[0002] Mining overhead passenger transport devices, commonly known as "monkey cars," are essential equipment for transporting personnel in modern mines. The monkey car seat mainly consists of a frame, seat pole, and seat plate. When riding, miners have no upper body support and must rely continuously on their lower back and arms to maintain balance and prevent leaning backward. During long journeys, the continuous tension in the lower back muscles easily leads to fatigue and strain, resulting in extremely poor comfort. Furthermore, the lack of a backrest in the monkey car seat reduces miners' safety. Utility Model Content

[0014] To better understand the purpose, structure, and function of this utility model, the following description of a monkey car seat according to the present utility model is provided in further detail with reference to the accompanying drawings.

[0015] like Figures 1 to 5As shown, this utility model discloses a monkey car seat, including a seat body mounted on a seat post 1, and a backrest located on the side of the seat body opposite to the seat post 1. When riding the monkey car seat, miners can lean against the backrest, reducing the continuous tension on their backs, lowering fatigue levels, and improving comfort. Ribs are provided between the bottom surface of the seat body and the seat post 1. The ribs improve the connection stability between the seat body and the seat post 1, prevent damage to the seat body, and extend its service life.

[0016] Specifically, the seat includes a first seat plate 2 mounted on the seat post 1 and a second seat plate 3 mounted on the first seat plate 2 via a buffer device. When miners need to ride the scooter, they need to sit on the second seat plate 3. The buffer device located between the first seat plate 2 and the second seat plate 3 will cushion the impact force when the miner sits down on the second seat plate 3, reducing the impact force on the first seat plate 2 and the seat post 1, and also improving the comfort of the miner sitting on the seat.

[0017] The buffer device includes limiting posts 4 distributed on the bottom surface of the second seat plate 3. The limiting posts 4 are perpendicular to the second seat plate 3, and each limiting post 4 passes through the first seat plate 2 and slides therewith. A first spring 5 is fitted on each limiting post 4 between the first seat plate 2 and the second seat plate 3. The first spring 5 pushes the first seat plate 2 and the second seat plate 3, causing them to separate. The limiting posts 4 limit the movement of the first seat plate 2 and the second seat plate 3, and, together with the first spring 5, provide sufficient buffer space for them. Simultaneously, the limiting posts 4 only allow the second seat plate 3 to move up and down relative to the first seat plate 2, ensuring stability for the miner sitting on the second seat plate 3 relative to the seat rod 1.

[0018] Specifically, an adjustment assembly is provided on the side of the bottom surface of the first seat plate 2 opposite to the seat post 1, and the backrest is mounted on the adjustment assembly. The adjustment assembly includes a transmission device located between the first seat plate 2 and the second seat plate 3, and a limiting assembly is provided on the transmission device. The backrest is rotatably mounted on the limiting assembly. The limiting assembly includes a mounting base 10 on the transmission device, a fixing post 12 at one end of the mounting base 10 opposite to the transmission device, and a baffle 13 at the free end of the fixing post 12. A handle 11 is slidably mounted on the fixing post 12, and a second spring 14 is sleeved on the fixing post 12 between the handle 11 and the baffle 13. A limiting block 17 is provided on the side of the handle 11 facing the transmission device. Two limiting holes 16 are parallel to each other on the backrest for the limiting block 17 to be inserted, and the edges of the limiting holes 16 are chamfered. The handle 11 is a square frame, and the limiting block 17 is located on the side facing the transmission device; the square handle facilitates hand gripping.

[0019] The backrest can be flipped using the aforementioned limiting component. That is, when the miner needs to adjust the backrest angle, they must pull the handle 11 outwards. Moving the handle 11 compresses the second spring 14, causing the inner limiting block 17 to disengage from the limiting hole 16 on the backrest. This releases the radial lock on the backrest, allowing it to rotate freely around the mounting base 10. With the limiting block 17 disengaged, the miner can rotate the backrest downwards 180 degrees. The other limiting hole 16 on the backrest will then align with the limiting block 17. At this point, the miner releases the handle 11. The compressed second spring 14 returns to its original shape, pushing the handle 11 and the limiting block 17 inwards, allowing the limiting block 17 to smoothly insert into the aligned limiting hole 16. Because the edge of the limiting hole 16 is chamfered, even with slight deviations, the second spring 14 guides the limiting block 17 to slide smoothly in, achieving locking. At this point, the backrest is rigidly fixed again, so that miners who do not need to use the backrest can use it, further improving the practicality of the chair.

