[0002] At present, electric wheelchairs bring great convenience to people with mobility difficulties; electric wheelchairs mainly consist of a controller, a motor, a power source, a frame, front and rear wheels, etc. The user manipulates the forward and backward movement and steering of the wheelchair by operating the controller, and the controller is usually set at the front end of the armrest for the convenience of the rider to operate it. However, for some special groups of people, they cannot use the controller frequently or cannot use it at all. At this time, they need the caregiver to assist in pushing. However, the controller is set at the front end of the armrest, which is not convenient for the caregiver to operate, bringing a large workload to the caregiver. Therefore, how to facilitate the caregiver to assist in pushing has become an urgent technical problem to be solved. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide an integrated hand-push assisted control device with a simple structure design, convenient operation and good controllability.

[0004] To solve the above technical problem, the integrated hand-push assisted control device of the utility model includes two backrest tubes arranged on the back of the wheelchair and a U-shaped push tube formed by a cross beam tube and insertion tubes bent on both sides of the cross beam tube. The U-shaped push tube can be inserted into the two backrest tubes as an auxiliary push handle. An installation groove is opened on the upper side of the middle part of the U-shaped push tube, and an auxiliary control mechanism with an operation panel is installed in the installation groove. The auxiliary control mechanism is fixedly installed in the installation groove and makes the operation panel located on the top surface of the auxiliary push handle.

[0005] The auxiliary control mechanism further includes a control circuit board matched with the operation panel. The control circuit board is arranged in the installation groove and can make the operation panel located on the top surface of the auxiliary push handle.

[0006] The auxiliary control mechanism further includes a panel bracket. The control circuit board is fixedly installed on the bottom surface of the panel bracket through fasteners, and the operation panel is fixedly installed on the top surface of the panel bracket.

[0007] A plurality of operation holes are arranged on the panel bracket, and a plurality of operation buttons are arranged on the control circuit board. The operation buttons pass through the operation holes and extend into the operation positions of the operation panel.

[0008] A stepped surface is arranged in the installation groove, and the panel bracket and the control circuit board are fixedly installed on the stepped surface.

[0009] The operation panel is snap-fitted and fixed outside the panel bracket and limited by the stepped surface.

[0010] A locking hole is provided on the backrest tube, and a locking knob capable of locking the U-shaped push tube and the backrest tube is screwed into the locking hole.

[0011] The advantages of the present utility model are as follows:

[0012] By arranging two backrest tubes on the back of the wheelchair and a U-shaped push tube inserted into the two backrest tubes, and at the same time, an installation groove for arranging an auxiliary control mechanism is provided on the upper side of the middle part of the U-shaped push tube. Thus, it is not only convenient for the caregiver to assist in pushing the wheelchair, but also because the auxiliary control mechanism is placed on the upper side of the middle part of the U-shaped push tube, the auxiliary control mechanism can be used for operation during the pushing process, and there is no longer a need to rely on the original operating mechanism, further saving manpower. Its structure design is very simple, and the operation and use are also very convenient, greatly reducing the labor intensity of the caregiver. In particular, the auxiliary control mechanism is composed of a control circuit board, a panel bracket, an operation panel, etc., and is installed in cooperation with the installation groove. Its installation structure design is reasonable and reliable, ensuring its stability and good controllability. In addition, the operation interface of the control panel adopts a button method to ensure that the wheelchair is always in a safe state and guarantee safety. BRIEF DESCRIPTION OF THE DRAWINGS
