[0002] With the continuous improvement of automobile technology development, people are gradually beginning to pursue an improved driving experience while meeting daily transportation needs. For example, the push-back feeling when the car starts can give the driver a stimulating experience. The push-back feeling is generated by the rapid increase in the car's speed, but the acceleration that the human body can withstand is limited. The instantaneous maximum acceleration of existing vehicles is approximately the acceleration of gravity. If you want to experience a push-back feeling with higher acceleration, you need to further improve the power system. In actual situations, considering the cost of vehicle manufacturing and the safety of personnel, it is impossible to calculate an acceptable acceleration value through a real-person test drive, resulting in a certain bottleneck in how to reasonably set the starting acceleration of the car.

DETAILED DESCRIPTION

[0029] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] like Figure 1-Figure 3As shown, an acceleration track includes an acceleration rail 1, a deceleration rail 2 and a reverse power rail 3 which are horizontally arranged and sequentially connected, and a conveyor belt 4 extending along the guide rail direction is respectively provided on the acceleration rail 1, the deceleration rail 2 and the reverse power rail 3, and the conveyor belt 4 is annular, and each conveyor belt 4 independently completes the conveying work, that is, the conveyor belt 4 on the acceleration rail 1 forms a ring-shaped conveying within the length of the acceleration rail 1, and the conveyor belt 4 on the deceleration rail 2 forms a ring-shaped conveying within the length of the deceleration rail 2, and the reverse power rail 3 is the same.

[0031] The conveyor belt 4 of the acceleration rail 1 is driven to rotate by the first driving member 5, and the conveyor belt 4 of the reverse power rail 3 is driven to rotate by the second driving member 6. The acceleration rail 1 is the initial end, used for acceleration, and the reverse power rail 3 is the end end, used for providing reverse power to help decelerate and stop.

[0032] A push plate device 7 is also slidably connected to the acceleration guide rail 1, and the push plate device 7 is fixedly connected to the conveyor belt 4 of the acceleration guide rail 1; each conveyor belt 4 is in frictional contact with a simulation car 8 in the automobile push-back feeling simulation system.

[0033] The thrust device is fixed on the conveyor belt 4, and the thrust device is driven by the rapid movement of the conveyor belt 4. The thrust is fully applied to the simulated car 8, so that the simulated car 8 sprints quickly, achieving the effect of simulating the push-back feeling of a car. This power only provides the simulated car 8 with instant acceleration, and the simulated car 8 relies on inertia to maintain the running speed in the later stage.

[0034] Two pulleys 9 are arranged on the acceleration rail 1, the deceleration rail 2 and the reverse power rail 3, and both ends of each conveyor belt 4 are sleeved on the pulleys 9. Considering that the center distance between the master and slave wheels is large and the instantaneous speed requirement of the equipment is relatively high, a synchronous wheel mechanism is preferably used. That is, the pulleys 9 are all synchronous wheels, and the conveyor belts 4 are all synchronous belts. This mechanism has the advantages of constant transmission ratio, stable transmission, low noise, high efficiency, etc.

[0035] When the simulated trolley 8 starts from the initial position instantly, it quickly rushes to the middle deceleration rail 2, and the friction between the conveyor belt 4 and the simulated trolley 8 slows down the running speed of the simulated trolley 8, so that it runs to the reverse power rail 3. Due to the different weights of the experiencers riding in the simulated trolley 8, the speed of the simulated trolley 8 will also be different under the action of inertia. At this time, the reverse power rail 3 driving the second driving member 6 plays the role of bringing the simulated trolley 8 to the specified position.

[0036] When the simulated trolley 8 reaches the end position and the experiencer gets off, the simulated trolley 8 needs to be sent back to the initial position. At this time, the deceleration guide rail 2 and the reverse power guide rail 3 become the power part of the return trip. The motor drives the synchronous wheel, the synchronous wheel drives the synchronous belt, and then the friction between the synchronous belt and the simulated trolley 8 drives the simulated trolley 8 back to the initial position.

[0037] The acceleration track is mainly used to experience the feeling of pushing the car back, so the track is preferably in a straight line, that is, the acceleration guide rail 1, the deceleration guide rail 2 and the reverse power guide rail 3 are in a straight line.

[0038] In order to have a better experience effect, the length of the acceleration track is often longer, and the middle deceleration guide rail 2 is mainly used for transition. Therefore, the length of the conveyor belt 4 located in the middle deceleration guide rail 2 can be set shorter. In the preferred embodiment of the utility model, the conveyor belts 4 of the acceleration guide rail 1 and the reverse power guide rail 3 extend from the starting end to the end of the corresponding guide rail; the conveyor belt 4 of the deceleration guide rail 2 is located in the middle of the deceleration guide rail 2.