[0020] Preferably, the transmission device includes a lifting frame 7 disposed on the bottom surface of the first base plate 2, and a gear 8 is rotatably mounted on the lifting frame 7 via a rotating shaft. Traction plates 9 are disposed on both sides of the gear 8 on the rotating shaft, and the free ends of the traction plates 9 are connected via mounting seats 10. A rack 6 is disposed on the bottom surface of the second base plate 3, and the first base plate 2 has a slot for the rack 6 to pass through, and the rack 6 meshes with the gear 8. Figure 2 As shown, when a miner sits on the second seat plate 3, his body weight compresses the first spring 5, causing the second seat plate 3 to move downwards. The rack 6 mounted on the bottom surface of the second seat plate 3 moves downwards synchronously. The gear 8, meshing with the rack 6, rotates under the drive of the rack 6. The rotation of the gear 8 is transmitted through a shaft to the traction plates 9 mounted on both sides of the shaft. The traction plates 9 swing as the gear 8 rotates, making them perpendicular to the first seat plate 2, facilitating the miner's leaning against it.

[0021] When the miner stands up, the second seat plate 3 returns to its original position under the action of the first spring 5, and the rack 6 moves upward, driving the gear 8 to reverse. The gear 8 drives the traction plate 9 to rotate via the shaft, which in turn drives the backrest to rotate until it is parallel to the first seat plate 2. At this time, in conjunction with the limiting component, the miner pulls the handle 11 on the limiting component, causing the limiting component to release the backrest from its position. Then, the miner can rotate the backrest to a position under the first seat plate 2 for easy storage, saving space when not in use.

[0022] A downwardly extending guard plate 18 is provided on the outer contour of the second seat plate 3, and the inner contour of the guard plate 18 is adapted to the outer contour of the first seat plate 2. A first clearance groove 20 is formed at the end of the guard plate 18 near the seat post 1, and a second clearance groove 21 is formed at the position of the guard plate 18 opposite to the first clearance groove 20, allowing the adjustment assembly to pass through. In this embodiment, the guard plate 18 can improve the aesthetics of the seat and further enhance the connection stability between the first seat plate 2 and the second seat plate 3.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, the backrest includes a support plate 15 rotatably mounted on the mounting base 10, and a backrest rod 19 is provided at the end of the support plate 15 away from the mounting base 10. The support plate 15 is triangular. The triangular shape of the support plate 15 is designed so that when the miner gets off the seat, because the miner is detached from the second seat plate 3, the transmission device will drive the backrest to rotate to a parallel state with the first seat plate 2 via the limiting component. At this time, the triangular support plate 15 can prevent the backrest from snagging on the miner's clothing, thus preventing the miner from falling. Furthermore, when the backrest is tucked under the first seat plate 2, the length of the backrest rod 19 is less than the outer contour of the first seat plate 2, thereby preventing the backrest rod 19 from contacting or snagging on clothing when it is tucked in.

[0024] Instructions for use: When the miner needs to use the backrest, the miner can pull the handle 11. The handle 11 causes the limiting block 17 to disengage from the limiting hole 16 into which it is inserted. The handle 11 also compresses the second spring 14 connected to it. After the limiting block 17 is completely disengaged from the limiting hole 16, the backrest, which is directly below the first seat plate 2, is rotated 180 degrees. Then, the handle 11 is released, and the second spring 14 pushes the handle 11 back to its initial position. The limiting block 17 then inserts into the limiting hole 16, which is now aligned with it, thus fixing the backrest in place. Afterward, the miner sits on the second seat plate 3. The second seat plate 3 descends, causing the limiting post 4 to descend as well, compressing the first spring 5. The rack 6 on the bottom surface of the second seat plate 3 also descends, causing the gear 8 meshing with it to rotate. The gear 8 then drives the traction plate 9 and the backrest mounted on the traction plate 9 to rotate via a rotating shaft, causing the backrest to rotate to a perpendicular position to the first seat plate 2 for the miner to lean against.
