The mounting base of the invention is movably mounted together with two mounting blocks via a connecting shaft, which can facilitate the folding function of the mounting base, thereby saving space. When needed, the sleeve block is sleeved into the circular hole of the connecting block to achieve the support use of the mounting base.

[0057] like Figure 1-9 As shown, the method for using the child seat includes the following contents:

[0058] (1) Riding: When riding, according to the riding needs of the passenger, the fixing rod 41 of the lying protection mechanism 4 is adjusted to a suitable angle with the support rod 21 of the riding mechanism 2 through the second connecting component 5; when the passenger rides, the bolt of the second connecting component 5 is loosened to loosen the connection position of the No. 3 gear tube clamp 51 and the No. 1 gear clip 52, and the fixing rod 41 is rotated on the vertical plane through the No. 3 gear tube clamp 51, and the fixing rod 41 is adjusted to form a right angle with the support rod 21, and the bolt is tightened; when the passenger needs to lie down, the fixing rod 41 is rotated backward on the vertical plane through the No. 3 gear tube clamp 51, and the fixing rod 41 and the support rod 21 are adjusted to form an obtuse angle of a certain angle, so that the passenger can lie down at this angle in the lying protection mechanism 4.

[0059] Since the space in the footrest area of the electric vehicle is limited and the rotation angle of the fixing rod 41 is small, the bolts of the first connecting assembly 3 can be loosened to loosen the clamping part of the No. 1 gear pipe clamp 31, and the support rod 21 can be rotated a certain angle on the horizontal plane based on the fixing rod 41, so that the riding mechanism 2 and the lying protection mechanism 4 can be rotated out of the footrest area to obtain a larger space, and the fixing rod 41 can be rotated backward to a larger angle, so that the passenger can obtain a larger lying angle and improve comfort.

[0060] To ensure safety during riding, when the support rod 21 is rotated, the maximum rotation angle of the support rod 21 should ensure that the protection frame 42 of the lying protection mechanism 4 does not exceed the length range of the electric vehicle handlebar, and the protection frame 42 of the lying protection mechanism 4 is located under the driver's arms and above the thighs, so that the driver's arms and thighs can protect the passengers during driving.

[0061] In order to facilitate the driver to get on the vehicle after adjustment, the support rod 21 should be rotated to the right.

[0062] (2) Folding: After riding, first rotate the fixed rod 41 of the lying protection mechanism 4 to the maximum angle through the second connecting component 5 toward the riding mechanism 2, so that the lying protection mechanism 4 is folded. The specific method is: loosen the bolt of the second connecting component 5 to loosen the connection position of the No. 3 gear pipe clamp 51 and the No. 1 gear clip 52, and rotate the fixed rod 41 toward the riding mechanism 2 to rotate the fixed rod 41 to the maximum angle, tighten the bolt, and fold the lying protection mechanism 4.

[0063] The support rod 21 of the riding mechanism 2 is rotated around the axis of the first connecting component 3 until the seat cushion 22 is in a vertical state. At the same time, the riding mechanism 2 is rotated to the maximum angle toward the front of the electric vehicle through the first connecting component 3 to fold the riding mechanism 2. The specific method is: loosen the bolts of the first connecting component 3, so that the clamping parts of the No. 1 gear tube clamp 31 and the No. 2 gear tube clamp 32 loosen the mounting rod 11 and the support rod 21 respectively, and loosen the connection position of the No. 1 gear tube clamp 31 and the No. 2 gear tube clamp 32. First, rotate the support rod 21 around the axis of the support rod 21 in the clamping part of the No. 2 gear tube clamp 32 until the seat cushion 22 is in a vertical state, and then rotate the support rod 21 to the maximum angle on the horizontal plane toward the front of the vehicle based on the mounting rod 11 through the No. 1 gear tube clamp 31, and tighten the bolts to fold the riding mechanism 2.

[0064] Finally, the support mechanism 6 is rotated to the maximum angle toward the riding mechanism 2 through the third connecting component 7, so that the support mechanism 6 is folded. The specific method is: the load-bearing rod 61 is rotated to the maximum stroke toward the riding mechanism 2 based on the pin shaft 73 through the connecting piece 72. At this time, the spring 81 will tighten the load-bearing rod 61 to prevent the load-bearing rod 61 from rotating backward, thereby completing the folding of the support mechanism 6.

[0065] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
