Description

Technical Field

[0001] This utility model relates to the technical field of automatic tents, specifically an automatic deployment and retraction support structure and an automatic tent. Background Technology

[0002] When automatic tents or awnings are deployed or retracted, the legs also extend and retract along with them. The legs are generally composed of multiple hinged support pole units. During the deployment and retraction process, the adjacent support pole units will swing relative to each other. Therefore, the stability of the connection between adjacent support pole units after deployment is crucial.

[0003] Existing support structures require simultaneous deployment from multiple locations or coordinated operation by multiple people. Therefore, some support structures adopt automatic deployment structures that can be operated by one person. For example, a retractable structure is set at the top of the support structure to enable press-to-deploy. However, such support structures are generally achieved by connecting multiple links in sequence with auxiliary support rods. This results in poor support stability of a single rod after the support structure is deployed, and it is only suitable for relatively small support structures. In addition, ground stakes are required to fix the structure after deployment, resulting in relatively poor stability. Utility Model Content

[0004] The purpose of this invention is to provide an automatic deployment and retraction support structure and an automatic tent to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic unfolding support structure includes an unfolding frame and a tent cloth that covers the unfolding frame after it is unfolded. The unfolding frame includes:

[0007] Multiple sets of folding units arranged horizontally and capable of closing or unfolding together, with adjacent folding units connected by multiple second intersecting members, wherein:

[0008] The folding unit includes:

[0009] Multiple first intersecting rods connected in sequence form an arc-shaped support after the folding unit is unfolded;

[0010] It also includes a locking element, which is disposed at the connection position of two adjacent first cross rods. When the locking element is in the locked state, the included angle of the first cross rods is fixed.

[0011] The automatic retractable support structure as described above: the intersection of the first and second intersecting rods along the length direction is respectively hinged to the first and second connecting heads.

[0012] The automatic retractable support structure described above: both the first connecting head and the second connecting head have four hinge positions, which are located on two vertical planes.

[0013] As described above, the automatic retractable support structure has two first connecting ends at both ends of the first cross member. The two opposite first connecting ends of two adjacent first cross members are respectively hinged to two hinge positions on the same vertical plane of the first connecting head and the second connecting head.

[0014] As described above, in the automatic retractable support structure: both first connecting ends of the first cross member located at both ends of the arc-shaped support member are hinged with feet.

[0015] As described above, the automatic retractable support structure has two second connecting ends at both ends of the second cross member. The two opposite second connecting ends of two adjacent second cross members are respectively hinged to the two hinge positions of the first connecting head and the second connecting head on another vertical plane.

[0016] As described above, in the automatic retractable support structure: after the first cross member is deployed, the included angle between the two first connecting ends hinged to the first connecting head is smaller than the included angle between the two first connecting ends hinged to the second connecting head.

[0017] The automatic retractable support structure as described above: the locking member connects a first connecting head and a second connecting head that are disposed opposite to each other, wherein the locking member includes a locking rod connected to the first connecting head, the locking rod is provided with a locking buckle, and also includes a hook installed on the second connecting head, the locking buckle being fastened to the hook to lock the relative position of the first connecting head and the second connecting head.

[0018] As described above, the automatic retraction and unfolding support structure has the following features: after the folding unit is unfolded, guide wheels are rotatably installed at the opposite ends of the first and second connecting heads located at its upper end. The ropes arranged along the lateral unfolding direction of the multiple folding units pass around the first and second connecting heads on the multiple folding units in sequence, and the two ends of the ropes are connected to the winch mechanism installed on the first connecting head.

[0019] The automatic tent structure described above: an automatic tent, characterized in that it includes a tent fabric and the automatic tent structure, wherein after the automatic tent structure is deployed, the tent fabric covers the automatic tent structure.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] The second crossbar allows multiple folding units to unfold horizontally. Simultaneously, the unfolding of multiple first crossbars forms a near-arc-shaped support, enabling the unfolding and folding of the tent frame. The combination of the first and second crossbars creates a triangular shape after the frame is unfolded, effectively increasing its stability and enabling it to withstand the weight of the automatic tent and external forces, reducing the possibility of swaying and deformation. Furthermore, the locking mechanism allows for locking at one or two points on each folding unit, restricting its unfolded state and simplifying operation.

[0022] The hinge openings of the first and second connecting rods are oriented opposite each other, so that when the first and second cross rods are folded, the first and second connecting rods move away from each other. During unfolding or retracting, only one set of the first and second connecting rods needs to be pushed to move relative to or opposite to each other to achieve the overall movement of the unfolding frame. The operation is convenient and does not require complicated steps to adjust the position of each component separately, effectively reducing the unfolding or retracting time of the unfolding frame. At the same time, the included angles of multiple first and second cross rods change synchronously when the unfolding frame is unfolded, so that the support force at each position of the unfolding frame is the same, which can effectively play a role in distributing external forces and further improve the stability of the unfolding frame.

