Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1

[0024] Please refer to Figure 1 , a food vending truck shown in the figure, including a vehicle body 1, the vehicle body 1 includes a carriage 11, a lifting component 4 is arranged on one side inside the carriage 11, a display rack assembly 2 is installed in the lifting component 4, the display rack assembly 2 can be telescopic, and a support component 3 is arranged at the bottom of the display rack assembly 2;

[0025] A storage rack 112 is arranged inside the carriage 11, and a rotating door 111 is arranged on one side of the carriage 11.

[0026] In this solution, the storage rack 112 in the carriage 11 can be used by users to store items to be sold. The rotating door 111 is rotatably connected to the carriage 11. When selling goods, the rotating door 111 can be rotated and opened to facilitate the extension of the display rack assembly 2. At the same time, the rotating rotating door 111 can be used to block sunlight and prevent food from being overexposed to the sun.

[0027] Further, please refer to Figure 2 and Figure 4, the display rack assembly 2 includes a lifting platform 21. Inside both ends of the lifting platform 21, there is a first motor 212. The output end of the first motor 212 is connected to a worm 213. The worm 213 meshes with a worm gear 214. On one side of the worm gear 214, there is a rotating shaft 25;

[0028] The rotating shaft 25 is fixedly connected to the first connecting rod 24. The rotating shaft 25 passes through one end of the second connecting rod 23. The rotating shaft 25 is rotatably connected to the second connecting rod 23. The other end of the second connecting rod 23 is rotatably connected to a placement plate 22. In the middle of both ends of the placement plate 22, there is a third connecting rod 26 rotatably connected. One end of the third connecting rod 26 is rotatably connected to the lifting platform 21;

[0029] On the third connecting rod 26, there is a moving groove 261. One end of the first connecting rod 24 is arranged in the moving groove 261. The other end of the third connecting rod 26 is rotatably connected to another placement plate 22. Both ends of the other placement plate 22 are rotatably connected to a fourth connecting rod 27. One end of the fourth connecting rod 27 is rotatably connected to the placement plate 22.

[0030] Specifically, the display rack assembly 2 can automatically expand and contract, saving the user's time for setting up and taking down the stall and reducing the user's labor intensity. When unfolding, the first motor 212 is used to drive the worm 213 to rotate. Due to the meshing of the worm 213 and the worm gear 214, the worm 213 drives the worm gear 214 to rotate. When the worm gear 214 rotates, the rotating shaft 25 fixedly connected to the worm gear 214 can rotate, thereby driving the first connecting rod 24 at one end of the rotating shaft 25 to rotate. During the rotation of the first connecting rod 24, one end of the first connecting rod 24 moves in the moving groove 261, and at the same time, the included angle between the first connecting rod 24 and the third connecting rod 26 becomes larger, so that the third connecting rod 26 rotates around the lifting platform 21, enabling the third connecting rod 26 to rotate to be perpendicular to the lifting platform 21;

[0031] When the third connecting rod 26 rotates, it will drive the placement plate 22 to move. One end of the placement plate 22 is connected to the lifting platform 21 through the second connecting rod 23, so that a parallelogram structure is formed among the lifting platform 21, the second connecting rod 23, the third connecting rod 26, and the placement plate 22. Thus, the placement plate 22 always remains parallel to the lifting platform 21 and in a horizontal state when unfolding. The other placement plate 22 is connected through the fourth connecting rod 27 and the third connecting rod 26 to form a parallelogram structure, which facilitates the further unfolding of the other placement plate 22, enabling the display rack assembly 2 to be in a stepped shape after unfolding, providing a multi-level display space, and making it more convenient for the audience to view and select the displayed items;

[0032] The display stand assembly 2 uses a worm 213 and a worm gear 214 to control the telescoping. The transmission between the worm 213 and the worm gear 214 has good self-locking property. When the deployed placement plate 22 is affected by the outside world, the self-locking function of the worm 213 and the worm gear 214 can effectively prevent the first connecting rod 24 from rotating, thereby avoiding the deflection of the second connecting rod 23, the third connecting rod 26, and the fourth connecting rod 27, and further ensuring the stability of the placement plate 22. At the same time, the parallelogram structure formed by multiple connecting rods in the display stand assembly 2 can keep the placement plate 22 in a horizontal state all the time, thus avoiding the inclination of the placement plate 22.

[0033] Further, please refer to Figure 3 and Figure 5 The support assembly 3 is arranged below the bottom placement plate 22 in the display stand assembly 2. The support assembly 3 includes a connecting pipe 31. A spring 32 is arranged inside the connecting pipe 31. The spring 32 is connected to a support frame 33. The support frame 33 is slidably arranged in the connecting pipe 31.

[0034] The lifting assembly 4 includes a second motor 41. The second motor 41 is arranged inside the bottom of the carriage 11. The output end of the second motor 41 is connected to a threaded rod 42. The threaded rod 42 passes through the connecting plates 216 at both ends of the lifting platform 21. Two slide rods 43 are arranged in parallel on both sides of the threaded rod 42. The slide rods 43 are fixed to the bottom of the top plate 44. The threaded rod 42 is rotatably connected to the top plate 44. The top plate 44 is connected to the inner top of the carriage 11.

[0035] A display board 211 is arranged on one side of the lifting platform 21. A placement groove 221 is arranged on the placement plate 22.

[0036] Specifically, the support assembly 3 is used to support the display stand assembly 2. In the support assembly 3, the support frame 33 is connected to the connecting pipe 31 through the spring 32. When the lifting assembly 4 is used to control the lifting of the display stand assembly 2, the support assembly 3 at the bottom of the display stand assembly 2 can be close to the ground. During the contact process between the support frame 33 and the ground, the support frames 33 in different support assemblies 3 can squeeze the spring 32 according to different ground conditions, so that the display stand assembly 2 can be applicable to rough ground.

[0037] The lifting component 4 can control the lifting of the display rack component 2. During the lifting process, the second motor 41 is used to control the rotation of the threaded rod 42. The threaded rod 42 is helically connected to the connecting plates 216 at both ends of the lifting platform 21, so that the lifting platform 21 can rise and fall along the slide rod 43 during the rotation of the threaded rod 42, facilitating the unfolding of the display rack component 2. When it is necessary to sell, the first motor 212 inside the display rack component 2 drives the display rack component 2 to unfold. After the display rack component 2 unfolds, the second motor 41 is used to control the descent of the display rack component 2 until the support component 3 is close to the ground, and then the second motor 41 controls the display rack component 2 to stop moving. When it is necessary to pack up the stall, the lifting component 4 controls the display rack component 2 to be lifted. When the lifting platform 21 is in contact with the top plate 44, the first motor 212 in the lifting platform 21 controls the display rack component 2 to contract, making the display rack component 2 contract as shown in Figure 5 shown, thus enabling the user to quickly set up and pack up the stall and avoiding excessive labor;

[0038] The display board 211 on the lifting platform 21 is used to place the promotional board for the user to sell items. The placement slots 221 on the placement board 22 can hold items and prevent the items from falling off the placement board 22.
