Mobile vehicles

Abstract

This disclosure provides a mobile carrier that primarily addresses the problem of alignment errors during the handling of precision equipment. The mobile carrier includes a base and a support device. The support device includes a base, a platform, and multiple fine-tuning modules. The fine-tuning modules are respectively disposed between the four corners of the base and the platform. Each fine-tuning module includes a drive element, a transmission element, and a micro-tilt joint element. The drive element receives manual operation; the transmission element is coupled to the drive element to convert manual operation into lifting displacement; the micro-tilt joint element is coupled between the transmission element and the platform to provide support force and allow the platform to tilt relative to the transmission element at an angle. Through the above, by independently driving the fine-tuning modules in conjunction with the micro-tilt joint elements, the local height and tilt angle of the platform can be precisely adjusted, achieving accurate alignment.

Claims

1. A mobile vehicle, comprising: a base; The system also includes a support device disposed on the base. The support device comprises a base, a platform, and a plurality of fine-tuning modules. The platform is disposed on the base and includes four end corners. The plurality of fine-tuning modules are respectively disposed between the base and the four end corners of the platform. Each fine-tuning module includes: a drive element for receiving manual operation; and a transmission element coupled to the drive element for converting the manual operation into lifting displacement. And a micro-biased joint element, coupled between the transmission element and the platform, to provide support force and allow the platform to tilt relative to the transmission element; wherein, by manually operating the drive element of each fine-tuning module independently, the corresponding transmission element is linked to generate the lifting displacement, and the local height and tilt angle of the four corners of the platform are independently adjusted by the corresponding micro-biased joint element.

2. The mobile vehicle as described in claim 1, wherein, Each fine-tuning module's transmission element includes a threaded unit, and each fine-tuning module's drive element is a rotating unit. When the rotating unit rotates, it drives the threaded unit to generate the aforementioned lifting displacement.

3. The mobile vehicle as described in claim 2, wherein, Each of the fine-tuning modules includes a micro-biased planar joint base, which includes a spherical contact portion that supports the platform and allows the spherical contact portion to generate a relative deflection angle with respect to the transmission element.

4. The mobile vehicle as described in claim 1, wherein, Each of the fine-tuning modules further includes an indicator element disposed adjacent to the drive element for displaying the height adjustment amount of the lifting displacement.

5. The mobile vehicle as described in claim 1, wherein, The platform further includes a drive wheel assembly for carrying and sliding a cargo. The mobile vehicle also includes a safety locking mechanism, which includes a sensing element and a control unit. The sensing element is disposed on the platform to detect the positioning state of the cargo. The control unit is coupled to the sensing element, the drive wheel assembly, and the base. The control unit is used to execute a mutual exclusion locking logic according to the positioning state to selectively lock either the drive wheel assembly or the base.

6. The mobile vehicle as described in claim 5, wherein, The mutual exclusion lock-up logic includes a first control state and a second control state. In the first control state, the control unit locks the transmission wheel assembly and unlocks the base's mobility. In the second control state, the control unit unlocks the transmission wheel assembly and locks the base's mobility.

7. The mobile vehicle as described in claim 6, wherein, The sensing element includes a physical switch and a photoelectric sensor, the photoelectric sensor being coupled to the physical switch to trigger the control unit to switch to the first control state or the second control state based on one of the open / closed states of the physical switch.

8. The mobile vehicle as described in claim 7, wherein, It also includes a second support device, which has the same structure as the support device. The second support device is located above the support device and maintains a fixed distance from it. The second support device and the support device are linked to each other to perform lifting and lowering operations synchronously.

9. The mobile vehicle as described in claim 8, wherein, It also includes a lifting track, and the supporting device and the second supporting device are coupled to the lifting track to slide synchronously along the lifting track in order to maintain a fixed distance between the supporting device and the second supporting device.

10. The mobile vehicle as described in claim 9, wherein, The platform includes an opening that is perpendicular to the lifting track, allowing the goods to slide into or out of the platform.
