[0072] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0073] The present application discloses a chassis device 10, which can be used for small and medium-sized single-body mobile equipment, and can be used as a platform for carrying the main functional modules of the equipment, and can assist in driving the main functional modules to move in space. Optionally, the types of the single-body mobile equipment include but are not limited to sweeping robots, food delivery robots, storage robots, air conditioner sub-units, etc.

[0074] Combination Figures 1 to 12 As shown, the chassis device 10 of the disclosed embodiment at least includes a chassis body, a wheel assembly and a suspension assembly. The chassis body is not only a load-bearing platform as the main component of the direct equipment, but also an assembly frame for the wheel assembly and the suspension assembly. The wheel assembly and the suspension assembly are directly or indirectly mounted on the chassis body. The wheel assembly is used as a component of the chassis in contact with the ground, and the chassis moves relative to the ground by rotating or rolling the wheel body. The suspension assembly is a transmission connection component between the chassis body and the wheel assembly, which can transmit the force and torque between the wheel assembly and the chassis body, and can buffer the impact force received by the wheel assembly during the movement, so that the chassis device 10 moves more smoothly.

[0075] The specific configuration of the chassis device 10 of the present application is described in detail below in conjunction with two embodiments.

[0076] Embodiment 1: Chassis device using wheel hub motor drive

[0077] Combination Figures 1 to 3b As shown, the chassis body of the chassis device 10 mainly includes a chassis body 100 and an inner cover shell 200 .

[0078] Specifically, if Figure 1 and 1a As shown, the overall outer contour of the disk body 100 is a box-like structure with the top open upward. The disk body 100 includes a disk bottom plate 110 and a disk side plate 120; wherein the disk bottom plate 110 is a flat plate with a rectangular shape; the number of the disk side plates 120 is 4, which are respectively arranged on the four sides of the disk bottom plate 110 perpendicular to the upper surface of the disk bottom plate 110, and the corresponding side edges of adjacent disk side plates 120 are connected. Here, the disk bottom plate 110 and the disk side plates 120 are surrounded together to form a semi-enclosed form that opens upward, and the opening can be used as a take-in and put-out port for the functional modules of the equipment, and the internal cavity is used as the layout space of the above-mentioned functional modules, and the disk side plates 120 surrounding the peripheral side can play a role in limiting protection.

[0079] Optionally, the tray bottom plate 110 and the tray side plate 120 are integrally formed structures, thereby reducing the gap at the edge where the tray bottom plate 110 and the tray side plate 120 meet, and improving the overall structural strength of the tray body 100. Alternatively, the four tray side plates 120 are integrally formed structures, thereby reducing the gap at the edge where adjacent tray side plates 120 meet.

[0080] And, the pan side plate 120 is fixed to the pan bottom plate 110 by screwing, riveting or welding. Exemplarily, the lower edge of the pan side plate 120 corresponding to the pan bottom plate 110 is bent inward to form an inner folding edge, the inner folding edge is flush with the upper surface of the pan bottom plate 110, and a plurality of first mounting holes are arranged at intervals along the length direction on the inner folding edge, and a plurality of second mounting holes are also arranged at intervals on the corresponding side plate of the pan bottom plate 110, the first mounting holes and the second mounting holes are in one-to-one correspondence, and the mounting screws can be fixedly connected to the first mounting holes and the second mounting holes, so as to realize the fixed assembly of the pan bottom plate 110 and the pan side plate 120.

[0081] In some optional embodiments, the connecting edges of adjacent tray side panels 120 are configured as arc corners or rounded corners, so that the corners formed by adjacent tray side panels 120 can be relatively smooth, which can reduce the impact force with external objects during the movement of the chassis space, thereby extending the service life of the tray body 100. Here, the arc corner or rounded corner is formed by extending along the length direction of the connecting edge.

[0082] Alternatively, the shape of the tray bottom plate 110 may be configured as a circular, oval or other shape, which may be specifically designed according to the type of the single mobile device to which it is applied, and the present application does not limit this. Similarly, after the shape of the tray bottom plate 110 is changed, the number and configuration of the tray side plates 120 may also be adaptively designed to meet the assembly requirements of the tray bottom plate 110 and the tray side plates 120.

