[0027] Some embodiments of this disclosure will now be described in detail, examples of which are illustrated in the accompanying drawings.

Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0028] The embodiments described in the following examples of this disclosure are not representative of all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0029] This application provides a mobile device. For example... Figure 1 and Figure 2 As shown, the mobile device 100 includes a drive wheel 10 and a base 20. The drive wheel 10 includes a wheel body 101. The base 20 includes a mounting plate 21, on which the drive wheel 10 is mounted, and the wheel body 101 is located on one side of the mounting plate 21. The base 20 also has a receiving groove 22 for accommodating the operating mechanism 200. The bottom surface of the receiving groove 22 is located on the side of the mounting plate 21 facing the wheel body 101; that is, in the height direction of the mobile device 100, the bottom surface of the receiving groove 22 is lower than the mounting plate 21.

[0030] The mobile device provided in this application embodiment has a receiving groove 22 for accommodating the operating structure 200, and the bottom surface of the receiving groove 22 is located on the side of the mounting plate 21 facing the wheel body 101, which can reduce the installation height of the operating mechanism 200. Since the mobile device includes the mobile device, it is beneficial to lower the overall center of gravity of the mobile device, thereby improving the stability of the mobile device when driving and reducing the risk of tilting or tipping over, especially on uneven ground or when making rapid turns. Furthermore, the reduced installation height of the operating mechanism 200 can increase the minimum operating space of the mobile device, enabling the mobile device to perform operations such as picking up and placing in a lower space, making the mobile device suitable for different application scenarios.

[0031] In one embodiment, the bottom surface of the receiving groove 22 is lower than the top height of the wheel body 101. This further reduces the installation height of the operating mechanism 200. The operating mechanism 200 may be a lifting mechanism, or the operating structure 200 may be a robotic arm, or the operating mechanism may include both a lifting mechanism and a robotic arm.

[0032] In one embodiment, such as Figure 2 As shown, the base 20 also includes a side plate 23 and a bottom plate 24. The bottom plate 24 is located on the side of the mounting plate 21 facing the wheel body 101. The side plate 23 is located between the mounting plate 21 and the bottom plate 24, and is connected to both the bottom plate 24 and the mounting plate 21. The distance from the surface of the side plate 23 away from the bottom plate 24 to the bottom plate 24 is a first distance, and the distance from the surface of the mounting plate 21 away from the bottom plate 24 to the bottom plate 24 is a second distance. The first distance is less than or equal to the second distance. That is, when the moving device is in operation, the top surface of the side plate 23 is lower than the top surface of the mounting plate 21, or the bottom surface of the side plate 23 is flush with the top surface of the mounting plate 21. The side plate 23 and the bottom plate 24 together form the receiving groove 22.

[0033] Since the first distance is less than or equal to the second distance, the highest point of the receiving groove 22 does not exceed the mounting plate 21. Under the premise that the depth of the receiving groove 22 is certain, the installation height of the operating mechanism 200 can be reduced to the maximum extent.

[0034] It should be noted that the bottom surface of the base plate 24 away from the mounting plate 21 should not be lower than the bottom of the wheel body 101. Preferably, the surface of the base plate 24 away from the mounting plate 21 is higher than the bottom of the wheel body 101 to avoid obstructing the movement of the mobile device.

[0035] In one embodiment, such as Figure 1 and Figure 2 As shown, the receiving slot 22 includes a first sub-receiving slot 221 and a second sub-receiving slot 222. The first sub-receiving slot 221 is used to receive the operating mechanism 200, and the second sub-receiving slot 222 is used to receive the power supply module 300. The bottom surfaces of both the first sub-receiving slot 221 and the second sub-receiving slot 222 are lower than the mounting plate 21.

