Description

Technical Field

[0001] This utility model relates to the field of stair-climbing vehicle technology, specifically to a seat-type stair-climbing vehicle with a walking mechanism and track connection structure. Background Technology

[0002] The stair-climbing vehicle is a convenient means of transportation for people, especially the elderly, to go up and down stairs. In particular, in some old residential areas where space is limited and it is not convenient to install shaft elevators, the stair-climbing vehicle fills this gap and opens up a new solution to the difficulty of going upstairs in old residential areas.

[0003] Currently, the most common elevators on the market include villa elevators, stairwell elevators, chairlifts, and stair-climbing trolleys. Most use a rack and pinion system for power, where the gears are mounted on an electric motor and the rack is mounted on a track. The motor rotates, and the gears mesh with the rack along the track. Another type uses a screw system, where the electric motor is mounted at one end of the track, the screw is mounted to the motor, and the nut is mounted to the stair-climbing trolley body. The motor starts the screw, which rotates, and the stair-climbing trolley with the nut moves along the track. The running wheels of rack and pinion (stairwell elevators) are often small gourd-shaped, positioned vertically and horizontally on a circular steel pipe track. This type of rail elevator is very sensitive to noise and vibration during operation due to the rack and pinion system, which can cause environmental pollution in enclosed stairwells. For screw-type stair-climbing trolleys, the length of the screw is a significant challenge, as an excessively long screw can cause vibration and affect the operation of the stairwell elevator. Utility Model Content

[0004] The purpose of this utility model is to provide a walking device and track connection structure for a seat-type stair-climbing vehicle. The drive shaft drives the belt shaft or drive gear to rotate, and the connecting belt and toothed straight belt respectively pull the stair-climbing vehicle to move up and down in the stairwell. The U-shaped concave wheel restricts the movement of the square and round track assembly, thereby reducing the noise generated during the up and down movement of the stair-climbing vehicle and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a walking mechanism and track connection structure for a seat-type stair-climbing vehicle, comprising:

[0006] Upstairs carriage and circular track assembly;

[0007] The square and round track assembly includes an upper rail, a lower rail, and a track connecting plate. The two ends of the track connecting plate are connected to the upper rail and the lower rail, respectively. Both the upper rail and the lower rail include a track square tube and a track round tube. The track round tube is welded to the outside of the track square tube. The two ends of the track connecting plate are welded to the weld joints of the track round tube and the track square tube, respectively.

[0008] The outer side of the stair-climbing car is equipped with a walking device upright plate, and a power shaft is installed inside the stair-climbing car. One end of the power shaft passes through the walking device upright plate and is respectively equipped with a belt reel and an auxiliary belt reel. Three U-shaped concave wheels are arranged in a row on the upper and lower sides of the outer side of the walking device upright plate. The U-shaped concave wheels are respectively engaged with the rail tubes on the upper and lower rails. Connecting belts and connecting auxiliary belts are respectively fixedly wound on the belt reel and the auxiliary belt reel. The ends of the connecting belts and connecting auxiliary belts away from the power shaft are connected to the rail connecting plate through fixing bolts.

[0009] Preferably, a first guard plate is installed on the power shaft, and the first guard plate is located at both ends of the winding shaft and the auxiliary belt shaft.

[0010] Preferably, a U-shaped concave wheel shaft is fixed on the upright plate of the walking device, and the U-shaped concave wheel is rotatably connected to the outside of the U-shaped concave wheel shaft.

[0011] Preferably, a power gear is mounted on the power shaft, and a toothed straight belt is provided on the outer side of the power gear. The two ends of the toothed straight belt are fixedly connected to the track connecting plate by fixing bolts. One side of the toothed straight belt meshes with the power gear. Two sets of rollers are mounted on the vertical plate of the walking device. The rollers are arranged in the same direction as the U-shaped concave wheel and are located on both sides of the power gear. The rollers are connected to the smooth surface of the toothed straight belt for transmission.

[0012] Preferably, the power shaft is provided with two sets of second guard plates, which are located on both sides of the power gear.

[0013] Preferably, a safety stop is fixed at the upper vertical edge of the walking device upright plate, and the safety stop fits against the outer side of the upper rail.