[0083] In the embodiment, the chassis body is configured with a wheel body receiving slot 131 and a suspension receiving slot 132. The wheel body receiving slot 131 is mainly used to receive the wheel assembly, and the suspension receiving slot 132 is mainly used to receive the suspension assembly.

[0084] Specifically, combined with Figure 2As shown, there are two wheel body accommodating notches 131, which are symmetrically opened at the left and right sides of the bottom surface of the chassis body to accommodate the driving wheel 310 of a wheel assembly respectively. Here, the wheel body accommodating notches 131 are formed through the thickness direction of the bottom surface of the disc, and the circumferential dimension of the wheel body accommodating notches 131 is slightly larger than the circumferential dimension of the driving wheel 310. Specifically, in this embodiment, the axial direction of the driving wheel 310 is the same direction as the left and right direction of the bottom surface of the disc. Based on this, the lateral (left and right direction) width of the wheel body accommodating notches 131 is greater than the axial length of the driving wheel 310, and the longitudinal (front and back direction) length of the wheel body accommodating notches 131 is greater than the outer diameter length of the driving wheel 310, so that a movable gap can be formed between the wheel body accommodating notches 131 and the driving wheel 310, so as to reduce the occurrence of problems such as collision with the wheel body accommodating notches 131 during the movement of the driving wheel 310 and obstruction of the rotation of the driving wheel 310.

[0085] For example, Figure 2 As shown, the overall shape of the wheel body accommodating slot 131 is approximately rectangular.

[0086] In some other embodiments, the number of suspension accommodating slots 132 is consistent with the number of wheel body accommodating slots 131. For example, the number of the suspension accommodating slots 132 is also 2, which is the same as the aforementioned wheel body accommodating slots 131. Each suspension accommodating slot 132 is arranged adjacent to the corresponding wheel body accommodating slot 131 to facilitate the assembly connection between the suspension assembly and the wheel assembly.

[0087] In this embodiment, the suspension receiving slot 132 is mainly used to receive the cantilever beam 400 of the suspension assembly. Figure 5 The outer contour of the middle cantilever beam 400 is in the shape of a long rod, and the suspension accommodating notch 132 is also adaptively constructed as a long strip notch. Here, the shape and size of the suspension accommodating notch 132 can be designed according to the structural size of the cantilever beam 400, and this application does not limit this.

[0088] Optionally, the groove space of the suspension accommodating notch 132 and the wheel body accommodating notch 131 is connected to accommodate the parts for connecting the wheel assembly and the suspension assembly, such as Figure 1a The second longitudinal end 420 of the cantilever beam 400 and the corresponding axle of the driving wheel 310 can be accommodated therein.

[0089] Combination Figure 1 and 1aAs shown, the inner cover 200 is arranged on the top surface side of the disk body 100, where the top surface side refers to the upper surface side of the disk bottom plate 110. Here, the inner cover 200 is used to cover the driving wheel 310 located in the wheel body receiving slot 131, and / or the suspension assembly located in the suspension receiving slot 132; thereby, the driving wheel 310, the suspension assembly and other components can be separated from the layout space enclosed by the disk body 100, reducing the structural interference between the equipment functional module and the wheel assembly and the suspension assembly.

[0090] In some embodiments, in combination Figure 3a and 3b As shown, the inner housing 200 includes a first housing portion 210 and / or a second housing portion 220, wherein the first housing portion 210 is used to cover the drive wheel 310 and the wheel body receiving slot 131, and the second housing portion 220 is used to cover the suspension assembly and the suspension receiving slot 132. It should be understood that the first housing portion 210 covers part or all of the drive wheel 310 and the wheel body receiving slot 131, and the second housing portion 220 covers part or all of the suspension assembly and the suspension receiving slot 132.

[0091] Optionally, the overall outer contour of the driving wheel 310 is in the form of a flat wheel body with a circular cross section, and the upper half of the wheel body is located in the wheel body accommodating notch 131 and the upper space thereof. Correspondingly, the first housing portion 210 is constructed in the form of a shell with a semicircular cross section, and a semicircular first housing cavity is formed inside the shell to accommodate the driving wheel 310. Here, the inner diameter of the first housing portion 210 is slightly larger than the outer diameter of the driving wheel 310, so that a sufficient movable gap is formed between the inner shell surface of the first housing portion 210 and the driving wheel 310 to ensure the smooth rotation of the driving wheel 310.

