[0041] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.
[0042] Combination Figures 1-10 As shown, in some embodiments, the movable chassis includes: a fixed chassis 100, a movable chassis 200, and an elastic support 300. The lower sidewall of the fixed chassis 100 is fitted with fixed casters 110; one side of the movable chassis 200 is rotatably connected to one side of the fixed chassis 100, allowing it to rotate up and down relative to the fixed chassis 100; the lower sidewall of the movable chassis 200 is fitted with floating casters 210; one end of the elastic support 300 is rotatably connected to the upper sidewall of the movable chassis 200; wherein, when the movable chassis is assembled in a movable home appliance, the other end of the elastic support 300 is rotatably connected to the housing 800 of the movable home appliance.
[0043] The movable chassis provided in this embodiment comprises a fixed chassis 100 and a movable chassis 200. The movable chassis 200 is rotatably connected to the fixed chassis 100 and supported by an elastic support 300. Utilizing the cooperation of the fixed casters 110 in the fixed chassis 100 and the floating casters 210 in the movable chassis 200, the movable chassis 200 and the floating casters 210 can move up and down according to changes in terrain when moving in complex terrain environments, forming a more stable support. This better adapts to complex terrain environments, improves the mobility stability of the movable chassis, and reduces costs.
[0044] Optionally, both the fixed plate 100 and the movable plate 200 are rectangular plate-shaped structures. In this way, the rectangular plate-shaped fixed plate 100 and movable plate 200 have relatively regular shapes, a low center of gravity during movement, high stability, and are easy to install other components on the movable chassis.
[0045] Optionally, one long side of the fixed disk 100 is rotatably connected to one long side of the movable disk 200. In this way, rotatably connecting one long side of the fixed disk 100 to one long side of the movable disk 200 can increase the connection area between the fixed disk 100 and the movable disk 200, and improve the connection stability between the fixed disk 100 and the movable disk 200.
[0046] Optionally, one side of the fixed disc 100 and one side of the movable disc 200 are rotatably connected by a hinge 400. This rotatable connection between the fixed disc 100 and the movable disc 200 via the hinge 400 improves the connection stability between them, while also allowing the movable disc 200 to rotate flexibly relative to the fixed disc 100, facilitating the vertical adjustment of the movable disc 200 and the floating caster 210.
[0047] Specifically, one side of the fixed disk 100 and one side of the movable disk 200 are rotatably connected by a hinge. This hinge connection ensures the stability of the connection between the fixed disk 100 and the movable disk 200 while minimizing the space occupied by the hinge, thus reducing the space required on the sides of the fixed disk 100 and the movable disk 200 and facilitating the installation of other components on the fixed disk 100 and the movable disk 200.
[0048] Optionally, the hinge is located on the upper sidewall corresponding to the side areas of the fixed disc 100 and the movable disc 200. This reduces the impact of the hinge's location on the downward movement of the movable disc 200 and lowers the risk of interference between the hinge and the movable disc 200.
[0049] Optionally, two hinges 400 are provided, and one side of the fixed disc 100 and one side of the movable disc 200 are rotatably connected by the two hinges 400. In this way, the stability of the connection between the fixed disc 100 and the movable disc 200 can be further improved, and the risk of the movable disc 200 detaching from the fixed disc 100 can be reduced.
[0050] Optionally, one short side of the fixed disk 100 and one short side of the movable disk 200 are aligned on the same straight line, and the other short side of the fixed disk 100 and the other short side of the movable disk 200 are also aligned on the same straight line. This ensures that the fixed disk 100 and the movable disk 200 have the same width, and the rotatably connected fixed disk 100 and movable disk 200 can form a more regular structure, making the overall structure of the movable chassis more compact.
[0051] Optionally, the two hinges 400 are symmetrically distributed along the center points of the long sides of the fixed disk 100 and the movable disk 200. This makes the connection between the fixed disk 100 and the movable disk 200 more stable.
[0052] For example, mounting holes are made in the side wall area corresponding to the long side of one side of the fixed disc 100, and mounting holes are also made in the side wall area corresponding to the long side of one side of the movable disc 200. By passing screws or other structures through the holes on the hinge 400 and the mounting holes on the fixed disc 100 and the movable disc 200 in sequence, the hinge 400 is mounted on the fixed disc 100 and the movable disc 200, thereby making the fixed disc 100 and the movable disc 200 rotatably connected.
