[0020] Figure 1 It is a schematic diagram of the structure of the utility model; Figure 2 It is a schematic diagram of the connection between the linkage block and the brake mechanism; Figure 3 is a schematic diagram of the structure of the turntable; Figure 4 The schematic diagram of the connection between the linkage block and the rotating disk is shown in which the spring 9 is removed; Figure 5 Figure 1 is a schematic diagram of the structure of the heavy hammer block. Figures 1 to 5 As shown, a stall protection device for a sightseeing tour bus comprises a weight block 1, a linkage block 2 and a brake mechanism. The weight block 1 is formed by two counterweights 1.1 fixedly connected by a connecting block 1.2. The weight block 1 is clamped on a turntable 3. One side of the connecting block 1.2 protrudes outward. The protrusion of the connecting block 1.2 is connected to a connecting rod 6 through a first pin shaft 5. The connecting rod 6 is connected to a circular ring 8 through a second pin shaft 7. A clamping groove 8.1 is provided on the edge of the circular ring 8. The clamping groove 8.1 clamps the first pin shaft 5. The circular ring 8 is arranged on either side of the turntable 3. The weight block 1 is at least three pieces; the linkage block 2 is annular, a first protrusion 2.1 is arranged on one side of the linkage block 2, and a second protrusion 2.2 is arranged on the other side of the linkage block 2. The first protrusion 2.1 is arranged on the outside of the weight block 1, and the second protrusion 2.2 is connected to the brake mechanism. The linkage block 2 is two pieces, which are respectively arranged on both sides of the turntable 3. The brake mechanism is two sets, and the turntable 3 is fixedly connected to the rotating shaft 4.

[0021] See also Figure 3 and Figure 4 As shown, the weight block 1 of this embodiment is three pieces, and the three weight blocks 1 are connected to the connecting rod 6 through the connecting block 1.2 and the first pin 5. The rotating disk 3 is correspondingly provided with three rectangular through holes 3.1, and the connecting blocks 1.2 of the three weight blocks 1 are respectively arranged in the rectangular through holes 3.1. The ring 8 is provided with three slots 8.1 and three positioning holes 8.2. The positioning holes 8.2 of this embodiment are arc-shaped, and the slots 8.1 are semicircular. The rotating disk 3 is provided with a positioning pin 3.2 that matches the positioning hole 8.2, and a spring 9 is arranged in the rectangular through hole 3.1. The first The first protrusion 2.1 and the second protrusion 2.2 are offset and are not on the same horizontal plane; when the rotation speed of the turntable 3 is too fast, the three weight blocks 1 will be thrown out at the same time, thereby driving the three connecting rods 6 to rotate the ring 8. When the three weight blocks 1 are thrown out, they move to the same height as the first protrusion 2.1 of the linkage block 2, thereby driving the linkage block 2 to rotate, thereby driving the second protrusion 2.2 of the linkage block 2 to rotate, so that the second protrusion 2.2 is disconnected from the brake mechanism, causing the brake mechanism to operate. The outer diameter of the linkage block 2 in this embodiment is equal to the diameter of the turntable 3.

[0022] When the rotation speed of the turntable 3 is normal, the three weight blocks 1 will not be thrown out at the same time, and the ring 8 is provided with three slots 8.1 which respectively form a locking state with the first pin shafts 5 of the three weight blocks 1. Only when the three weight blocks 1 exceed the safe speed at the same time will they be thrown out together to cancel the locking state, and will they drive the three connecting rods 6 to rotate the ring 8; even if one of the weight blocks 1 is passively thrown out due to bumps or collisions, the connection of the connecting rod 6 and the locking state formed by the slot 8.1 and the first pin shaft 5 will not drive the other two weight blocks 1 to be thrown out, thereby ensuring that the linkage block 2 is driven to rotate only when the rotation speed is too fast.

[0023] The brake mechanism includes a brake pad 10, a connecting rod 11 and a compression spring 12. The brake pad 10 is arranged on the outside of the wheel 20. The brake pad 10 is connected to one end of the connecting rod 11 through a third pin shaft 13. The other end of the connecting rod 11 is connected to the inner side of the second protrusion 2.2 of the linkage block 2. A pressure block 14 is arranged at the other end of the connecting rod 11, and a fourth pin shaft 15 is arranged on the pressure block 14. The compression spring 12 is sleeved on the fourth pin shaft 15. In this embodiment, there are two fourth pin shafts 15 and compression springs 12. Both ends of the fourth pin shaft 15 can be limited by pins. The brake pad 10 of this embodiment is arc-shaped. The other end of the connecting rod 11 presses the compression spring 12 and is arranged between the two second protrusions 2.2 of the linkage block 2. The middle part of the connecting rod 11 is connected to the frame through a fifth pin shaft 16. A round hole is arranged in the middle part of the connecting rod 11, and the fifth pin shaft 16 is connected to the frame through the round hole.

[0024] When the linkage block 2 rotates, the two second protrusions 2.2 of the linkage block 2 are disconnected from the connecting rod 11, so that the other end of the connecting rod 11 moves outward under the action of the compression spring 12, thereby driving one end of the connecting rod 11 to move inward, so that the brake pad 10 at one end of the connecting rod 11 contacts the wheel 20, thereby realizing automatic braking.

[0025] A sightseeing tour bus comprises a stall protection device for the sightseeing tour bus, which is particularly suitable for unmanned driving occasions.

[0026] In short, the utility model can automatically brake when the speed of the sightseeing bus is too fast, without manual operation, thus ensuring the safety of driving, and is particularly suitable for unmanned sightseeing buses.
