Abstract
Description
Technical Field
[0001] The utility model relates to the field of carriage structures, in particular to a carriage structure of an electric tricycle. Background Art
[0002] Regarding the loading of cargo in electric tricycles, the traditional floor of the compartment is a flat structure, which means that loading cargo requires manual handling to the deep end of the compartment, which is time-consuming and labor-intensive. To address this shortcoming, patent application number 202222939435.5 proposes an improved solution for the compartment floor structure, aiming to improve loading and unloading efficiency by installing multiple roller sets. However, this solution still has the following two drawbacks:
[0003] 1. Cargo stability: While the roller design makes it easier for cargo to slide into the carriage, it also increases the amount of swaying during transportation. Especially when the carriage is not fully loaded, the risk of collision between cargo increases, potentially causing damage.
[0004] 2. Durability of the roller assembly: Since the weight of the cargo acts directly on the roller assembly, long-term high-load operation makes the roller assembly susceptible to wear, affecting its normal rotation function, thereby reducing the service life of the overall structure. Utility Model Content
[0005] The utility model provides a carriage structure of an electric tricycle, which can at least solve one problem pointed out in the background technology.
[0006] An electric tricycle compartment structure, comprising:
[0007] A plurality of roller assemblies are distributed along the length direction of the bottom plate of the carriage structure, and a receiving groove for receiving the plurality of roller assemblies is provided on the bottom plate;
[0008] A lifting unit, used to drive the multiple roller assemblies to rise and fall synchronously; and
[0009] A sealing assembly, used for closing the receiving groove;
[0010] Under the action of the lifting unit, the roller assembly can move from a position exposed outside the accommodating groove to a position inside the accommodating groove.
[0011] Preferably, the roller assembly includes a roller and two roller seats located at both ends of the roller;
[0012] A plurality of roller sleeves are arranged on the roller at intervals.
[0013] Preferably, the blocking assembly includes two sealing plates hinged to the notch of the accommodating slot.
[0014] Preferably, a fixing rod is inserted into the bottom plate, and the fixing rod passes through the bottom plate and the plurality of sealing plates.
[0015] Preferably, the lifting assembly includes a cylinder and a connecting frame connected to the output end of the cylinder, the cylinder is fixedly mounted on the lower side of the base plate, and the connecting frame is fixedly connected to the roller seats of all roller assemblies.
[0016] Preferably, a guide rod is fixedly installed in the accommodating groove, and a guide hole cooperating with the guide rod is opened on the roller seat.
[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention uses a lifting assembly to expose the roller assembly outside the receiving groove, so that the goods can be easily pushed from the rear of the vehicle to the deep part of the vehicle, saving time and effort. When the loading work is completed, the roller assembly is moved into the receiving groove through the lifting assembly, and the goods originally located on the roller assembly are in contact with the floor of the vehicle. The roller assembly is no longer subject to load, so the service life is greatly improved, and excessive shaking of the goods is avoided, which is safer. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] A specific embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.
[0026] like Figures 1 to 5As shown, an embodiment of the present invention provides an electric tricycle carriage structure, comprising a plurality of roller assemblies arranged on the carriage structure, a lifting unit for driving the plurality of roller assemblies to rise and fall synchronously, and a receiving groove 10 for accommodating the plurality of roller assemblies is provided on the bottom plate 1 of the carriage structure;
[0027] A plurality of roller assemblies are distributed along the length direction of the floor 1 of the carriage structure, that is, distributed in the direction from the front to the rear of the carriage. The roller assembly of this embodiment moves from a position exposed outside the receiving groove 10 to a position inside the receiving groove 10 under the action of the lifting unit. Therefore, when loading goods, the roller assembly is exposed outside the receiving groove 10 (that is, higher than the surface of the floor 1) through the lifting assembly, so that the goods can be easily pushed from the rear of the carriage to the deep part of the carriage, saving time and effort. When the loading work is completed, the roller assembly is moved into the receiving groove 10 through the lifting assembly, so that the goods originally located on the roller assembly are in contact with the carriage floor 1, and the roller assembly is no longer subjected to load, thereby greatly improving the service life and avoiding excessive shaking of the goods, which is safer.
[0028] In addition, in order to complete the transportation of bulk goods (such as agricultural and sideline products) on this basis, a sealing assembly for closing the receiving groove 10 is further provided on the bottom plate 1. Specifically, the sealing assembly includes two sealing plates 8 hingedly connected to the notches of the receiving groove 10. After the sealing plates 8 seal the receiving groove 10, bulk goods can be directly transported.
[0029] The roller assembly of this embodiment includes a roller 2 and two roller seats 3 located at both ends of the roller 2. A plurality of roller sleeves 4 are arranged on the roller 2 at intervals.
[0030] In addition, in order to achieve the fixation of the closing plate 8, a fixing rod 9 is further inserted into the bottom plate 1, and the fixing rod 9 passes through the bottom plate 1 and multiple closing plates 8, that is, the bottom plate 1 and multiple closing plates 8 are provided with a through groove that cooperates with the fixing rod 9. When the closing plate 8 is in a state of closing the receiving groove 10, the rear baffle is opened and the fixing rod 9 is inserted from one side of the bottom plate 1 to complete the fixation of all the fixing rods 9. This embodiment takes three fixing rods 9 as an example, and the ends of the fixing rods 9 can be fixedly connected with foldable handles;
[0031] In addition, any fixing rod 9 is located between the two roller sleeves 4, that is, the fixing rod 9 will not hinder the lifting and lowering of the roller assembly;
[0032] The lifting assembly of this embodiment includes a cylinder 7 and a connecting frame 6 connected to the output end of the cylinder 7. The cylinder 7 is fixedly installed on the lower side of the base plate 1. The connecting frame 6 is fixedly connected to the roller seats 3 of all roller assemblies. In addition, a guide rod 5 is fixedly installed in the accommodating groove 10, and a guide hole that cooperates with the guide rod 5 is opened on the roller seat 3.
[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit and essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
[0034] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
