[0035] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0036] This embodiment provides a cart, such as Figure 1 , Figure 2 and Figure 4 As shown, the cart includes a body 10, which includes a bottom bracket 17. Folding components 11 are hinged on both sides along the width direction of the bottom bracket 17. The folding components 11 can drive the bottom bracket 17 to fold or open along its length direction. When the folding components 11 and the bottom bracket 17 are opened, the body 10 can accommodate items. Folding pieces 12 are provided at both ends along the length direction of the bottom bracket 17. The two sets of folding pieces 12 are pivotally connected to the bottom bracket 17 and can be folded in a direction away from the folding components 11 so that items can be placed on the body 10.

[0037] Folding components 11 are arranged on both sides along the width direction of the bottom bracket 17, and the folding components 11 drive the bottom bracket 17 to fold and unfold, so that the entire body 10 can be folded or unfolded. When the cart needs to be used, the body 10 is unfolded and items can be placed on the body 10. When use is over, the body 10 can be folded for easy storage and transportation. In addition, if the cart needs to be used to transport larger and longer items, the folding pieces 12 at both ends of the bottom bracket 17 along its length direction can be folded in a direction away from the folding components 11. At this time, when placing items, not only is there no restriction on the folding pieces 12 at both ends, but after the folding pieces 12 at both ends are folded in a direction away from the folding components 11, the length of the body 10 can be increased, so that larger and longer items can be placed. After use, the folding pieces 12 can be folded up again. The operation is simple and convenient, and the overall structure of the cart will not be complicated, and the application range is wider.

[0038] It is worth mentioning that in the present embodiment, when using the cart to push some smaller items, it is only necessary to open the body 10. At this time, the folding components 11 and the folding pieces 12 are surrounded by the outer periphery of the bottom bracket 17, and the items are placed on the bottom bracket 17 to ensure that they will not fall from the outer periphery of the bottom bracket 17. When placing longer items, the folding pieces 12 at both ends are folded along the length direction. At this time, when placing the items, the folding pieces 12 can support the items together with the bottom bracket 17, and the folding components 11 on both sides can also ensure that the objects will not fall from the bottom bracket 17, and the use effect is good.

[0039] To simplify the overall structure of the cart, Figure 1 and Figure 2 As shown, at least two support rods 18 are arranged at intervals on both sides of the bottom bracket 17 in the width direction, and the folding assembly 11 is hinged between two adjacent support rods 18 in the length direction of the bottom bracket 17. In this embodiment, two support rods 18 are arranged on both sides of the bottom bracket 17 in the width direction, and both ends of the folding assembly 11 in the length direction of the bottom bracket 17 are hinged to the support rods 18, and the middle part of the folding assembly 11 is hinged to the bottom bracket 17, so that when the folding assembly 11 is stretched or pushed in the length direction of the bottom bracket 17, the folding assembly 11 can drive the bottom bracket 17 to fold or open. In other embodiments, another set of support rods 18 can be arranged at the position where the middle part of the folding assembly 11 is hinged to the bottom bracket 17, so that the folding assembly 11 is hinged between two adjacent support rods 18 in the length direction of the bottom bracket 17, as long as it can ensure that the folding assembly 11 can drive the bottom bracket 17 to fold, no other restrictions are made in this embodiment.

[0040] In addition, in order to facilitate the fixing of the folding member 12, as Figure 1 and Figure 2As shown, a first clamping portion 13 is provided on one side of the support rod 18 away from the folding assembly 11, and the first clamping portion 13 can clamp the folding member 12. When using this cart to transport some smaller items, it is not necessary to put down the folding member 12. Therefore, by providing the first clamping portion 13, the folding member 12 can be fixed when it is not necessary to fold it, ensuring that it will not shake during use, thereby ensuring a good use effect. In addition, in order to prevent the folding member 12 from being worn during the clamping process, the first clamping portion 13 is made of elastic material. In this embodiment, the first clamping portion 13 is a plastic buckle, which has a good clamping effect and will not cause damage to the folding member 12. In other embodiments, the first clamping portion 13 can also be made of materials such as silicone, as long as it will not damage the folding member 12, and no other restrictions are made in this embodiment.

[0041] like Figure 1-Figure 4 As shown, in order to prevent the folding member 12 from folding too much and causing the cart to be unable to be used normally, a limiter 14 is provided on the bottom bracket 17 so that the folding member 12 can rotate between the first clamping portion 13 and the limiter 14. By providing the limiter 14, it can be ensured that the maximum angle of the folding member 12 when opening in the direction away from the folding assembly 11 is when the folding member 12 abuts against the limiter 14; in this embodiment, the maximum folding angle of the folding member 12 is 90°, at which time the folding member 12 is in a horizontal state, and when placing items at this time, due to the existence of the limiter 14, the folding member 12 will not continue to rotate, and the load-bearing effect is good.

