[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Please see Figure 1 - Figure 5 This embodiment of a service cart with folding and lifting functions includes a cart 1, which is equipped with a lifting mechanism to facilitate the adjustment of the height of the service cart platform 211, making it convenient for people of different heights to use. The lifting mechanism is equipped with a folding mechanism to increase the placement range of the platform 211, making it convenient for placing items. The lifting mechanism includes a lifting component 2, which includes a limiting cylinder 21. The limiting cylinder 21 is fixedly installed on the cart 1. A limiting post 25 is slidably provided on the inner wall of the limiting cylinder 21. The platform 211 is fixed at the top of the limiting post 25. A receiving block 27 is provided at the bottom of the platform 211. A sliding rod 210 is installed on the cart 1. A moving block 24 is slidably provided on the sliding rod 210. Both ends of the moving block 24 are rotatably connected to a support rod 26. One end of the support rod 26 is rotatably connected to one end of the receiving block 27. The support rod 26, in conjunction with the receiving block 27, is used to move the platform 211.

[0027] The folding mechanism includes a folding assembly 3, which includes a hinge 31. The hinge 31 is fixedly installed on the base 211. A receiving plate 32 is fixedly installed on one side of the hinge 31. A support plate 33 is provided at the bottom of the base 211. A vertical plate 34 is fixedly installed at the bottom of the base 211. A horizontal bar 37 is slidably provided on the vertical plate 34. One end of the horizontal bar 37 is rotatably connected to a limiting buckle 38. The limiting buckle 38 is designed to lock the receiving plate 32 onto the base 211 when the receiving plate 32 is folded onto the base 211, thereby limiting and fixing the receiving plate 32.

[0028] The trolley 1 is equipped with a handrail 4 and at least four limiting cylinders 21. The limiting cylinders 21 are vertically arranged and are cylindrical in shape. The limiting posts 25 are cylindrical rods and are vertically arranged. The cross-sectional dimensions of the limiting posts 25 are adapted to the cross-sectional dimensions of the inner wall of the limiting cylinders 21. The setting of the limiting posts 25 and the limiting cylinders 21 serves to limit the movement of the support platform 211, which facilitates the vertical movement of the support platform 211.

[0029] There are at least two slide bars 210, and the slide bars 210 are L-shaped. The moving block 24 and the receiving block 27 are both horizontally set. The moving block 24 and the receiving block 27 are both square rods. The moving block 24 is set to drive the support rod 26 to move.

[0030] The trolley 1 is equipped with a bracket 28, which is L-shaped. A motor 29 is fixedly installed on the inner wall of the bracket 28. The motor 29 has forward and reverse rotation functions. The motor 29 is used to drive the gear 23 to rotate. The gear 23 is fixed to the end of the shaft of the motor 29. A rack 22 is fixedly installed at the bottom of the moving block 24. The rack 22 meshes with the gear 23. By setting the gear 23 and the rack 22, when the motor 29 is working, it drives the moving blocks 24 on both sides to slide in opposite directions along the surface of the slide rod 210.

[0031] There are at least two hinges 31, and the support plate 32 is square in shape. The support plate 32 is provided to increase the placement range of the support platform 211.

[0032] The support plate 33 is a strip plate and is set horizontally. The crossbar 37 is a square bar and the limiting buckle 38 is C-shaped. The limiting buckle 38 is set to lock the receiving plate 32 and the support platform 211.

[0033] A limit block 36 is fixedly installed at the other end of the crossbar 37. A spring 35 is provided on the side of the limit block 36. The spring 35 is wound around the crossbar 37. One end of the spring 35 is fixedly connected to the side of the vertical plate 34. The spring 35 is used to apply force to the limit buckle 38.

[0034] When the height of the support platform 211 needs to be adjusted, the motor 29 is started. The motor 29 drives the gear 23 to rotate. The gear 23 meshes with the rack 22, which will drive the racks 22 on both sides to move. When the racks 22 on both sides move, they will drive the moving blocks 24 on both sides to move in the opposite direction along the surface of the slide bar 210. When the moving blocks 24 on both sides move in the opposite direction, they will drive the support platform 211 to move through the support rod 26 and the receiving block 27. When the support platform 211 moves, it is limited by the limiting cylinder 21 and the limiting post 25. The support platform 211 will move vertically upward until the support platform 211 moves to a suitable height position, which is convenient for people of different heights to use.

[0035] By incorporating a foldable support plate 32, the carrying capacity of the service vehicle can be increased. When the support plate 32 needs to be folded and secured, it is folded onto the platform 211 using the hinge 31. Then, the limiting buckle 38 is pulled out to the appropriate position. The limiting buckle 38 is then rotated so that its locking interface faces the folded position of the platform 211 and the support plate 32. The limiting buckle 38 is then slowly released, and under the action of the spring 35, it locks onto the support plate 32 and the platform 211. This design facilitates the securing of the folded support plate 32, making it easier to move the trolley 1 later.

[0036] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
