Description

Technical Field

[0001] The utility model relates to the technical field of plastics, in particular to an energy-absorbing plastic assembly for a go-kart. Background Art

[0002] Plastic materials play an energy-absorbing role in kart design. Plastic energy-absorbing boxes or bumpers can absorb and disperse impact energy in the event of a collision, reducing damage to the driver and vehicle structure, but the disadvantage is low recovery ability and high maintenance cost.

[0003] The existing conventional single bar or single box structure can usually only absorb energy once, and after absorbing energy, the structural recovery is poor, resulting in high maintenance costs for the vehicle body. Therefore, a kart energy-absorbing plastic assembly is proposed to provide an energy-absorbing component for the front or rear of the kart frame, which can absorb energy twice and has a certain degree of recovery after the external force is removed, with low later maintenance costs and reduced damage to occupants. Summary of the invention

[0004] In view of the problems in the prior art, the utility model provides a kart energy-absorbing plastic assembly to provide an energy-absorbing component for the front or rear of the kart frame, which can absorb energy for a second time and has a certain degree of recovery after the external force is removed, with low subsequent maintenance costs and the effect of reducing damage to occupants.

[0005] The technical solution adopted by the utility model to solve the technical problem is a kart energy-absorbing plastic assembly, comprising:

[0006] A first energy absorbing part, used for absorbing external impact force;

[0007] A second energy absorbing part connected to the first energy absorbing part;

[0008] A mounting seat connected to the first energy absorbing part and the second energy absorbing part;

[0009] The U-shaped ferrule is arranged on the first energy absorbing part.

[0010] By adopting the above technical solution, an energy absorbing component is provided for the front or rear of the frame of the kart through an assembly consisting of the first energy absorbing part, the second energy absorbing part, the mounting seat and the U-shaped clamping sleeve. The energy absorbing component is a combination of the first energy absorbing part and the second energy absorbing part to form a double energy absorbing effect, thereby further improving the energy absorbing effect.

[0011] Specifically, the first energy absorbing part includes:

[0012] The first energy absorbing sheet;

[0013] A second energy absorbing sheet connected to the first energy absorbing sheet;

[0014] The third energy absorbing sheet is connected to the second energy absorbing sheet.

[0015] By adopting the above technical solution, the first energy absorbing part can initially absorb the external impact energy.

[0016] Specifically, the second energy absorbing part includes:

[0017] The fourth energy absorbing sheet;

[0018] The fifth energy absorbing sheet is connected to the fourth energy absorbing sheet.

[0019] By adopting the above technical solution, the external impact energy is secondarily absorbed by the second energy absorbing part.

[0020] Specifically, both ends of the first energy absorbing sheet and the fourth energy absorbing sheet are provided with mounting holes, and the mounting holes at both ends of the first energy absorbing sheet and the fourth energy absorbing sheet are fixedly connected to the mounting seat by bolts.

[0021] Specifically, the first energy absorbing sheet, the second energy absorbing sheet, the third energy absorbing sheet, the fourth energy absorbing sheet and the fifth energy absorbing sheet are all provided with through holes in the middle, screw rods are inserted into the through holes, and first nuts are respectively provided at both ends of the screw rods.

[0022] By adopting the above technical solution, the first energy absorbing part and the middle part of the second energy absorbing part are inserted in series through the screw rod, so that the first energy absorbing part and the second energy absorbing part can be on the same horizontal line.

[0023] Specifically, studs are respectively provided at both ends of the third energy absorbing piece, the U-shaped ferrule is clamped on the first energy absorbing piece, the second energy absorbing piece, the third energy absorbing piece, the fourth energy absorbing piece and the fifth energy absorbing piece, and the back of the U-shaped ferrule passes through the stud, and the end of the stud is threadedly tightened with a second nut.

[0024] By adopting the above technical solution, the top and bottom of the first energy absorbing part and the second energy absorbing part are clamped by the U-shaped clamping sleeve, so that the height between the first energy absorbing part and the second energy absorbing part is kept consistent.

[0025] Specifically, the mounting seat, the first energy absorbing sheet, the second energy absorbing sheet, the third energy absorbing sheet, the fourth energy absorbing sheet and the fifth energy absorbing sheet are all made of nylon material, and the first energy absorbing sheet, the second energy absorbing sheet, the third energy absorbing sheet, the fourth energy absorbing sheet and the fifth energy absorbing sheet are all curved structures.

[0026] By adopting the above technical solution, the energy-absorbing sheet with an arc-shaped structure has a certain degree of elastic deformation and can return to its original shape after the external force is removed, thereby absorbing the external impact force and forming a buffer and shock absorption.

[0027] The beneficial effects of the utility model are as follows: through the assembly consisting of the first energy absorbing part, the second energy absorbing part, the mounting seat and the U-shaped clamping sleeve, an energy absorbing assembly is provided for the front or rear of the frame of the kart. The energy absorbing assembly is formed by the combination of the first energy absorbing part and the second energy absorbing part to form a double energy absorbing effect. The energy absorbing sheet with an arc-shaped structure has a certain degree of elastic deformation and can have a certain degree of recovery after the external force is removed. The later maintenance cost is small, and the external impact force can be absorbed to form a buffer and shock absorption, so that the energy absorption effect is further improved, and the collision energy received by the vehicle body is absorbed, and the direct impact of the collision on the vehicle body structure is reduced, maintaining relative stability, and reducing injuries to the occupants. The existing conventional single bar or single box structure usually can only absorb energy once, and after energy absorption, the structural recovery is poor, resulting in high maintenance costs for the vehicle body.
