Description

Technical Field

[0001] The present invention relates to the technical field of outdoor tents, and particularly to an automatically telescopic tent frame. Background Art

[0002] As a common necessity for outdoor activities, a tent can provide a sheltered and windproof leisure place for people. With the continuous improvement of human requirements for the quality of life and the expansion of the scope of human activities, various functional tents that enhance the living experience have been continuously developed and launched.

[0003] At present, there are a wide variety of tent products on the market, and the structures adopted include assembled type, manually quick-opening type, semi-automatic vehicle-mounted type, inflatable type, and so on. Among them, the assembled tent requires multiple people to assemble and join manually, which is time-consuming and laborious; the tent that can be operated by a single person in the quick-opening type can only cover a small space, and the tent that can cover a slightly larger space requires multiple people to operate; the inflatable type takes a long time to open and is extremely inconvenient to fold up; the semi-automatic vehicle-mounted type has a large limitation in the usage scenario.

[0004] In summary, there is a contradiction in the tents on the market: that is, the automatic tent that can be operated by a single person has a too small space; the one with a large space cannot be operated by a single person and has poor portability. Summary of the Invention

[0005] The technical problem solved by the present invention is to provide an automatically telescopic tent frame that is convenient for a single person to operate and can cover a relatively large space at the same time.

[0006] To solve the above technical problem, the technical solution adopted by the present invention is: an automatically telescopic tent frame, including an installation body, a pull rod, a driving member, a folding arm assembly, and a plurality of support rods. One end of the support rod is rotatably connected to the installation body. A power source and a control module that are electrically connected are provided on the installation body. The driving member is provided on the installation body and is electrically connected to the control module;

[0007] The number of the pull rods and the number of the folding arm assemblies are both multiple and are arranged in one-to-one correspondence. The number of the folding arm assemblies is greater than or equal to three;

[0008] One end of the folding arm assembly is rotatably connected to the installation body. One end of the pull rod is rotatably connected to the folding arm assembly. The other end of the pull rod is rotatably connected to the driving member. The driving member is used to drive the folding arm assembly to expand and contract;

[0009] When the automatically telescopic tent frame is not fully extended, the other end of the support rod supports on the placement surface for placing the automatically telescopic tent frame; when the automatically telescopic tent frame is fully extended, the other end of the support rod is detachably connected to the folding arm assembly.

[0010] The beneficial effects of the present invention are as follows: After the user takes out the automatically retractable tent frame in the folded state, rotate the support rod, so as to use the support rod to support the installation body and raise the installation body, then control the automatically retractable tent frame to automatically extend through the control module, and finally rotate the support rod to connect the support rod with the extended folding arm assembly. A single person can realize the extension / retraction of the automatically retractable tent frame, with simple operation, fast erection, and the automatically retractable tent frame in the storage state occupies a small space and is convenient to carry; during the extension process of the automatically retractable tent frame, the support rod can support the installation body to provide enough extension space for the folding arm assembly. After the retractable tent frame is fully extended, the support rod can strengthen the structural strength of the automatically retractable tent frame, realizing multiple functions with one object. Moreover, when the support rod is connected to the folding arm assembly, the space in the middle of the automatically retractable tent frame can also be vacated for the user to use, which is beneficial to enhancing the user experience.

[0033] Embodiment 1

[0034] Please refer to Figures 1 to 6 , Embodiment 1 of the present invention is: Please combine Figure 1 , Figure 2 and Figure 4 , an automatically retractable tent frame, including an installation body 1, a pull rod 2, a driving member 4, a folding arm assembly 3, and a plurality of support rods 9. One end of the support rod 9 is rotatably connected to the installation body 1. A power source 7 and a control module 8 are electrically connected on the installation body 1. The driving member 4 is arranged on the installation body 1 and is electrically connected to the control module 8; preferably, the power source 7 is a storage battery.

[0035] Optionally, the storage battery can also supply power to external electrical devices at the same time. The external electrical devices include but are not limited to lighting fixtures, etc. When using the external electrical devices, the external electrical devices are connected to the installation body 1 and / or the folding arm assembly 3. Preferably, the external electrical devices are detachably connected to the installation body 1 and / or the folding arm assembly 3.