[0053] Optionally, such as Figure 2 As shown, multiple fixed casters 110 are provided, and each fixed caster 110 is respectively located in the corner area of the opposite side of the fixed plate 100 and the movable plate 200, where they are rotatably connected. In this way, by providing multiple fixed casters 110 and positioning them in the corner area of the side of the fixed plate 100 facing away from the movable plate 200, support is provided for the side of the fixed plate 100 facing away from the movable plate 200. The cooperation between the floating casters 210 on the movable plate 200 and the fixed casters 110 further enhances the stability of the movable chassis.
[0054] Optionally, one long side of the fixed plate 100 is rotatably connected to one long side of the movable plate 200, and multiple fixed casters 110 are respectively arranged in the corner area of the other long side of the fixed plate 100. In this way, through the cooperation of multiple fixed casters 110 and multiple floating casters 210, the support range of the movable chassis is increased, and the movement stability of the movable chassis is improved.
[0055] Specifically, there are two fixed casters 110, which are respectively located at the two corners of the other long side of the fixed disc body 100.
[0056] Optionally, two corner areas on the other long side of the fixed disc body 100 are provided with embedding grooves 120, and the fixed caster wheel 110 is embedded in the embedding groove 120 and protrudes from the lower side wall of the fixed disc body 100 along the embedding groove 120. In this way, the installation stability of the fixed caster wheel 110 is improved, making it less likely for the fixed caster wheel 110 to shift.
[0057] Understandably, the fixed caster wheel 110 can rotate horizontally relative to the fixed disc 100, but cannot float vertically. While achieving omnidirectional movement, it provides relatively stable support for the fixed disc 100.
[0058] Optionally, such as Figure 4 and Figure 5 As shown, a bridge-type support 500 is provided on the upper side wall of the movable chassis 200. The bridge-type support 500 is rotatably connected to the upper side wall of the movable chassis 200. Floating casters 210 are connected to the ends of the bridge-type support 500, allowing the floating casters 210 to float up and down with the bridge-type support 500. In this way, by setting the bridge-type support 500 to support the floating casters 210, the floating casters 210 can float up and down relative to the movable chassis 200 under the action of the bridge-type support 500, thereby better adapting to complex terrain environments and further improving the mobility stability of the movable chassis.
[0059] Optionally, the bridge bracket 500 is arranged along the length of the movable plate 200. This increases the support range of the bridge bracket 500, and the floating caster 210 connected to the end of the bridge bracket 500 cooperates with the fixed caster 110 to form a more stable support.
[0060] Optionally, both ends of the bridge bracket 500 are connected to floating casters 210. When one floating caster 210 at one end of the bridge bracket 500 moves downward, the other floating caster 210 at the other end moves upward. Thus, by providing floating casters 210 at both ends of the bridge bracket 500, the two floating casters 210 can float in opposite directions under the action of the bridge bracket 500, allowing the movable chassis to further adapt to complex terrain environments.
[0061] Taking the width direction of the fixed disc 100 as the front-to-back direction and the length direction of the fixed disc 100 as the left-to-right direction, since the long side of the movable disc 200 is rotatably connected to the long side of the fixed disc 100, the movable disc 200 is located on one side of the fixed disc 100 in the width direction, that is, the movable disc 200 is located in front of the fixed disc 100. When encountering uneven terrain in the front-to-back direction, the movable disc 200 can float up and down relative to the fixed disc 100 to adapt to the uneven terrain. The bridge bracket 500 is set along the length direction of the movable disc 200, and floating casters 210 are set at both ends of the bridge bracket 500. When encountering uneven terrain in the left-to-right direction, the bridge bracket 500 can rotate relative to the movable disc 200, and the two ends of the bridge bracket 500 float in the left-to-right direction, causing the two floating casters 210 to float up and down to adapt to the uneven terrain. The floating mechanism of the movable chassis 200 and the bridge support 500 allows the mobile chassis to adapt to uneven terrain environments in all directions, improving the stability of movement.
