Description

Technical Field

[0001] This utility model belongs to the technology of stair climbing machines, specifically relating to a drive wheel set for stair climbing machines. Background Technology

[0002] A stair climber is a new type of tool for carrying goods (or people) up stairs. It uses its own motion actuator to move up and down stairs, thus achieving the purpose of going up and down stairs. The stair climber consists of multiple parts, including a drive wheel set.

[0003] Existing drive wheel assemblies are inconvenient to use on steps of varying heights, thus reducing their applicability and causing inconvenience to users. This phenomenon has become a problem that urgently needs to be solved by those in the field. Utility Model Content

[0004] The purpose of this invention is to provide a drive wheel set for a stair climber, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a drive wheel set for a stair climber, comprising two wheel pieces, the outer surfaces of the two wheel pieces being composed of three interconnected "S" shapes, and three main climbing wheels, a first auxiliary wheel, and a second auxiliary wheel being equally spaced between the two wheel pieces. Each of the main climbing wheel, the first auxiliary wheel, and the second auxiliary wheel has a bolt assembly connected to the wheel piece inside. The arc surface design achieves a low torque effect, thereby enabling it to withstand greater loads and reducing the driving force required by the drive motor. Furthermore, through the coordinated use of the main climbing wheel, the first auxiliary wheel, and the second auxiliary wheel, it can be adapted to different specifications of stair surfaces, including limitations on width, height, and flatness, making stair climbing more stable and safer.

[0006] Furthermore, both of the wheel pieces have mounting grooves on their outer walls, which facilitates alignment during the installation of the drive wheel assembly.

[0007] Furthermore, a reinforcing plate is fixedly connected between the two wheel pieces on the side closer to the main crawling wheel and away from the second auxiliary wheel. Three reinforcing plates are provided and distributed at equal angles. The reinforcing plates are welded to the wheel pieces, which facilitates reinforcement through the reinforcing plates.

[0008] Furthermore, anti-slip and shock-absorbing pads are fixedly connected to the two wheel pieces on the side closer to the second auxiliary wheel and the side farther away from the main climbing wheel. There are three anti-slip and shock-absorbing pads distributed at equal angles, and the anti-slip and shock-absorbing pads are welded to the wheel pieces, which facilitates shock absorption and anti-slip work when in contact with the stair steps.

[0009] Compared with the prior art, the beneficial effects achieved by this utility model are: This utility model,

[0010] (1) By setting up wheel plates, mounting grooves, reinforcing plates, anti-slip and shock-absorbing pads, main climbing wheels, first auxiliary wheels, second auxiliary wheels, and bolt assemblies, the arc surface design achieves the effect of small torque, thereby bearing greater load and reducing the driving force requirement of the drive motor. Furthermore, with the cooperation of the main climbing wheels, first auxiliary wheels, and second auxiliary wheels, it can be used on different specifications of stair surfaces, including width, height, and flatness restrictions, making climbing stairs more stable and safe.

[0014] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0015] Please see Figure 1 This utility model provides a technical solution: a drive wheel set for a stair climber, comprising two wheel pieces 1. The outer surfaces of the two wheel pieces 1 are composed of three interconnected "S" shapes. Three main climbing wheels 5, a first auxiliary wheel 6, and a second auxiliary wheel 7 are arranged at equal angles between the two wheel pieces 1. The main climbing wheels 5, the first auxiliary wheel 6, and the second auxiliary wheel 7 are all provided with bolt assemblies 8 connected to the wheel pieces 1. The arc surface design achieves a low torque effect, thereby bearing a greater load and reducing the driving force required by the drive motor. Furthermore, with the cooperation of the main climbing wheels 5, the first auxiliary wheel 6, and the second auxiliary wheel 7, it can be adapted to different specifications of stair surfaces, including limitations on width, height, and flatness, making stair climbing more stable and safer.

[0016] Furthermore, the outer walls of both wheel pieces 1 are provided with mounting grooves 2, which facilitates the alignment work during the installation of the drive wheel set.

[0017] Furthermore, a reinforcing plate 3 is fixedly connected between the two wheel pieces 1 on the side closer to the main climbing wheel 5 and away from the second auxiliary wheel 7. There are three reinforcing plates 3, which are distributed at equal angles. The reinforcing plates 3 are welded to the wheel pieces 1, which is conducive to reinforcement through the reinforcing plates 3.

[0018] Furthermore, anti-slip and shock-absorbing pads 4 are fixedly connected to the two wheel pieces 1 on the side closer to the second auxiliary wheel 7 and the side away from the main climbing wheel 5. There are three anti-slip and shock-absorbing pads 4, which are distributed at equal angles. The anti-slip and shock-absorbing pads 4 are welded to the wheel pieces 1, which is beneficial for shock absorption and anti-slip work when in contact with the stair steps.

[0019] During use, the three "S" arc surfaces of wheel 1 effectively achieve a low torque effect and can withstand greater loads, thereby reducing the power required to drive the stair climber motor and thus reducing costs. At the same time, during stair climbing, the contact between the main climbing wheel 5, the first auxiliary wheel 6, and the second auxiliary wheel 7 and the stairs allows for use on stairs of different heights, flatness, and widths, thus expanding the applicability. Furthermore, the anti-slip and shock-absorbing pads 4 enhance stability during stair climbing, thereby ensuring safety.
