In industrial applications, these transport vehicles do not require a driver and are powered by rechargeable batteries.

[0003] Currently, the outer shell of unmanned transport vehicles is usually fixed to the chassis with screws. However, for larger unmanned transport vehicles, due to their larger shell size, more screw holes need to be set on the shell and the base during installation. It is difficult to align the screw holes during assembly, and the correction of the position takes a long time. In addition, the process of removing and installing multiple screws is cumbersome and inefficient.

[0004] Therefore, there is an urgent need for an unmanned transport vehicle to solve the above problems. Summary of the Invention

[0039] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0040] Example 1

[0041] like Figures 1-5As shown, this embodiment provides an unmanned transport vehicle, which includes a base 100, a housing 200, and a connecting assembly. The housing 200 is fastened to the base 100, and the housing 200 and the base 100 together form a space for storing internal parts. The housing 200 and the base 100 are detachably connected by the connecting assembly. Specifically, the connecting assembly includes a lock head 300 and a latch 400. The lock head 300 is disposed on the inner side wall of the housing 200, and the latch 400 is disposed at the edge of the upper surface of the base 100. The lock head 300 and the latch 400 are connected... In this configuration, when the outer casing 200 is pressed down, the locking head 300 can engage with the latch 400, thereby fixing the outer casing 200 to the base 100. When it is necessary to disassemble the outer casing 200, only an upward force needs to be applied to the outer casing 200 to separate it from the base 100. Compared with the previous method of fixing with screws, the connecting components in this embodiment are easy to position and the installation steps are simple. No other tools are needed, the disassembly and assembly efficiency is high, and the repeated disassembly and assembly of screws can cause stripping. It also avoids the situation where the screws are overtightened and damage the outer casing 200.

[0042] Furthermore, in this embodiment, the outer shell 200 of the unmanned transport vehicle includes a top plate 201, and a front plate 210, a rear plate 220, a left end plate 230, and a right end plate 240 connected to the top plate 201. The base 100 includes a front edge 110, a rear edge 120, a left side edge 130, and a right side edge 140. The front plate 210 is connected to the front edge 110, the rear plate 220 is connected to the rear edge 120, the left end plate 230 is connected to the left side edge 130, and the right end plate 240 is connected to the right side edge 140. To ensure a secure connection between the outer casing 200 and the base 100, this embodiment provides several lock heads 300 and several latches 400. The lock heads 300 are respectively located on the inner sidewalls of the front plate 210, rear plate 220, left end plate 230, and right end plate 240, and the latches 400 are respectively located on the front edge 110, rear edge 120, left edge 130, and right edge 140. The lock heads 300 and latches 400 are arranged in a one-to-one correspondence, thereby firmly securing the outer casing 200 and the base 100.

[0043] For example, in this embodiment, the inner wall of the outer casing 200 is provided with a total of seven lock heads 300, of which two lock heads 300 are provided on the front plate 210, one lock head 300 is provided on the rear plate 220, two lock heads 300 are provided on the left side plate, and two lock heads 300 are provided on the right side plate. Correspondingly, the base 100 is provided with seven latches 400 at positions corresponding to the lock heads 300, of which two latches 400 are provided on the front edge 110, one latch 400 is provided on the rear edge 120, two latches 400 are provided on the left side edge 130, and two latches 400 are provided on the right side edge 140.

[0044] As an alternative solution, see further. Figure 2 In this embodiment, the latch 400 includes two symmetrically arranged spring pieces. Each spring piece includes a connecting portion 410, a snap-fit ​​portion 420, and a fixing portion 430 connected in sequence. The connecting portions 410 of the two spring pieces are interconnected, and the fixing portions 430 of the two spring pieces are disposed on the base 100. The snap-fit ​​portion 420 can elastically deform, thereby snapping the locking head 300 into place. In some embodiments, the connecting portions 410 of the two spring pieces can be connected by welding.

