Problems solved by technology

[0003] Among them, there are many safety threats to the cockpit. Many cars are designed to improve the safety of cars after collisions with large objects such as cars, such as airbags. However, during high-speed driving, small external objects come into contact with the cockpit shell It will also pose a threat to safety, such as a high-altitude parabolic object, which will hit it after it contacts the top of the cockpit shell, causing damage, so that later maintenance is very troublesome, and it also consumes a certain amount of financial resources
[0004] Or, after a serious object hits the cockpit shell severely, it will also cause injury to the people inside it

Embodiment 1

[0051] See Figure 1 - Figure 4 As shown, the present embodiment is an object of which provides a new energy vehicle protection cockstone buffer structure, including the cavity of the vehicle body 100 and the vehicle body 100, and the vehicle body 100 is located at the top of the cockpit. The protective cavity 110 is opened. The protective cavity 110 is provided in the direction of the opening direction thereof, and the protection device 200 includes at least:

[0052] The protector 210, the top of the protective seat 210 is provided with a top plate 211, and the protective seat 210 is connected to the top plate 211 to form a sealed filling cavity, and the filling cavity is filled with an elastic filler, which can be filled with a foam, a liquid, preferably a foam, and protective seats The bottom of the 210 is bonded to the bottom wall within the protective cavity 110;

[0053] The telescopic elastic seat 220 includes a shrink column 222, and the shrink column 222 is disposed at th...

Embodiment 2

[0057] In order to increase the stability of the lifting column 222 in contact with the curved top wall, this embodiment is different from the first embodiment, please refer to Figure 4 with Figure 10 Disted, where:

[0058] The top of the shrinking column 222 is provided with a force member 2221, and the strip 2221 is a hemispherical structure, and the curved face is in contact with the top wall in the protective cavity 110 for supplying it in contact with the curved surface. Power point.

[0059] On the basis of the first embodiment, the top portion of the lifting column 222 is always in contact with the top wall in the protective cavity 110 to provide force to the lifting column 222. Point, to ensure the stability of the upper force of the shrink column 222, so that each of the shrink column 222 is in contact with the top wall within the protective cavity 110, and increase the protection strength of the upper housing of the rocker tank 222, and resolve The curved protective cav...

Embodiment 3

[0061] In order to fill the flexible foam in the filled cavity, the present embodiment is different from the first embodiment, please refer to Figure 5 with Figure 8 Disted, where:

[0062] The top plate 211 is slidably coupled to the inner wall of the protective seat 210, and the protective seat 210 is connected to the top plate 211 to form a filling elastic foam in the fill chamber, and the top plate 211 is provided with a sliding tube 2111 in the top of the top plate 211, and a sliding pipe 2111 is provided with a sliding position, and the slide tube 2111 Slide the lift column 222.

[0063] On the basis of the first embodiment, the shrinking column 222 is subjected to the extrusion pressure, and when it is slid to contact with the slung pipe 2111, it is still unable to dispersion pressure, at which point the lift column 222 is driven by the power member 2221. The sliding pipe 2111 and the top plate 211 are moved in synchronously, then the top plate 211 downward is extruded in t...

Abstract

The invention relates to the technical field of vehicle protection, in particular to a cab protection buffer structure for a new energy vehicle. The cab protection buffer structure comprises a vehicle body and a cab in the vehicle body, a protection cavity is formed in the top, located on the cab, of the vehicle body, and a plurality of protection devices are arranged in the protection cavity in the forming direction of the protection cavity. According to the device, part of extrusion force is counteracted through arranged telescopic columns under the elastic force action of buffer springs, so that impact force is buffered, a shell on the top of the cab is protected, damage caused by external impact is reduced, in addition, foam filled in the cavity can further buffer the extrusion force, and the deformation degree of the top shell of the cab after being excessively extruded is reduced, so that personnel in the cab are protected, and the safety of the cab after being impacted is improved.

Description

Technical field [0001] The present invention relates to the field of automotive protection, and in particular, relating to a new energy vehicle for protecting the cockpit buffer structure. Background technique [0002] At present, with the development of new energy vehicles, many new energy vehicles are not only improved in energy, but also improve the safety of the cockpit not only increase in energy. [0003] Among them, there are many security threats that are subject to the cockpit. Many cars are improved for the safety after the collision of large objects such as automobiles, such as airbags, but during high-speed travel, the external micro object is in contact with the cockpit housing It will also pose a threat to security, such as high-altitude parabolic, and the object causes hit to the top of the cockpit casing, forming damage, so that the later maintenance is very troublesome, while still consuming certain financial resources. [0004] Alternatively, after a severe obje...
