Detailed Implementation Methods

[0030] The present invention will be further described below with reference to the accompanying drawings:

[0031] Example 1:

[0032] like Figures 1 to 4 and Figure 9 and Figure 10 As shown, an adult support that can be connected to a pushable device includes a connecting frame 1 that can be detachably connected to the pushable device 100, which is a stroller, wheelchair, tricycle, suitcase, or other wheeled pushable vehicle. The rear end of the connecting frame 1 is connected to a swing frame 2 that can swing left and right relative to it. The rear end of the swing frame 2 is connected to a tray assembly 3. The tray assembly 3 is provided with at least one drive wheel 4 and at least one driven wheel 5 that can change the direction of travel. The upper surface of the tray assembly 3 is provided with a standing area 31 that allows an adult to stand when holding the push handle 101 of the pushable device 100. The tray assembly 3 is also provided with a drive mechanism 6 that can drive the drive wheel 4 to rotate. In use, the connecting frame 1 is connected to the pushable device 100. The user can stand in the standing area 31 of the bracket assembly 3, hold the push handle 101 of the pushable device 100, and then activate the drive mechanism 6. The drive mechanism 6 drives the power wheel 4 to rotate, thereby providing forward driving force, and the pushable device 100 is also driven forward. The user can push pushable devices such as strollers, wheelchairs, tricycles, and even suitcases without having to walk, saving time and effort and making it fun. The swing frame 2 and the connecting frame 1 can swing relative to each other, so that the adult bracket can also turn and change direction when needed, allowing the user to use it smoothly. In this embodiment, there are two driven wheels 5 and two power wheels 4.

[0033] like Figure 1 As shown, the connecting frame 1 includes a fixed base 11, on which a left connecting rod 12 and a right connecting rod 13 are connected. The swing frame 2 is connected to the fixed base 11. The front ends of the left connecting rod 12 and the right connecting rod 13 are provided with connecting positions 14 for connecting to the pushable equipment 100. In this embodiment, the connecting position 14 is a connecting hole, allowing the user to pass a webbing through the connecting hole and tie it to the pushable equipment 100. Of course, the connecting position 14 can also be a hook structure, allowing it to be hung on pushable equipment such as a stroller.

[0034] like Figure 1As shown, the left connecting rod 12 and the right connecting rod 13, or one of them, are rotatably connected to the fixed base 11, and the angle between them can be adjusted so that the left connecting rod 12 and the right connecting rod 13 can adapt to the connection position of the pushable device 100. When the connection position on the pushable device 100 is wider, it opens a little; when the connection position on the pushable device 100 is narrower, it closes a little, ensuring that the adult bracket can be used with pushable devices 100 of different sizes.

[0035] like Figure 2 and Figure 3 As shown, the fixed base 11 has a first hook hole 15 at its rear end, and the swing frame 2 has a hook ring 7 at its front end. The hook ring 7 can connect or disconnect the swing frame 2 from the connecting frame 1. The hook ring 7 can be opened or closed. When the hook ring 7 is opened and passes through the first hook hole 15, it connects the connecting frame 1 and the swing frame 2 together. At this time, the hook ring 7 closes again to ensure that the connecting frame 1 and the swing frame 2 are securely connected. When it is necessary to disconnect the connecting frame 1 and the swing frame 2, the hook ring 7 is opened and the frame is removed from the first hook hole 15. The hook ring 7 connects the connecting frame 1 and the swing frame 2, allowing the connecting frame 1 and the swing frame 2 to swing freely, facilitating the free turning and reversing of the pushable equipment 100 and the adult bracket.

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, the tray assembly 3 is provided with a connecting seat 32. The rear end of the swing frame 2 is rotatably connected to the connecting seat 32, allowing the swing frame 2 to rotate in a vertical plane. A locking structure 8 is provided between the swing frame 2 and the connecting seat 32 to lock the swing frame 2 and the connecting seat 32 when the swing frame 2 is rotated to a suitable position. Therefore, the tilt angle of the swing frame 2 in the vertical plane can be adjusted so that the connecting frame 1 can adapt to different connection positions of the pushable device 100, thus making the adult bracket have a wide range of applications. For example, if the connection position on the pushable device 100 is high, the swing frame 2 is adjusted to be more tilted; if the connection position on the pushable device 100 is low, the swing frame 2 is adjusted to be more level. After being adjusted to a suitable position, it is locked by the locking mechanism 8.