[0062] Optionally, when the bridge support 500 rotates relative to the movable plate 200, the vertical plane of the bridge support 500 is always parallel to the vertical plane of the long side of the movable plate 200. This ensures that the bridge support 500 remains aligned along the length of the movable plate 200 during rotation, preventing the floating casters 210 connected to both ends of the bridge support 500 from shifting forward or backward, reducing the risk of center of gravity shift in the movable chassis, and improving stability during movement.
[0063] Understandably, when the bridge support 500 rotates relative to the movable plate 200, the projection of the bridge support 500 is always parallel to the long side of the movable plate 200 in the vertical direction.
[0064] Optionally, the two floating casters 210 are respectively located in the two corner areas corresponding to the non-connecting long side of the movable chassis 200. Thus, since the fixed chassis 100 and the movable chassis 200 form a rectangular overall structure, and the fixed casters 110 are located in the two corner areas on the non-connecting long side of the fixed chassis 100, placing the two floating casters 210 in the two corner areas corresponding to the non-connecting long side of the movable chassis 200 improves the stability of the movable chassis. This is because the two fixed casters 110 and the two floating casters 210 are located in the four corner areas of the rectangular overall structure formed by the fixed chassis 100 and the movable chassis 200.
[0065] Understandably, the movable disc 200 has two long sides, one of which is rotatably connected to the long side of the fixed disc 100, and the other long side is the non-connected long side.
[0066] Optionally, the bridge bracket 500 is located on the upper side of the movable plate 200. The two corner areas corresponding to the non-connecting long side of the movable plate 200 are provided with through holes 220. The upper end of the floating caster 210 passes through the through hole 220 and is connected to the end of the bridge bracket 500. The lower end of the floating caster 210 protrudes along the lower side wall of the movable plate 200.
[0067] Optionally, such as Figure 6 As shown, the middle position of the bridge bracket 500 is rotatably connected to the upper side wall of the movable plate 200. Since both ends of the bridge bracket 500 are connected to floating casters 210, to improve the support stability of the bridge bracket 500 and make the supporting force on the two floating casters 210 more even, the middle position of the bridge bracket 500 is rotatably connected to the upper side wall of the movable plate 200, so that the supporting torque on the two floating casters 210 is the same.
[0068] Optionally, the upper side wall of the movable plate 200 is provided with a mounting base 230, and the inner side of the mounting base 230 is provided with an installation space. The lower side wall of the bridge bracket 500 is provided with a connecting ear 510, which extends into the installation space and is rotatably connected to the mounting base 230. In this way, the bridge bracket 500 is rotatably connected to the movable plate 200 through the cooperation of the connecting ear 510 and the mounting base 230, which improves the stability of the rotatable connection between the bridge bracket 500 and the movable plate 200.
[0069] Optionally, the connecting ear 510 is rotatably connected to the mounting base 230 via a connecting shaft 520. The connecting shaft 520 passes sequentially through the mounting base 230 and the connecting ear 510, and its axial direction is parallel to the short side of the movable disc 200. In this way, the mounting base 230 and the connecting ear 510 are rotatably connected via the connecting shaft 520, and the connecting shaft 520 is parallel to the short side of the movable disc 200. This connection, along with the mounting base 230, restricts the forward and backward displacement of the bridge bracket 500, ensuring that when the bridge bracket 500 rotates relative to the movable disc 200, its vertical projection remains parallel to the long side of the movable disc 200.
[0070] Optionally, such as Figure 7 and Figure 8As shown, the elastic support part 300 includes a storage cylinder 310 and a telescopic rod 320. One end of the storage cylinder 310 is rotatably connected to the upper side wall of the movable tray 200, and the other end has a storage opening 311. One end of the telescopic rod 320 is telescopically embedded in the storage cylinder 310 along the storage opening 311. When the movable chassis is assembled in the movable home furnishing device, the other end of the telescopic rod 320 is rotatably connected to the housing 800 of the movable home furnishing device. In this way, the elastic support part 300 is divided into a storage cylinder 310 and a telescopic rod 320. When the movable chassis is assembled in the movable home furnishing device, the elastic support part 300 cooperates with the housing 800 of the movable home furnishing device to support the movable tray 200. When the movable disc 200 floats up and down, the telescopic rod 320 can extend and retract along the storage cylinder 310 as the movable disc 200 floats up and down, thereby changing the length of the elastic support part 300. This allows the elastic support part 300 to support the movable disc 200 while its length changes with the up and down movement of the movable disc 200, reducing the impact of the elastic support part 300 on the up and down movement of the movable disc 200.
