The right cargo box door, the rear cargo box door, and the left cargo box door are hinged to the cargo box base, and the left cargo box door and the right cargo box door are respectively connected to the front cargo box door and the rear cargo box door by a latch.
[0005] On the side of the front carriage door away from the carriage base, there are carriage handrails and cushions. The cushions are centrally located, and there are two sets of carriage handrails, symmetrically distributed at both ends of the front carriage door.
[0006] Handrails and mudguards are located on both sides of the base of the carriage, near the left and right carriage doors, respectively, and anti-collision pads are attached to the handrails.
[0007] The taillight panel is located below the base of the carriage, near the rear door.
[0008] As a further embodiment of this utility model: the handrail of the carriage is U-shaped, with the opening facing the front carriage door, and is fixed to the front carriage door.
[0009] As a further embodiment of this utility model: two sets of handrails are provided on each side of the carriage base, respectively near the front carriage door and the rear carriage door.
[0010] As a further embodiment of this utility model, the latch includes a buckle assembly and a lock hole.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] Using cargo box handrails can lengthen the overall lever arm of the cargo box, making the opening and closing of the cargo box easier and more convenient for people to use. At the same time, cargo box handrails can replace traditional seat armrests, achieving two uses in one, facilitating production and assembly, simplifying production processes, and reducing manufacturing costs.

[0022] The present invention will be further described below with reference to the accompanying drawings.
[0023] like Figure 1 and Figure 2 As shown, the cargo box of the tricycle, which is easy to open, includes a cargo box base 1 and a front cargo box door 11, a right cargo box door 2, a rear cargo box door 4 and a left cargo box door 9 connected to the four sides of the cargo box base 1. The right cargo box door 2, the rear cargo box door 4 and the left cargo box door 9 are hinged to the cargo box base 1, and the left cargo box door 9 and the right cargo box door 2 are connected to the front cargo box door 11 and the rear cargo box door 4 respectively by a latch 3.
[0024] Release the latches 3 connecting the rear cargo door 4 to the left cargo door 9 and the right cargo door 2, allowing the rear cargo door 4 to open outwards. Then release the latches 3 connecting the left cargo door 9 and the right cargo door 2 to the front cargo door 11, allowing the left cargo door 9 and the right cargo door 2 to open outwards. Figure 3 As shown;
[0025] On the side of the front cargo door 11 away from the cargo base 1, there is a cargo handrail 10 and a backrest 12. The backrest 12 is set in the center. There are two sets of cargo handrails 10, which are symmetrically distributed at both ends of the front cargo door 11. The cargo handrails 10 can replace traditional seat armrests in normal times. When it is necessary to open the cargo box as a whole, the cargo box can be opened upward through the cargo handrails 10.
[0026] Handrails 6 and mudguards 8 are respectively provided on both sides of the lower part of the carriage base 1 near the left carriage door 9 and the right carriage door 2. Anti-collision pads 7 are connected to the handrails 6. The design of the anti-collision pads 7 can prevent the left carriage door 9 and the right carriage door 2 from bumping when they are fully opened, and play a good protective role.
[0027] The taillight panel 5 is connected to the bottom of the carriage base 1 near the rear carriage door 4.
[0028] Furthermore, the handrail 10 of the carriage has a U-shaped structure, with its opening facing the front carriage door 11, and is fixed to the front carriage door 11. In its normal state, as follows... Figure 4 As shown, it can be used as a seat armrest; when lifted up, it resembles... Figure 5 As shown, the lever arm that can be extended by the cargo box makes it easy to open the cargo box via the cargo box handrail 10.
[0029] Furthermore, two sets of handrails 6 are provided on each side of the carriage base 1, respectively near the front carriage door 11 and the rear carriage door 4.
[0030] Furthermore, such as Figure 2 and Figure 3 As shown, the latch 3 includes a latch assembly 3.1 and a lock hole 3.2. The latch assembly 3.1 connecting the front cargo door 11 to the left cargo door 9 and the right cargo door 2 is located on the front cargo door 11 and includes a hook 3.1.1 and a hanging ring 3.1.2. The lock hole 3.2 is located on the side of the left cargo door 9 and the right cargo door 2. The latch assembly 3.1 connecting the rear cargo door 4 to the left cargo door 9 and the right cargo door 2 is also located on the rear cargo door 4, wherein the hook 3.1.1 is located on the left cargo door 9 and the right cargo door 2, and the hanging ring 3.1.2 and the lock hole 3.2 are located on the side of the rear cargo door 4.
[0031] In use, this utility model is in the following normal operating state: Figure 4As shown; when it needs to be opened, release the latches 3 connecting the rear cargo door 4 to the left cargo door 9 and the right cargo door 2, and the rear cargo door 4 can be opened outwards. Then release the latches 3 connecting the left cargo door 9 and the right cargo door 2 to the front cargo door 11, and the left cargo door 9 and the right cargo door 2 can be opened outwards, as shown. Figure 3 As shown; when it needs to be opened, it can be opened directly through the handrail 10 in normal use, as shown. Figure 5 As shown.