[0092] Alternatively, the suspension accommodating slot 132 in the foregoing embodiment is an elongated slot, and accordingly, the second cover shell portion 220 is constructed as an elongated shell, within which a second cover shell cavity of an elongated rectangle is formed for accommodating suspension components such as the cantilever beam 400.

[0093] In some optional embodiments, the first casing portion 210 and the second casing portion 220 are an integrally formed structure, and there is no structural gap between the two.

[0094] Optionally, the inner cover shell 200 can be fixed to the disk body 100 by screwing, riveting, etc.

[0095] In some other embodiments, the wheel assembly mainly includes a driving wheel 310 and a driving motor 320. The driving wheel 310 is electrically connected to the driving motor 320 so that the driving wheel 310 can be controlled to rotate or stop rotating.

[0096] The type of drive motor 320 used in this embodiment belongs to the wheel hub motor. This type of drive motor 320 is built into the drive wheel 310, which has the advantages of saving transmission parts, simplifying the overall structure, and diversifying the drive mode. In this way, the drive wheel 310 integrated with the drive motor 320 can be accommodated in the wheel body receiving slot 131 as a whole, and the connection structure design between it and the suspension component is simpler, such as only through Figure 4 A wheel axle can realize the connection between the wheel assembly and the suspension assembly, and the wheel axle here is the motor main shaft extending out of the drive motor 320.

[0097] Optionally, the hub motor is a type of motor disclosed in the prior art, so its specific assembly form with the drive wheel 310 can refer to the assembly scheme disclosed in the relevant technology. It is not the main improvement point of the present application, so it will not be described here.

[0098] In an embodiment, Figure 3a and 3c As shown, a wheel axle limiting groove 221 is formed on the second housing portion 220 of the inner housing 200 , and the wheel axle limiting groove 221 can be used to accommodate the wheel axle 330 of the driving wheel 310 and play a role in limiting the movement of the wheel axle 330 .

[0099] Exemplary, combined Figure 3c As shown, the axle limiting groove 221 is formed by extending downward from the middle of one end of the second cover shell close to the driving wheel 310, and a partial shaft section of the wheel axle 330 extends into the axle limiting groove 221. The wheel axle limiting groove 221 can enable the wheel axle 330 to move in the up and down directions in its groove, and block the wheel axle 330 from moving in the front and back directions, so that when the driving wheel 310 encounters uneven ground, it can still move up and down and maintain contact with the ground, and can also determine the relative position of the wheel axle 330 and the second cover shell part 220 (with respect to the front and back directions).

[0100] Optionally, in the vertical direction, the top of the wheel axle limiting groove 221 is constructed as an arc shape, so that when the wheel axle 330 is at the top of the groove, the two can contact relatively smoothly, thereby ensuring that the wheel axle 330 can rotate normally at the top of the groove.

[0101] In some other optional embodiments, the suspension assembly mainly includes a cantilever beam 400 and an elastic member 500. The cantilever beam 400 is used to movably connect the driving wheel 310 and the chassis body to realize the transmission assembly of the two; the elastic member 500 is used to elastically connect the cantilever beam 400 and the chassis body, which can provide elastic tension to the cantilever beam 400 so that the cantilever beam 400 can be maintained at a set position, especially when the cantilever beam 400 moves up and down with the driving wheel 310 when passing through uneven ground, the cantilever beam 400 and the driving wheel 310 can be reset in time under the elastic force.

[0102] Specifically, if Figure 5 As shown, the cantilever beam 400 is in the shape of a long rod as a whole, and has a first longitudinal end 410 and a second longitudinal end 420. The first longitudinal end 410 of the cantilever beam 400 is pivotally connected to the chassis body, and the second longitudinal end 420 is pivotally connected to the axle 330 of the driving wheel 310, and the pivoting surfaces of both are located on a vertical plane. In this way, when passing through an uneven ground, the second longitudinal end 420 of the cantilever beam 400 rotates relative to the axle 330 during the up and down movement of the axle 330, and the connection between the second longitudinal end 420 and the axle 330 is always maintained; at the same time, the first longitudinal end 410 of the cantilever beam 400 also rotates relative to the chassis body during the up and down movement of the axle 330, thereby adapting to the overall height change of the cantilever beam 400.

