Description

Technical Field

[0001] The utility model relates to the field of tents, in particular to a lifting structure of a roof tent. Background Art

[0002] Existing roof tents generally use a scissor mechanism to achieve lifting and retraction, so as to realize the deployment and storage of the tent, which is convenient for camping.

[0003] For example, the patent document with publication number CN219910256U discloses an electric lifting mechanism for a roof tent, including: a tent bottom cover and a tent top cover, the tops of the tent bottom cover and the tent top cover are fixedly installed with fixed brackets and guide rails, the fixed brackets and guide rails are both centrally symmetrically installed, a sliding block 1 is slidably installed on the inner side wall of the guide rail on one side, an opening and closing support rod 1 is rotatably installed on the top of the sliding block 1, and an opening and closing support rod 2 and an electric support rod are rotatably installed in the middle of the opening and closing support rod 1.

[0004] However, the above technology has two disadvantages. First, after being raised, there are two corners that are not supported and are easily deformed when subjected to external forces. Second, the two support rods of the scissor structure cannot be vertical, resulting in a limited height of the tent.

[0005] Therefore, a roof tent lifting structure is proposed to solve the above technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the purpose of the utility model is to provide a roof tent lifting structure, which has the advantages of strong stability and can maximize the height of the tent.

[0007] The technical solution adopted by the utility model to solve the problem is: a roof tent lifting structure, including: a base and a top cover, at least four lifting parts are arranged in the base, the lifting parts include a first support rod and a second support rod, one end of the first support rod and the second support rod are rotatably connected, the other ends of the first support rod and the second support rod are rotatably connected to the base and the top cover respectively, a hinge rod is rotatably installed on the first support rod, and the bottom end of the hinge rod can slide horizontally in the base.

[0008] As a further improvement of the above technical solution, there are four lifting parts, which are respectively located at the ends of both sides of the base.

[0009] As a further improvement of the above technical solution, the number of the lifting parts is greater than four, wherein four lifting parts are located at the ends of both sides of the base, and the remaining lifting parts are arranged on the other two sides of the base.

[0010] As a further improvement of the above technical solution, an arc-shaped limiting groove is provided on the first support rod, and a limiting shaft is fixedly installed on the second support rod, and the limiting shaft is slidably connected to the limiting groove.

[0011] As a further improvement of the above technical solution, it also includes a driving part, which is used to drive the bottom end of the hinge rod to slide.

[0012] As a further improvement of the above technical solution, the driving part is a pneumatic cylinder, an oil cylinder or a linear motor.

[0013] As a further improvement of the above technical solution, the driving part corresponds to the hinge rod one by one, the driving part is fixedly installed in the base, and the output end of the driving part is rotatably connected to the bottom end of the hinge rod.

[0014] As a further improvement of the above technical solution, one of the driving parts is connected to two hinged rods, the driving part is slidably installed in the base, and two ends of the driving part are rotatably connected to the two hinged rods located on the same side.

[0015] As a further improvement of the above technical solution, a bracket is fixedly installed in the base, a slider is slidably installed on the bracket, and the slider is fixedly connected to the driving part.

[0016] The beneficial effect of the utility model is that the lifting is realized by utilizing two mutually folded support rods. Compared with the scissor-type structure, on the one hand, the four corners of the tent can be supported to ensure stability, and on the other hand, the two support rods can be kept vertical to ensure the height of the tent to the greatest extent.

[0029] Reference Figures 1 to 6A roof tent lifting structure includes: a base 1 and a top cover 2, at least four lifting parts 3 are arranged in the base 1, and the lifting parts 3 include a first support rod 31 and a second support rod 32, one end of the first support rod 31 and the second support rod 32 are rotatably connected, and the other ends of the first support rod 31 and the second support rod 32 are rotatably connected to the base 1 and the top cover 2, respectively, and a hinge rod 4 is rotatably installed on the first support rod 31, and the bottom end of the hinge rod 4 can slide horizontally in the base 1. When in use, the bottom end of the hinge rod 4 slides toward the direction of the first support rod 31, driving the first support rod 31 to rotate outward, so that the connection between the first support rod 31 and the second support rod 32 can expand outward, and finally the first support rod 31 and the second support rod 32 can be in a vertical state, completing the lifting process; since each corner is provided with a lifting part 3, each corner of the tent can be supported, and the stability is strong, and since the first support rod 31 and the second support rod 32 can be kept vertical, the height of the tent can be guaranteed to the greatest extent.

[0030] As a preferred embodiment, there are four lifting parts 3 , and the four lifting parts 3 are respectively located at the ends of both sides of the base 1 .

[0031] As a preferred embodiment, the number of the lifting parts 3 is greater than four, wherein four lifting parts 3 are located at the ends of both sides of the base 1, and the remaining lifting parts are arranged at the other two sides of the base 1. The strength of the lifting structure can be ensured while being able to lift.

[0032] As a preferred embodiment, in order to prevent the first support rod 31 and the second support rod 32 from continuing to rotate after rotating to the highest point and causing the connection between the first support rod 31 and the second support rod 32 to expand outward and become unable to retract, an arc-shaped limit groove 311 is provided on the first support rod 31, and a limit shaft 321 is fixedly installed on the second support rod 32. The limit shaft 321 is slidably connected to the limit groove 311, which can effectively limit the rotation angle of the first support rod 31 and the second support rod 32 and ensure stable rotation.

[0033] As a preferred embodiment, it further comprises a driving part 5, and the driving part 5 is used to drive the bottom end of the hinge rod 4 to slide.

[0034] As a preferred embodiment, the driving unit 5 is a pneumatic cylinder, an oil cylinder or a linear motor, and the driving unit 5 corresponds one-to-one to the articulated rod 4 (not shown in the figure). The driving unit 5 is fixedly installed in the base 1, and the output shaft of the driving unit 5 is rotatably connected to the bottom end of the articulated rod 4.

[0035] As a preferred embodiment, the driving part 5 is a cylinder, an oil cylinder or a linear motor, one driving part 5 is connected to two articulated rods 4, the driving part 5 is slidably mounted in the base (1), and the two ends of the driving part 5 are rotatably connected to the two articulated rods 4 located on the same side. Since the force is mutual, when one end of the driving part 5 moves and generates resistance, it will exert force on the other end, so that the articulated rods 4 on both sides of the driving part 5 can be synchronized under the premise of reducing the use of electrical components, thereby reducing production costs.

[0036] As a preferred embodiment, a bracket 6 is fixedly installed in the base 1, a slider 7 is slidably installed on the bracket 6, and the slider 7 is fixedly connected to the driving part 5. The driving part 5 can slide and remain stable.
