Embodiment 1
[0021] Please refer to Figures 1-4As shown in the figure, the present invention is an electric bicycle folding front shield, including a housing, characterized in that: the housing includes a front cover 3 and a rear cover 4, the front cover 3 and the rear cover 4 are rotatably connected, and a mounting bracket 5 is fixedly installed on one side of the rear cover 4. The rear cover 4 can be fixedly installed on the front side of the electric bicycle through the mounting bracket 5. A folding mechanism is installed on the other side of the rear cover 4. The folding mechanism can be rotated and folded to expand into a rectangular frame structure or rotated and folded to contract on the side of the rear cover 4. A flexible windshield film 1 that can be expanded or folded and contracted is installed on the folding mechanism. When the front shield is in use, first rotate the front cover 3 forward to open it, then expand the folding bracket. At the same time, the folding bracket drives the flexible windshield film 1 to expand and supports the flexible windshield film 1, so that the flexible windshield film 1 after expansion can be used for blocking and protection, playing a role in preventing wind and sand and rain, and improving the riding comfort. When riding in dangerous weather such as strong winds, the folding bracket and the flexible windshield film 1 can be folded and stored on one side of the rear cover 4, and then the front cover 3 and the rear cover 4 are closed, so as to prevent the flexible windshield film 1 from being affected by the wind force and affecting the riding stability of the electric bicycle, and improving the riding stability and safety of the electric bicycle.
[0022] Specifically, the folding mechanism includes a support cross bar 7 and a main mechanism cross beam 27. Upper support rods 8 are rotatably installed at both ends of the support cross bar 7. The bottom end of the upper support rod 8 is rotatably connected to a lower support rod 9 through a joint connector. The bottom end of the lower support rod 9 is rotatably installed at the end of the main mechanism cross beam 27. The main mechanism cross beam 27 is installed inside the rear cover 4. When the folding bracket is expanded, the upper support rod 8 and the lower support rod 9 are in a straight line state. At this time, a frame structure is formed among the support cross bar 7, the two groups of upper support rods 8 and the lower support rods 9, and the main mechanism cross beam 27, and the flexible windshield film 1 is supported, so that the flexible windshield film 1 can be stably installed at the front end of the electric bicycle. When it is necessary to fold and store the folding bracket and the flexible windshield film 1, the connection parts of the two groups of upper support rods 8 and the lower support rods 9 are rotated and folded inward, so that the upper support rod 8 and the lower support rod 9 are folded to a state close to parallel, and the support cross bar 7 can gradually descend as the upper support rod 8 and the lower support rod 9 are folded, so that the support cross bar 7, the upper support rod 8 and the lower support rod 9 are folded and stored on one side of the rear cover 4.
[0023] Specifically, the joint connector includes an upper connecting ear 17 and a lower connecting ear 21. The upper connecting ear 17 is fixedly installed at the bottom end of the upper support rod 8. An upper connecting shaft 18 is rotatably installed on the upper connecting ear 17. The lower connecting ear 21 is fixedly installed at the top end of the lower support rod 9. A lower connecting shaft 20 is rotatably installed at the top end of the lower connecting ear 21. A connecting piece 19 is rotatably installed between the upper connecting shaft 18 and the lower connecting shaft 20. Through the cooperation of the upper connecting ear 17, the upper connecting shaft 18, the connecting piece 19, the lower connecting shaft 20 and the lower connecting ear 21, the rotational connection between the upper support rod 8 and the lower support rod 9 can be realized, so as to facilitate the rotation and expansion or folding between the upper support rod 8 and the lower support rod 9.
[0024] Specifically, a positioning sleeve 12 is slidably sleeved on the outer circle of the upper support rod 8. A pin hole 15 is opened at the upper end of the positioning sleeve 12. An upper elastic pin 14 capable of being inserted into the pin hole 15 is installed on one side of the upper support rod 8. A pin 16 capable of supporting and limiting the bottom end of the positioning sleeve 12 is installed on one side of the lower support rod 9. Among them, when the upper support rod 8 and the lower support rod 9 are in a folded state, the positioning sleeve 12 is fixedly limited on the surface of the upper support rod 8 through the pin connection of the upper elastic pin 14 and the pin hole 15. When the upper support rod 8 and the lower support rod 9 are unfolded into a straight line state, the upper elastic pin 14 is pressed inward to contract, releasing the limit on the positioning sleeve 12. Then, the positioning sleeve 12 is slid downward until the bottom end of the positioning sleeve 12 abuts against the top surface of the pin 16. At this time, the positioning sleeve 12 limits and locks the connection between the upper support rod 8 and the lower support rod 9, enabling the upper support rod 8 and the lower support rod 9 to maintain a stable connection and increasing the supporting force after the folding bracket is unfolded.
