For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0022] Embodiment 1: Refer to Figure 1 and Figure 4 , this embodiment provides an expandable trailer-mounted mobile workbench, including a first workbench 1 with a slide rail mechanism 6 inside; a second workbench 2 built in the first workbench 1 and horizontally slid out from the rear of the first workbench 1 through the slide rail mechanism 6; two third workbenches 3 are respectively hinged to the tops of the left and right sides of the first workbench 1, and after being unfolded, they together with the first workbench 1 and the slid-out second workbench 2 form a continuous operation tabletop. After the third workbench 3 is folded, it is stored on the side of the first workbench 1; a mobile wheel set 4 is arranged under the front and rear sides of the first workbench 1 for support and transportation; a trailer connection mechanism 5 is arranged on one side of the first workbench 1 for connecting a traction device.

[0023] It should be noted that a first support frame 7 is hinged to the bottom of the outer end of the second workbench 2. After the second workbench 2 slides out horizontally, the first support frame 7 can be rotated and unfolded to support on the ground. A second support frame 8 is hinged to the bottom of the outer end of the third workbench 3. When the third workbench 3 is unfolded to the horizontal position, the second support frame 8 can be rotated and unfolded to support on the ground.

[0024] It is worth noting that the towing connection mechanism 5 includes a multi-link towing structure, one end of which is connected to the first workbench 1, and the other end of which is provided with a towing buckle 51 adapted to a standard trailer interface.

[0025] In addition, after the third workbench 3 is unfolded, a detachable bottom storage plate 9 is provided underneath the third workbench 3 to increase storage space.

[0026] When this embodiment is deployed for use, first, the workbench is towed to the place of use by the towing device, and the moving wheels are used as support to park the workbench stably. Then, the second workbench is slid out horizontally through the slide rail mechanism, and then the first support frame is rotated 90° to vertically support it on the ground to ensure the stability of the second workbench. Next, the multi-link towing of the towing link mechanism is folded, and rotated along one of the hinge axes to be stored at the lower side of the first workbench. Finally, the third workbench is rotated from the side of the first workbench to a horizontal position, and the second support frame is rotated 90° to vertically support it on the ground. In this way, the third workbench, the first workbench and the second workbench that slides out together form a horizontally continuous workbench group. The storage process of this embodiment is opposite to the deployment process.

[0027] The structural design of this embodiment is reasonable and practical. By building the second workbench into the first workbench and sliding it out using a slide rail, and hinged the third workbench to the outer top edge of the first workbench and rotating it to unfold, a horizontally continuous workbench group is formed, which effectively expands the operating platform and display area, and can meet the needs of multi-person operation and product display. The folding storage structure, moving wheels and towing device of the second and third workbenches facilitate the storage and transportation of the workbenches. The second and third workbenches are respectively equipped with rotatable and unfoldable support frames to ensure the stability of the workbenches when in use. The bottom storage plate is detachable and can be stored in the first workbench, which further optimizes the storage space and reduces the volume during transportation and storage.

[0028] Example 2: Reference Figure 2 This embodiment is further improved on the basis of the embodiment 1. The third workbench 3 adopts a two-section folding structure. After unfolding, the adjacent worktops are connected by hinges to form a continuous plane, and the operating table and the product display surface are more spacious.

[0029] This embodiment provides more sufficient space for operations and sales activities, can better display goods and perform operations, and is particularly suitable for scenarios where more goods need to be displayed or where multiple people need to cooperate in complex operations. It further improves the practicality and functionality of the workbench and meets higher requirements for use.

[0030] Example 3: Reference Figure 3, this embodiment is a further improvement based on Embodiment 2. A modular interface 10 is provided on the top of the first workbench 1, and the additional function module 11 is detachably installed on the top of the first workbench 1. The modular interface 10 includes, but is not limited to, magnetic, snap or bolt type. After the additional function module 11 is removed, the first workbench 1 is restored to a horizontal operation tabletop. The additional function modules 11 provided on the top of the first workbench 1 include, but are not limited to, water tanks, sinks, faucets, beverage vending machines, etc.

[0031] It should be noted that a kitchenware module installation groove 12 is provided on the second workbench 2 for detachably clamping and installing the kitchenware module on the module installation groove 12.

[0032] It should be noted that a detachable side dish basket 13 and a seasoning basket 14 are provided on the third workbench 3. After removing them, the cover plate 15 is covered to form a horizontal operation tabletop.

[0033] After using this embodiment, first, remove the additional function modules, kitchenware modules, side dish baskets, seasoning baskets, etc. on the first workbench, the second workbench and the third workbench and store them separately. Then, cover the cover plate to make the third workbench surface flat, and remove the bottom storage board of the third workbench and place it inside the first workbench. Then, rotate and fold up the second support frame, and rotate and fold up the third workbench and store it on the side of the first workbench. Then, rotate and fold up the first support frame, and slide the second workbench into the first workbench through the slide rail mechanism. Finally, one end of the multi-link towing structure of the towing connection mechanism is connected to the first workbench. At this time, the overall workbench is compactly stored, with a reduced volume, facilitating transportation or storage through the mobile wheel group and the towing device. The usage process of this embodiment is opposite to the above process.

[0034] The various detachable function modules of this embodiment enrich the functions of the workbench, enabling it to meet more types of display or operation requirements, such as providing beverages, food preparation, etc. After use, the additional function modules can be conveniently removed and stored, reducing the overall volume of the workbench, facilitating transportation and storage, and taking into account both functional diversity and storage convenience.
