DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Example Reference Figures 1 to 9 , is an embodiment of the present invention, comprising an intelligent cart food delivery robot, comprising, The robot 100 includes a moving part 101 at the bottom, two sets of brackets 102 symmetrically arranged on both sides of the moving part 101, three sets of trays 103 equally divided and arranged between the brackets 102 in a vertical direction, and an intelligent interaction part 104 horizontally arranged at the top of the brackets 102; and, The protection unit 200 includes a limiting component 201 fixedly arranged in the tray 103 in the vertical direction, a pushing component 202 inserted in the axial position of the limiting component 201 in the vertical direction, an adapter component 203 rotatably connected to the end of the pushing component 202, and the top of the outer wall of the adapter component 203 abuts against the end of the pushing component 202, a connecting component 204 rotatably connected to the bottom end of the adapter component 203, and four groups of protective components 205 equally divided in annular shapes on the outside of the connecting component 204, and the inner end of the protective component 205 is rotatably connected to the connecting component 204, and the outermost end of the protective component 205 extends upward.

[0029] During use, combine Figure 1 The mobile component 101 is used to provide mobility of the device. At the same time, a storage slot 1011 for additional loading of items is opened in the mobile component 101 to further improve the practicality of the device. Multiple groups of trays 103 are used to carry tableware. The intelligent interactive component 104 is used to collect external information, process information exchange and other issues. Each group of trays 103 has multiple groups of protection units 200, so a group of trays 103 can hold multiple tableware.

[0030] Among them, combined Figure 1 Two groups of large cross grooves 1031, three groups of medium cross grooves 1032 and five groups of small cross grooves 1033 are provided on the tray 103, and all of the three groups are cross-shaped structures and are provided on the tray 103 in a vertical direction. The three groups have the same structure except for the different sizes. The size of the large cross groove 1031 is larger than that of the medium cross groove 1032, and the size of the medium cross groove 1032 is larger than that of the small cross groove 1033. At the same time, a group of protective units 200 with matching sizes are installed in the large cross groove 1031, the medium cross groove 1032 and the small cross groove 1033, and the four groups of protective components 205 on the protective unit 200 are respectively accommodated in the four branches of the cross structure.

[0031] During use, protection units 200 of different specifications can limit and fix tableware of different sizes, further improving the flexibility of the device. Under normal conditions, the protection components 205 are all stored inside the branches of the cross structure of the large cross groove 1031 to reduce the occupied space.

[0032] Among them, combined Figure 3 and Figure 4The limiting component 201 includes a circular base 2011, four groups of limiting plates 2012 equally divided under the base 2011, a limiting slide groove 2013 located between every two groups of limiting plates 2012, a main guide block 2014 with a triangular structure arranged on one side of the end of the limiting plate 2012, and an auxiliary guide block 2015 with a triangular structure arranged on the other side of the end of the limiting plate 2012, and a slot 2016 composed of the long hypotenuse of the main guide block 2014 and the side of the auxiliary guide block 2015, and the slot 2016 is located between the main guide block 2014 and the auxiliary guide block 2015.

[0033] During use, the limiting component 201 is fixedly installed as a whole in the tray 103. Since the slot 2016 includes the long oblique edge of the main guide block 2014, an object sliding along the long oblique edge of the main guide block 2014 will be inserted into the slot 2016. As shown in the figure, the long oblique edge of the auxiliary guide block 2015 is connected to the limiting slide groove 2013, so an object sliding along the long oblique edge of the auxiliary guide block 2015 will slide into the limiting slide groove 2013.

[0034] Among them, combined Figure 3 and Figure 4 The pushing component 202 includes a central axis 2021 inserted in the axial position of the base 2011, a sleeve 2022 fixedly connected to the end of the central axis 2021, and the sleeve 2022 is located in four groups of limiting plates 2012, and four groups of sliders 2023 are equally divided and arranged around the outer wall of the sleeve 2022, and the slider 2023 extends outward to the limiting slide groove 2013 to be slidably connected.

[0035] During use, since the slider 2023 extends into the limiting slide groove 2013 , the slider 2023 is limited by the limiting slide groove 2013 , so the pushing component 202 is affected as a whole and can only slide and move in the vertical direction along the limiting slide groove 2013 .