[0039] The push plate device 7 can be but is not limited to the following structure:

[0040] It includes a base 701, a push plate 702 and a first roller group 703. The base 701 is fixedly connected to the conveyor belt 4 of the acceleration guide rail 1. The push plate 702 is fixed to the top of the base 701. The acceleration guide rail 1 includes a driving plate 10 arranged parallel to the conveyor belt 4. The first roller group 703 includes a plurality of vertical limit rollers 7031 in rolling contact with the driving plate 10 and horizontal limit rollers 7032 in rolling contact with the side of the acceleration guide rail 1. Figure 6 and Figure 7 As shown, the base 701 is bent in a U shape, the push plate 702 is used to push the simulated trolley 8, the base 701 is used to transmit the conveying power of the conveyor belt 4 to the simulated trolley 8 through the push plate 702, the vertical limit roller 7031 is used to limit the vertical direction of the push plate device 7, and the horizontal limit roller 7032 is used to limit the horizontal direction (width direction) of the push plate device 7. When receiving the power output by the first driving member 5, the push plate 702 accelerates to push out the simulated trolley 8 to realize the movement of the simulated trolley 8. After the simulated trolley 8 is sent out, the first driving member 5 rotates in the opposite direction to drive the push plate device 7 to slowly return to the starting position.

[0041] The utility model also proposes a car push-back feeling simulation system, which can simulate 1.2 times the free fall acceleration of the car and experience the instantaneous acceleration feeling. The system includes a simulation car 8 and the above-mentioned acceleration track, the simulation car 8 includes a frame 801 and a seat 802 fixed on the frame 801, a brush 803 and a second roller group 804, the frame 801 and the guide rail of the acceleration track are slidably matched, the second roller group 804 and the guide rail of the acceleration track are in rolling contact, and the brush 803 and the conveyor belt 4 are in contact and friction. Through the combination of the two matching modes of sliding match and rolling contact, the simulation car 8 can run stably, and at the same time, the friction between the simulation car 8 and the frame 801 is reduced, and the friction noise is reduced.

[0042] like Figure 1-Figure 4As shown, the acceleration guide rail 1, the deceleration guide rail 2 and the reverse power guide rail 3 all include a frame 11 and a guide beam fixed to the frame 11, the starting end and the end of the frame 11 are fixed with pulleys 9, the conveyor belt 4 is sleeved on the two pulleys 9, and the guide beam cooperates with the frame 801 and the second roller group 804. That is, the guide beam is in sliding cooperation with the frame 801 and in rolling cooperation with the second roller group 804. The frame 11 serves as a supporting structure, and the remaining components are arranged on the frame 11.

[0043] For the acceleration rail 1, if Figure 4 and Figure 5 As described above, a longitudinal profile 12 is fixed to one side of the frame 11, and the pulleys 9 are installed at both ends of the longitudinal profile 12. After the conveyor belt 4 is installed, the longitudinal profile 12 is located between the upper and lower layers of the conveyor belt 4, which can play a certain supporting and protective role on the conveyor belt 4. Figure 7 As shown, the driving plate 10 is installed on the top of the longitudinal profile 12, the vertical limiting roller 7031 contacts the upper and lower surfaces of the driving plate 10, and the horizontal limiting roller 7032 contacts the side of the longitudinal profile 12.

[0044] The deceleration guide rail 2 and the reverse power guide rail 3 are similar to the acceleration guide rail 1 , except that the push plate device 7 is not provided on the deceleration guide rail 2 and the reverse power guide rail 3 , and the driving plate 10 is not required.

[0045] In a preferred embodiment, each conveyor belt 4 is provided with burrs on its surface, and the contact between the burrs and the brush 803 is utilized to increase the friction between the two. Figure 8 and Fig. 9 As shown, the brushes 803 of the simulated trolley 8 are arranged on both sides and extend downward, and correspondingly, the conveyor belt 4 is located on one side of the guide beam, and the height of the conveyor belt 4 is lower than the height of the guide beam. By adjusting the height of the brush 803 up and down, the tightness of the brush 803 and the bristles on the conveyor belt 4 can be changed to control the magnitude of the friction force.

[0046] The guide beam includes a round tube 13 and a guide plate 14 located on the top of the round tube 13. The frame 801 is provided with a slider 805 that is in sliding contact with the guide plate 14. The second roller set 804 is in rolling contact with the outer circumference of the round tube 13. Fig. 9 As shown, the second roller group 804 includes a plurality of rollers arranged in a staggered manner along the axial direction of the frame 801, and the contact surfaces of the rollers and the circular tube 13 are arranged in a circumferential array along the axial projection. That is, the second roller group 804 surrounds the circular tube 13, and can not only roll with the circular tube 13, but also play a role in supporting the simulation trolley 8, thereby reducing the sliding friction between the slider 805 and the guide plate 14. The slider 805 is mainly used to limit the circumferential position of the simulation trolley 8 to prevent the simulation trolley 8 from tipping over.

[0047] There are two ways of matching the slider 805 with the guide plate 14. The first way is as follows: Figure 8 As shown, the bottom of the slider 805 is provided with a slide groove that cooperates with the guide plate 14. The second method is as follows Fig. 9 As shown, the slider 805 contacts the top of the guide plate 14 through the stud 15, and a third roller group 16 is set at the bottom of the slider 805 to roll in contact with the side of the guide plate 14 to ensure the straight-line travel of the simulated car 8. In comparison, the second matching method has smaller friction and higher movement stability, and the height of the stud 15 can be adjusted according to actual conditions.
