Technical Field

[0001] The utility model relates to the technical field of shock absorbing devices, in particular to a floating shock absorbing device for an intelligent car. Background Art

[0002] Smart carts are also called automatic navigation material transport carts. They can transport goods from A to B according to the planned route. However, since the cart moves according to the planned route, when the cart moves on the planned route with an uneven road surface, the body of the cart is prone to shaking, causing the goods on the cart to easily fall off. Therefore, smart carts are usually installed with floating shock absorbers to reduce the shaking of the body.

[0003] However, when the existing floating shock-absorbing device of the intelligent car is in use, since the shock-absorbing device usually relies on the shock-absorbing spring to achieve shock absorption, when the shock-absorbing spring frequently reaches the extreme deformation value, the floating connecting part connected to it is easy to rub against the fixed structure in the device, causing the floating connecting part to be more prone to serious wear; in addition, during the use of the existing shock-absorbing device, it is impossible to adjust the tension of the shock-absorbing spring, so that the floating amplitude of the entire shock-absorbing device cannot be controlled, which is not convenient for the adaptation of the floating shock-absorbing device to the intelligent car.

[0023] like Figures 1 to 4 As shown, the floating shock absorbing device of the intelligent car in this embodiment includes a chassis 1, and the four corners of the top of the chassis 1 are fixedly connected with a sleeve box 2, the top of the sleeve box 2 is provided with a shock absorbing spring 3, the top of the shock absorbing spring 3 is fixedly connected with an I-shaped plate 4, the middle of the I-shaped plate 4 is provided with a wire rope 8, the middle of the top of the chassis 1 is fixedly connected with a sleeve 9, the middle of the one side wall of the sleeve 9 is threaded with a first screw 11, one end of the first screw 11 is fixedly connected with a torsion bar 10, both sides of the bottom end of the I-shaped plate 4 are fixedly connected with support rods 6, the bottom end of the support rod 6 is threaded with a second screw 14, the bottom end of the second screw 14 is fixedly connected with a support plate 7, and the bottom end of the support plate 7 is embedded with a rubber pad 15.

[0024] Specifically, the chassis 1 is the chassis 1 of the floating shock absorbing device, which can replace the chassis 1 of the original smart car, so that the device can form a complete body with the smart car, reducing the abrupt feeling brought by the device to the overall smart car. The function of the box 2 is to separate the wheel driving system of the smart car from the car, thereby realizing the shock absorption of the whole car. The function of the I-shaped plate 4 is to suspend the upper part of the smart car, so that the smart car can be in a suspended state on the chassis 1, which is conducive to the vibration reduction spring 3 to weaken the vibration transmitted by the wheel. The wire rope 8 can adjust the distance between the I-shaped plate 4 and the chassis 1, so that the tension of the vibration reduction spring 3 can be adjusted. A circular hole is opened in the middle of the top of the sleeve 9, and the circular hole can make the wire rope 8 pass through the top of the sleeve 9 smoothly, so as to facilitate the traction of the wire rope 8 on the I-shaped plate 4. Both ends of the first screw 11 are located on the outside of the sleeve 9, so that the first screw 11 can be engaged with the steel through thread. The wire rope 8 is wound up or unfolded, thereby realizing the traction of the wire rope 8 on the I-plate 4. A pinch plate is fixed to the side wall of the torsion bar 10, so that the torsion bar 10 exerts more force when twisting the first screw rod 11, thereby realizing the threaded engagement and rotation of the first screw rod 11 and the sleeve 9. A threaded channel is opened inside the support rod 6, so that the second screw rod 14 can be engaged and connected with the support rod 6 through the thread. At the same time, the second screw rod 14 can be fixed with the support rod 6 at any time through the thread, so that the length of the second screw rod 14 entering the support rod 6 can also be flexibly adjusted, thereby facilitating the user to adjust the distance between the support plate 7 and the chassis 1. The support plate 7 and the rubber pad 15 can extend the bottom end of the I-plate 4, so that when the I-plate 4 moves with the shock-absorbing spring 3 to about to contact and rub with the top of the sleeve box 2, the support plate 7 and the rubber pad 15 can contact the chassis 1 before the I-plate 4, so that the I-plate 4 is not easy to rub with the top of the sleeve box 2, thereby reducing the probability of serious wear of the I-plate 4.