[0103] Optionally, the cantilever beam 400 is a straight-line beam, a broken-line beam, or an arc-line beam.

[0104] In some embodiments, a cantilever pivot seat 140 is disposed at a position of the inner housing 200 corresponding to the first longitudinal end 410, such as Figure 3b and 3d Accordingly, the first longitudinal end portion 410 of the cantilever beam 400 is provided with a pivot shaft 411, as Figure 5 The pivot shaft 411 and the cantilever pivot seat 140 can form a pivot fit.

[0105] In an embodiment, the cantilever pivot seat 140 is disposed on an inner side surface of the second housing portion 220 of the inner housing 200 .

[0106] In some other embodiments, Figure 5 , 5a As shown in FIGS. 5b and 5b, the second longitudinal end 420 of the cantilever beam 400 is formed with an axial groove 421, and the motor shaft (wheel shaft 330) of the drive motor 320 is clamped in the axial groove 421. Here, the motor shaft can rotate around its own axis in the axial groove 421, so that the second longitudinal end 420 is pivotally connected to the drive wheel 310. In addition, the chassis device 10 also has a thrust plate, which is arranged on the side of the motor shaft away from the drive wheel 310. The thrust plate and the second longitudinal end 420 can form a stop in the axial direction, thereby preventing the drive wheel 310 and the motor shaft from being separated in the axial direction away from the second longitudinal end 420.

[0107] Exemplarily, the thrust plate is an annular plate, and the outer diameter of the annular plate is larger than the groove diameter of the shaft groove 421 to play a stopping role.

[0108] Combination Figure 1As shown, the first elastic end 510 of the elastic member 500 is connected to the chassis body, and the second elastic end 520 is connected to the position of the cantilever beam 400 away from the first longitudinal end 410, and is configured to at least apply an elastic force of upward stretching to the cantilever beam 400. In this way, the cantilever beam 400 can be reset upward under the elastic force after sinking with the driving wheel 310.

[0109] In some optional embodiments, an elastic connection seat is provided on the inner cover shell 200, and the first elastic end 510 of the elastic member 500 is connected to the elastic connection seat.

[0110] For example, Figure 1 and 1a As shown, a hanging rod 230 extending outward to one side of the second cover shell part 220 is provided on the inner cover shell 200, and a hanging hole is formed at the outer end portion of the hanging rod 230. The hanging rod 230 can be used as the aforementioned elastic connecting seat; the first elastic end 510 of the elastic member 500 is constructed as a hook structure, and the hook is hooked with the hanging hole of the hanging rod 230.

[0111] In some alternative embodiments, Figure 5 As shown, the cantilever beam 400 has a support column 430 that is convexly formed upward, and the second elastic end 520 of the elastic member 500 is connected to the support column 430. Here, the shortest straight-line distance between the support column 430 and the hook rod 230 needs to meet the requirement that: after the two elastic ends of the elastic member 500 are respectively connected to the hook rod 230 and the support column 430, the elastic member 500 is in a stretched and tightened state.

[0112] Exemplarily, a hanging hole is configured at the free end of the support column 430 , and correspondingly, the second elastic end 520 of the elastic member 500 is configured as a hook structure, and the hook is hooked with the hanging hole of the support column 430 .

[0113] In addition, combined Figure 3a As shown, a column groove 240 is also provided on the second housing portion 220 of the inner housing 200, and the column groove 240 can be used to allow the support column 430 of the cantilever beam 400 to extend out of the inner housing 200, so as to facilitate connection with the elastic member 500. Optionally, the column groove 240 runs through the thickness direction of the inner housing 200 and extends a certain length in the longitudinal direction of the second housing portion 220, so that a swing space margin in the longitudinal direction of the second housing portion 220 can be reserved during the up and down movement of the support column 430 with the cantilever beam 400, thereby avoiding the column groove 240 from causing obstruction to the support column 430.

