Description

Technical Field

[0001] This utility model relates to the field of electric flatbed cart technology, specifically to an intelligent electric flatbed cart that can be disassembled and repaired without tools. Background Technology

[0002] Electric flatbed trucks are transportation tools powered by batteries and driven by motors for hauling goods or people. Electricity, as an important energy source that is environmentally friendly, clean, and has a high conversion rate, is used to drive the upgrading of transportation tools, promote the low-carbon development of the transportation industry, reduce transportation costs, save energy, and protect the environment. Electric flatbed trucks have advantages such as strong applicability, maneuverability, simple maintenance, convenient repair, and low price. They can flexibly navigate narrow roads and are widely used in short-distance transportation fields such as households, urban and rural areas, individual taxis, factories, mines, sanitation, and community cleaning.

[0003] As disclosed in CN211918666U, an electric flatbed cart safety anti-collision device includes a chassis. A platform is fixedly installed on the top of the chassis, and rollers are fixedly installed on both the left and right sides of the bottom of the chassis. This electric flatbed cart safety anti-collision device features a baffle with a sponge block on its outer surface. When the electric flatbed cart is impacted, the baffle is compressed, causing the mounting block to press against a second spring. This causes the movable block to press against the fixed compartment, achieving primary shock absorption. Furthermore, pulleys are installed at the top and bottom of the fixed compartment, respectively movably connected to the bottom and top of the mounting compartment. Therefore, when the fixed compartment is compressed, the mounting compartment is also compressed, causing the first spring to press against the vertical rod, which in turn causes the locking block to lock the rollers, preventing the electric flatbed cart from being thrown away by the impact force.

[0004] Regarding the above solution: Although the reference document states that when the electric flatbed cart is impacted, the baffle is compressed, which in turn causes the mounting block to press against the second spring, thereby causing the movable block to press against the fixed chamber, achieving the purpose of primary shock absorption, the electric flatbed cart is mostly connected to the components by bolts during assembly. When the electric flatbed cart is damaged internally, the user needs to disassemble and repair it. During the repair process, the repairman needs to use specified tools to remove the bolts before the electric flatbed cart body shell can be disassembled, and then the internal parts of the cart body can be repaired. The disassembly process is quite cumbersome and complicated. Moreover, if the bolts are disassembled and repaired multiple times, the threads inside the threaded holes will wear down, and the bolts are prone to shaking after installation, which will lead to the unstable installation of the cart body shell, thereby reducing the stability of the electric flatbed cart body shell after installation. Utility Model Content

[0005] The purpose of this utility model is to provide an intelligent electric flatbed cart that can be disassembled and repaired without tools, which has the advantage of tool-free disassembly and repair and solves the problems mentioned in the background art.

[0008] Furthermore, as a preferred embodiment of this utility model, the locking mechanism includes a slider disposed in the inner cavity of the second fixed block. A wedge block is fixedly connected to one side of the slider, and one side of the wedge block extends through the inner cavity of the sleeve. A second spring is fixedly connected to one side of the slider, and the other end of the second spring is fixedly connected to the second fixed block. A second sliding groove is provided on both sides of the inner cavity of the second fixed block, and a second guide block is slidably connected to the inner cavity of the second sliding groove. The second guide block is fixedly connected to the slider.

[0009] Furthermore, as a preferred embodiment of this utility model, a handle is fixedly connected to one side of the first fixing block, and the surface of the handle is provided with anti-slip texture.

[0010] Furthermore, as a preferred embodiment of this utility model, each of the four corners of the bottom of the electric flatbed is fixedly connected with a universal wheel, and the four universal wheels are symmetrically distributed.

[0011] Beneficial effects: The technical solution of this application has the following technical effects: This utility model has the advantage of tool-free disassembly and maintenance. In actual use, the elastic component and locking mechanism work together to limit and fix the concave block, thereby fixing the electric flatbed cart shell. By replacing the traditional bolt connection with a snap-fit, the electric flatbed cart shell can be installed, fixed and disassembled without tools, simplifying the disassembly and installation process of the electric flatbed cart shell, thus saving maintenance time. It also avoids the problem of loose bolt installation caused by long-term wear of the threaded hole, which would lead to an unstable installation of the electric flatbed cart shell. This not only extends the service life of the electric flatbed cart shell, but also makes the installation of the electric flatbed cart shell more secure.

[0023] As attached Figure 1 To be continued Figure 7 As shown: This embodiment provides a tool-free disassembly and maintenance intelligent electric flatbed cart, including an electric flatbed cart body 1. The electric flatbed cart body 1 is characterized by: an electric flatbed cart shell 2 fitted onto its surface; two sleeves 8 embedded on the front and rear sides of the electric flatbed cart body 1; a first fixing block 3 disposed within the inner cavity of each sleeve 8; one end of the first fixing block 3 extending to the outer side of the electric flatbed cart shell 2; a first limiting block 4 fixedly connected to the other end of the first fixing block 3; a sliding rod 5 fixedly connected to one side of the first limiting block 4; a concave block 6 fixedly connected to the other end of the sliding rod 5; a sleeve block 7 fitted onto the surface of the sliding rod 5; second fixing blocks 9 fixedly connected to both sides of each sleeve 8; an elastic component 10 disposed on one side of the inner cavity of each sleeve 8; and a locking mechanism 11 disposed within the inner cavity of each second fixing block 9.