[0014] Preferably, a connecting block is fixed to one side of the walker upright plate that is attached to the stair-climbing vehicle car, and the connecting block is embedded on the outside of the stair-climbing vehicle car.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention avoids the rigid contact between traditional gears and racks, which generates noise due to friction, by connecting the winding belt and toothed straight belt to the winding shaft and power gear respectively through soft connections. At the same time, the stair-climbing car contacts the circular tubes in the upper and lower rails through U-shaped concave wheels installed on the vertical plate of the walker. This not only improves the stability of the connection between the stair-climbing car and the square and round rail components, but also reduces noise, making the stair-climbing car run more stably.

[0017] This invention utilizes the flexibility of the coiled belt and toothed straight belt structure to avoid bending caused by gravity due to the distance, thus not affecting the operation of the upstairs carriage. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] like Figure 1-4 As shown

[0031] A walking mechanism and track connection structure for a seat-type stair-climbing vehicle, comprising:

[0032] Upstairs carriage 1 and square / circular track assembly;

[0033] The square and round track assembly includes an upper rail 2, a lower rail 3 and a track connecting plate 4. The two ends of the track connecting plate 4 are connected to the upper rail 2 and the lower rail 3 respectively. Both the upper rail 2 and the lower rail 3 include a track square tube 5 and a track round tube 6. The track round tube 6 is welded to the outside of the track square tube 5. The two ends of the track connecting plate 4 are welded to the welding points of the track round tube 6 and the track square tube 5 respectively.

[0034] like Figure 8 As shown, the processing of the square and round track assembly is as follows: the bottom side of a square track tube 5 of a set length is welded to the upper grooved plane end of the grooved track connecting plate 4. The upper end of the outer circle of the track tube 6 is welded to the welding point of the track tube 5 and the track connecting plate 4 to form the upper rail 2. Conversely, the upper plane side of the track tube 5 is welded to the lower inner plane of the groove of the track connecting plate 4. The lower end of the outer circle of the track tube 6 is welded to the welding point of the upper plane of the track tube 5 and the track connecting plate 4 to form the lower rail 3. The upper rail 2 and the lower rail 3 are connected by the track connecting plate 4.

[0035] The outer side of the stair-climbing car 1 is equipped with a walking device upright plate 7. The stair-climbing car 1 is equipped with a power shaft 8. One end of the power shaft 8 passes through the walking device upright plate 7 and is respectively equipped with a winding belt shaft 9 and an auxiliary belt shaft 10. Three U-shaped concave wheels 11 are arranged in a row on the upper and lower sides of the outer side of the walking device upright plate 7. The U-shaped concave wheels 11 are respectively engaged with the track tubes 6 on the upper rail 2 and the lower rail 3. Connecting winding belts 12 and connecting auxiliary belts 13 are respectively fixedly wound on the winding belt shaft 9 and the auxiliary belt shaft 10. The ends of the connecting winding belts 12 and the connecting auxiliary belts 13 away from the power shaft 8 are connected to the track connecting plate 4 through fixing bolts 14. The fixing bolts 14 are fixed on the top track connecting plate 4 of the square and round track assembly.

[0036] In use, the stair-climbing carriage 1 is brought into contact with the U-shaped concave wheels 11 on the walking plate 7 and the track tubes 6 on the upper rail 2 and lower rail 3 respectively. The drive equipment inside the stair-climbing carriage 1 drives the power shaft 8 to rotate. Then, the power shaft 8 drives the winding shaft 9 and the auxiliary belt shaft 10 to rotate synchronously. Then, the winding shaft 9 and the auxiliary belt shaft 10 wind up the connecting winding belt 12 and the connecting auxiliary belt 13, so that the stair-climbing carriage 1 moves upward on the square and round track assembly. At the same time, the six sets of U-shaped concave wheels 11 are divided into two rows to ensure the stable operation of the stair-climbing carriage. When going downstairs, the power shaft 8 rotates in the opposite direction, so that the stair-climbing carriage moves down on the square and round track assembly.

[0037] Among them, such as Figure 4 As shown:

[0038] A first guard plate 15 is installed on the power shaft 8. The first guard plate 15 is located at both ends of the winding shaft 9 and the auxiliary belt shaft 10. By setting the first guard plate 15 at both ends of the winding shaft 9 and the auxiliary belt shaft 10, it can not only isolate the connecting winding belt 12 and the connecting auxiliary belt 13, but also prevent the connecting winding belt 12 and the connecting auxiliary belt 13 from detaching from the winding shaft 9 and the auxiliary belt shaft 10.