[0045] Furthermore, to ensure the mechanical strength of the buckle 400, a reinforcing plate 440 is provided on the fixing part 430 in this embodiment. The reinforcing plate 440 is triangularly arranged, and two adjacent sides of the reinforcing plate 440 are connected to the fixing part 430. The reinforcing plate 440 can provide effective support for the fixing part 430, ensuring the stability of the fixation. Optionally, in this embodiment, two reinforcing plates 440 are provided on the fixing part 430 of each spring piece, providing good support.

[0046] As an optional solution, in this embodiment, the fixing part 430 of the spring is provided with a first through hole 431, and the base 100 is provided with a first fixing hole 160. The first connector (not shown in the figure) passes through the first through hole 431 and is detachably fixed in the first fixing hole 160. The first connector can be a screw or bolt, etc., and of course other connectors can be used. This embodiment does not limit this.

[0047] Further, see Figure 5 , Figure 6 and Figure 7 The lock head 300 has two opposite sides recessed inward to form limiting grooves 310. The engaging portions 420 of the two spring pieces are arranged facing each other and can elastically deform. When the lock head 300 is pressed down, the two engaging portions 420 are respectively engaged in the corresponding limiting grooves 310. After the engaging portions 420 are engaged with the limiting grooves 310, the movement of the outer shell 200 along the height direction of the base 100 is restricted, and the fixing effect is good. At this time, the end face of the buckle 400 on the base 100 facing the outer shell 200 abuts against the inner side wall of the outer shell 200, thereby providing a certain support for the outer shell 200 and preventing the outer shell 200 from being recessed inward. More preferably, the end face of the limiting groove 310 is a rounded transition surface, which makes the engagement process smoother and the disassembly easier.

[0048] See also Figure 4 and Figure 5In this embodiment, the lock head 300 is provided with a second through hole 320, and the side wall of the outer shell 200 is provided with a second fixing hole 250. The second connector (not shown in the figure) passes through the second through hole 320 and is fixed in the second fixing hole 250. The lock head 300 can be detachably fixed to the inner side wall of the outer shell 200 through the second connector. Compared with the method of integral injection molding of the outer shell 200 and the lock head 300, the outer shell 200 and the lock head 300 in this embodiment adopt a separate setting, which is less likely to cause processing defects. Moreover, the wall thickness of the outer shell 200 is more uniform, avoiding the situation of excessive local wall thickness. The mold cost is lower. If the lock head 300 and the outer shell 200 are injection molded, a core pulling mechanism needs to be set on the injection mold during processing, which greatly increases the mold cost and makes it less economical.

[0049] See Figure 4 , Figure 8 and Figure 9 The base 100 is provided with a limiting hole 150, and the inner side wall of the outer shell 200 is provided with a limiting plate 260. The limiting plate 260 is provided with a limiting protrusion 261 at one end near the base 100. When the outer shell 200 is fastened to the base 100, the limiting protrusion 261 can be inserted into the limiting hole 150. Thus, the limiting protrusion 261 and the limiting hole 150 can cooperate with the buckle 400 to further position the outer shell 200, prevent the outer shell 200 from protruding outward, ensure the outer shell 200 has a good shape, and is not easy to bend or deform.

[0050] Example 2

[0051] This embodiment also provides an unmanned transport vehicle, which includes a base 100, a shell 200 and a connecting component. The difference between the unmanned transport vehicle in this embodiment and the unmanned transport vehicle in Embodiment 1 is that the structure of the connecting component of the unmanned transport vehicle is slightly different.

[0052] Specifically, in this embodiment, the snap fastener 400 of the connecting component includes a spring piece, which includes two snap-fit ​​parts 420 and two fixing parts 430. Both fixing parts 430 are fixed on the base 100. The spring piece can be formed by bending. Compared with the method of welding the two spring pieces together through the connecting part 410 in Embodiment 1, the snap fastener 400 in this embodiment has better mechanical strength and is less prone to breakage or poor welding.

[0053] The remaining structures in this embodiment are the same as those in Embodiment 1, and will not be described again here.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
