Description

Technical Field

[0001] The utility model relates to the technical field of electric pedals, in particular to a spring balance structure of a flip bracket assembly. Background Art

[0002] The car pedals are set on both sides of the door to facilitate the driver and passengers to get on and off the car, especially the elderly and children. Compared with the traditional fixed pedals, the electric pedals are automatically retractable pedals. When needed, the pedals extend to the side of the door sill; when not in use, the pedals are retracted to the bottom of the car. The electric pedals can make the overall vehicle model more beautiful and coordinated, without increasing the width of the vehicle or reducing the vehicle's passability.

[0003] The electric pedal flip bracket assemblies currently on the market do not have springs to balance gravity, and all use high-torque motors to drive the pedal bracket assemblies to flip. At the same time, high-cost peripheral accessories such as high-strength worm gears, gears, large-diameter cables, and high-power electronic components are required, resulting in high power consumption, high cost, and other problems. After the pedal is retracted, the self-locking mechanisms such as gears and worm gears are used to lock the flip bracket assembly on one side, thereby locking the pedal, and the pedal then maintains the flip bracket assembly on the other side to be retracted. However, after long-term driving vibration and impact, the locking mechanism of the flip bracket assembly will produce collisions, causing damage to the electric pedal locking mechanism, drive mechanism or flip mechanism. In addition, since the pedal is long and heavy, after long-term driving vibration, impact and gravity, the pedal is easily twisted and deformed, causing the flip mechanism end on the other side to fall and cause the pedal to collapse, resulting in shaking and abnormal noise during driving or reducing the vehicle's passability or even affecting driving safety.

[0004] Therefore, it is necessary to design a flip bracket structure with a balancing effect. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a spring balance structure of a flip bracket assembly, which reduces the resistance of the flip bracket assembly during flipping. The torsion spring can keep the flip bracket assembly stable at all times, reduce the risk of damage, and ensure driving safety.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A spring balance structure of a flip bracket assembly comprises a fixed block, a driving block, a connecting block, a movable block and a torsion spring, wherein the driving block and the connecting block are respectively rotatably connected to the fixed block and the movable block, and the torsion spring is installed on the fixed block and connected to the movable block.

[0008] Optionally, in an embodiment of the present utility model, the torsion spring is provided with a first free end and a second free end, the first free end is mounted on the fixed block, and the second free end is mounted on the movable block.

[0009] Optionally, in an embodiment of the present utility model, two first connection holes are provided on the fixing block.

[0010] Optionally, in an embodiment of the utility model, two second connecting holes are provided on the movable block.

[0011] Optionally, in an embodiment of the present invention, first docking holes matching the first connecting holes are formed at both ends of the driving block.

[0012] Optionally, in an embodiment of the present invention, second docking holes matching the second connecting holes are formed at both ends of the connecting block.

[0013] Optionally, in an embodiment of the present invention, the driving block and the connecting block are hollow structures to reduce weight.

[0014] Beneficial effects of the utility model

[0015] The utility model discloses a spring balancing structure of a flip bracket assembly. During the retraction process of the flip bracket assembly, the torsion spring provides the movable block with a torque in the retraction direction, thereby reducing the resistance of the bracket assembly during the flipping process, and can be driven by a relatively smaller power motor. When in the retracted state, the flip bracket assembly always remains stable under the torsion force of the torsion spring. During long-term driving vibration and impact, the impact on the locking mechanism of the flip bracket assembly can be reduced, and damage to the external driving mechanism or the locking mechanism of the flip bracket assembly can be avoided. The torsion spring can prevent the movable block of the flip bracket assembly from collapsing due to the action of gravity or the impact load generated by the pedal on the movable block, thereby avoiding problems such as shaking and abnormal noise during driving or reducing the vehicle's passability or even affecting driving safety.
