Description

Technical Field

[0001] The utility model relates to the technical field of automotive electric pedals, in particular to a bracket assembly for an automotive electric pedal. Background Art

[0002] Among automobiles, there are vehicles with a relatively high chassis height from the ground, such as pickup trucks, off-road vehicles, etc. The step height for getting on and off these vehicles far exceeds the comfortable step height of the human body. At this time, installing an electric pedal on the vehicle can create a boarding step with a suitable height for users and assist them in getting on and off the vehicle smoothly. Currently, most electric pedals use a four-link structure, which can only move in the Y and Z directions and cannot move in the X direction. Due to the shape of the side skirt of some vehicle models, the electric pedal with a four-link structure is relatively far from the rear door of the vehicle in the X direction. In this way, even when the pedal is fully opened, users can only step on a small part or cannot step on the pedal when getting on and off the vehicle from the rear door position. The swing arm structure electric pedal can move in the X, Y, and Z directions, which can avoid the problem that when the pedal is fully opened, users can only step on a small part or cannot step on the pedal when getting on and off the vehicle from the rear door position of the vehicle. However, the existing swing arm structure electric pedal must use an active swing arm structure and a driven swing arm structure in cooperation, that is, two sets of swing arm structures need to be used in cooperation at the same time, and a single swing arm structure cannot be used alone. Due to the poor stability of a single swing arm structure, the pedal is prone to free rotation, so there are safety hazards when users use it, and the production cost of an electric pedal using two sets of swing arm structures at the same time is relatively high. For example, the Chinese utility model patent with the document number CN 106585499 A, the publication date is April 26, 2017, and the patent name is an automotive swing arm type electric pedal. It discloses a structure including a main swing arm, a sub-swing arm, and a footrest. The main swing arm includes a main swing arm bracket and a main swing support arm, and the sub-swing arm includes a sub-swing arm bracket and a sub-swing support arm. The main swing arm bracket and the sub-swing arm bracket are both installed on the same side of the vehicle body bottom; the main swing support arm is provided with a first fixed axis and a first moving axis that are parallel to each other, and the sub-swing support arm is provided with a second fixed axis and a second moving axis that are parallel to each other. The distance from the first fixed axis to the first moving axis is equal to the distance from the second fixed axis to the second moving axis; one end of the main swing support arm is rotatably connected to the main swing arm bracket and can rotate relative to the main swing arm bracket around the first fixed axis, and the other end of the main swing support arm is rotatably connected to the footrest and can rotate relative to the footrest around the first moving axis; one end of the sub-swing bracket is rotatably connected to the sub-swing arm bracket and can rotate relative to the sub-swing arm bracket around the second fixed axis, and the other end of the sub-swing bracket is rotatably connected to the footrest and can rotate relative to the footrest around the second moving axis; a driving motor for driving the main swing support arm to rotate around the first fixed axis is installed on the main swing arm bracket. The technical solution it adopts is an electric pedal that must use two sets of swing arm structures at the same time. Therefore, a solution to the problem that the existing swing arm structure electric pedal must use two sets of swing arm structures at the same time is needed. Summary of the Utility Model

[0032] The present utility model will be further described below in conjunction with the accompanying drawings:

[0033] As Figure 1 , Figure 2 , Figure 3 and Figure 7 shown, the present utility model provides a bracket assembly for an electric pedal of an automobile. The bracket assembly 1 includes a base 11 and a support portion 14. A first rotating arm 12 and a second rotating arm 13 are provided between the base 11 and the support portion 14, and the first rotating arm 12 and the second rotating arm 13 are adjacent to each other. Both ends of the first rotating arm 12 and the second rotating arm 13 are respectively rotatably connected to the base 11 and the support portion 14. By driving the first rotating arm 12 to rotate through the driving element 2, the second rotating arm 13 rotates synchronously, or the second rotating arm 13 can be driven to rotate through the driving element 2, and the first rotating arm 12 rotates synchronously. In this way, the first rotating arm 12 and the second rotating arm 13 drive the support portion 14 to translate in the X direction, Y direction and Z direction, so as to realize the opening or retraction of the support portion 14. The support portion 14 can be in the shape of a plate, or in the shape of a block, or can be set into other shapes convenient for the foot to step on. When only a single bracket assembly 1 is used, the support portion 14 can be directly used as a pedal to assist the user to get on and off the vehicle smoothly.

[0034] As Figure 1 , Figure 3 and Figure 4 shown, on the basis of the above embodiment, further, both ends of the first rotating arm 12 and the second rotating arm 13 are respectively rotatably connected to the base 11 and the support portion 14 through a rotating member 15. The rotating member 15 can be a pin shaft, or a rotating shaft, or other parts that can realize rotation.

[0035] As Figure 1 and Figure 8As shown, on the basis of the above-mentioned embodiment, further, both the first rotating arm 12 and the second rotating arm 13 are in a straight shape. The first rotating arm 12 and the second rotating arm 13 can also be approximately in a Z shape, and the first rotating arm 12 and the second rotating arm 13 can also be set into other suitable shapes. Wherein, both the first rotating arm 12 and the second rotating arm 13 include a first end portion 121 and a second end portion 122. If both the first rotating arm 12 and the second rotating arm 13 are in a straight shape, then the first end portions 121 and the second end portions 122 of the two are located on a plane. If both the first rotating arm 12 and the second rotating arm 13 are approximately in a Z shape, then the plane of the first end portion 121 of the first rotating arm 12 and the second rotating arm 13 is higher than the plane of the second end portion 122. The advantage of this is that when the vehicle chassis is too high, the second end portion 122 is lower than the first end portion 121, so that the height of the support portion 14 from the ground is lower, which is convenient for the user to get on and off the vehicle at a comfortable step height.

