DETAILED DESCRIPTION

[0043] The technical solutions in the embodiments of the utility model will be clearly and completely described in connection with the drawings in the embodiments of the utility model. It should be understood that the specific embodiments described herein are only used to explain the utility model and not used to limit the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0044] As shown in Figure 1 and Figure 4 , the embodiment provides a side frame expandable tipper, which comprises:

[0045] frame 1;

[0046] wheel 10 assembly, which is arranged on the lower side of the frame 1;And,

[0047] carriage, the carriage comprises a car plate 2 arranged on the frame 1 and four side frames arranged around the car plate 2, each side frame is hinged with the car plate 2, specifically can be hinged through hinge 9;Each adjacent two side frames are provided with a group of first locking assemblies 7, the first locking assembly 7 includes locking state for locking adjacent two side frames together and unlocking state for unlocking two side frames;

[0048] The carriage comprises a carriage state and an expansion state;When the carriage is in the carriage state, four side frames and the car plate 2 form a material containing groove, and each group of first locking assemblies 7 are in the locking state for locking adjacent two side frames together;When the carriage is in the expansion state, at least one side frame is rotated and expanded towards the outside of the car plate 2, and the first locking assembly 7 corresponding to the expanded side frame is in the unlocking state.

[0049] Specifically, as shown in Figure 1 and Figure 4As shown, the four side frames are the front side frame 3, the rear side frame 4, the left side frame 5, and the right side frame 6. When the dump truck is in the deployed state, the side frames rotate outward from the vehicle deck 2 to form a 180-degree angle with the vehicle deck 2. Specifically, because the front side frame 3 is provided with a pull rod 12 on the front side, when the dump truck is in the deployed state, the maximum load-bearing area is preferably achieved when the rear side frame 4, the left side frame 5, and the right side frame 6 are all deployed outward from the vehicle deck 2 to form a 180-degree angle with the vehicle deck 2. This facilitates the user to pull or push the dump truck via the pull rod 12. When the dump truck is in the loading state, the rear side frame 4 is preferably tilted backward and upward, making it easier for the user to tilt the dump truck to unload cargo.

[0050] Among them, such as Figure 2 As shown, the first locking assembly 7 can adopt a spring buckle in the prior art.

[0051] Among them, such as Figure 6 and Figure 7 As shown, the truck bed also includes a folded state. When the truck bed is in the folded state, each of the side frames rotates toward the vehicle deck 2 and folds above the vehicle deck 2, and all of the first locking assemblies 7 are in the unlocked state. In the folded state, a specific method is to fold the front side frame 3 and the rear side frame 4 first, and then fold the left side frame 5 and the right side frame 6, so that the left side frame 5 and the right side frame 6 are located above the front side frame 3 and the rear side frame 4.

[0052] In some embodiments, such as Figure 4 and Figure 5 As shown, the left and right sides of the vehicle plate 2 are each provided with a first abutment portion 22, and the lower ends of the left side frame 5 and the right side frame 6 are each provided with a second abutment portion 61. When the left side frame 5 is rotated and unfolded toward the left side of the vehicle plate 2, the second abutment portion 61 on the left side frame 5 abuts against the first abutment portion 22 on the left side of the vehicle plate 2, thereby causing the left side frame 5 to flip to a maximum angle of 180 degrees with the vehicle plate 2 and preventing the left side frame 5 from further flipping to the lower left. When the right side frame 6 is rotated and unfolded toward the right side of the vehicle plate 2, the second abutment portion 61 on the right side frame 6 abuts against the first abutment portion 22 on the right side of the vehicle plate 2, thereby causing the right side frame 6 to flip to a maximum angle of 180 degrees with the vehicle plate 2 and preventing the left side frame 5 from further flipping to the lower right. The first abutment portion 22 is specifically the left and right sides of the vehicle plate 2, and the second abutment portion 61 is specifically the lower end surface of the left side frame 5 and the lower end surface of the right side frame 6.

[0053] In some embodiments, such as Figure 4 and Figure 7As shown, in order to make the side frame more stable and better support when the car body carries objects in the unfolded state, a plurality of support frames 21 are arranged on the car plate 2, and a plurality of support frames 21 correspond to the rear side frame 4, the left side frame 5 and the right side frame 6, for example, when the number of the plurality of support frames 21 is six, two support frames 21 correspond to the rear side frame 4, two support frames 21 correspond to the left side frame 5, and two support frames 21 correspond to the right side frame 6; each of the support frames 21 includes a storage state below the car plate 2 and an extended state outside the car plate 2; when the support frame 21 is in the storage state, the support frame 21 is below the car plate 2; when the support frame 21 is in the extended state, the support frame 21 is supported on the lower side of the side frame corresponding to it and rotated and unfolded towards the outside of the car plate 2. Specifically, when the car body is in the unfolded state and needs to be turned outward to 180 degrees with the car plate 2, first move the support frame 21 corresponding to the side frame to the outside of the car plate 2 to make it in the extended state, and then rotate the side frame to abut on the upper side of the support frame 21, so that the support frame 21 plays a certain supporting role when loading objects, and the corresponding side frame is more stable.