[0033] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0034] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0035] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0036] In this embodiment of the utility model, please refer to Figure 2 and Figure 9 An automatic retractable support structure includes a retractable frame 2, which has an unfolded state (e.g., Figure 2 ) and the collapsed state (such as Figure 9 When the display rack 2 is in the retracted state, it can be placed directly on the base tray 3.

[0037] An automatic tent is also proposed, comprising a tent fabric 1 that covers the unfolding frame 2 after it is deployed, forming the automatic tent (e.g., Figure 1 ).

[0038] For details, please refer to Figures 2-5 The unfolding rack 2 includes multiple sets of folding units arranged horizontally and capable of being brought together or unfolded. Adjacent folding units are connected by multiple second cross rods 209, wherein:

[0039] The folding unit includes a plurality of first cross rods 201 connected in sequence. After the folding unit is unfolded, the plurality of first cross rods 201 form an arc-shaped support. It also includes a locking member, which is disposed at the connection position of two adjacent first cross rods 201. When the locking member is in the locked state, the included angle of the first cross rods 201 is fixed.

[0040] The second crossbar 209 allows multiple folding units to unfold horizontally. Simultaneously, the unfolding of multiple first crossbars 201 forms a near-arc-shaped support, enabling the unfolding and folding of the folding frame 2. The arrangement of the first crossbars 201 and second crossbars 209 creates a triangular shape after the folding frame 2 is unfolded, effectively increasing its stability and enabling it to withstand the weight of the automatic tent itself and external forces, reducing the possibility of swaying and deformation. Furthermore, the locking mechanism allows for locking at one or two points on each folding unit, restricting its unfolded state and facilitating operation.

[0041] Further, please refer to Figure 3 and Figure 6 The first cross member 201 and the second cross member 209 are hinged to the first connecting head 202 and the second connecting head 203 respectively at their intersection points along the length direction to realize the connection between the first cross member 201 and the second cross member 209. Specifically, the first cross member 201 includes a first connecting rod 2011 and a second connecting rod 2012 rotatably connected at the middle position, and the second cross member 209 includes a third connecting rod 2091 and a fourth connecting rod 2092 rotatably connected at the middle position.

[0042] Within the same folding unit, the first connecting rod 2011 and the second connecting rod 2012 of two adjacent first intersecting rods 201 are hinged through the first connecting head 202 and the second connecting head 203, thereby forming a triangular structure between the two adjacent first intersecting rods 201, which increases the stability of the folding unit after it is unfolded.

[0043] It should be noted that, taking the connection state of two opposing first connecting tubes 202 and second connecting tubes 203 within a folding unit as an example, the specific connection state of the first cross member 201 and the second cross member 209 is as follows:

[0044] Firstly: One end of the first connecting rod 2011 and one end of the third connecting rod 2091 are hinged to the second connecting head 203, and one end of the second connecting rod 2012 and one end of the fourth connecting rod 2092 are hinged to the first connecting head 202;

[0045] Secondly: one end of the first connecting rod 2011 and one end of the fourth connecting rod 2092 are hinged to the second connecting head 203, and one end of the second connecting rod 2012 and one end of the third connecting rod 2091 are hinged to the first connecting head 202.

[0046] Furthermore, both the first connecting head 202 and the second connecting head 203 have four hinge positions, which are located on two vertical planes. Both ends of the first cross member 201 have two first connecting ends, and the two opposite first connecting ends of two adjacent first cross members 201 are respectively hinged to the two hinge positions of the first connecting head 202 and the second connecting head 203 on the same vertical plane. Both ends of the second cross member 209 have two second connecting ends, and the two opposite second connecting ends of two adjacent second cross members 209 are respectively hinged to the two hinge positions of the first connecting head 202 and the second connecting head 203 on another vertical plane.

[0047] The hinge openings of the first connecting head 202 and the second connecting head 203 are arranged facing each other, so that when the first cross rod 201 and the second cross rod 209 are folded, the first connecting head 202 and the second connecting head 203 move away from each other. During the unfolding or retracting process, only one set of the first connecting head 202 and the second connecting head 203 needs to be pushed to move relative to each other or in opposite directions to realize the overall movement of the display rack 2. The operation is convenient and does not require complicated steps to adjust the position of each component separately, which effectively reduces the unfolding or retracting time of the display rack 2. At the same time, when the display rack 2 is unfolded or retracted, the included angles of multiple first cross rods 201 and second cross rods 209 change synchronously, so that the support force at each position of the display rack 2 is the same after unfolding, which can effectively play the role of distributing external forces and further improve the stability of the display rack 2.