[0036] The number of the pull rods 2 and the number of the folding arm assemblies 3 are respectively multiple and are arranged in one-to-one correspondence. The number of the folding arm assemblies 3 is greater than or equal to three. In this embodiment, the number of the folding arm assemblies 3 is four. In other embodiments, the number of the folding arm assemblies 3 can also be five, six or more, so as to form a framework in the form of a yurt;

[0037] One end of the folding arm assembly 3 is rotatably connected to the mounting body 1, one end of the pull rod 2 is rotatably connected to the folding arm assembly 3, the other end of the pull rod 2 is rotatably connected to the driving member 4, and the driving member 4 is used to drive the folding arm assembly 3 to expand and contract;

[0038] Please refer to Figure 1 and Figure 3 , when the automatic telescopic tent frame is not fully extended, the other end of the support rod 9 supports on the placement surface for placing the automatic telescopic tent frame; when the automatic telescopic tent frame is fully extended, the other end of the support rod 9 is detachably connected to the folding arm assembly 3. The placement surface for placing the automatic telescopic tent frame includes but is not limited to the ground;

[0039] Preferably, the number of the support rods 9 is the same as the number of the folding arm assemblies 3, and the support rods 9 and the folding arm assemblies 3 are arranged in one-to-one correspondence. In this way, when the automatic telescopic tent frame is in the fully extended state, each folding arm assembly 3 can be strengthened by the corresponding support rod 9.

[0040] As Figure 1 shown, specifically, when the automatic telescopic tent frame is fully extended, the folding arm assembly 3 forms a vertical first part 391 and an overhead second part 392. One end of the first part 391 away from the second part 392 supports on the placement surface for placing the automatic telescopic tent frame, and one end of the second part 392 away from the first part 391 is connected to the mounting body 1; the connection position of the support rod 9 and the folding arm assembly 3 is located on the first part 391.

[0041] The connection method between the support rod 9 and the folding arm assembly 3 includes but is not limited to screw connection, snap connection, pin connection, etc.

[0042] It should be noted that there is no inevitable length relationship between the overall length of the first part 391 of the folding arm assembly 3 and the length of the support rod 9. For example, it is possible that the overall length of the first part 391 of the folding arm assembly 3 is longer than or shorter than the length of the support rod 9, but preferably the length of the support rod 9 is equal to the overall length of the first part 391 of the folding arm assembly 3.

[0043] To reduce the overall length of the automatic telescopic tent frame in the storage state, preferably the support rod 9 is a telescopic rod. Moreover, when the support rod 9 is a telescopic rod, it can make it more convenient for the user to switch the support state of the support rod 9, so that the support rod 9 changes from the state of supporting the ground to the state of supporting the folding arm assembly 3.

[0044] Please refer to Figure 1 , Figure 2 andFigures 4 to 6 Specifically, the folding arm assembly 3 includes a plurality of arm structures 31. Two adjacent arm structures 31 are rotatably connected. One end of the arm structure 31 is provided with a driving gear 32, and the other end of the arm structure 31 is provided with a driven gear 33 fixedly connected to the adjacent arm structure 31. The driving gear 32 and the driven gear 33 are both rotatable relative to the arm structure 31. The driving gear 32 and the driven gear 33 are connected by a chain drive. The other end of the arm structure 31 is further provided with a driving wheel 34 fixedly connected to the arm structure 31. The driving wheel 34 is non-rotatable relative to the arm structure 31, and the driving wheel 34 serves as the driving gear 32 of the adjacent arm structure 31.

The pull rod 2 is rotatably connected to the arm structure 31 at the head end of the folding arm assembly 3.

[0045] In the folding arm assembly 3, by changing the gear ratio between the driven gear 33 and the driving wheel 34, each arm structure 31 can be extended to a predetermined different angle, so that the extended folding skeleton can be formed into different shapes. The number of the arm structures 31 can be selected as required.

[0046] Since the arm structure 31 at the end of the folding arm assembly 3 does not need to drive the next arm structure 31, there is no need to provide accessories such as the chain, the driven gear 33 and the driving wheel 34 on the arm structure 31 at the end of the folding arm assembly 3, and there is no need to provide the driving wheel 34 on another arm structure 31 adjacent to the arm structure 31.

[0047] In this embodiment, the folding arm assembly 3 includes four arm structures 31. The two arm structures 31 close to the mounting body 1 constitute the second part 392 of the folding arm assembly 3, and the two arm structures 31 far from the mounting body 1 constitute the first part 391 of the folding arm assembly 3.