[0025] Furthermore, grooves 12 are provided on the inner side of the box 2, and the bottoms of the grooves 12 are not closed. The driving wheels required for the intelligent car to move can be installed inside the grooves 12, so that the walking structure and the bearing platform of the intelligent car can be separated by the chassis 1, thereby realizing floating shock absorption of the intelligent car.

[0026] Furthermore, the top end of the shock-absorbing spring 3 is fixedly connected to the bottom end of the I-shaped plate 4, and the bottom end of the shock-absorbing spring 3 is fixedly connected to the top end of the sleeve box 2. The shock-absorbing spring 3 is pulled by the wire rope 8 during the deformation process, and is less likely to bend sideways, which is beneficial to extending the service life of the shock-absorbing spring 3.

[0027] Furthermore, top blocks 5 are fixedly connected at the four corners of the top of the I-shaped plate 4, the I-shaped plate 4 is engaged with the smart car through the top blocks 5, and the smart car is movably connected to the chassis 1 through the I-shaped plate 4. The top blocks 5 enable the I-shaped plate 4 to be combined with the upper part of the smart car except the chassis 1, thereby realizing floating shock absorption of the upper part of the smart car.

[0028] Furthermore, the top end of the steel wire rope 8 is fixedly connected to the middle part of the bottom end of the I-shaped plate 4, and the bottom end of the steel wire rope 8 is fixedly connected to the middle part of the first screw rod 11. In addition to adjusting the tension of the shock-absorbing spring 3, the steel wire rope 8 can also stabilize the I-shaped plate 4, so that the I-shaped plate 4 maintains better stability in the process of driving the upper part of the smart car to float.

[0029] Furthermore, a cavity 13 is provided inside the sleeve 9, and the steel wire rope 8 is movably connected to the sleeve 9. The cavity 13 is used to receive the steel wire rope 8 wound up by the first screw 11, so that the steel wire rope 8 can be temporarily wound up in the sleeve 9 for standby use.

[0030] Furthermore, the support plate 7 and the rubber pad 15 are movably connected to the chassis 1 through the I-plate 4. The support plate 7 and the rubber pad 15 can extend the bottom end of the I-plate 4 to a position closer to the top of the chassis 1, so that the bottom end of the I-plate 4 can avoid friction with the top end of the sleeve 2 by first contacting the chassis 1, thereby reducing the probability of severe wear of the I-plate 4.

[0031] The method of using this embodiment is as follows: before using the floating shock-absorbing device of the smart car, the device needs to be assembled with the smart car first, so that the wheel hub system of the smart car is respectively installed in the groove 12 of the sleeve box 2, and at the same time, the rest of the smart car except the chassis 1 needs to be connected and fixed with the top block 5 on the I-shaped plate 4. At this time, the smart car is divided into upper and lower halves, so that the upper half of the smart car can be suspended on the chassis 1 of the lower half. When the smart car travels to an uneven road section, the vibration of the wheel will be transmitted to the chassis 1, and the chassis 1 will transmit the vibration to the shock-absorbing spring 3. At this time, the shock-absorbing The spring 3 consumes vibration by deformation, and drives the I-plate 4 to float up and down, so that the vibration of the upper part of the smart car is reduced. At the same time, when the shock absorbing device starts to be used, the torsion bar 10 can be twisted to drive the first screw 11 to rotate in the sleeve 9, so that the first screw 11 winds up the wire rope 8, so that the wire rope 8 passes through the sleeve 9 and enters the cavity 13 to be stored. At the same time, the top of the wire rope 8 will pull the I-plate 4 downward, so that the deformable length of the shock absorbing spring 3 changes, so that the tension of the shock absorbing spring 3 is adjusted, so that the device can be adapted to smart cars with different shock absorption requirements.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