[0042] In order to adjust the folding angle of the folding member 12 at will, Figure 1 and Figure 2 As shown, one of the support rod 18 and the folding member 12 is provided with a fixing portion 15, and the other is provided with a hooking portion 16, so that the folding member 12 can be hooked at any position between the first clamping portion 13 and the limiting member 14. By providing the fixing portion 15 and the hooking portion 16, the angle at which the folding member 12 needs to be folded can be adjusted at will according to the actual size of the article, which is simple and convenient, and there is no need to fold the folding member 12 to a horizontal state every time, thereby improving the practicality of the cart.

[0043] It is worth noting that, in this embodiment, Figure 1 , Figure 2 and Figure 5As shown, a fixing portion 15 is provided on the support rod 18, and a hooking portion 16 is provided on the folding member 12. The fixing portion 15 is a cross bar bent toward the folding assembly 11, and the hooking portion 16 is an iron chain with multiple links. When in use, the folding member 12 can be fixed by hooking the links of the iron chain on the cross bar, and the folding angle of the folding member 12 can be adjusted by hooking different links on the cross bar. It is simple, practical, and easy to operate. In other embodiments, the hooking portion 16 can also be provided on the support rod 18, and the fixing portion 15 can be provided on the folding member 12; multiple fixing portions 15 are also provided at intervals along the vertical direction on the support rod 18, and the hooking portion 16 adjusts the required folding angle by hooking the fixing portions 15 of different heights. As long as the structure can realize the arbitrary adjustment of the folding angle of the folding member 12, it is within the public protection scope of this embodiment.

[0044] like Figure 1 and Figure 2 As shown, in order to ensure that the cart can be used with less effort, the cart also includes a push-pull member 30, one end of which is provided with a handle 31, and the other end is connected to the bottom bracket 17 through a universal member, so that the cart can be pushed and pulled in any direction. By providing the handle 31 at one end of the push-pull member 30, not only can the cart be pushed with less effort and more convenient, but also a rope can be wound around the handle 31 when necessary in actual situations, and the handle 31 can be pulled by the rope to pull the cart; in addition, the other end of the push-pull member 30 is connected to the bottom bracket 17 through a universal member, so that the cart can be pulled in any direction, which is more convenient in actual application.

[0045] Considering that the push-pull member 30 will take up space when not in use, Figure 1 and Figure 2 As shown, the push-pull member 30 is arranged at one end of the bottom bracket 17 along the length direction, and the side of the folding member 12 away from the folding assembly 11 is provided with a second clamping portion 121, and the second clamping portion 121 can be correspondingly clamped with the push-pull member 30. After the pushing and pulling is completed, the push-pull member 30 is clamped to the second clamping portion 121, which can reduce the space occupied by the cart.

[0046] To save effort when pushing and pulling the cart, Figure 1-Figure 3 As shown, the bottom end of the bottom bracket 17 is pivotally connected to a driving wheel 20, and the driving wheel 20 can drive the vehicle body 10 to move. For the convenience of connection, the driving wheel 20 is pivotally connected to the driving bracket 22, and the driving bracket 22 is arranged at the bottom of the bottom bracket 17. This structure is not only convenient for installation, but also convenient for subsequent maintenance and replacement of parts. In addition, in order to ensure the stable rigidity of the movement of the cart, two groups of driving wheels 20 are arranged along the length direction of the bottom bracket 17, and each group of driving wheels 20 is arranged along the width direction of the bottom bracket 17. When the bottom bracket 17 is folded, in order to prevent the two groups of driving wheels 20 from interfering with each other, as shown in FIG. Figure 3As shown, the distance between the two driving wheels 20 close to the push-pull member 30 is greater than the distance between the two driving wheels 20 away from the push-pull member 30. Through this arrangement, it can be ensured that when the vehicle body 10 is folded, the two driving wheels 20 away from the push-pull member 30 can be placed between the two driving wheels 20 close to the push-pull member 30, thereby minimizing space occupancy.

[0047] In order to better control the speed of the cart, a brake 21 is provided on the driving wheel 20. By providing the brake 21, the cart can be decelerated when the speed of the cart is too fast, thereby improving the safety of use. Figure 1-Figure 3 As shown, in this embodiment, the brake member 21 is only provided on the driving wheel 20 near the push-pull member 30, so that the user can easily step on the brake member 21 with his foot to stop the driving wheel 20 from moving forward during the process of pushing the cart.

[0048] Finally, when using the cart in this embodiment, if the item is small in size, directly open the folding component 11 and the bottom bracket 17 and place the item on the vehicle body 10; if the item is large in size, first open the folding component 11 and the bottom bracket 17, then fold the folding parts 12 at both ends of the vehicle body 10 to the required angle, and then place the item on the vehicle body 10, so that large items can be transported, which is simple and efficient.

[0049] In summary, the cart provided in this embodiment can ensure that the body 10 can be folded and can also transport large items, which is convenient and practical.

[0050] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention.