[0114] In the above embodiment, the vertical height of the elastic connection seat is higher than the vertical height of the second elastic end 520 (support column 430) of the elastic member 500. Figure 1As shown, the spring has at least an upward elastic force component in the vertical direction. Optionally, the elastic deformation direction (elastic force direction) of the elastic member 500 is in the vertical direction or in an oblique direction that is at an angle to the vertical direction.

[0115] Optional, such as Figure 6 As shown, the elastic member 500 is a spring, an elastic rib, or the like.

[0116] Embodiment 2: Chassis device using wheel-side motor drive

[0117] Combination Figures 7 to 10 As shown, the chassis body of the chassis device 10 mainly includes a chassis body 100 and an inner cover shell 200. Here, the design of the chassis body 100 and the inner cover shell 200 can refer to the technical solution or technical concept disclosed in the above embodiment (I), and will not be repeated here.

[0118] And, the wheel assembly of the chassis device 10 mainly includes a driving wheel 310 and a driving motor 320. The driving wheel 310 is electrically connected to the driving motor 320 so that the driving wheel 310 can be rotated or stopped in a controlled manner. Different from the above embodiment (I), the type of driving motor 320 used in this embodiment belongs to a wheel-side motor. This type of driving motor 320 is arranged on the outside of the driving wheel 310, specifically, it is coaxially or non-coaxially connected to one side of the driving wheel 310 and the two can move synchronously. This type of wheel-side motor has the advantages of high efficiency, low energy consumption, and low cost of use.

[0119] Optionally, the wheel-side motor is a type of motor disclosed in the prior art, so its specific assembly form with the drive wheel 310 can refer to the assembly scheme disclosed in the relevant technology. It is not the main improvement point of the present application, so it will not be described here.

[0120] In this embodiment, the suspension assembly mainly includes a cantilever beam 400 and an elastic member 500. The cantilever beam 400 is used to movably connect the drive motor 320 and the chassis body to realize the transmission assembly of the two; the elastic member 500 is used to elastically connect the cantilever beam 400 and the chassis body, which can provide elastic tension to the cantilever beam 400, so that the cantilever beam 400, the drive motor 320, and the drive wheel 310 can be reset under the elastic force.

[0121] Specifically, if Figures 8 to 10 As shown, the cantilever beam 400 has a first longitudinal end 410 and a second longitudinal end 420. Figure 8 and Fig. 9As shown, the first longitudinal end 410 of the cantilever beam 400 is pivotally connected to the chassis body, and the second longitudinal end 420 is pivotally connected to the drive motor 320, and the pivoting surfaces of both are located on the vertical plane. In this way, when passing through uneven ground, the second longitudinal end 420 of the cantilever beam 400 rotates relative to the drive motor 320 during the up and down movement of the drive motor 320, and the connection between the second longitudinal end 420 and the drive motor 320 is always maintained; at the same time, the first longitudinal end 410 of the cantilever beam 400 also rotates relative to the chassis body during the up and down movement of the drive motor 320, thereby adapting to the overall height change of the cantilever beam 400.

[0122] In some embodiments, the cantilever pivot seat 140 is disposed at an edge position of the disk body 100 corresponding to the suspension receiving slot 132, such as Figure 7b Accordingly, the first longitudinal end portion 410 of the cantilever beam 400 is provided with a pivot shaft 411, as shown Fig.10 As shown, the pivot shaft 411 and the cantilever pivot seat 140 can form a pivot fit. In an embodiment, the covering range of the second housing portion 220 also covers the cantilever pivot seat 140.

[0123] In some other embodiments, the second longitudinal end 420 of the cantilever beam 400 is constructed as a cylindrical structure, the cylinder having a cylindrical space for accommodating the drive motor 320, and the drive motor 320 and the cylinder can rotate relative to each other in the vertical plane; in an embodiment, the outer contour of the drive motor 320 is cylindrical, which can be coaxially inserted in the cylindrical space of the second longitudinal end 420, and the inner wall surface of the cylinder is in smooth contact with the outer surface of the drive motor 320 in the circumferential direction.

[0124] Optionally, in order to reduce the circumferential friction resistance between the second longitudinal end 420 and the drive motor 320, a bearing member may be provided between the second longitudinal end 420 and the drive motor 320. In this solution, the drive motor 320 may serve as a rotating body on the inner side of the bearing member, and the second longitudinal end 420 may serve as a rotating body on the outer side of the bearing member, thereby greatly improving the rotation smoothness through the bearing member.