[0036] Combination Figure 3 and Figure 4 Furthermore, the pushing component 202 also includes a pressure plate 2026 arranged at the top of the central axis 2021, and a retraction spring 2027 sleeved on the central axis 2021, and the two ends of the retraction spring 2027 are respectively connected to the bottom surface of the base 2011 and the top surface of the sleeve 2022. The retraction spring 2027 always pulls the adapter component 203 upward through its own elastic contraction, giving a force for resetting.

[0037] Among them, combined Figure 3 and Figure 4The adapter component 203 includes a rotating shaft 2031 rotatably connected to the sleeve 2022, and the end of the rotating shaft 2031 extends downward to the outside of the sleeve 2022, four groups of slides 2032 are equally divided and arranged around the outer wall of the rotating shaft 2031, and the slides 2032 extend outward to the limiting slide groove 2013, a secondary guide block 2033 with a right-angled triangle structure is arranged at the top of the slide 2032, and the secondary guide block 2033 is inserted into the slot 2025, and an extension shaft 2034 is arranged at the axial center position of the top end of the rotating shaft 2031, and the extension shaft 2034 extends upward to the sleeve 2022.

[0038] During use, combine Figure 3 and Figure 4 Since the slide plate 2032 of the transfer component 203 extends into the limiting slide groove 2013, it is limited by the limiting slide groove 2013 and can only slide in the vertical direction along the limiting slide groove 2013. However, when it is out of the limiting slide groove 2013, it is no longer limited and can perform a circular rotation operation. The oblique side surface of the secondary guide block 2033 abuts against the oblique surface of the tooth 2024. When the slide plate 2032 is limited by the limiting slide groove 2013, the secondary guide block 2033 abuts against the half position of the side of the tooth 2024 and cannot be fully inserted into the slot 2025. When the slide plate 2032 is out of the limit of the limit slide groove 2013, the secondary guide block 2033 will slide along the oblique edge of the tooth 2024 under the pull of the upward contraction of the retraction spring 2027, and then be completely inserted into the slot 2025. The adapter component 203 is rotatably connected to the bottom of the sleeve 2022 through the extension shaft 2034. At the same time, the two are connected together by the extension shaft 2034 and can synchronously perform vertical displacement and sliding. At the same time, an empty groove for installing the extension shaft 2034 is opened inside the sleeve 2022, and the empty groove has a certain buffer space.

[0039] Among them, combined Figure 3 and Figure 4 The connecting component 204 includes a base plate 2041 located below the rotating shaft 2031, four groups of connecting frames 2042 equally arranged on the outer diameter of the base plate 2041, and the inner ends of the four groups of protective components 205 are correspondingly connected to the four groups of connecting frames 2042 for rotation, and a limiting shaft 2043 arranged at the axial position of the base plate 2041, and the limiting shaft 2043 extends upward into the rotating shaft 2031. The connecting component 204 can drive the end of the protective component 205 to move through the connecting frame 2042, and the limiting shaft 2043 enables the connecting component 204 to rotate in a circle while following the vertical movement of the adapter component 203.

[0040] Among them, combined Figure 6The protective component 205 includes an extension rod 2051 whose inner end is rotatably connected to the connecting frame 2042, a sliding frame 2052 symmetrically arranged on both sides of the outer end of the extension rod 2051, two groups of clamps 2053 symmetrically arranged on both sides of the extension rod 2051, two groups of buffer grooves 2054 are transversely opened on the two groups of clamps 2053, and the two groups of sliding frames 2052 extend into the two groups of buffer grooves 2054 to be slidably connected, a connecting rod 2055 transversely fixedly connected to the outer end of the clamp 2053, and a fixed shaft 2056 arranged at the connecting position between the clamp 2053 and the connecting rod 2055, and both sides of the fixed shaft 2056 extend outward to the inner wall of the large cross groove 1031 to be rotatably connected.

