Detailed Description
The utility model discloses a shock attenuation frame please combine and explain with reference to fig. 1 and 2 and 3.
The utility model discloses a shock-absorbing structure is applicable to the shock-absorbing structure of frames such as bicycle, balance car, scooter, electric bicycle, two wheeler, tricycle, four wheeler. Although the utility model discloses the saying of many places all adopt "balance car" the "smooth walking car", only for the convenience of explanation, do not be used for injecing the utility model discloses a application range and technical field.
As shown in fig. 1, the shock absorbing frame of the present invention includes a first frame 10, a second frame 20, a seat assembly 30; the first frame 10 and the second frame 20 are connected by a pin 40 (the structure of the pin is not shown in the figure, and only the pin is illustrated as a hole); the joint 50 or a part of the joint 50 of the first frame 10 and the second frame 20 is a slope 51 abutting against each other; the slope of the joint portion 50 of the second frame 20 is pressed against the slope of the joint portion 50 of the first frame 10; the pin 40 is disposed below the middle of the inclined surface 51 in the vertical direction.
With the balance car frame with the above structure, the seat assembly 30 is fixed on the second frame 20 or the first frame 10, and the seat assembly 30 receives the weight of the human body and applies a downward force to the first frame 10 and the second frame 20. At this time, since the joint portion of the first frame 10 and the second frame 20 adopts the pin connection structure, the first frame 10 and the second frame 10 are automatically forced to be bent downward relatively, in this case, the inclined surfaces of the joint portion of the first frame 10 and the second frame 20 are forced to be in contact with each other, and a frictional force along the inclined surfaces is generated, thereby preventing the relative bending of the first frame 10 and the second frame 20. Therefore, the buffer force is generated, and the vibration of the frame is slowed down.
In addition, the seat assembly 30 is preferably fixed to the second frame 20. As shown in fig. 1, the seat assembly 30 applies a downward force to the second frame 20, and the second frame 20 is forced to rotate and sink downward at the joint portion, and at this time, the inclined surface of the second frame 20 generates a friction force on the inclined surface of the first frame 10, and prevents (non-rigidly prevents) the downward sliding of the second frame 20, thereby generating a damping force, thereby achieving a shock-absorbing effect.
In addition, as shown in fig. 2, the joint 50 of the first frame 10 and the second frame 20 may further include portions 52 and 53 that are nested with each other, so that the strength of the joint of the first frame 10 and the second frame 20 may be reinforced, and the support force and durability of the frame may be increased.
In addition, as shown in fig. 2, the joint portion 50 of the first frame 10 and the second frame 20 may further include a through hole 41, a hollow structure 54, and a protruding portion 55; the protruding portion 55 is provided with a hole matching with the through hole 41, the protruding portion 55 is embedded into the hollow structure 54, and the pin shaft 40 is inserted into the through hole 41 and the hole. This further increases the strength of the joint between the first frame 10 and the second frame 20, and increases the support force and durability of the frame
In addition, the outer part of the joint part 50 can be sleeved with a ring sleeve 60, so that the joint part is protected to a certain extent, the strength of the joint part is increased, and the joint part is prevented from being broken to cause injury to a user.
As shown in fig. 3, the first frame 10 is a front wheel frame, and the second frame 20 is a rear wheel frame; the joint 50 is provided at a horizontal portion of the first frame 10 and the second frame 20.
The first frame 10 is a rear wheel frame, and the second frame 20 is a front wheel frame;
the joint is provided at a portion in the horizontal direction on the first frame 10 and the second frame 20.
As can be understood from the above embodiments, the seat assembly may be disposed on the first frame 10 or may be disposed on the second frame 10.
The inclined surfaces of the joint portions 50 abutting against each other may be directed toward the front wheel frame or the rear wheel frame.
In addition, the contact surface of the inclined surface 51 is a rough surface. This increases the frictional force between the inclined surface of the first frame 10 and the inclined surface of the second frame 20, thereby increasing the shock-absorbing effect.
The present invention discloses the specific embodiments, but the present invention is not limited thereto, and any person skilled in the art can make modifications without departing from the spirit of the present invention, and the protection scope of the present invention is subject to the scope of the claims.