[0039] Furthermore, such as Figure 3-4 As shown:

[0040] A U-shaped concave wheel shaft 16 is fixed on the upright plate 7 of the walking device. A U-shaped concave wheel 11 is rotatably connected to the outside of the U-shaped concave wheel shaft 16. The U-shaped concave wheel shaft 16 facilitates the installation of the U-shaped concave wheel 11, ensuring stability between the U-shaped concave wheel 11 and the upright plate 7 of the walking device. The U-shaped concave wheel 11 is rotatably connected to the U-shaped concave wheel shaft 16, enhancing its stability. The U-shaped concave wheel 11 is engaged with the track tube 6 to maintain stability during the up-and-down movement of the stair-climbing car 1.

[0041] Example 2

[0042] like Figure 5-7 As shown, a walking mechanism and track connection structure for a seat-type mobility stair-climbing vehicle includes:

[0043] Upstairs carriage 1 and square / circular track assembly;

[0044] The square and round track assembly includes an upper rail 2, a lower rail 3 and a track connecting plate 4. The two ends of the track connecting plate 4 are connected to the upper rail 2 and the lower rail 3 respectively. Both the upper rail 2 and the lower rail 3 include a track square tube 5 and a track round tube 6. The track round tube 6 is welded to the outside of the track square tube 5. The two ends of the track connecting plate 4 are welded to the welding points of the track round tube 6 and the track square tube 5 respectively.

[0045] The outer side of the stair-climbing car 1 is equipped with a walking device upright plate 7. The stair-climbing car 1 is equipped with a power shaft 8, and a power gear 17 is installed on the power shaft 8. A toothed straight belt 18 is installed on the outer side of the power gear 17. The two ends of the toothed straight belt 18 are fixedly connected to the track connecting plate 4 by fixing bolts 14. One side of the toothed straight belt 18 meshes with the power gear 17. Two sets of rollers 19 are installed on the walking device upright plate 7. The rollers 19 are arranged in the same direction as the U-shaped concave wheel 11 and are located on both sides of the power gear 17. The rollers 19 are connected to the smooth surface of the toothed straight belt 18. The two ends of the fixing bolts 14 are located on the track connecting plate 4 at the upper and lower ends of the square and round track assembly, respectively.

[0046] When the equipment is running, the power shaft 8 drives the power gear 17 to rotate. Then, the rotation of the power gear 17 moves on the toothed straight belt 18, causing the upper carriage 1 to climb up and down on the upper rail 2 and the lower rail 3.

[0047] It is worth noting that, such as Figure 7 As shown:

[0048] Two sets of second guard plates 20 are provided on the power shaft 8. The second guard plates 20 are located on both sides of the power gear 17. The second guard plates 20 are provided to facilitate the limiting protection of both sides of the power gear 17, preventing the toothed straight belt 18 from separating from the power gear 17, causing the upstairs car 1 to lose the limiting structure and fall downward.

[0049] In a further preferred embodiment, such as Figure 3 and Figure 6 As shown:

[0050] A safety stop 21 is fixed at the upper vertical edge of the walking device upright plate 7. The safety stop 21 fits against the outer side of the upper rail 2. The safety performance of the device is improved by the safety stop 21. The contact between the safety stop 21 and the upper rail 2 prevents the U-shaped concave wheel 11 from falling off the track tube 6, which would cause the stair-climbing vehicle to fall off.

[0051] In addition, such as Figure 9 As shown:

[0052] A connecting block 22 is fixed to one side of the walker upright plate 7 that is attached to the stair-climbing car 1. The connecting block 22 is embedded on the outside of the stair-climbing car 1. The setting of the connecting block 22 can improve the stability of the walker upright plate 7, prevent the walker upright plate 7 from rotating, which would cause changes in the position of the U-shaped concave wheel 11 and the track tube 6, and at the same time ensure the stability of the stair-climbing car 1.

[0053] Using a belt instead of gears and racks as the power source can reduce vibration and tremors caused by mechanical friction during gear and rack operation, making the user more comfortable. It can also reduce noise generated by mechanical friction. Since the elevator is installed in public corridors, the noise can cause great disturbance to residents. Reducing the noise will give residents a better environment.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
