[0001] This utility model relates to the field of exoskeleton trolley technology, specifically an exoskeleton trolley with one-click quick-release wheels. Background Technology

[0002] In today's cargo handling and transportation industry, manual cart pulling faces numerous challenges. In scenarios such as building material handling and large warehouse cargo transfer, traditional manual cart pulling relies on the laborer's own strength, resulting in extremely high labor intensity. Consequently, in scenarios such as logistics distribution and factory material handling, the use of exoskeleton carts is becoming increasingly frequent.

[0003] Existing exoskeleton trolleys cannot quickly install and remove the bottom rollers, making it inconvenient to store the trolley after use. They also occupy a lot of space when not in use, which is inconvenient for workers to carry out construction on site. Therefore, we need an exoskeleton trolley with one-click quick-release wheels.

[0019] like Figures 1-5 As shown, this utility model provides a technical solution: an exoskeleton trolley with one-click quick-release wheels, comprising a vehicle body 1 composed of a support column 2 and a support frame 3. A fixed seat 4 is fixedly installed on the support column 2, and a slider 5 is slidably sleeved on the outer wall of the support column 2. Both the fixed seat 4 and the slider 5 are hinged to the end of the support frame 3. Several sets of support frames 3 are provided, and the sets of support frames 3 are hinged to each other. A front wheel 8 and a rear wheel 9 are provided at the bottom of the support column 2. An installation mechanism 7 is provided on the front wheel 8 and the rear wheel 9. An installation block 6 is fixedly installed on the outer wall of the support column 2. The installation block 6 is hinged to one end of a storage rod 11, and the other end of the storage rod 11 is hinged to the inner wall of a storage block 12. By pulling up the storage block 12, the bottom of the storage rod 11 can be retracted. The storage rod 11 is retracted, allowing the various support frames 3 inside the vehicle body 1 to be folded together towards the center. Since the length of the support column 2 does not change, the overall height of the vehicle body 1 does not change when it is opened or closed. The inner wall of the mounting block 6 is universally connected to one end of the connecting rod 13, and the other end of the connecting rod 13 is hinged to the fixing box 14. The first telescopic rod 15 slides through the inside of the fixing box 14, and the second telescopic rod 16 slides through the inside of the first telescopic rod 15. A handle 17 is fixedly installed at the end of the second telescopic rod 16. By pushing the first telescopic rod 15 into the second telescopic rod 16 and then pushing it to the right side of the fixing box 14, the handle 17 can be retracted.

[0020] In this embodiment, mounting mechanisms 7 are provided on the front wheel 8 and the rear wheel 9. The mounting mechanism 7 can slide inside the circular groove 76 through the locking ball 73, which allows the front wheel 8 to turn the vehicle body 1 in various directions. The locking ball 73 is engaged inside the circular groove 78, which locks the direction of the rear wheel 9 and guides the vehicle body 1. At the same time, pressing the pressing plate 72 releases the locking ball 73, which facilitates the removal of the front wheel 8 and the rear wheel 9 at the bottom to complete the storage of the vehicle body 1. The top of the square post 77 has a square hole 10. The support column 2 has a plug-in post that matches the square hole 10. After the square post 77 on the top of the rear wheel 9 is inserted into the support column 2, the square hole 10 on the top of the square post 77 is restricted by the plug-in post inside the support column 2, so that the rear wheel 9 cannot change its angle and ensures stability.

[0021] The aforementioned mounting mechanism 7 includes a cylinder 75, which is fixedly mounted on the outer wall of the front wheel 8. A circular groove 76 is formed on the cylinder 75, and a retaining ball 73 slides within the circular groove 76, allowing the front wheel 8 to steer the vehicle body 1 in various directions. A square post 77 is fixedly mounted on the rear wheel 9, and a circular groove 78 is formed on the square post 77. A retaining ball 73 engages with the circular groove 78, locking the direction of the rear wheel 9 and guiding the vehicle body 1. A rotating rod 7 is rotatably connected to the inner wall of the support column 2. 1. A pressing plate 72 is fixedly installed on the outer wall of the rotating rod 71. The pressing plate 72 is bent. Pressing the pressing plate 72 can release the retaining ball 73, which is convenient for installing and removing the front wheel 8 and the rear wheel 9 at the bottom. The retaining ball 73 is fixedly installed on the outer wall of the pressing plate 72. The outer wall of the rotating rod 71 is fixedly connected to one end of the torsion spring 74. The other end of the torsion spring 74 is fixedly connected to the inner wall of the support column 2. The elastic force of the torsion spring 74 can cause the rotating rod 71 to drive the pressing plate 72 on the outer wall to reset.

[0022] In this embodiment, when the vehicle body 1 needs to be used, the front wheel 8 is pushed upward to move the cylinder 75 upward to the inside of the support column 2 for installation. At this time, the bottom end of the pressing plate 72 is pressed, causing the pressing plate 72 to rotate the retaining bead 73 on the outer wall to release the limit. Then, the cylinder 75 is pushed upward, and the spring force of the torsion spring 74 causes the rotating rod 71 to reset the pressing plate 72 on the outer wall. Then, the pressing plate 72 drives the retaining bead 73 to engage with the inside of the circular groove 76. The retaining bead 73 slides inside the circular groove 76, allowing the front wheel 8 to enable the vehicle body 1 to turn in all directions. Similarly, when installing the rear wheel 9, the retaining bead 73 engages with the inside of the circular groove 78, enabling the rear wheel 9 to turn in all directions. The rear wheel 9 guides the vehicle body 1. When the vehicle body 1 needs to be stored, the storage block 12 is pulled up to store the storage rod 11 at the bottom. Then, through the hinge between the support frames 3, the entire vehicle body 1 is brought together and stored in the middle. At the same time, the slider 5 drives the support frame 3 on the outer wall to slide down along the support column 2, so that the support frame 3 is at the same height as before it is stored, which facilitates storage. Then, the first telescopic rod 15 is pushed into the second telescopic rod 16, and then pushed to the right side of the fixing box 14 to complete the storage of the handle 17. Finally, the pressing plate 72 is pressed to release the locking ball 73, which facilitates the removal of the front wheel 8 and the rear wheel 9 at the bottom, thus completing the storage of the vehicle body 1.

[0023] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