[0024] Specifically, the locking mechanism 11 includes a slider 111 disposed in the inner cavity of the second fixing block 9. A wedge block 112 is fixedly connected to one side of the slider 111. One side of the wedge block 112 extends into the inner cavity of the sleeve 8. A second spring 113 is fixedly connected to one side of the slider 111. The other end of the second spring 113 is fixedly connected to the second fixing block 9. A second slide groove 114 is provided on both sides of the inner cavity of the second fixing block 9. A second guide block 115 is slidably connected to the inner cavity of the second slide groove 114. The second guide block 115 is fixedly connected to the slider 111.

[0025] In this embodiment, the locking mechanism 11 is used to fix the concave block 6, and the elastic force of the second spring 113 prevents the concave block 6 from detaching from the inner cavity of the sleeve 8.

[0026] Specifically, the elastic component 10 includes a second limiting block 101 slidably connected to the inner cavity of the sleeve 8. A first spring 102 is fixedly connected to one side of the second limiting block 101, and the other end of the first spring 102 is fixedly connected to the sleeve 8. A first sliding groove 103 is provided on both sides of the inner cavity of the sleeve 8. A first guide block 104 is slidably connected to the inner cavity of the first sliding groove 103, and one side of the first guide block 104 is fixedly connected to the second limiting block 101.

[0027] In this embodiment, the elastic component 10 is used to limit the concave block 6. The elastic force of the first spring 102 allows the concave block 6 to be in close contact with the wedge block 112, preventing the concave block 6 from shaking in the inner cavity of the sleeve 8.

[0028] Specifically, a handle 14 is fixedly connected to one side of the first fixing block 3, and the surface of the handle 14 is provided with anti-slip texture.

[0029] In this embodiment, the handle 14 increases the contact area between the user's palm and the first fixed block 3, ensuring that the user can move the first fixed block 3 stably.

[0030] Specifically, the four corners of the bottom of the electric flatbed trolley body 1 are fixedly connected with casters 15, and the four casters 15 are symmetrically distributed.

[0031] In this embodiment, the universal wheels 15 enable the electric flatbed cart body 1 to move, thereby improving the flexibility of the electric flatbed cart body 1 during use.

[0032] The working principle and usage process of this utility model: When the user needs to disassemble the outer shell 2 of the electric flatbed cart from the surface of the main body 1 of the electric flatbed cart, by pushing the first fixing block 3 inward, when the wedge block 112 contacts the sleeve block 7, the wedge block 112 drives the sleeve block 7 to move on the surface of the sliding rod 5. When the sleeve block 7 contacts the first limiting block 4, since both the surface of the wedge block 112 and the sleeve block 7 are provided with inclined surfaces, when the first fixing block 3 moves, it will cause the wedge block 112 to contact the sleeve block 7. The wedge block 112 is compressed, causing it to move into the inner cavity of the second fixed block 9. The wedge block 112 drives the slider 111 to move, and the slider 111 drives the second guide block 115 to slide in the inner cavity of the second slide groove 114. When the slider 111 moves, it will drive the second spring 113 to compress. When the wedge block 112 is completely inside the inner cavity of the second fixed block 9, the first fixed block 3 continues to push inward, and the rebound force of the second spring 113 drives the wedge block 112 to move into the inner cavity of the sleeve 8. This positions the wedge block 112 between the sleeve block 7 and the first fixed block 3. The first fixed block 3 then moves outward, causing the sliding rod 5 and the concave block 6 to move via the first limiting block 4. This causes the sleeve block 7 to move into the inner cavity of the concave block 6. When the sleeve block 7 reaches and contacts the inner cavity of the concave block 6, the wedge block 112, in contact with the sleeve block 7, is again pushed into the inner cavity of the second fixed block 9 by the squeezing force. The wedge block 112 then drives the slider 111 to move. The slider 111 drives the second guide block 115 to slide in the second slide groove 114. When the slider 111 moves, it will drive the second spring 113 to compress. When the wedge block 112 is fully inserted into the inner cavity of the second fixing block 9 again, the first fixing block 3 continues to move outward, so that the concave block 6 is completely removed from the inner cavity of the sleeve 8. By moving the electric flatcar shell 2 upward, the electric flatcar shell 2 can be disassembled from the surface of the electric flatcar body 1, which is convenient for the maintenance of the electric flatcar body 1.

[0034] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
