When the parking mechanism of the vehicle is normal, the locking mechanism 130 is not needed to additionally lock the brake pedal 120, the driving member 132 can overcome the restoring force of the restoring member 133 and output the driving force outwards, and the driving member 132 can further drive the locking member 131 to be away from the locking position, so that the locking member 131 cannot limit the rotation of the brake pedal 120, and the brake pedal 120 can be stepped on without limitation.
When the parking mechanism of the vehicle fails, the driving member 132 can be stopped at this time, the driving member 132 does not output driving force outwards any more, the locking member 131 moves to the locking position under the action of the restoring force of the restoring member 133, and thus the locking member 131 can limit the rotation of the brake pedal 120, the brake pedal 120 is fixed at a position and does not rotate any more, and no matter whether the vehicle has electricity or not, the locking member 131 can move to the locking position under the action of the restoring member 133 to complete the limit of the brake pedal 120.
For example, when the parking mechanism of the vehicle fails, the brake pedal 120 may be depressed first to bring the vehicle into a braking state, and then the driving member 132 is stopped, and the driving member 132 no longer outputs driving force, at this time, the locking member 131 may be moved to the locking position by the restoring member 133, and the locking member 131 will restrict the rotation of the brake pedal 120, and the brake pedal 120 is maintained in a braking state.
According to the brake pedal assembly 100 of the embodiment of the present application, by providing the locking mechanism 130, when the parking mechanism of the vehicle fails, the brake pedal 120 can be depressed first, so that the vehicle is in a braking state, then the driving member 132 stops working, the driving member 132 no longer outputs driving force outwards, at this time, the locking member 131 can move to the locking position under the action of the resetting member 133, the locking member 131 will limit the rotation of the brake pedal 120, and the brake pedal 120 is kept in a braking state.

It should be noted that the locking member 131 is only slidable but not rotatable about its own axis, whereby the locking member 131 can be moved to the locking position, but upon engagement with the limit gear 134, the locking member 131 is not rotatable, thereby restricting the rotation of the brake pedal 120 so that the brake pedal 120 is maintained in the braking state.
Specifically, the mounting base 135 includes a bottom plate 135a and a first sleeve 135b, the bottom plate 135a is fixed on the base 110, one end of the first sleeve 135b is fixedly connected to the bottom plate 135a, the other end of the first sleeve 135b extends toward a direction approaching the limit gear 134, the locking member 131 is slidably disposed on the first sleeve 135b, and an axis of the first sleeve 135b may be orthogonal to the bottom plate 135a, so that the locking member 131 may move along an axis of the first sleeve 135 b.

Accordingly, one end of the restoring member 133 is fixed, and the restoring member 133 can always apply a restoring force to the locking member 131 to move toward the locking position. The restoring member 133 may be a restoring spring, and since the restoring member 133 is sleeved on the outer side of the first sleeve 135b, the restoring member 133 is more stable in the process of shrinkage and stretching.
Further, a stopper for limiting the rotation of the locker 131 is provided between the first sleeve 135b and the locker 131, and specifically, the stopper includes a stopper protrusion 136a and a stopper groove 136b engaged with each other, the stopper protrusion 136a extends in an axial direction of the first sleeve 135b, one of the stopper protrusion 136a and the stopper groove 136b is provided at an outer sidewall of the first sleeve 135b, and the other of the stopper protrusion 136a and the stopper groove 136b is provided at the locker 131. Thus, the locking member 131 can only slide along the axial direction of the first sleeve 135b, but cannot rotate relative to itself, and it should be noted that the locking member 131 may be sleeved on the outer side wall of the first sleeve 135 b.
In some embodiments of the present application, the mounting base 135 further includes a second sleeve 135c, the second sleeve 135c being disposed on the bottom plate 135a and located outside the first sleeve 135b, optionally, the axis of the second sleeve 135c coincides with the axis of the first sleeve 135b, and the second sleeve 135c, the first sleeve 135b and the bottom plate 135a define the positioning slot 101 for receiving the restoring member 133, thereby facilitating the mounting of the restoring member 133 and the positioning of the restoring member 133.
In some embodiments of the application, the driver 132 is configured as an electromagnet, and the outer periphery of the base plate 135a radially extends beyond the second sleeve 135c to define the mounting slot 102 that receives the electromagnet. Therefore, the electromagnet is fixed more conveniently, and the installation stability of the electromagnet is improved.
When the electromagnet is powered on, the restoring force of the restoring member 133 can be overcome, the locking member 131 is adsorbed, so that the locking member 131 is far away from the locking position, after the electromagnet is powered off, the restoring member 133 drives the locking member 131 to move to the locking position, so that the locking member 131 locks the limiting gear 134, the limiting gear 134 is limited to rotate, and the brake pedal 120 linked with the limiting gear 134 cannot rotate.
In some embodiments of the present application, the locking mechanism 130 further includes a rotating shaft 137, the rotating shaft 137 is fixed on the base 110, and the rotating shaft 137 passes through the limiting gear 134, the locking member 131 and the first sleeve 135b, and the limiting gear 134 is rotatable relative to the rotating shaft 137. It will be appreciated that the shaft 137 may be formed by a shank of a bolt having a head that abuts one end of the base 110, the free end of the shank passing through the base 110 and threadedly engaging a nut provided at the other end of the base 110.
