[0003] The carriage chassis support is mainly composed of a support plate, a transmission component, a base and a damping element. The base provides a stable support frame, and the damping element can buffer the vibration impact during driving. During operation, the support plate evenly disperses the weight of the carriage to the chassis through the base, and the damping element absorbs the road bumping energy to ensure stable operation of the carriage and reduce the shaking of goods and the wear of the chassis.
[0004] In the field of transportation today, some carriage chassis supports have obvious performance short boards in actual application. When facing the task of carrying goods, the limitations of their structural design make them unable to efficiently bear the weight of the goods. When the vehicle is in a driving state, especially when it encounters complex road conditions, this deficiency is more prominent. For example, during the overall turning of the automobile, due to inertia and centrifugal force, a large lateral pressure is generated. The traditional support structure is difficult to effectively disperse and buffer this lateral pressure, which can easily cause the support to be locally stressed too much, thereby causing problems such as deformation and damage of the support, seriously affecting the stability and safety of the goods, and even adversely affecting the driving performance of the carriage chassis and the entire vehicle.

[0034] The buffer mechanism comprises a rotating block 2, the rotating block 2 is rotatably connected at the top end of the base 1, the rotating block 2 is connected with the base 1 in a rotatable manner, so that when the vehicle body turns, the gravity on one side can be effectively weakened during the turning of the vehicle body, the force can be dispersed and buffered to a certain extent through the rotating mode, avoiding excessive pressure on one side due to the turning of the vehicle, ensuring the stability of the vehicle driving, the top end of the rotating block 2 is fixedly connected with a sleeve 3, the sleeve 3 provides a sliding space for the internal sliding part and a certain guiding effect, so that the subsequent related parts can stably slide along the axial direction, the sleeve 3 is slidably connected with a sliding ring 4 inside, the sliding ring 4 is a key part connected with the telescopic spring 5 and the damper 6, can slide up and down inside the sleeve 3 when stressed, and in turn drive the telescopic spring 5 to extend and retract and make the damper 6 work, the bottom end of the sliding ring 4 is fixedly connected with the telescopic spring 5, the telescopic spring 5 can be elastically deformed when subjected to external force, and can absorb and buffer the force;
[0035] The inside of the telescopic spring 5 is sleeved with a damper 6, which cooperates with the telescopic spring 5. When the telescopic spring 5 telescopes, the damper 6 can control the telescoping speed through its damping effect, avoiding over-telescoping or too-fast rebounding of the spring, so as to better weaken and buffer the force. The top end of the sliding ring 4 is fixedly connected to the bottom end of the transmission rod 7. The top end of the base 1 is provided with a supporting plate 16, which is directly used to contact or connect the tray and other components for carrying goods in the vehicle compartment, and is a direct force receiving surface for carrying the weight of goods.

Through the rotatable connection with multiple sleeve pipes 3, the connecting rod 9 can have a certain correlation between different sleeve pipes 3 when the force changes, play a role in synchronous coordination, and ensure that the forces between the buffer mechanisms are relatively balanced. The connecting rod 9 works cooperatively when dealing with complex force conditions. The top end of the base 1 is fixedly connected with a limiting block 10, the outside of which is in contact with the outside of the sleeve pipe 3.

[0038] The top end of the mounting block 8 is provided with a sliding groove 12, which provides space and guidance for the sliding of the fixing block 13, so that the fixing block 13 can slide according to the set trajectory, thereby realizing the dismounting function, the outside of the fixing block 13 is slidably connected in the inside of the sliding groove 12, and the outside of the fixing screw 15 is threadedly connected with the inside of the supporting plate 16, which not only ensures the firmness of the connection, but also facilitates the connection and dismounting through rotation operation, the bottom end of the sliding groove 12 is in the shape of an inclination, and the inclined design makes the fixing block 13 gradually and stably rotate into the inside of the mounting block 8 along the inclined groove, thereby ensuring the tightness and stability of the connection, the rear end of the connecting rod I 9 is rotatably connected with another sleeve 3, which further strengthens the correlation and cooperativeness between the sleeves 3 through the connecting rod I 9, and the outside of the limiting block 10 is in contact with the outside of the sleeve 3, thereby continuously exerting the limiting effect and ensuring the stable operation of the whole support system under various working conditions.

[0040] When it is necessary to clean the supporting plate 16 or to maintain and replace the whole flexible support component, the fixed block 13 is rotated to a suitable position through the rotating fixing screw 15, so that the supporting plate 16 can be slid out from the inside of the sliding groove 12, to realize the disassembly between the whole supporting plate 16 and the whole base 1, which is beneficial to the cleaning and maintenance requirements, when installing, the fixed block 13 is adjusted to a suitable position through the rotating fixing screw 15, then the whole fixed block 13 is slid into the inside of the mounting block 8 through the sliding groove 12, then the fixed block 13 is stably rotated into the inside of the mounting block 8 along the inclined groove formed in the inside of the mounting block 8 through the rotating fixing screw 15, and the connection between the whole supporting plate 16 and the whole base 1 is ensured to be stable through the threaded connection between the fixing screw 15 and the supporting plate 16, the quick disassembly and quick assembly improve the overall work efficiency.