[0036] In one embodiment, such as Figure 1 As shown, the moving device 100 includes two drive wheel sets 11, each of the drive wheel sets 11 including at least one drive wheel 10, and the two drive wheel sets 11 are located on opposite sides of the first sub-accommodating groove 221. Figure 1 In the embodiment shown, two drive wheel sets 11 are arranged along the first direction X. There is space between the two drive wheel sets 11 in the first direction X. The first sub-accommodating groove 221 is set between the two drive wheel sets 11 to make full use of this space, making the structure of the mobile device 100 more compact. In addition, the above arrangement can also improve the uniformity of force on the base 20 and improve the stability of the mobile device.

[0037] Furthermore, the height of the second sub-receiving groove 222 is the same as the height of the first sub-receiving groove 221, and the bottom surface of the second sub-receiving groove 222 is on the same plane as the bottom surface of the first sub-receiving groove 221.

[0038] In one embodiment, the receiving slot 22 includes two second sub-receiving slots 222, which are located on opposite sides of the first sub-receiving slot 221. This allows the weight of the power supply module to be evenly distributed on both sides of the first sub-receiving slot 221; since the mobile device includes a moving device, this avoids excessive forward tilting, backward tilting, or side-tipping of the mobile device due to uneven weight distribution on both sides.

[0039] In one embodiment, such as Figure 1 and Figure 2As shown, each drive wheel assembly 11 includes at least two drive wheels 10, and each drive wheel assembly 11 and a second sub-receiving slot 222 are located on the same side of the first sub-receiving slot 221; in the drive wheel assembly 11 and the second sub-receiving slot 222 located on the same side of the first sub-receiving slot 221, the drive wheels 10 of the drive wheel assembly 11 are distributed on opposite sides of the second sub-receiving slot 222. This arrangement fully utilizes the space below the mounting plate 21, making the structure of the mobile device 100 more compact; each drive wheel assembly 11 can share a portion of the weight of the power supply module, making the force on the mobile device 100 more even.

[0040] like Figure 1 As shown, two drive wheel sets 11 are arranged along a first direction X, and the drive wheel set 11 located on the same side of the first sub-receiving groove 221 and the second sub-receiving groove 222 are arranged along a second direction Y. Each drive wheel set 11 includes two drive wheels 10, and the second sub-receiving groove 222 is located between the two drive wheels 10 of the drive wheel set 11. The second direction Y intersects the first direction X. In some embodiments, the second direction Y is perpendicular to the first direction X.

[0041] In other embodiments, the moving device may include only one drive wheel 10, with a receiving groove 22 provided at least on one side of the drive wheel 10. The drive wheel 10 may be a caster wheel.

[0042] Furthermore, the receiving groove 22 may be arranged around the drive wheel 10. The receiving groove 22 may include a plurality of sub-receiving grooves spaced apart around the drive wheel 10, or it may be a closed annular groove.

[0043] Furthermore, the receiving groove 22 includes a first sub-receiving groove for accommodating the operating mechanism and a second sub-receiving groove for accommodating the power supply module. The first and second sub-receiving grooves can be arranged at intervals around the periphery of the drive wheel 10, or they can be connected to form a closed annular groove. Taking the operating mechanism as an example, which includes a lifting mechanism and a robotic arm, the receiving groove 22 may include two first sub-receiving grooves and two second sub-receiving grooves. One first sub-receiving groove can be used to accommodate the lifting mechanism, and the other first sub-receiving groove can be used to accommodate the robotic arm. The first and second sub-receiving grooves can be alternately arranged around the periphery of the drive wheel 10, with the two first sub-receiving grooves facing each other and the two second sub-receiving grooves facing each other. In this way, the operating mechanism and the power supply module surround the drive wheel 10, which can make the force on the moving device 100 more uniform.

[0044] In other embodiments, the mobile device may include three drive wheels, wherein the line connecting the centers of gravity of the three drive wheels forms a triangle. Of course, the mobile device may also include more drive wheels. This application does not limit the number or arrangement of the drive wheels.

