Automatic folding tent

Abstract

An automatic folding tent includes at least a plurality of main brackets, auxiliary brackets, connecting rod groups, elevation devices, and a tent cloth. After the main brackets and the auxiliary brackets are pivoted, the connecting rod groups for supporting the auxiliary brackets to unfold are disposed between the main brackets and the auxiliary brackets. The auxiliary brackets are gathered at a top block, the elevation device is disposed on a top end of the main bracket and is power-connected to the connecting rod group, and the tent cloth is wrapped on top of the main brackets and the auxiliary brackets. Accordingly, the elevation devices are controlled to synchronously operate through a remote controller, so as to actuate the main brackets to ascend and descend, and to actuate the auxiliary brackets to unfold or fold, thereby automatically operating the tent to fold and unfold.

1 . An automatic folding tent, comprising:
 a plurality of main brackets, wrapped by a case, and each having a first joint portion disposed on a top end;   a plurality of auxiliary brackets, each having one end pivoted on the first joint portion and the other end assembled on a top block, and having a second joint portion disposed thereon;   a plurality of connecting rod groups, wherein each connecting rod is connected to the main bracket and the auxiliary bracket respectively, and a connecting rod is power-connected to an elevation device, so as to drive the main bracket and the auxiliary bracket to unfold or fold;   three groups of elevation devices, disposed on the top ends of the main brackets, and each having an extensible rod disposed on a bottom end, so as to drive the main bracket to ascend and descend; and   a tent cloth, wrapped on top of the main brackets and the auxiliary brackets.   
   
   
       2 . The automatic folding tent according to  claim 1 , wherein the case of the main bracket has an elongate through hole disposed on one side, and a third connecting rod and the extensible rod are pivoted in the elongate through hole. 
   
   
       3 . The automatic folding tent according to  claim 1 , wherein a diamond crossing extensible frame is disposed between two neighboring main brackets. 
   
   
       4 . The automatic folding tent according to  claim 1 , wherein the connecting rod group has a first connecting rod, a second connecting rod, a third connecting rod, and a third joint portion, the first connecting rod, the second connecting rod, and the third connecting rod are disposed on the third joint portion, one end of the first connecting rod is disposed on the auxiliary bracket, and the second connecting rod is disposed on the main bracket. 
   
   
       5 . The automatic folding tent according to  claim 1 , wherein the extensible rod of the elevation device has a roller on a bottom end. 
   
   
       6 . The automatic folding tent according to  claim 1 , wherein the extensible rod of the elevation device is driven to extend and contract through a pneumatic element actuated by a motor. 
   
   
       7 . The automatic folding tent according to  claim 1 , wherein the extensible rod of the elevation device is driven to extend and contract through a hydraulic element actuated by a motor. 
   
   
       8 . The automatic folding tent according to  claim 1 , wherein the elevation device drives a screw rod to rotate by a motor, a sliding block is movably disposed on the screw rod, and the sliding block drives the connecting rod group to fold and unfold and to drive the extensible rod to extend and contract. 
   
   
       9 . The automatic folding tent according to  claim 1 , wherein the plurality of groups of elevation devices are information-linked to a remote controller.