[0037] like Figure 4As shown, the locking structure 8 includes a plurality of first teeth 81 arranged on both sides of the connecting seat 32 along the circumferential direction. The swing frame 2 includes a swing rod 22. The front end of the swing rod 22 is movably connected to the connecting frame 1. The rear end of the swing rod 22 is fixedly connected to a connecting fork 23 that can elastically deform. The connecting fork 23 is connected to both sides of the connecting seat 32. The inner side of the connecting fork 23 is provided with second teeth 82 that can mesh with the first teeth 81. The locking structure also includes a connecting shaft 83 that passes through the connecting fork 23 and the connecting seat 32. One end of the connecting shaft 83 is fixedly provided with a knob 84, and the other end of the connecting shaft 83 is provided with a nut that can be threaded to it to lock the connecting fork 23 and the connecting seat 32. When the nut is loosened, the swing frame 2 can be rotated so that the connecting fork 23 rotates relative to the connecting seat 32. During the rotation, the connecting fork 23 undergoes a certain deformation, which causes the second tooth 82 and the first tooth 81 to be squeezed apart and re-engaged, thus continuously changing their positions. When the rotation reaches the appropriate position, the nut is tightened, thereby locking the connecting fork 23 and the connecting seat 32, ensuring that the second tooth 82 and the first tooth 81 are firmly engaged.

[0038] like Figure 4 As shown, the connecting fork 23 includes a left fork body 231 connected to the swing rod 22 and a right fork body 232 connected to the swing rod 22. The left fork body 231 and the right fork body 232 can be provided with matching grooves (not shown in the figure) that match the outer side of the swing rod 22. When the matching grooves are engaged with the outer side of the swing rod 22, the left fork body 231 and the right fork body 232 can be connected to the swing rod 22 by connecting structures such as rivets or screws. The left fork 231 and the right fork 232 are combined to form a connecting groove 9 into which the connecting seat 32 can be inserted. The inner sides of the left fork 231 and the right fork 232 are provided with protruding parts 233. The second tooth 82 is provided on the protruding part 233 along the circumferential direction. The connecting seat 32 is provided with a recessed groove 321 that matches the protruding part 233. The first tooth 81 is provided at the bottom of the recessed groove 321. When the left fork 231 and the right fork 232 are connected to the swing rod 22, the protruding part 233 is inserted into the recessed groove 321, so that the first tooth 81 and the second tooth 82 mesh. At the same time, the cooperation between the protruding part 233 and the recessed groove 321 also makes the connecting fork 23 rotate more smoothly relative to the connecting seat 32.

[0039] like Figure 4 As shown, the two sides of the connecting seat 32 are also provided with a plurality of arc-shaped grooves 85 along the circumferential direction. The left fork body 231 and the right fork body 232 are provided with round protrusions 86 that can engage with the arc-shaped grooves 85, thereby further locking and positioning the rotating fork 23 and the connecting seat 32 to ensure a firm fit.

[0040] like Figure 1 and Figure 2As shown, the pallet assembly 3 includes a plate body 33, a standing area 31 is located on the plate body 33, a connecting seat 32 is located at the front end of the plate body 33, the drive mechanism 6 includes a rechargeable battery 61, the plate body 33 is provided with a mounting slot 34 for mounting the battery 61, the drive mechanism 6 also includes a motor (not shown in the figure) powered by the battery 61 and capable of driving the drive wheel 4 to rotate, and the driven wheel 5 is a universal wheel capable of rotating in the horizontal direction. When using the device, the user stands with both feet on the standing area 31, holds the push rod 101 of the pushable device with both hands, and then starts the drive mechanism 6 to move forward easily. When the user operates the push rod 101 to turn, the connecting frame 1 swings relative to the swing frame 2 and pulls the swing frame 2 to turn and change direction.

[0041] Example 2:

[0042] like Figures 5 to 8 As shown, the difference between Example 2 and Example 1 is that:

[0043] The plate 33 has a rotating frame 35 on its lower side, which can rotate relative to it in the horizontal direction. The front end of the rotating frame 35 has the connecting seat 32. A driven wheel axle 36 is horizontally inserted through the rear side of the rotating frame 35. Driven wheels 5 are connected to both ends of the driven wheel axle 36. The plate 33 has a vertical shaft 37, and a bearing 38 is provided between the vertical shaft 37 and the rotating frame 35. In this embodiment, the connecting seat 32 is connected to the rotating frame 35, and the driven wheels 5 are not omnidirectional wheels. The rotating frame 35 is rotatably connected to the plate 33 via the vertical shaft 37. Therefore, when the pushable equipment 100 turns and changes direction, the swing frame 2 will pull the rotating frame 35 to rotate relative to the plate 33. The rotating frame 35 is connected to the driven wheel 5 via the driven wheel shaft 36. So when the rotating frame 35 rotates relative to the plate 33, the rotating frame 35 drives the driven wheel 5 to swing in the horizontal direction to change the direction of travel of the driven wheel 5, thereby changing the direction of travel of the pallet assembly 3.

[0044] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the invention.