[0025] Specifically, the flexible wind shield film 1 is a PVC transparent film. An adhesive structure 6 capable of bonding with each other is installed on the flexible wind shield film 1 and the folding mechanism. The adhesive structure 6 is a magic tape or a magnet or a magnetic buckle. The flexible wind shield film 1 is connected to the folding bracket through the adhesive structure 6, which is convenient for the disassembly and replacement of the flexible wind shield film 1.
[0026] Specifically, fiberglass strips 2 are respectively installed inside the adhesive structures 6 along the upper and lower edges of the flexible wind shield film 1 in a segmented manner. The segmented fiberglass strips 2 play a role in reducing the folding size, expanding the width outside the rectangular frame size, and supporting the transparent film.
[0027] Specifically, a zipper capable of engaging with each other is installed at the openings of the front cover 3 and the rear cover 4, and zipper heads are installed at both ends of the zipper. The front cover 3 and the rear cover 4 can be closed and sealed through the zipper. Zipper heads are provided at both ends of the zipper. When the folding bracket and the flexible wind shield film 1 are unfolded, the two zipper heads can be used to close the zippers at both ends first, so that the two ends of the front cover 3 and the rear cover 4 are in a closed connection state. Thus, during the practical use of the unfolded flexible wind shield film 1, the front cover 3 and the rear cover 4 can also be in a butt-joint connection state, which can not only protect the components inside the rear cover 4, but also fix the front cover 3 to prevent the front cover 3 from shaking.
[0028] Specifically, a limit pull rod pin 13 is threadedly fixedly installed at the lower end of the lower support rod 9, and a locking hand-tightening bolt 11 is threadedly fixedly installed at the lower end of the lower support rod 9, which can abut and lock the lower support rod 9 against the main mechanism cross beam 27. An arc-shaped guide groove 10 is provided on the main mechanism cross beam 27 for the locking hand-tightening bolt 11 to slide; when the lower support rod 9 is rotated, folded or unfolded, it can drive the locking hand-tightening bolt 11 to slide along the arc-shaped guide groove 10, so as to limit the lower support rod 9 through the cooperation of the locking hand-tightening bolt 11 and the arc-shaped guide groove 10, thereby improving the stability of the movement of the lower support rod 9, and when the lower support rod 9 is rotated and unfolded, the locking hand-tightening bolt 11 is tightened so that the locking hand-tightening bolt 11 abuts against the surface of the main mechanism cross beam 27, thereby abutting and locking the lower support rod 9, improving the stability of the lower support rod 9 when it is unfolded. At the same time, the limit pull rod pin 13 is rotated forward and inserted into the positioning hole on the main mechanism cross beam 27 to further position the lower support rod 9. Embodiment 2
[0029] See also Figures 4-8 As shown, the difference between this embodiment and the above embodiment is that the joint connection member includes a hinge 22, and the two hinge pieces of the hinge 22 are fixedly mounted on the upper support rod 8 and the lower support rod 9 respectively; Among them, the hinge 22 is installed on the outer side or front and rear sides of the upper support rod 8 and the lower support rod 9, and is used to rotatably connect the upper support rod 8 and the lower support rod 9, so as to facilitate the upper support rod 8 and the lower support rod 9 to rotate, fold or unfold.
[0030] Specifically, an inner support rod 24 is slidably inserted inside the lower support rod 9, and an interval sliding guide groove 23 corresponding to the inner support rod 24 is opened on one side of the lower support rod 9. A toggle key 25 extending to the outside of the interval sliding guide groove 23 is fixedly installed on one side of the inner support rod 24, and a limit elastic pin 26 that can slide and engage with the interval sliding guide groove 23 is also installed; Among them, when the upper support rod 8 and the lower support rod 9 are in the folded state, the inner support rod 24 is located on the inner side of the lower support rod 9, and the limiting elastic pin 26 shrinks and abuts on the inner wall of the lower support rod 9. When the upper support rod 8 and the lower support rod 9 are unfolded in a straight line, the inner support rod 24 is pushed upward by the toggle key 25, so that the upper end of the inner support rod 24 is inserted into the upper support rod 8, and at this time the toggle key 25 abuts against the top of the interval sliding guide groove 23, and the limiting elastic pin 26 abuts against the bottom end of the interval sliding guide groove 23, so that the inner support rod 24 is positioned through the cooperation of the toggle key 25, the limiting elastic pin 26 and the interval sliding guide groove 23, so that the inner support rod 24 is inserted into the connection between the upper support rod 8 and the lower support rod 9, so that the upper support rod 8 and the lower support rod 9 maintain a stably connected connection, thereby increasing the supporting force after the folding bracket is unfolded.
