereby extending the service life of the locking device 3. The fixed cover 36 is arranged on the side of the connecting plate 31 away from the telescopic mechanism 2, the limiter 32 and the toggle member 33 are located between the fixed cover 36 and the connecting plate 31, and at least part of the driving member 34 passes through the fixed cover 36 and is connected to the toggle member 33.

[0047] Specifically, the fixed cover 36 is fixedly connected to the connecting plate 31, and an installation space (not shown) is formed between the fixed cover 36 and the connecting plate 31. The limiting member 32 and the toggle member 33 are located in the installation space, so that the limiting member 32 and the toggle member 33 are installed firmly, thereby improving the integrity and fit of the locking device 3 and ensuring that the various components of the locking device 3 are closely matched.

[0048] The structure of the locking device 3 is not limited to the above description. In some embodiments, the locking device 3 includes a limit plate 41, an electromagnet 42, and an electromagnetic fixing cover 43. One end of the limit plate 41 is connected to one end of the driving shaft of the telescopic mechanism 2. Specifically, a flat mouth 411 is provided at one end of the limit plate 41, and the flat mouth 411 cooperates with one end of the driving shaft of the telescopic mechanism 2, so that the limit plate 41 is firmly connected to one end of the driving shaft of the telescopic mechanism 2, and the limit plate 41 can rotate with the driving shaft of the telescopic mechanism 2.

[0049] At least part of the electromagnet 42 cooperates with the other end of the limit plate 41. When the electromagnet 42 is powered on, at least part of the electromagnet 42 is connected to the other end of the limit plate 41, and the limit plate 41 limits the rotation of the driving shaft of the telescopic mechanism 2, thereby limiting the pedal 1. When the electromagnet 42 is powered off, at least part of the electromagnet 42 is disconnected from the other end of the limit plate 41, and the driving shaft of the telescopic mechanism 2 can rotate, so that the pedal 1 can rotate with the driving shaft of the telescopic mechanism 2. Specifically, the other end of the limit plate 41 has a through hole 412. When the electromagnet 42 is powered on, at least part of the electromagnet 42 cooperates with the through hole 412. When the electromagnet 42 is powered off, at least part of the electromagnet 42 is separated from the through hole 412.

[0050] The electromagnetic fixing cover 43 is arranged on the telescopic mechanism 2, the limiting plate 41 is located between the electromagnetic fixing cover 43 and the telescopic mechanism 2, the electromagnet 42 is installed on the electromagnetic fixing cover 43, and at least part of the electromagnet 42 cooperates with the limiting plate 41 through the electromagnetic fixing cover 43. The arrangement of the electromagnetic fixing cover 43 improves the integrity and coordination of the locking device 3, and ensures that the various components of the locking device 3 are tightly coordinated.

[0051] In some embodiments, the locking device 3 is an electromagnetic brake. Specifically, the electromagnetic brake is provided on the telescopic mechanism 2 and is connected to the driving shaft of the telescopic mechanism 2. When the electromagnetic brake is powered on, the brake is opened to lock the telescopic mechanism 2 so that the pedal 1 remains stable. When the electromagnetic brake is powered off, the brake is closed, and the telescopic mechanism 2 can drive the pedal 1 to move.

[0052] In some embodiments, the telescopic mechanism 2 includes a telescopic device 21 and a motor 22, and the motor 22 is connected to the telescopic device 21. The locking device 3 is disposed between the telescopic device 21 and the motor 22, and the locking device 3 is connected to the telescopic device 21 and the motor 22, and the motor 22 locks the telescopic device 21 by driving the locking device 3 to rotate.

[0053] Specifically, the locking device 3 is a brake member, which is arranged between the telescopic device 21 and the motor 22. A connecting shaft 51 is arranged between the brake member and the motor 22, and the motor 22 is connected to the brake member through the connecting shaft 51. The motor 22 drives the connecting shaft 51 to rotate forward and reversely to open the brake member. At this time, the brake will not lock the telescopic device 21. Then the motor 22 drives the telescopic device 21 to adjust the position of the pedal 1. When the position of the pedal 1 is determined, the motor 22 drives the driving shaft of the telescopic device 21 to reverse. At this time, the brake works to lock the telescopic mechanism 2, so that the pedal 1 remains stable.

[0054] Therefore, the locking device 3 of the electric pedal with locking function in the embodiment of the utility model has multiple implementation forms, and each locking device 3 is easy to operate when used, thereby improving the practicality and applicability of the electric pedal 1.
