Description

Technical Field

[0001] The utility model relates to the technical field of inspection equipment, in particular to a shock-absorbing buffer wheel mechanism for an inspection robot. Background Technique

[0002] With the wide application of intelligent inspection robots, the robots need to work under various complex and changeable terrain conditions, such as factories, mines, power facilities and other places. During the driving process of traditional robot wheels, especially when encountering potholes or uneven ground, violent vibrations are likely to occur. This not only affects the inspection efficiency and accuracy, but also may damage the electronic components inside the robot. Therefore, there is an urgent need for a buffer wheel structure with good shock-absorbing effect to ensure that the robot can run smoothly under various terrain conditions. The existing shock-absorbing buffer wheel structures are complex in design, high in manufacturing cost, and cumbersome in maintenance and replacement, which is not conducive to large-scale popularization and use. At the same time, some shock-absorbing buffer wheel structures are large in volume and not strong in versatility, and are only applicable to specific robots.

[0003] In view of this, we propose a shock-absorbing buffer wheel mechanism for an inspection robot. Content of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides a shock-absorbing buffer wheel mechanism for an inspection robot.

[0005] The technical solution of the utility model is: including a hub motor, characterized in that: the hub motor mounts the tire on a buffer connecting plate, two buffer guide shafts are locked on the vertical plane of the buffer connecting plate, springs are sleeved outside the buffer guide shafts, and the upper part of the inner cavity of the springs is fixedly connected to a buffer wheel mounting bracket through two other buffer guide shafts.

[0006] As a preferred technical solution, the buffer connecting plate is "L"-shaped.

[0007] As a preferred technical solution, the bottom of the buffer connecting plate fixes the hub motor through a pressing plate.

[0008] As a preferred technical solution, one side of the buffer connecting plate is locked on the slider of a linear guide rail.

[0009] As a preferred technical solution, the top of the buffer wheel mounting bracket is locked on the chassis of the wheeled robot through a connecting flange plate.

[0010] As a preferred technical solution, a baffle is fixed at the lower end of the buffer wheel mounting bracket.

[0011] As a preferred technical solution, a dust cover is installed on the back of the buffer wheel mounting bracket.

[0012] As a preferred technical solution, shielding cases A are provided on both lateral sides of the dust cover horizontally.

[0013] As a preferred technical solution, between two parallel shielding cases A, a shielding case B is symmetrically arranged with the dust cover.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] By sleeving two oppositely arranged buffer guiding shafts with springs, when encountering impacts, vertical buffer structures can be used to digest and buffer, and at the same time, the structure is simple and small in volume. Meanwhile, the buffer connecting plate is convenient to install and disassemble, and can be applied to various forms of robots, with a wide application range. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0021] The (electrical components, electronic components, circuits and power modules, functions, algorithms, methods) involved in the present utility model are merely conventional adaptive applications of the prior art. Therefore, the present utility model is an improvement over the prior art, and its essence lies in the structural improvement rather than the improvement proposed for the (electrical components, electronic components, circuits and power modules, functions, algorithms, methods) themselves. That is to say, although the present utility model involves a bit of (electrical components, electronic components, circuits and power modules, functions, algorithms, methods), it does not include the improvement proposed for the (electrical components, electronic components, circuits and power modules, functions, algorithms, methods) themselves.

[0022] Please refer to Figure 1-2 , the present utility model provides a technical solution:

[0023] An inspection robot shock-absorbing and buffering wheel mechanism, including a hub motor 1.

[0024] The hub motor 1 mounts the tire on the buffer connection plate 7.

[0025] In this embodiment, the bottom of the buffer connection plate 7 fixes the hub motor 1 through a pressure plate 8.

[0026] Two buffer guide shafts 4 are locked on the vertical plane of the buffer connection plate 7. Springs 5 are sleeved around the buffer guide shafts 4. The upper part of the inner cavity of the spring 5 is fixedly connected to the buffer wheel mounting bracket 3 through another two buffer guide shafts 4.

[0027] It is worth further explaining that the number of buffer guide shafts 4 is 4, which are divided into two groups, and 2 in a group are longitudinally arranged opposite to each other.

[0028] It is worth further explaining that when encountering impacts, the vertical buffer structure can be used to digest the buffer, and at the same time, the structure is very simple and small in size, making the movement of the robot smoother.

[0029] In this embodiment, the buffer connection plate 7 is in an "L" shape.

[0030] In this embodiment, one side of the buffer connection plate 7 is locked on the slider of the linear guide rail 6.

[0031] In this embodiment, the top of the buffer wheel mounting bracket 3 is fixedly locked on the chassis of the wheeled robot through a connecting flange 2.

[0032] It is worth further explaining that the connecting flange 2 enables the quick installation of the buffer wheel mounting bracket 3, and this connection design is more convenient for the disassembly, replacement and maintenance of the shock-absorbing and buffering wheel module.

[0033] In this embodiment, a baffle 9 is fixed to the lower end of the buffer wheel mounting bracket 3.

[0034] In this embodiment, a dust cover 10 is mounted on the back surface of the buffer wheel mounting bracket 3.

[0035] In this embodiment, shielding shells A12 are provided on the lateral sides of the dust cover 10.

[0036] In this embodiment, between the two parallel shielding shells A12 and symmetrically arranged with the dust cover 10 is a shielding shell B11.

[0037] It is worth further explaining that the shielding shell B11 and the two parts of the shielding shell A12 are provided to shield and enclose the buffer cavity, preventing sundries such as sediment and rainwater from entering the buffer cavity and affecting the shock absorption effect.
