[0004] The above technical solution drives two electric cylinders simultaneously to make the tent unfold in an inclined manner, but such unfolding method will result in limited space inside the tent, which is not suitable for family travel, and the space inside the tent cannot meet the space requirements for multiple people to live in. Utility Model Content

[0005] The utility model aims to solve the problem in the prior art that the inclined unfolding of the tent will result in limited internal space of the tent and cannot meet the space requirements of multiple people living in the tent, and proposes an automatically unfolding vehicle-mounted tent.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An automatically deployable vehicle-mounted tent comprises a base and an upper cover for use together, the base is connected with four first traction rods, the upper cover is connected with four second traction rods connected with the first traction rods, and the base is connected with four cylinders connected with the first traction rods and the connecting parts of the second traction rods;

[0008] A support assembly is arranged between the base and the upper cover for guiding and supporting the two.

[0009] Preferably, the base and the upper cover are covered with a cloth, the lower end of the first traction rod is pin-connected to the base, and the upper end of the second traction rod is pin-connected to the upper cover.

[0010] Preferably, one first traction rod, one second traction rod and one cylinder form a group, and the upper ends of the first traction rods and the lower ends of the second traction rods in the left and right groups are connected and installed with the output end of the cylinder through the same pin shaft.

[0011] Preferably, the support assembly comprises two first guide sliders slidably mounted on the base, two second guide sliders slidably mounted on the upper cover, and a telescopic bracket is arranged between the first guide slider and the second guide slider.

[0012] Preferably, the base is provided with a first guide slot for slidingly fitting the first guide slider, and the upper cover is provided with a second guide slot for slidingly fitting the second guide slider.

[0013] Preferably, the telescopic bracket is composed of a plurality of cross-arranged connecting rods, the connection points of two cross-connected connecting rods are connected by pins, and the ends of two connecting rods are connected by pins.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] In the utility model, four cylinders are used as driving sources, and the telescopic movement of the cylinder output ends is utilized to drive the first traction rod and the second traction rod to deflect. When the first traction rod and the second traction rod are deflected, a position difference is generated, thereby supporting the upper cover to be raised and lowered, thereby realizing automatic deployment of the tent. Compared with the prior art in which the tent is tilted and deployed by driving an electric cylinder, the present technical solution uses four cylinders to simultaneously support the four corners of the upper cover to move upward, thereby enabling the tent to be deployed vertically, helping to increase the internal space of the tent to meet the living needs of multiple people traveling.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 3 , an automatically deployable vehicle-mounted tent, comprising a base 1 and an upper cover 2 for use together, wherein a cloth is set around the base 1 and the upper cover 2. It should be noted that the connection method of the cloth, the base 1 and the upper cover 2 can refer to the reference document proposed in the background technology;

[0022] Four first traction rods 3 are connected to the base 1 by pins, four second traction rods 4 connected to the first traction rods 3 by pins are connected to the upper cover 2 by pins, four cylinders 5 connected to the first traction rods 3 and the second traction rods 4 by pins are connected to the base 1 by pins, one first traction rod 3, one second traction rod 4 and one cylinder 5 form a group, and the upper cover 2 can be supported to move vertically upward by four groups of first traction rods 3, second traction rods 4 and cylinders 5, so that the tent can be vertically unfolded, which helps to increase the use space inside the tent;

[0023] A support assembly is provided between the base 1 and the upper cover 2 for guiding and supporting the two. The support assembly guides and supports the vertical movement of the base 1 and the upper cover 2, which helps to improve the stability of the tent when it is deployed.

[0024] Further explanation: the support assembly includes two first guide sliders 6 slidably mounted on the base 1, and the base 1 is provided with a first guide slot for slidingly mounting the first guide sliders 6, and the motion trajectory of the first guide sliders 6 can be limited by the first guide slot;