[0041] During use, the fixed shaft 2056 limits the protective component 205 as a whole within the large cross groove 1031. When the connecting component 204 moves, the connecting component 204 will drive the end of the extension rod 2051 to move. The extension rod 2051 can be changed to adapt to the length between the connecting component 204 through the sliding connection with the splint 2053. At the same time, the protective component 205 moving upward will rotate as a whole around the fixed shaft 2056 as the axis to form a lever-type structure.

[0042] Further, combined with Figure 6 The protective component 205 also includes a vertical rod 2057 obliquely fixed at the end of the connecting rod 2055, and the vertical rod 2057 extends upward, an abutment rod 2058 is arranged on the inner side of the vertical rod 2057, and multiple groups of damping rods 2059 are fixedly connected to one side of the abutment rod 2058, and one end of the damping rod 2059 extends outward through the vertical rod 2057, and a buffer spring 20510 is correspondingly sleeved on each group of damping rods 2059, and the buffer spring 20510 is located between the vertical rod 2057 and the fixed shaft 2056.

[0043] During use, the abutment rod 2058 can shrink to a certain extent when squeezed through the damping rod 2059 and the buffer spring 20510 between the vertical rod 2057, thereby absorbing the impact force from the outside, further ensuring the stability of clamping tableware, and buffering the inertia force caused by braking. At the same time, a soft tooth structure is opened on the inner side of the fixed shaft 2056, which can increase the friction during clamping and further enhance the limiting effect.

[0044] In summary, when the robot is used for work, the bottom of the tableware is abutted against the pressure plate 2026, and pressure is applied downward to make the pushing component 202 move downward as a whole. At this time, the retraction spring 2027 is stretched outward, and the pushing component 202 moving downward will push the adapter component 203 to move vertically along the limiting slide groove 2013 through the sleeve 2022. During this process, the oblique side surface of the secondary guide block 2033 abuts against the half position of the oblique surface of the tooth 2024. As the adapter component 203 continues to push downward, when the slide plate 2032 is separated from the limit of the limiting slide groove 2013, the retraction spring 2027 contracts upward to pull the adapter component 203, which will cause the secondary guide block 2033 to slide along the oblique side of the tooth 2024, and then be completely inserted into the slot 2025 (such as Figure 7 As shown in FIG. 2 ), at this time, the slot 2025 also overlaps with the card slot 2016 due to the downward movement of the pushing component 202, so the secondary guide block 2033 will slide into the card slot 2016 along the oblique edge of the main guide block 2014. At this time, the pushing component 202 is stopped, and the secondary guide block 2033 outside the adapter component 203 is limited by the card slot 2016 and will remain in the card slot 2016. At this time, the protection unit 200 is in a locked state (as shown in FIG. 2 ). Figure 8 shown); When the push component 202 pushes the adapter component 203 to move downward, the connecting component 204 will also move with it. The moving connecting component 204 pushes the protective component 205 to rotate as a whole around the fixed axis 2056 through the extension rod 2051. The vertical rod 2057 and the abutment rod 2058 at the end of the rotating protective component 205 will abut against the outer wall of the tableware 300. The four groups of protective components 205 move synchronously and can embrace inward from all sides, thereby limiting and fixing the tableware 300 and providing four groups of limiting forces from different directions, thereby effectively preventing the tableware 300 from being displaced due to braking inertia. On the contrary, when it is necessary to remove the tableware 300, it is only necessary to continue pressing the pushing component 202 downwards. At this time, the adapter component 203 moves downwards again under the squeezing of the pushing component 202, disengages from the limit of the card slot 2016, and under the pull of the retraction spring 2027, the secondary guide block 2033 slides into the limiting slide groove 2013 along the oblique edge of the secondary guide block 2015, and the pressing action is released. At this time, the adapter component 203 moving along the limiting slide groove 2013 will drive the connecting component 204 to move upward, and the connecting component 204 moving upward will simultaneously drive the four groups of protective components 205 to expand outwards and retract into the corresponding large cross grooves 1031, and the tableware 300 is no longer limited, so that it can be easily removed. At this time, the protective unit 200 is in an unlocked state (such as Fig. 9 As shown in the figure), locking and unlocking operations are performed in a specific way, which can effectively avoid the problem of looseness caused by external factors, and play an anti-fool function, further ensuring safety in use.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