[0045] In one embodiment, such as Figure 1As shown, two second sub-receiving slots 222 are symmetrically distributed on both sides of the first sub-receiving slot 221. This layout allows the weight of the power supply module to be evenly distributed on opposite sides of the mobile device 100; since the mobile device includes a mobile unit, it can improve the problem of unbalanced torque caused by external forces or its own forces during the movement of the mobile device, and ensure the stable operation of the mobile device.

[0046] In one embodiment, such as Figure 1 As shown, the first sub-accommodating slot 221 is connected to the second sub-accommodating slot 222. The connected space allows for more flexible installation and connection of components such as operating mechanisms or power supply modules, facilitates wiring, and avoids the need for detours or perforations for wiring due to spatial separation, thus facilitating subsequent maintenance and repair of the wiring.

[0047] In one embodiment, such as Figure 1 As shown, the top of the second sub-accommodating slot 222 has an opening, which makes it easy to remove the power supply module when it needs to be replaced. There is no need to disassemble the moving device 100 or operate from the side of the moving device 100 or other hard-to-reach openings. The power supply module located in the second sub-accommodating slot 222 can be directly accessed through the top opening, which reduces the difficulty of replacing the power supply module.

[0048] In one embodiment, such as Figure 1 As shown, the base 20 further includes a reinforcing plate 25 located within the first sub-receiving groove 221, the reinforcing plate 25 being connected to the side wall of the receiving groove 22. The reinforcing plate 25 can enhance the structural strength of the base 20, reducing the likelihood of deformation or damage to its side wall when the base 20 is subjected to external impact. In some embodiments, the reinforcing plate 25 may be connected to the side wall of the first sub-receiving groove 221. In some embodiments, the base 20 may include multiple reinforcing plates 25.

[0049] In one embodiment, such as Figure 2 and Figure 3 As shown, the drive wheel 10 also includes a steering motor 102, a drive motor 103, and a connecting part 104. The drive motor 103 is connected to the wheel body 101 and drives the wheel body 101 to rotate. The wheel body 101 is connected to the steering motor 102 through the connecting part 104, and the steering motor 102 drives the wheel body 101 to turn through the connecting part 104. When the steering motor 102 receives a steering control command, it outputs torque and transmits the torque to the wheel body 101 through the connecting part 104, enabling the wheel body 101 to change its orientation on the plane and achieve left or right steering. The drive motor 103 can be integrated with the wheel body 101, and the drive motor 103 can directly drive the wheel body 101 to rotate, achieving forward and backward movements.

[0050] In one embodiment, such as Figure 2 and Figure 3 As shown, the steering motor 102 is connected to the mounting plate 21.

[0051] In one embodiment, such as Figure 2 and Figure 3 As shown, the connecting part 104 includes a suspension 1041 and a rocker arm 1042. The suspension 1041 is connected to the steering motor 102, one end of the rocker arm 1042 is connected to the suspension 1041, and the wheel 101 is connected to the rocker arm 1043. The steering motor 102 outputs torque to control the suspension 1041 to rotate, causing the rocker arm 1042 to drive the wheel 101 to rotate.

[0052] In one embodiment, the connecting portion 104 further includes a shock absorber 1043, which is mounted on the suspension 1041 and connected to one end of the swing arm 1042. During operation, the wheels 101 are subjected to impacts from the ground. These impacts can be transmitted to the shock absorber 1043 via the swing arm 1042, preventing the impact force from being directly transmitted to the base of the mobile device and other components.

[0053] This application also provides a mobile chassis component, such as Figure 2 As shown, the mobile chassis assembly includes the aforementioned mobile device 100 and operating mechanism 200, with the operating mechanism 200 installed within the receiving slot 22.

[0054] In one embodiment, the receiving slot 22 includes a first sub-receiving slot 221 for receiving the operating mechanism 200. The end of the operating mechanism 200 is fixed to the base plate 24 of the first sub-receiving slot 221, and its installation position is low. Since the mobile device includes a mobile chassis assembly, the overall center of gravity of the mobile device can be lowered, thereby improving the overall stability of the mobile device.