[0071] Optionally, the lower end of the storage tube 310 is rotatably connected to the movable plate 200, so that the lower end of the storage tube 310 can rotate in the front-back direction relative to the movable plate 200. The upper end of the storage tube 310 is provided with a storage opening 311. The lower end of the telescopic rod 320 is telescopically embedded in the storage tube 310 along the storage opening 311. The upper end of the telescopic rod 320 is rotatably connected to the housing 800 of the movable home furnishing equipment, so that the telescopic rod 320 can rotate back and forth relative to the housing 800 of the movable home furnishing equipment.
[0072] Optionally, the elastic support 300 further includes a spring 330. The spring 330 is sleeved on the outside of the telescopic rod 320, with one end connected to the storage cylinder 310 and the other end connected to the end of the telescopic rod 320. Thus, the spring 330 provides elastic force or tension to the telescopic rod 320 during its extension and retraction, thereby providing elastic cushioning for the movable disc 200 and achieving a vibration reduction effect. When the movable disc 200 floats upward, the telescopic rod 320 is compressed into the storage cylinder 310. The spring 330 provides elastic force to both the telescopic rod 320 and the storage cylinder 310, preventing the telescopic rod 320 from retracting excessively into the storage cylinder 310 and ensuring the elastic support 300 provides elastic support to the movable disc 200. When the movable disc 200 floats downward, the telescopic rod 320 is stretched out of the storage cylinder 310. The spring 330 can provide tension to the telescopic rod 320 and the storage cylinder 310, preventing the telescopic rod 320 from extending too far out of the storage cylinder 310 and ensuring the elastic support part 300 provides elastic support to the movable disc 200.
[0073] Optionally, two elastic support portions 300 are provided. The lower ends of both elastic support portions 300 are rotatably connected to the upper side wall of the movable plate 200. When the movable chassis is assembled in the movable home appliance, the upper ends of both elastic support portions 300 are rotatably connected to the housing 800 of the movable home appliance. In this way, by providing support for the movable plate 200 with two elastic support portions 300, the support stability of the movable plate 200 is further improved, thereby improving the movement stability of the movable chassis.
[0074] Optionally, the two elastic support parts 300 are symmetrically distributed around the center point of the long side of the movable disk 200. This makes the supporting force on the movable disk 200 more uniform, further improving the support stability of the movable disk 200 and making it less prone to floating and shifting.
[0075] Optionally, such as Figure 9 As shown, the movable chassis also includes a differential drive wheel 600. The differential drive wheel 600 is rotatably mounted on the fixed chassis body 100 and located between the fixed caster wheel 110 and the floating caster wheel 210. Thus, by using the differential drive wheel 600 to drive the movable chassis, and by mounting the differential drive wheel 600 on the fixed chassis body 100, the driving stability of the differential drive wheel 600 is improved. The differential drive wheel 600's location between the fixed caster wheel 110 and the floating caster wheel 210 enhances the moving stability of the movable chassis.
[0076] Optionally, two differential drive wheels 600 are provided, with each wheel located on one of the two short sides of the fixed disc 100. This design, using two differential drive wheels 600 for driving, improves the driving stability of the movable chassis.
[0077] Optionally, a drive motor 700 is provided on the upper sidewall of the fixed chassis 100 in the area corresponding to the two differential drive wheels 600. The drive motor 700 meshes with the corresponding differential drive wheel 600 through a differential gearbox 710. In this way, the drive motor 700 drives the differential gearbox 710 to rotate, thereby driving the differential drive wheel 600 to rotate. The differential gearbox 710 enables the two differential drive wheels 600 to rotate at different speeds, thereby realizing the steering of the movable chassis.
