Detailed Description
The present invention will be described in detail below with reference to specific embodiments thereof, with reference to the accompanying drawings. As shown in fig. 1, the sleep monitor therapeutic apparatus includes an AGV mechanism 1, a therapeutic head assembly 2, a controller assembly 3, and a lifting driving mechanism 4.
Example 1 AGV mechanism
The following description is directed to the detailed structure of an AGV mechanism by way of example with a pair of drive wheel assemblies. As shown in fig. 2 to 3, the AGV mechanism 1 includes a chassis 11, a driving wheel assembly 13, a plurality of auxiliary wheel assemblies 14, a driver 15 for controlling the driving wheel assembly 13, and a power supply 16 retained on the chassis 11 by a battery stopper (not shown), and the driver 15 is attached to the side of the power supply 16 for making the structure more compact. The support assembly 12 is fixed on the chassis 11 through the support leg 121, and the support leg 121 is provided with a support leg reinforcing rib 123. The middle part of the chassis 11 is of a lower embedding part structure and is mainly matched with a limit driving wheel assembly 13 to realize a hanging function. Specifically, as shown in fig. 4, the driving wheel assembly 13 includes an in-wheel motor 131 with a driving wheel (not numbered), a hub connection plate 132 and a hub support plate 133 for limiting the in-wheel motor 131, which are engaged with each other, a guide member 137 limited on the hub support plate 133, a guide post 136 guided by the guide member 137, the hub connection plate 132 limited in the suspension support plate 124, a spring 135 limited between the hub connection plate 132 and the hub support plate 133, and a cushion 138 limited between the hub connection plate 132 and the guide member 137. The two sides of the lower embedded part are inwards sunken to reserve an installation space for the driving wheel assembly, a suspension support plate 124 is correspondingly arranged on each outer side of the lower embedded part, and the driving wheel assembly 13 is suspended on the suspension support plate 124 through a hub connecting plate 132. When a pair of driving wheel assemblies 13 is arranged, the driving wheel assemblies are usually arranged in a 'middle driving' mode of a vehicle chassis to output forward or backward power, and the sideslip phenomenon caused by forward driving or backward driving is avoided.
In order to be used as a movable base of the multi-stage driving mechanism, the center of the multi-stage driving mechanism is positioned at one side of the chassis 11, and the overturning is avoided in the running process of the AGV mechanism, therefore, a pair of bottom feet (not marked by figures) are respectively arranged at the front side and the rear side of the chassis, and a pair of universal auxiliary wheel assemblies 14 are further respectively arranged at the front side and the rear side of the chassis for improving the running smoothness. The lower support surface of footing is a little higher than the driving surface of auxiliary wheel subassembly 14, and drive wheel subassembly 13 has adopted suspension type structure, and cooperation footing and auxiliary wheel subassembly 14 can effectively cross pothole road surface. When the lower support surface of the footing is used as the driving wheel to elastically contract, the lowest line of the chassis can be lowered, and the applicable road surface depression degree can be artificially limited in the production process. The footing is fixed in the bottom of the chassis through the bolt assembly and can be freely replaced according to the spring damping amplitude of the driving wheel assembly, so that the optimal damping effect is achieved. When the driving wheel assembly on one side sinks into the deep-pit pavement, the auxiliary wheel assembly 14 serves as a rolling support to reduce the running resistance, the footing support is placed on the horizontal plane to further sink, and the driving wheel assembly 13 can easily drive away under the drive of the driving machine, so that overturning is avoided.
Of course, those skilled in the art can also increase the number of driving wheel assemblies 13 and adapt the positions of the feet and the auxiliary wheel assemblies 14 under the design concept of the present invention, for example, two pairs of driving wheel assemblies are provided, the feet are reduced to one pair between the two pairs of driving wheel assemblies, and the auxiliary wheel assemblies are still provided at the outer sides of the two pairs of driving wheel assemblies respectively, which is not shown.
EXAMPLE 2 Multi-stage drive mechanism
Due to the structural limitation of the electric push rod, the load and the stroke distance need to be matched (generally, when the load is larger, the stroke distance is shorter). When the stroke distance exceeds the maximum stroke of a commercially available electric push rod, the electric push rod lifting mechanism needs to be designed into an internal driving type multi-stage lifting mechanism with multi-electric push rod linkage, and if the lifting stage number is N, the hollow shells of the first lifting assembly to the Nth lifting assembly are sequentially arranged from bottom to top and from outside to inside. Although the inside-out arrangement can achieve a similar purpose, in general, a multistage mechanism arranged from the outside to the inside is adopted to ensure the stability of the structure. A driving device (such as an electric push rod) is respectively arranged in the hollow shell of each level of lifting assembly, and the electric push rods of the adjacent lifting assemblies are arranged in a staggered mode so as to maintain the overall balance of the device. In the step-by-step nesting process, a sliding rail and sliding block matching mode is adopted, for example, a sliding rail is arranged in the adjacent lower hollow shell, a sliding block matched with the sliding rail is arranged outside the adjacent upper hollow shell, and the lifting height is set in a mode of matching the length of the sliding rail with the stroke of the push rod. The multi-stage driving mechanism is mainly limited by the arrangement position of the electric push rod by the hollow shell of the minimum one-stage lifting assembly.
As shown in fig. 15 to 16, the multi-stage driving mechanism can realize the stop of the treatment head assembly at any position between the two extreme positions, thereby effectively improving the application range. When the device is not used, the whole mechanism is adjusted to the lowest contraction position, so that the occupied space can be saved.

The fixed end of the linear drive mechanism or the electric push rod mentioned herein is not meant to be completely fixed, and the fixed end is generally assembled in a manner of being hinged with the corresponding component, and a small range of swing is possible under the action of fit error between the components, and the fixation is named only relative to the large-amplitude movement of the movable end.
The term "the stepping motor drives the other support plate to rotate through the direction changing component engaged with the output end of the stepping motor" mainly refers to the "direction changing" in which the driving bevel gear 4382 provided at the output end of the stepping motor 4381 drives the driven bevel gear 4383 engaged with the stepping motor 4381 to convert the horizontal axis torque into the vertical axis torque.
For the whole machine shell with a decorative function, the adaptability adjustment is required according to the actual production, the fractal mode is not unique, and the purposes of protecting the internal structure and facilitating the assembly can be achieved. The arrangement mode of the device has little influence on the actual internal structure of the whole machine, so the description is not carried out.
For convenience of description, the connecting or supporting structures such as bolts, nuts, angle irons, etc. in the drawings are omitted, and those skilled in the art should know that the above-mentioned components are necessarily used in actual production to realize the connection and fixation of the components. The connection mode of the bolt and the nut is only one of the conventional technical means for matching parts in the field.