[0054] As shown in the drawings, the support frame 21 can be rotatably connected with the car plate 2. Figure 7

[0055] Alternatively, the support frame 21 is slidably connected with the car plate 2. The specific scheme can be that the support frame 21 for supporting the left side frame 5 and the right side frame 6 is rotatably connected with the car plate 2, and the support frame 21 for supporting the rear side frame 4 is slidably connected with the car plate 2.

[0056] As shown in the drawings, Figure 1 and Figure 7 The car wheel 10 assembly has four groups, two of which are located below the front side of the car frame 1, and the other two are located below the rear side of the car frame 1.

[0057] Each of the car wheel 10 assemblies includes a car wheel frame 11 and a car wheel 10 rotatably arranged on the car wheel frame 11; and the car wheel frame 11 includes a folded state and an unfolded state relative to the car frame 1. Specifically, when the dump truck needs to be packaged, transported or stored, the four car wheel 10 assemblies and the four side frames can be switched to the folded state, so that the entire dump truck has a smaller volume.

[0058] As shown in the drawings, Figure 1 , Figure 3 and Figure 7 ​As shown, one side of each wheel frame 11 is hinged to the frame 1, specifically, by a hinge 9, and a set of second locking assemblies 8 are provided between the other side of each wheel frame 1 and the frame 1, and the second locking assemblies 8 include a locked state and an unlocked state; specifically, the right side of the wheel frame 11 located on the left side of the frame 1 is hinged to the frame 1, and the left side of the wheel frame 11 located on the right side of the frame 1 is hinged to the frame 1, so that after folding, all wheels 10 are folded to the bottom of the frame 1;

[0059] When the wheel frame 11 is in the unfolded state, the axis of the wheel 10 is parallel to the vehicle plate 2, and the second locking assembly 8 is in the locked state; when the wheel frame 11 is in the folded state, the axis of the wheel 10 is perpendicular to the vehicle plate 2, and the second locking assembly 8 is in the unlocked state. Specifically, when the wheel 10 assembly needs to be folded, the second locking assembly 8 needs to be switched to the unlocked state first; after the wheel 10 assembly is switched to the unfolded state, the user needs to switch the second locking assembly 8 to the locked state, so that the wheel 10 assembly is more stable in the unfolded state. The specific structure of the second locking assembly 8 can adopt the buckle structure in the prior art, and can also be configured so that the second locking assembly 8 includes a hook provided on the wheel frame 11 and a snap ring provided on the vehicle frame 1, and the hook specifically switches the second locking assembly 8 to the locked state or detaches from the snap ring through a micro-elastic clamp to switch the second locking assembly 8 to the unlocked state.

[0060] Among them, Figure 3 As shown, in order to facilitate the user to brake the dump truck, a foot brake 111 is provided on the wheel frame 11.

[0061] Among them, Figure 1 and Figure 4 As shown, in order to facilitate the user to operate the dump truck forward or backward, a pull rod 12 is provided on the front side of the frame 1, and a hand brake is provided on the pull rod 12;

[0062] The pull rod 12 is rotatably connected to the frame 1. Specifically, a pull rod connection seat 15 is provided on the front side of the frame 1. The lower end of the pull rod 12 is rotatably connected to the pull rod connection seat 15. Figure 7 As shown, when the dump truck is in a folded state, the pull rod 12 can be rotated to the bottom of the frame 1, thereby further reducing the volume of the entire dump truck and facilitating storage, packaging and transportation.

[0063] In some embodiments, such as Figure 1 and Figure 4 As shown, in order to facilitate the user to tip the dump truck, a handle 13 is provided on the front side of the frame 1 , and the user lifts the handle 13 upwards to tip the dump truck backward to dump the materials.

[0064] In some embodiments, as shown in Figure 1 In order to facilitate the use of the tipping cart to mount objects, a hook rack 14 is arranged on the left side frame 5 and the right side frame 6, and a hook 141 is arranged on the side away from the hopper of the hook rack 14, which is used to mount objects.

[0065] Working principle:

[0066] When the user switches the tipping cart to the hopper state, the four side frames and the car plate 2 form a container, and then the four groups of first locking assemblies 7 are switched to the locked state, which can be used to transport small objects or loose materials; when the user needs to transport large objects, the corresponding number of side frames can be unfolded to the outside of the car plate 2 to be 180 degrees with the car plate 2 according to the needs, at this time the hopper bearing area is increased, which can be used to transport large objects, and the stability during transportation is better.

[0067] The utility model is not limited to the above optional implementation, and the schemes can be combined arbitrarily on the premise of not being contradictory; anyone can derive other various forms of products under the inspiration of the utility model, but regardless of any changes in shape or structure, any technical scheme falling within the scope defined by the claims of the utility model falls within the protection scope of the utility model.