[0048] In order to form an arc-shaped support member by multiple first cross members 201, after the first cross member 201 is unfolded, the included angle between the two first connecting ends that are hinged to the first connecting head 202 is smaller than the included angle between the two first connecting ends that are hinged to the second connecting head 203.

[0049] Of course, the size of the included angle mentioned above is determined by the hinge position provided on the first connecting head 202 and the second connecting head 203.

[0050] Furthermore, both first connecting ends of the first cross member 201 located at both ends of the arc-shaped support member are hinged with feet 208, so that the first cross member 201 does not directly contact the ground, but directly contacts the ground through the feet 208. The feet 208 can also be provided with fixing holes, and the position of the feet 208 relative to the ground is fixed by passing a pin through the fixing holes, thereby fixing the position of the first cross member 201.

[0051] Please see Figure 3 and Figure 4 The locking member described above connects a first connecting head 202 and a second connecting head 203 that are disposed opposite to each other. The locking member includes a locking rod 204 connected to the first connecting head 202. The locking rod 204 is provided with a locking buckle 205. It also includes a hook 206 installed on the second connecting head 203. The locking buckle 205 is fastened to the hook 206 to lock the relative position of the first connecting head 202 and the second connecting head 203.

[0052] In this embodiment, only two locking elements are provided in a set of folding units, and the two locking elements are symmetrically arranged relative to the folding units. The setting position of the locking elements can be selected according to actual needs, with the height that is most convenient for the user to manually control being the optimal position.

[0053] When the folding unit is unfolded, the locking buckle 205 is manually controlled to connect the locking buckle 205 to the hook 206, thereby restricting the position of the first connecting head 202 and the second connecting head 203, so that the first connecting head 202 and the second connecting head 203 will not be displaced relative to each other, thus locking the unfolded state of the folding unit. At the same time, in conjunction with the connection relationship of the first cross member 201 and the second cross member 209 in this embodiment, locking the position of one set of first connecting head 202 and second connecting head 203 can lock the position of all other first connecting head 202 and second connecting head 203 on a folding unit.

[0054] Please see Figure 3 , Figure 5 , Figures 6-8 After the folding unit is unfolded, guide wheels 207 are rotatably installed on opposite ends of the first connecting head 202 and the second connecting head 203 located at its upper end. The rope 215 arranged along the lateral unfolding direction of the multiple folding units passes around the first connecting head 202 and the second connecting head 203 on the multiple folding units in sequence, and the two ends of the rope 215 are connected to the hoisting mechanism installed on the first connecting head 202.

[0055] In this embodiment, the hoisting mechanism and guide wheel 207 are preferably installed at the first connecting head 202 and the second connecting head 203 in the middle. This is mainly to ensure that the force on both sides of the folding unit is uniform during the unfolding process, so as to increase the smoothness of unfolding.

[0056] Furthermore, the hoisting mechanism includes a mounting bracket 212 mounted on the first connecting head 202 and a reduction motor 210 mounted on the mounting bracket 212. The output end of the reduction motor 210 is fixed with a reel 211 connected to the end of the rope 215.

[0057] When the display rack 2 is in the folded state, the first connecting head 202 and the second connecting head 203 are at their farthest distance. When it needs to be unfolded, the geared motor 210 works to drive the roller 211 to rotate. When the roller 211 rotates, it winds up the rope 215. Under the action of the rope 215, the first connecting head 202 and the second connecting head 203 on multiple folding units move towards each other, so that multiple second cross rods 209 unfold synchronously. At the same time, the first cross rods 201 also unfold, so as to realize the automatic unfolding of the display rack 2.

[0058] In particular, to improve the uniformity of force on the first connecting head 202 and the second connecting head 203 of the rope 215 during the unfolding of the lowering and retracting frame 2, and at the same time reduce the load on the reduction motor 210, preferably, there are two winch mechanisms, located at both ends of the lowering and retracting frame 2.

[0059] It should be further explained that a connecting pin 214 is rotatably mounted on the mounting bracket 212, and a connecting rod 213 is rotatably mounted on both the first connecting rod 2011 and the second connecting rod 2012 connected to the first connecting head 202. A strip-shaped through groove 2131 is formed on the connecting rod 213 for the connecting pin 214 to pass through, and the connecting pin 214 can move relative to the length direction of the strip-shaped through groove 2131.

[0060] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0061] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
