Description

Technical Field

[0001] The utility model relates to the field of electric tricycles, and particularly relates to a buffer damping bumper device. Background Art

[0002] An electric tricycle is a three-wheel transport vehicle powered by a battery and driven by a motor for carrying goods or people. The electric tricycle has the advantages of strong applicability, flexibility, simple maintenance, convenient repair, low price, etc., and can flexibly travel through narrow roads. The electric tricycle has a reverse switch, which can conveniently realize the forward and reverse driving functions, which is very practical in narrow alleys and small lanes. It is very convenient for both driving and parking. It is widely used in short-distance transportation fields such as families, urban and rural areas, individual rentals, factories, mines, sanitation, and community cleaning.

[0003] At present, the front bumper of the electric tricycle is a steel pipe structure without any buffer device. In case of accidental impact, the impact feeling is directly transmitted to the driver, which is likely to cause danger to the driver. Content of the Utility Model

[0004] Utility Model Objective: To provide a buffer damping bumper device to solve the above problems existing in the prior art.

[0005] Technical Solution: A buffer damping bumper device includes a bumper support body, characterized in that a buffer component and a buffer pad are provided on the working surface of the bumper support; the buffer component is placed between the bumper support and the buffer pad, and both the buffer component and the buffer pad are multiple and symmetrically distributed on the working surface of the bumper support.

[0006] In a further embodiment, the buffer component includes a protective bent beam and a stress spring; one end of the stress spring is connected to the bumper support, and the other end is connected to the protective bent beam, and there are multiple stress springs, and a predetermined working distance is left between the multiple stress springs.

[0007] In a further embodiment, the left and right ends of the stress spring are respectively connected to the protective bent beam and the bumper support through an upper end cover and a lower end cover.

[0008] In a further embodiment, one end of the upper end cover is connected to the stress spring, and the other end is connected to the protective bent beam; one end of the lower end cover is connected to the stress spring, and the other end is connected to the bumper support.

[0009] In a further embodiment, the protective bent beam, the buffer pad and the bumper support all have a predetermined bending arc.

[0010] Beneficial effects: The utility model relates to a buffer damping bumper device, belonging to the field of electric tricycles, which includes a bumper support body. A buffer assembly and a buffer pad are provided on the working surface of the bumper support. The buffer assembly is arranged between the bumper support and the buffer pad, and both the buffer assembly and the buffer pad are multiple and symmetrically distributed on the working surface of the bumper support. By means of the provided buffer assembly and buffer pad, the front bumper is changed into a buffer device, which can effectively reduce the impact feeling of the driver when the vehicle is hit heavily during driving. In case of a general impact, the buffer pad can recover by itself, without causing substantial damage to the bumper, and also reducing the situations such as structural depression and paint peeling caused by general impacts, while effectively improving the safety of the driver.

[0014] In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, some well-known technical features are not described to avoid confusion with the present utility model.

[0015] Embodiment 1:

[0016] The buffer damping bumper device proposed in this embodiment includes the main body of the bumper bracket 6, and is characterized in that a buffer assembly and a buffer pad 1 are provided on the working surface of the bumper bracket 6; the buffer assembly is disposed between the bumper bracket 6 and the buffer pad 1, and both the buffer assembly and the buffer pad 1 are multiple and are symmetrically distributed on the working surface of the bumper bracket 6. The buffer assembly includes a protective curved beam 2 and a stress spring 4; one end of the stress spring 4 is connected to the bumper bracket 6, and the other end is connected to the protective curved beam 2, and there are multiple stress springs 4, and a predetermined working distance is left between the multiple stress springs 4. The left and right ends of the stress spring 4 are respectively connected to the protective curved beam 2 and the bumper bracket 6 through an upper end cover 3 and a lower end cover 5. One end of the upper end cover 3 is connected to the stress spring 4, and the other end is connected to the protective curved beam 2; one end of the lower end cover 5 is connected to the stress spring 4, and the other end is connected to the bumper bracket 6. The protective curved beam 2, the buffer pad 1 and the bumper bracket 6 all have a predetermined bending arc.

[0017] Embodiment 2:

[0018] On the basis of Embodiment 1, the stress spring 4 provided in this application is a damping spring, and the buffer pad 1 is a rubber buffer pad 1, thereby forming a buffer device with an elastic body. During the driving of the vehicle, when encountering an impact ahead, the impact force received is first transmitted to the rubber buffer pad 1. The rubber buffer pad 1 absorbs the first wave of kinetic energy. If the impact force is small, the kinetic energy terminates at the rubber buffer pad 1; if the impact force is large and exceeds the maximum absorption stress value of the buffer pad 1, the impact force is transmitted to the stress spring 4 through the rubber buffer pad 1, and the kinetic energy received by the stress spring 4 will be converted into the deformation energy inside the elastic body and gradually consumed and dispersed. This process of absorbing and dissipating energy weakens the impact force transmitted to the driver when the vehicle is impacted, thereby ensuring the safety of the driver and also ensuring the integrity of the vehicle and other structures. After the elastic body of the front bumper is deformed accordingly, it will automatically return to its original shape.

[0019] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as a limitation of the present invention itself. Various changes can be made in its form and details without departing from the spirit and scope of the present invention defined by the appended claims.
