Abstract

Provided is a front protection structure of an electric tricycle. The front protection structure includes an inner cross beam, inner bevel edge beams which are symmetrically and fixedly connected ontothe left and right ends of the inner cross beam, an outer cross beam and two outer bevel edge beams; the outer end of the inner bevel edge beam is close to the direction of a tricycle body in the rear, the inner cross beam and the inner bevel edge beams are all fixedly connected with the front part of the tricycle body, the outer cross beam is arranged at the front part of the inner cross beam, and is parallel to the inner cross beam, and the outer cross beam is fixedly connected with the inner cross beam through two connecting beams perpendicular to the inner cross beam; the inner end of each outer bevel edge beam is hinged with the left and right ends of the outer cross beam separately; the two outer bevel edge beams are connected with the two inner bevel edge beams through buffer mechanisms; each buffer mechanism is composed of a first spring base fixedly connected onto the middle part of the corresponding inner bevel edge beam, a second spring base fixedly connected onto the middle part of the corresponding outer bevel edge beam, and a compression spring fixedly connected between the first spring base and the second spring base. The protection structure has deformation resilience capacity after deformation, has the function of energy absorption in the process of collision, and can better protect the safety of the electric tricycle and users.

Example Embodiment

[0016] The present invention will be further described below in conjunction with the drawings.

[0017] Such as figure 1 with figure 2 As shown, a front protective structure of an electric tricycle includes an inner cross beam 1, an inner hypotenuse beam 2, an outer cross beam 3, and two outer hypotenuse beams 4 fixedly connected to the left and right ends of the inner cross beam 1 symmetrically. The outer end of the beam 2 approaches the direction of the rear car body. The inner cross beam 1 and the inner beveled side beam 2 are both fixedly connected to the front of the car body. The outer cross beam 3 is arranged at the front of the inner cross beam 1, and the outer cross beam 3 is connected to the inner The cross beams 1 are parallel, and the outer cross beam 3 is fixedly connected to the inner cross beam 1 by two connecting beams 10 perpendicular to the inner cross beam 1;

[0018] The inner ends of the two outer hypotenuse beams 4 are hinged to the left and right ends of the outer cross beam 3 respectively;

[0019] The two outer bevel beams 4 and the two inner bevel beams 2 are connected by a buffer mechanism 5; the buffer mechanism 5 is fixedly connected to the outer bevel by a first spring seat 6 fixedly connected to the middle of the inner bevel beam 2 The second spring seat 7 in the middle of the beam 4 and the compression spring 8 connected between the first spring seat 6 and the second spring seat 7 are composed.

[0020] The front part of the inner beam is provided with an outer beam, the front part of the inner hypotenuse beam is provided with an outer hypotenuse beam, and the outer hypotenuse beam is hinged with the outer transverse beam, so that the outer hypotenuse beam and the inner hypotenuse beam are hinged. Set up a buffer mechanism, so that when the side of the front part of the car body is hit, the outer bevel beam will approach the car body and compress the buffer mechanism. Therefore, the impact energy can be absorbed by compressing the buffer mechanism. After the external force is eliminated, the buffer mechanism has elastic recovery capability, so that the outer bevel beam can be restored to its original position. The outer cross beam is connected to the inner cross beam by a vertical connecting beam, which can absorb part of the energy through the deformation of the outer cross beam when receiving a frontal impact. At the same time, the deformation of the outer cross beam does not directly affect the inner cross beam, and can pass through the inner cross beam and the outer cross beam. The double protection of the beam better protects the personal safety of the user and the vehicle body when they receive a frontal impact.

[0021] In order to make the ends of the inner and outer bevel beams smoother and avoid scratches with foreign objects, the outer ends of the inner bevel beam 2 and the outer bevel beam 4 are fixedly connected with a ball head 9.

[0022] In order to better absorb the impact force during the impact, the left and right ends of the outer cross beam 3 are respectively located outside the left and right ends of the inner cross beam 1.

[0023] In order to better absorb the impact force during impact, the outer end of the outer bevel beam 4 is located outside the inner bevel beam 2.

[0024] In order to better absorb the impact force upon impact, the angle between the inner hypotenuse beam 2 and the inner cross beam 1 is 30 degrees.
