[0001] This application is a divisional application of patent application No. 2017106792915 with a filing date of August 10, 2017. TECHNICAL FIELD

[0002] The present application relates to a foldable tent. BACKGROUND

[0003] Tents have various structural forms, and the tent used for outdoor sunshade is usually a foldable tent. The traditional foldable tent has a small sunshade area. In order to increase the sunshade area of the tent after being unfolded, a roof tent with a roof structure appears, and an extended eave rod is arranged at the top corner of the tent. The purpose of increasing the area is achieved by arranging a surrounding edge on the eave rod. The main method is to pivot or insert the eave rod on the top rod of the top support of the tent. The outer end of the eave rod is movably arranged outside the stand column. However, in the current foldable tent, the eave rod is independently arranged relative to the main support of the tent. When unfolding or folding, it needs to be operated in two steps. That is, when unfolding, the main support of the tent is unfolded first, and then each eave rod is pried open or pulled out. Since the eave rod is at a high position, it is not convenient to operate. When folding, the problem is the same. Therefore, the existing foldable tent has the problems of complex structure, cumbersome and inconvenient operation. SUMMARY

[0004] To solve the above technical problems, the present application provides a foldable tent, which has a larger sunshade area and the eave rod can be unfolded and folded with the first top rod, which is convenient to operate.

It should be noted that the description of the embodiments is intended to help understand the present application, but is not intended to limit the present application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0041] The present embodiment provides a foldable tent with eaves, which has a large sun-shading area. Referring to the drawings, Figures 1-14 The foldable tent comprises at least three column assemblies 1, roof rod assemblies 2 corresponding to the number of column assemblies 1, and side rod assemblies 3 connected between the upper ends of any two adjacent column assemblies 1. In the present embodiment, the number of column assemblies 1 is four, which are arranged at equal intervals to form a cubic space, and the column assemblies 1 extend generally in the vertical direction to support the tent on the ground. The number of roof rod assemblies 2 is also four, which are used to form the top frame of the tent. The number of side rod assemblies 3 is also four, which are respectively located at the front, rear, left and right of the tent.

[0042] Reference is made to the accompanying drawings Figure 2 As shown in FIG. 1, each of the pole assemblies 2 comprises, in order from inside to outside, a first pole 21, a second pole 22 and a cornice pole 23, each having an inner end and an outer end. The terms "inside" and "outside" and the like as used herein are defined with reference to the vertical center line of the tent, with the inside being closer to the vertical center line of the tent and the outside being farther away from the vertical center line of the tent. The inner ends of the four first poles 21 of the four pole assemblies 2 are pivotally connected to an upper center connector 41, so that the four pole assemblies 2 form a cross-shaped structure extending along the diagonals of the tent frame to the four corners of the tent and are pivotable relative to each other. In each of the pole assemblies 2, the outer end of the first pole 21 and the inner end of the second pole 22 are pivotally connected, and the outer end of the second pole 22, the inner end of the cornice pole 23 and the upper end of the corresponding upright assembly 1 are pivotally connected to each other. In other words, the outer end of the second pole 22, the inner end of the cornice pole 23 and the upper end of the corresponding upright assembly 1 are pivotally connected to each other by two pivots or by the same pivot, for example, the outer end of the second pole 22 and the inner end of the cornice pole 23 are pivotally connected by one pivot, and the upper end of the corresponding upright assembly 1 is pivotally connected to one of the outer end of the second pole 22 and the inner end of the cornice pole 23 by another pivot. In the present embodiment, the outer end of the second pole 22 and the inner end of the cornice pole 23 are pivotally connected to the upper end of the corresponding upright assembly 1 by the same pivot.

[0043] Each of the pole assemblies 2 further comprises a transmission member connected between the first pole 21 and the cornice pole 23 for unfolding or folding the cornice pole 23 with the first pole 21. Typically, the transmission member is a transmission rod 24 pivotally connected between the first pole 21 and the cornice pole 23, and a four-bar linkage mechanism is formed between the first pole, the second pole, the cornice pole and the transmission rod, and the four rods are linked to each other to fold and unfold relative to each other.

In the embodiment, each of the side pole assemblies 3 comprises three cross brace pole members 30, wherein the upper end of the first connecting rod 31 is pivotally connected to the upper end of the column assembly 1 or the upper end of the second connecting rod 32 of another cross brace pole member 30, the lower end of the first connecting rod 31 is pivotally connected to the lower end of the second connecting rod 32 of another cross brace pole member 30 or the sliding block 51 on another column assembly 1, the lower end of the second connecting rod 32 is pivotally connected to the sliding block 51 on a column assembly 1 or the lower end of the first connecting rod 31 of another cross brace pole member 30, and the upper end of the second connecting rod 32 is pivotally connected to the upper end of the first connecting rod 31 of another cross brace pole member 30 or the upper end of another column assembly 1.

[0048] When the above-mentioned tent is folded, the locking mechanism between the upper center connecting member 41 and / or each of the first roof poles 21 is unlocked, the locking mechanism can adopt the locking mode known in the prior art, which will not be described here; the column lower section 12 of the column assembly 1 is received into the column upper section 11; the sliding block 51 on the column assembly 1 is pulled downward to drive the driving pole 52 to rotate, and the transmission pole 24 rotates accordingly, under the action of the transmission pole 24, the first roof pole 21 and the second roof pole 22 are close to each other, and the outer end of the eave pole 23 is rotated upward and inward; at the same time, with the folding of the roof pole assembly 2, the column assemblies 1 are also close to each other, so that the cross brace pole members 30 of the side pole assembly 3 are folded and close to each other; when the sliding block 51 moves to the lowest position, each of the column assemblies 1 is close to each other, each of the cross brace pole assemblies is close to each other, and each of the roof pole assemblies 2 is folded between the column assemblies 1, and the folding state of the tent is shown.
