Description

Technical Field

[0001] This utility model relates to the field of sunshade technology for mobile robots, and in particular to a sunshade lifting device for a manned mobile robot. Background Technology

[0002] With the deep integration of artificial intelligence and robotics, intelligent manned mobile robots are being used more and more widely in outdoor scenarios. These devices significantly improve the travel convenience for people with mobility impairments, tourists, and users in special situations.

[0003] However, during extended outdoor operation, users' demands for environmental adaptability, such as sun protection, rain and wind protection, are becoming increasingly prominent. Currently, the sunshade devices for intelligent manned mobile robots mainly adopt the following two technical solutions: one is a rigid fixed sunshade, which uses metal or plastic brackets to fix the sunshade cloth to the top of the robot. This structure is simple, but the angle and height are not adjustable. The other is a semi-rigid detachable sunshade structure, which uses modular design to achieve quick assembly and disassembly of sunshade components, but still requires manual adjustment and cannot automatically respond to environmental changes. Therefore, the following technical problems exist.

[0004] 1. Poor adaptability to dynamic environments: The fixed-angle design of traditional sunshades cannot adjust in real time according to changes in the sun's altitude and azimuth angles, resulting in significant blind spots during the morning / afternoon hours, leaving users' faces, legs, and other areas exposed to direct sunlight. In sudden weather events, the fixed structure cannot provide effective protection and may even affect the robot's stability due to excessive wind resistance.

[0005] 2. Insufficient responsiveness to personalized user needs: Different users have different heights, sitting postures, and sunshade preferences. Existing technology lacks height adjustment and angle fine-tuning functions, making it difficult to meet personalized needs. For example, wheelchair users may need a lower sunshade to avoid obstructing their view, while sightseeing bus passengers may want a wider sunshade area.

[0006] Therefore, there is an urgent need to develop a new type of sunshade device to improve the overall user experience of outdoor manned equipment. Utility Model Content

The first connecting frame is connected to the rotating shaft, and the rotating shaft is rotatably connected to the lifting assembly. The rotating motor is located at the top of the rotating shaft and is used to drive the rotating shaft to rotate.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figure 1 As shown in the figure, this utility model provides a sunshade lifting device for a manned mobile robot, which integrates a lifting mechanism 5 and a rotating mechanism 4 to achieve height adjustment and angle rotation of the sunshade 1. The device includes a sunshade 1, a frame, a drive motor 7 and a transmission mechanism 6, a lifting mechanism 5, and a rotating mechanism 4.

[0033] The frame serves as the basic support structure of the device, including a connecting chassis 2 and a fixed bracket 3. The connecting chassis 2 is horizontally positioned to support the drive motor 7 and transmission components; the fixed bracket 3 consists of two sets, symmetrically and vertically fixed to both sides of the connecting chassis 2, and has a guide channel inside for installing the lifting mechanism 5; the rotating mechanism 4 is rotatably connected to the lifting mechanism 5 and is used to drive the sunshade 1 to rotate, thereby adjusting the sunshade angle.

[0034] The sunshade 1 is shaped like an inverted "U" and is made of polycarbonate. The inverted "U" shape can expand the sunshade range and cover the riding area of ​​the manned mobile robot; the polycarbonate material has the characteristics of high temperature resistance, impact resistance, and moderate light transmittance, which can effectively block direct sunlight while ensuring a certain degree of visual transparency.

[0035] The drive motor 7 is fixedly installed at the middle of the connecting chassis 2, and its output end is connected to the lifting mechanism 5 through the transmission mechanism 6 to provide power for the lifting and lowering of the sunshade 1. Specifically, the two sets of transmission mechanisms 6 are symmetrically distributed about the center point of the connecting chassis 2 to ensure balanced force during the lifting and lowering process. Each set of transmission mechanisms 6 includes a drive gear 61, a transmission gear 62, a coupling 63, and a transmission rod 65. The output ends on both sides of the drive motor 7 are respectively connected to one end of the transmission rod 65 through the coupling 63, and the other end of the transmission rod 65 is fixedly connected to the drive gear 61; both the drive gear 61 and the transmission gear 62 are bevel gears, and the outer wall of the drive gear 61 meshes perpendicularly with the transmission gear 62, that is, the axes of the two gears are perpendicular to each other, while the transmission gear 62 is fixedly connected to the bottom end of the lifting mechanism 5.

[0036] To ensure transmission stability, bearing mounts 64 are symmetrically provided at both ends of the upper surface of the connecting chassis 2. The transmission rod 65 passes through the bearing mount 64 and is rotatably connected to it, which can effectively limit the offset of the transmission rod 65 and reduce the stress during rotation.

[0037] The lifting mechanism 5 is installed inside the fixed bracket 3 and is used to adjust the height of the sunshade 1. It includes a first lead screw 51 and a lifting assembly. The first lead screw 51 is vertically installed inside the fixed bracket 3, and its bottom end is fixedly connected to the transmission gear 62 in the transmission mechanism 6. When the transmission gear 62 rotates, it can directly drive the first lead screw 51 to rotate synchronously. The lifting assembly includes a second lead screw 52 and a second connecting frame 53. The outer wall of the second lead screw 52 is provided with a thread that matches the first lead screw 51. The two are slidably connected by the thread. When the first lead screw 51 rotates, the second lead screw 52 can move up and down along its axial direction. The second connecting frame 53 is fixed to one side of the second lead screw 52 and is used to connect the rotating mechanism 4.

[0038] Specifically, the rotating mechanism 4 includes a first connecting frame 41, a rotating shaft 42, and a rotating motor 43. The first connecting frame 41 consists of two sets, symmetrically fixed to both sides of one end of the inner wall of the sunshade 1, with its ends fixedly connected to the rotating shaft 42. The rotating shaft 42 is rotatably connected to the second connecting frame 53. The rotating motor 43 is fixedly installed on the top of the rotating shaft 42 and can drive the rotating shaft 42 to rotate the sunshade 1 synchronously. Both the lifting mechanism 5 and the rotating mechanism 4 are symmetrically distributed about the center point of the connecting chassis 2, which further improves the stability of the device's operation and reduces unilateral jamming.

[0039] The working principle of this utility model is as follows.

[0040] When the height of the sunshade 1 needs to be adjusted, the drive motor 7 starts, and its output end drives the transmission rods 65 on both sides to rotate synchronously through the coupling 63; the transmission rods 65 drive the drive gear 61 to rotate, and the drive gear 61 meshes perpendicularly with the transmission gear 62, thereby driving the first lead screw 51 to rotate; since the second lead screw 52 is connected to the first lead screw 51 by a thread, the rotation of the first lead screw 51 will be converted into the up and down movement of the second lead screw 52 along its axis, thereby driving the rotating mechanism 4 and the sunshade 1 through the second connecting frame 53 to achieve height adjustment.

[0041] Once the sunshade 1 is raised or lowered to the target height, if the shading angle needs to be adjusted, the rotary motor 43 starts to drive the rotary shaft 42 to rotate; the rotary shaft 42 drives the sunshade 1 to rotate synchronously through the first connecting frame 41 until it is adjusted to an angle that matches the sun's position or the user's needs, thus achieving dynamic shading.

[0042] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