[0125] In this embodiment, the cylinder of the second longitudinal end 420 of the cantilever beam 400 and the drive motor 320 built into the cylinder will greatly increase the weight on the side of the second longitudinal end 420. Therefore, in order to balance the center of gravity distribution of the cantilever beam 400, the present application also provides a counterweight body 440 at the cantilever beam 400 away from the second longitudinal end 420, and utilizes the counterweight body 440 to increase the specific gravity of the cantilever beam 400 on the side away from the longitudinal end.

[0126] For example, Fig.10As shown, the counterweight body 440 is disposed near the first longitudinal end 410 of the cantilever beam 400. Optionally, the counterweight body 440 is configured as a cylindrical structure similar in appearance to the first longitudinal end 410, so that the weight distribution is more balanced. In addition, in order to reduce the overall weight of the cantilever beam 400, a part of the cantilever beam 400 is in a non-solid form, for example, Fig.10 A hollow groove 450 is provided on the beam body of the cantilever beam 400 between the first longitudinal end 410 and the second longitudinal end 420 . The hollow groove 450 is formed through the beam body so that the weight of this part can be removed.

[0127] Optionally, similar to the above embodiment, the cantilever beam 400 is also provided with a support column 430 and a corresponding column slot 240, and the elastic connection with the chassis body is also achieved by using the support column 430. Here, the design of the support column 430 and its related components can refer to the technical solution or technical concept disclosed in the above embodiment (I), and will not be described in detail here.

[0128] Here, the technical contents not described in detail in this embodiment (II) can refer to the relevant contents of the previous embodiment (I). It should be understood that those skilled in the art can make adaptive improvements to the technical solutions of embodiment (II) based on embodiment (I), which should also be included in the protection scope of this application.

Optionally, the chassis device 10 is the chassis device 10 shown in any of the above embodiments, which is assembled on the slave body 61 and can be used to assist the slave body 61 to move in space.

[0130] Fig.11 In the embodiment, the chassis device 10 is arranged at the bottom of the sub-unit body 61, and the driving wheel 310 of the chassis device 10 is in contact with the ground. The air conditioner sub-unit 60 using the chassis device 10 of the present application not only has low requirements for the processing and assembly accuracy of the chassis suspension components, but also the suspension components and wheel components occupy less space in the vertical height, further reducing the vertical dimension requirements for the air conditioner sub-unit 60, which is conducive to realizing the miniaturization of the air conditioner sub-unit 60.

[0131] In some optional embodiments, the sub-machine body 61 is further provided with one or more functional modules, so as to realize one or more additional functions by using the functional modules, thereby improving the practicality and functional diversity of the sub-machine main body. Optionally, the types of the functional modules include but are not limited to air supply modules, air purification modules, humidity control modules, temperature control modules, and fragrance modules.

[0132] Here, the function of the air supply module is mainly to supply air to the external space in a directional or non-directional manner, for example, the air supply module is a fan component. The function of the air purification module is mainly to purify, filter, and sterilize the air in the external space to reduce the content of pollutants in the external air. For example, the air purification module is a water-washed air module, an ultraviolet germicidal lamp module, an ozone generator module, etc. The humidity control module is mainly used to adjust the moisture content of the air in the external space to keep the air humidity within a comfortable range. For example, the humidity control module is a humidifier, a dehumidifier, etc. The fragrance module is mainly a device for spraying specific air components into the external space. The type of the specific air component can be mosquito repellent gas, air freshener, aromatherapy, etc.

[0133] In some other optional embodiments, the present application also provides an air conditioner 70, such as Fig.12 As shown, the air conditioner 70 includes a main air conditioner 71 and a sub-air conditioner 60. Here, the main air conditioner 71 is configured with a housing compartment 72 for housing the sub-air conditioner 60, and the sub-air conditioner 60 can be moved into / out of the housing compartment 72 in a controlled manner.

[0134] For example, Fig.12 The air conditioner 70 shown in the figure is a floor-standing air conditioner having a rectangular (or cylindrical) body extending vertically, and the lower space of the body can be used as a storage compartment 72 for accommodating the air conditioner sub-unit 60.
