Description

Technical Field

[0001] The utility model relates to the technical field of electric tread plates, in particular to an electric tread plate that runs smoothly. Background Art

[0002] Electric running boards are a type of equipment installed on cars, mainly used to improve the convenience of getting on and off the car for drivers and passengers. Especially for some SUVs, MPVs and other models, due to the high body, passengers may need some support when getting on and off the car. At this time, electric running boards come in handy.

[0003] When the passenger opens the door, the electric step automatically extends to facilitate the passenger to get on and off the vehicle. After the passenger gets on the vehicle, the electric step automatically retracts. Some high-end models also have a memory function that can automatically adjust the height of the step according to the driver's settings.

[0004] There are many types of electric step boards, including built-in electric step boards, external electric step boards, side-sliding electric step boards, wheelchair boarding pedals and other types.

[0005] Among them, the push-type electric tread is also a commonly used type of tread. This type of tread has a complex structure and high installation cost, and uses an electric guide rail to control the contraction and movement of the tread. However, the tread is mainly used to facilitate passengers getting on and off the vehicle. Therefore, when the passengers step on the tread, it will be subjected to a downward pressure. When the pedal is often subjected to downward pressure, it will not only cause the guide rail or slider to be deformed and damaged, but it will also affect the normal movement of the tread for a long time and increase the maintenance cost.

[0006] Therefore, it is necessary to invent a smooth-running electric stepping plate to solve the above problems. Utility Model Content

[0027] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] The present utility model provides a smoothly - running electric tread plate as shown in Figures 1-5 which includes a housing 1 and a pedal 2. The housing 1 is slidably sleeved outside the pedal 2. The housing 1 and the pedal 2 of the electric tread plate are designed to be slidably sleeved, making the pedal 2 run more smoothly during operation. A driving mechanism 4 is arranged outside one end of the housing 1, and a flat - push mechanism 5 is arranged inside the tail end of the housing 1 and on one side of the driving mechanism 4. The flat - push mechanism 5, as the driving component of the pedal 2, compared with the existing guide - rail design, can prevent the downward pressure on the push rod 51 when the pedal 2 is stressed, thereby avoiding damage to the push rod 51 and affecting its movement;

[0029] The flat - push mechanism 5 includes:

[0030] A push rod 51, which is arranged inside the tail end of the housing 1. The push rod 51 is suspended inside the housing 1. A connecting rod 53 is fixedly installed at the top of the front end of the push rod 51, and a spring 54 is horizontally and fixedly installed at the middle part on one side of the push rod 51. The front end of the spring 54 is fixedly connected to the tail end of the pedal 2;

[0031] A shaft rod 52, which is rotatably installed inside the tail end of the housing 1 near one side of the driving mechanism 4. The shaft rod 52 is fixedly connected to the tail end of the push rod 51, and the top end of the shaft rod 52 penetrates through the top of the housing 1.

[0032] Further, in the above technical solution, a guiding groove 3 is provided on the top of the housing 1 and on the side away from the driving mechanism 4. The top end of the connecting rod 53 penetrates through the guiding groove 3. The curvature of the guiding groove 3 is the same as the path of the push rod 51 moving in a circular motion. The front end of the push rod 51 is connected through the connecting rod 53, so that the push rod 51 is kept suspended, and the push rod 51 can effectively push the pedal 2.

[0033] Further, in the above technical solution, the driving mechanism 4 includes a bidirectional motor 41. The bidirectional motor 41 is vertically and fixedly installed at one end of the housing 1. The output end of the bidirectional motor 41 faces upward, and a transmission wheel 42 is fixedly installed at the output end of the bidirectional motor 41.

[0034] Further, in the above technical solution, a transmission wheel 42 is fixedly installed at the top end of the shaft rod 52. A belt 43 is sleeved outside the transmission wheel 42 at the output end of the bidirectional motor 41 and the transmission wheel 42 at the top end of the shaft rod 52. Thus, the movement of the flat push mechanism 5 is controlled through the driving mechanism 4 to provide sufficient power.

[0035] Further, in the above technical solution, sliding grooves 11 are provided on the inner walls at both ends of the housing 1. Connecting pieces 7 are fixedly installed at the edge positions at both ends of the housing 1. Roller wheels 21 are rotatably installed on both sides of the tail end of the pedal 2. The roller wheels 21 are slidably connected with the sliding grooves 11 in a matching manner, which improves the sliding performance of the electric tread board and maintains the stability of the pedal 2 moving back and forth inside the housing 1, preventing the pedal 2 from shifting when moving back and forth.

[0036] Further, in the above technical solution, a plurality of ball bearings 6 are rotatably installed on the inner walls at the upper and lower ends of the housing 1. The outer walls at the upper and lower ends of the pedal 2 are in contact with the ball bearings 6 on the inner walls at the upper and lower ends of the housing 1. Thus, when the pedal 2 moves back and forth inside the housing 1, the friction between the upper and lower surfaces of the pedal 2 and the upper and lower inner walls of the housing 1 is reduced.

[0037] When the smooth-running electric tread board provided by the present utility model is in use, its working process is as follows:

[0038] When the electric tread board is working, the bidirectional motor 41 in the driving mechanism 4 rotates forward. Then, the transmission wheel 42 at the output end of the bidirectional motor 41 rotates, which drives the belt 43 to rotate. Then, the transmission wheel 42 on the shaft rod 52 is synchronously driven to rotate, which causes the shaft rod 52 to rotate. That is, the shaft rod 52 drives the push rod 51 to move towards the tail end direction of the pedal 2. As the push rod 51 rotates, the front end of the push rod 51 pushes the tail end of the pedal 2, causing the pedal 2 to move towards the front end of the housing 1. When the push rod 51 rotates to a certain angle, the bidirectional motor 41 stops rotating, and the front end of the push rod 51 abuts against the tail end of the pedal 2 to prevent the pedal 2 from moving backward;

[0039] When the pedal 2 is retracted, the bidirectional motor 41 rotates in the reverse direction. Consequently, the shaft rod 52, the push rod 51, and the transmission wheel 42 all rotate in the reverse direction. Then, the push rod 51 starts to move away from the tail end of the pedal 2. As the push rod 51 moves away, since the tail end of the pedal 2 is connected to the push rod 51 through the spring 54, when the push rod 51 rotates in the reverse direction, the spring 54 synchronously pulls the tail end of the pedal 2 to move it backward, thereby causing the pedal 2 to return to the inside of the housing 1.

[0040] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