[0055] In one embodiment, such as Figure 2 As shown, the receiving slot 22 further includes a second sub-receiving slot 222, and the mobile chassis assembly further includes a power supply module 300, which is placed in the second sub-receiving slot 222.

[0056] This application also provides a mobile device, including the aforementioned mobile chassis component.

[0057] In one embodiment, the operating mechanism 200 is a lifting mechanism, and the mobile device may further include a robot body. The operating mechanism 200 is connected to the robot body and is used to drive the robot body to move away from the mobile device 100 and to move closer to the mobile device 100. When the robot body moves towards the mobile device 100, it can reach a lower position height, allowing the robot body to perform operations in low spaces or close to the ground.

[0058] In another embodiment, the operating structure 200 is a robotic arm connected to the base.

[0059] In another embodiment, the mobile device may include both a lifting mechanism and a robotic arm.

[0060] In the above detailed description, reference has been made to the accompanying drawings, which illustrate specific aspects of this disclosure by way of illustration. In this regard, terms indicating direction or positional relationship, such as “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “clockwise,” “counterclockwise,” “axial,” “radial,” and “circumferential,” are used with reference to the orientation of the described figures. Since components of the described device can be positioned in multiple different orientations, directional terms are used for illustrative purposes and not for limitation. It should be understood that other aspects can be utilized and structural or logical changes can be made without departing from the concept of this disclosure. Therefore, the following detailed description should not be considered limiting.

[0061] It should be understood that, unless otherwise specifically indicated, the various exemplary embodiments described herein and features of some embodiments of this disclosure may be combined with each other. As used herein, the term “and / or” includes any one of the relevant listed items and any combination of any two or more; similarly, “at least one of…” includes any one of the relevant listed items and any combination of any two or more.

[0062] It should be understood that, unless otherwise expressly specified and limited, the terms "joining," "attaching," "installing," "connecting," "linking," "fixing," etc., used in the embodiments of this disclosure should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms herein based on the specific circumstances.

[0063] Furthermore, the term "above" as used herein with respect to components, elements, or material layers formed or located "above" a surface may be used to indicate that the component, element, or material layer is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on the surface such that one or more additional components, elements, or layers are arranged between the surface and the component, element, or material layer. However, the term "above" as used with respect to components, elements, or material layers formed or located "above" a surface may also optionally have a specific meaning: that the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, for example, in direct contact with the surface.

[0064] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, the first component, part, region, layer, or section mentioned in the examples may also be referred to as the second component, part, region, layer, or section. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include at least one of that feature. In the description herein, “a plurality” means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0065] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0066] Furthermore, the term “exemplary” is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “exemplary” is not necessarily to be construed as advantageous compared to other aspects or designs. Rather, the use of the term “exemplary” is intended to present the concept in a concrete manner. As used herein, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless otherwise specified or clear from the context, “X applies A or B” is intended to mean any of the natural inclusive arrangements. That is, “X applies A or B” satisfies any of the foregoing instances if X applies A; X applies B; or both X applies A and B. Additionally, unless otherwise specified or clear from the context to refer to the singular form, the articles “a” and “an” as used in this application and the appended claims are generally understood to mean “one or more.”

[0067] Similarly, although this disclosure has been shown and described with respect to one or more implementations, equivalent variations and modifications will occur to those skilled in the art upon reading and understanding the specification and drawings. This disclosure includes all such modifications and variations and is limited only by the scope of the claims. In particular, with respect to the various functions performed by the components described above (e.g., elements, resources, etc.), unless otherwise indicated, the terminology used to describe such components is intended to correspond to any component (functionally equivalent) that performs the specific function of the described component, even if structurally not equivalent to the disclosed structure. Furthermore, although specific features of this disclosure may have been disclosed with respect to only one of several implementations, such features may be combined with one or more other features of other implementations, as may be desired and advantageous to any given or particular application. Moreover, with regard to the terms “comprising,” “owning,” “having,” “having,” or variations thereof as used in the detailed description or claims, such terms are intended to be inclusive in a manner similar to the term “including.”
