Problems solved by technology

[0003] At present, the shock absorber used in new energy vehicles often uses a pneumatic cylinder and a spring to jointly play a shock absorbing role. Since the air inside the pneumatic cylinder is squeezed and the pressure increases when the pneumatic cylinder is stressed, when the pneumatic cylinder returns to its original state , because the spring and the pneumatic cylinder jointly release the stored elastic potential energy, and there are no other components to buffer this part of the force, so that the current shock absorber has a large rebound force after shock absorption, and the shock absorption effect is not ideal; at the same time, the current The shock absorber for new energy vehicles only uses a set of pneumatic cylinders and springs for shock absorption, which may have a very limited effect. When this type of shock absorber is used on a heavier type of new energy vehicle, it will also greatly affect the shock absorber. The effect of using

Embodiment 1

[0033] Example 1, such as figure 1 , 2 , 5, 6, 7 and 8, when the shock absorber for new energy vehicles is stressed, the movable rod 11 gradually moves to the inside of the cylinder body 10, pushing the piston assembly 13 down inside the cylinder body 10, forcing the piston assembly 13 The pressure in the bottom space increases, the telescopic rod 133 shortens, and the first piston 134 and the second piston 132 approach each other. When the pressure in the space below the second piston 132 is high, the sealing plug 806 is forced to move downward, so that the installation The through hole of the ring 801 is blocked, so that the air inside the cylinder body 10 runs from the through hole of the installation ring 801 into the interior of the inner installation chamber 805, and then passes through the through hole 804, the filter screen and the port 12 and then is discharged to the external environment In the process, the lifting rod 4 is shortened by force, the first spring 2 is ...

Embodiment 2

[0034] Example 2, such as Figure 1-8 As shown, when the second spring 5 and the first spring 2 release the elastic potential energy, the upper mounting seat 1 and the movable rod 11 are pushed up, and the piston assembly 13 moves up inside the cylinder body 10, so that the space under the piston assembly 13 is under negative pressure. state, forcing the outside air to enter the push-off sealing cover 809 and enter the interior of the cylinder 10, so that the movable rod 11, the piston assembly 13 and the cylinder 10 together play the role of syringe pumping, which greatly alleviates the second The elastic potential energy released by the spring 5 and the first spring 2 prevents the large rebound force of the shock absorber from making the entire new energy vehicle more bumpy.

[0035] Working principle: When the shock absorber for new energy vehicles is stressed, the movable rod 11 gradually moves to the inside of the cylinder body 10, pushing the piston assembly 13 down insi...

Abstract

The invention discloses a shock absorber for a new energy automobile. The shock absorber for the new energy automobile comprises a cylinder body, a movable rod is arranged in the inner part of the cylinder body, the bottom end of the movable rod extends to the inner part of the movable rod and is provided with a piston assembly, an upper mounting base is mounted at the top end of the movable rod,the outer side of the cylinder body is sleeved with a movable plate, lifting rods are symmetrically hinged to the two ends of the top of the movable plate, and the top ends of the lifting rods are hinged to the two ends of the bottom of the upper mounting base. According to the shock absorber for the new energy automobile, through cooperative use of an oil seal assembly, a lower mounting base, a mounting plate, an air inlet and outlet assembly, the cylinder body, the movable rod, a through opening, the piston assembly and a through groove, the movable rod, the piston assembly and the cylinderbody jointly play a role in air exhaust of a needle cylinder by means of force generated by releasing elastic potential energy through a second spring and a first spring, and therefore, force generated by releasing elastic potential energy by the second spring and the first spring is relieved, and the whole shock absorber for the new energy automobile is more stable during shock absorption.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a shock absorber for new energy vehicles. Background technique [0002] With the development of society and the improvement of people's living standards, automobiles have become an indispensable means of transportation for modern people's daily travel. With the popularity of automobiles today, people's demand for automobiles is not only comfort, fuel economy, but also safety performance. It is the primary factor that people consider when buying a car. When the car is running, the suspension system vibrates due to the impact of the elastic element. In order to improve the ride comfort of the car, a shock absorber is installed in the suspension in parallel with the elastic element. Jointly undertake the task of reducing impact and shock absorption. [0003] At present, the shock absorber used in new energy vehicles often uses a pneumatic cylinder and a spring to jointly play a ...
