Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Specific implementations of the present invention are described in detail below with reference to specific embodiments.

Referring to fig. 1 to 4, in the suspension spring mechanism for a vehicle according to the embodiment of the present invention, the suspension spring mechanism for a vehicle includes a spring 1, fixing bases 2 slidably connected to the spring 1 are disposed at both upper and lower ends of the spring 1, a through slide 4 is further disposed on the upper fixing base 2, a connecting block 5 penetrating the fixing base 2 is further fixedly embedded at the upper end of the spring 1, and a through threaded hole 6 is further disposed on the connecting block 5;

the driving assembly 7 is installed on the fixed seat 2 above the spring 1, the driving assembly 7 comprises a base 71 which is embedded on the fixed seat 2 and has a cavity structure, the upper end of the base 71 is provided with a driving motor 72, the output end of the driving motor 72 extends into the base 71 and is fixedly embedded with a driving gear 73, the side end of the base 71 is also rotatably connected with a transmission screw 74, one end of the transmission screw 74 extends into the base 71 and is fixedly embedded with a driven gear 75 which is meshed with the driving gear 73;

wherein, the transmission screw 74 penetrates through the connecting block 5 and is meshed with the threaded hole 6;

and a fixed plate 8 is fixedly embedded on the fixed seat 2, and the other end of the transmission screw 74 is rotatably connected with the fixed plate 8.

It should be noted that: when the device is used, the driving motor 72 drives the transmission lead screw 74 to rotate through gear transmission, and the transmission lead screw 74 is meshed with the connecting block 5 fixed on the spring 1, so that when the transmission lead screw 74 rotates, the spring 1 can be directly driven to move, and the position of the spring 1 can be adjusted;

it should also be noted that: in the device, a driving gear 73 is meshed with two groups of driven gears 75, so that when the device works, two groups of transmission screw rods 74 can be driven to synchronously rotate at the same time, synchronous opposite or back movement of two groups of springs 1 is realized, and the position accuracy of the springs 1 during movement is ensured;