[0036] As Figure 5 and Figure 6 shown, on the basis of the above-mentioned embodiment, further, the rotation angle range of the first rotating arm 12 and the second rotating arm 13 is 0 to 130°. When the rotation angle of the first rotating arm 12 and the second rotating arm 13 reaches more than 95°, the support portion 14 is in a fully open state. At this time, the height of the support portion 14 from the ground is appropriate, which is convenient for the user to get on and off the vehicle.

[0037] As Figure 1 、 Figure 2 、 Figure 4 、 Figure 9 and Figure 10As shown, on the basis of the above embodiment, further, the number of bracket assemblies 1 is one or two or three or four. The bracket assembly 1 of the utility model solves the problem that the existing electric pedal must use two sets of bracket assemblies 1 at the same time. The bracket assembly 1 of the utility model can be used alone, and the support part 14 can be directly used as the pedal 5; multiple bracket assemblies 1 can also be used in combination according to requirements, and multiple support parts 14 are used as the support structure of the pedal 5, and one pedal 5 is fixedly installed on multiple support parts 14. When more than two bracket assemblies 1 are used, the driving element 2 can be installed on one of the bracket assemblies 1, that is, the main bracket assembly 1 and multiple auxiliary bracket assemblies 1 are formed; the driving element 2 can also be installed on multiple bracket assemblies 1, and multiple driving elements 2 work at the same time. The driving element 2 is a motor, and the driving element 2 is connected to the first rotating arm 12 or the second rotating arm 13 in transmission. The driving element 2 can achieve power transmission by realizing transmission connection with one of the first rotating arm 12 or the second rotating arm 13. Specifically, to achieve a transmission connection between the driving element 2 and the first rotating arm 12, the driving element 2 can use a motor, or an electric cylinder, or other driving devices that can achieve the same function, such as a reduction motor, a stepping motor, etc. When a reduction motor is used, the output shaft of the reduction motor is sleeved and fixedly connected with the rotating member 15, and then the first rotating arm 12 and the rotating member 15 are fixedly connected by a key, so that the reduction motor can drive the first rotating arm 12 to rotate.

[0038] like Figure 7 and Figure 10 As shown, on the basis of the above embodiment, further, the angle between the top surface of the support portion 14 and the horizontal plane is 3 to 6 degrees. In this embodiment, the angle between the top surface of the support portion 14 and the horizontal plane is 5 degrees, that is, the top surface of the support portion 14 is inclined toward the base 11, so that the support portion 14 can provide a support force for the user's feet toward the direction of the car body 4, and prevent the user's feet from sliding away from the car body 4 when stepping on the support portion 14, thereby ensuring the user's safety.

[0039] like Figure 1 and Figure 4 As shown, on the basis of the above embodiment, further, a buffer pad 3 is fixedly installed on the base 11 at the outer side of the first rotating arm 12 and the second rotating arm 13. The buffer pad 3 reduces the vibration when the first rotating arm 12 and the second rotating arm 13 contact and collide with the base 11, thereby ensuring the stability of the bracket assembly 1.

[0040] like Figure 1 and Figure 10As shown in the figure, (1) during installation, select whether to use a single bracket assembly 1 or multiple bracket assemblies 1 in combination as needed. For example, when installing two sets of bracket assemblies 1 on the vehicle body 4 for combined use, the specific operation method is to fixedly install the two bases 11 on the vehicle body 4 (pickup truck or off-road vehicle) through screws. Finally, fixedly install the pedal 5 on the two support parts 14 of the two sets of bracket assemblies 1 through screws; among them, when the base 11 is installed on the vehicle body 4, a certain inclination angle needs to be set in the Z direction. The larger the inclination angle, the greater the height that the pedal 5 can descend in the Z direction. The inclination angle is specifically set according to the actual situation. Such as Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 10 As shown in the figure, (2) during operation, the starting position of the bracket assembly 1 is the fully retracted state, that is, the bracket assembly 1 is in a state of being retracted near the chassis of the vehicle body 4 (inside the vehicle). When the user needs to use the pedal 5, the driving element 2 works to drive the first rotating arm 12 to rotate forward, and the second rotating arm 13 rotates synchronously. The first rotating arm 12 and the second rotating arm 13 drive the support part 14 to translate in the X, Y, and Z directions. When the first rotating arm 12 and the second rotating arm 13 rotate 100°, the support part 14 completely extends outside the vehicle body 4 and the height from the ground is appropriate. At this time, the bracket assembly 1 is in the fully opened state, that is, the bracket assembly 1 is in a state of extending away from the chassis of the vehicle body 4 (outside the vehicle). The user can get on and off the vehicle with the help of the pedal 5. Since the height of the pedal 5 from the ground is appropriate, the height of the user's up and down steps is within the comfortable step height of the human body, and the user feels good; when the user does not need to use the pedal 5, the driving element 2 works to drive the first rotating arm 12 to rotate in the reverse direction, and the second rotating arm 13 rotates synchronously. The first rotating arm 12 and the second rotating arm 13 drive the support part 14 to translate in the X, Y, and Z directions. When the first rotating arm 12 and the second rotating arm 13 rotate 100°, the support part 14 retracts near the chassis of the vehicle body 4. At this time, the bracket assembly 1 is in the fully retracted state, that is, the bracket assembly 1 is in a state of being retracted near the chassis of the vehicle body 4 (inside the vehicle) again.
