DETAILED DESCRIPTION

[0022] refer to Figure 1 and Figure 2 A dual-function omnidirectional vehicle includes a frame body 1, a housing 2, a support plate 3, a first wheel assembly, and a battery box 5. The housing 2 is disposed around the frame body 1, and the support plate 3 is disposed on the top of the housing 2. In this embodiment, the housing 2 is welded to the frame. A bearing seat 18 is provided on the frame body 1, and the support plate 3 is placed on the bearing seat 18 for carrying cargo. Of course, in other embodiments, the frame body 1, housing 2, and support plate 3 can also be assembled according to existing methods.

[0023] refer to Figure 4-Figure 6 The frame body 1 is provided with a limit bracket 6, which is provided with two limit bars 601 in parallel. The battery box 5 is placed on the limit bracket 6 and is restrained between the two limit bars 601. An opening for accessing the battery box 5 is provided on one side of the housing 2. This arrangement eliminates the need to remove screws when replacing the battery box 5. The battery box 5 can be replaced by simply pulling it out, making replacement of the battery box 5 more convenient and improving operational efficiency. In actual applications, a handle can also be provided on the battery box 5 to facilitate pushing and pulling.

[0024] It is worth noting that in the above solution, if the road surface is bumpy, the battery box 5 is likely to slide out of the opening. Therefore, the present invention has made the following improvements.

[0025] The limiting bracket 6 is provided with a limiting structure for locking the position of the battery box 5. The limiting structure includes a limiting seat 7 and a tightening component 8. The limiting seat 7 is fixedly connected to the limiting bracket 6. The tightening component 8 is connected to the limiting seat 7 and is used to tighten the battery box 5. In this way, the position of the battery box 5 is well limited to avoid accidental sliding out.

[0026] As an option, the tightening component 8 of this embodiment includes a locking pin 801, a spring 802 and a steel ball 803. The limiting seat 7 is provided with a threaded hole and a mounting hole in sequence along the direction close to the battery box 5. The locking pin 801 is connected to the threaded hole, the spring 802 and the steel ball 803 are arranged in the mounting hole, and the limiting strip 601 is provided with an avoidance hole for avoiding the steel ball 803. The steel ball 803 is pressed against the battery box 5 under the action of the spring 802. A groove for accommodating some of the steel balls 803 can also be provided on the side of the battery box 5 (not shown in the figure). It is easy to understand that in some embodiments, one end of the spring 802 can be welded and fixed to the locking top, and the other end of the spring 802 can be welded and fixed to the steel ball 803; in other embodiments, the spring 802 and the steel ball 803 can be directly placed in the mounting hole, but it should be ensured that the steel ball 803 can only partially slide out of the avoidance hole on the limit strip 601 (that is, ensure that the steel ball 803 can be pressed against the battery box 5), and cannot escape from the avoidance hole (that is, prevent the steel ball 803 from being completely ejected).

[0027] In other embodiments, the pressing member 8 can of course also be of other structures, for example, the pressing member 8 directly uses a spring 802 plunger. In addition, in actual applications, the above-mentioned limiting structures can be provided on both sides of the battery box 5, and the number of limiting structures is not limited, and can be one or more.

[0028] It is worth noting that if the battery box 5 overheats or catches fire due to an accidental collision during use, the safety of the goods being transported by the omnidirectional vehicle will be affected if the battery box 5 is not removed in time. Existing omnidirectional vehicles can only be removed manually by disassembling the battery box 5, which poses certain installation risks. Therefore, the present invention has made the following improvements.

[0029] The vehicle frame 1 is provided with an ejection mechanism for ejecting the battery box 5 out of the opening. The ejection mechanism includes a first electric push rod 9 and a first mounting base 10. The first mounting base 10 is fixedly connected to the vehicle frame 1. The first electric push rod 9 is mounted on the first mounting base 10. When the push rod of the electric push rod is extended, the battery box 5 can be pushed out of the opening, thereby separating it from the omnidirectional vehicle. In this way, the battery box 5 can be automatically separated from the omnidirectional vehicle in the event of overheating or fire. It should be understood that those skilled in the art can implement automatic control of the first electric push rod 9. For example, a temperature sensor can be provided on the battery box 5 to check the temperature, and the first electric push rod 9 can be activated when the temperature rises to a set threshold.

[0030] In this embodiment, a rubber block 11 is provided at the end of the first electric push rod 9, and a load-bearing block 12 corresponding to the position of the rubber block 11 is provided on the battery box 5. This arrangement can reduce the impact force of the first electric push rod 9 on the battery box 5. In addition, it is easy to understand that in actual application, one or more ejection mechanisms can be provided.

[0031] refer to Figure 1In this embodiment, the first wheel assembly includes four Mecanum wheels 4. It should be understood that the Mecanum wheels 4 are connected to a motor to drive their rotation. Because Mecanum wheels 4 have high requirements for their application site and are suitable for relatively smooth roads, they are difficult to operate on rough and complex terrain. Therefore, the following improvements have been made to this end.

[0032] refer to Figure 1-Figure 3 In addition to the first wheel assembly, the omnidirectional vehicle in FIG. 1 also has a second wheel assembly. The second wheel assembly includes a beam frame 13, four vacuum casters 14, and a lifting mechanism. The beam frame 13 includes two cross beams 131 and two longitudinal beams 132, which are welded together to form a rectangular frame structure. The vacuum casters 14 are located at the outer ends of the longitudinal beams 132, and the lifting mechanism is located on the vehicle frame body 1 to drive the beam frame 13 to rise and fall. The provision of the second wheel assembly facilitates the use of Mecanum wheels 4 on smooth roads and vacuum casters 14 on rough (or complex terrain) roads, thereby adapting to two different types of working conditions.

[0033] As an option, the lifting mechanism of this embodiment includes several second electric push rods 15, one end of the second electric push rod 15 is connected to the second mounting seat 16, the second mounting seat 16 is fixedly connected to the frame body 1, and the other end of the second electric push rod 15 is connected to the beam 13 through the connecting seat 17. In this way, the beam 13 can be raised and lowered by the extension and retraction of the second electric push rod 15, thereby realizing the switching between the first wheel group and the second wheel group.

[0034] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
