[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0030] Referring to Figures 1 - 3 , an embodiment provided by the present utility model: a conveniently detachable flat fork guard for an electric vehicle, including a main board 1. The inner wall of the bottom end of the main board 1 is fixedly connected with a round tube 2. The inner wall of the top end of the round tube 2 is fixedly connected with a fixed block 3. The fixed block 3 mainly functions to connect the return spring 4. The return spring 4 can be compressed by the cooperation of the fixed block 3 and the moving tube 5. The top end of the fixed block 3 is elastically connected with a moving tube 5 through the return spring 4. A positioning mechanism is arranged inside the moving tube 5. The outer wall of the moving tube 5 is hinged with a limit block 9 through a hinge rod 8. An L-shaped groove 10 is opened on the outer wall of the round tube 2. The L-shaped groove 10 has a vertical opening and a horizontal opening. When the vertical opening coincides with the protrusion of the rotating plate 7, the rotating plate 7 can drive the moving tube 5 to move upward. When the horizontal opening coincides with the protrusion of the rotating plate 7, the rotating plate 7 cannot drive the moving tube 5 to move. An installation tube 11 is arranged at the bottom end of the main board 1. There is a threaded hole at the bottom end of the installation tube 11. Bolts can be passed through the inside of the installation tube 11 to be threadedly fixed to the flat fork plate on the electric vehicle, so that the installation tube 11 is installed on the flat fork plate to cooperate with the round tube 2 and the limit block 9 to fix the main board 1. The two sides of the left end of the main board 1 are respectively in contact with a right side plate 12 and a left side plate 13. The main board 1, the right side plate 12 and the left side plate 13 form the entire cross guard, which can shield the flat fork part of the vehicle. A connection component is arranged on the outer wall of the right side plate 12.
[0031] Reference Figures 1 - 2 , the connecting component includes an insertion block 14, the insertion block 14 is fixedly connected to the outer wall of the right side plate 12, a sleeve block 15 is inserted on the outer wall of the insertion block 14, and threaded holes are provided on both the insertion block 14 and the sleeve block 15, facilitating the subsequent threaded fixation by the fastening bolt 16 passing through. The insertion block 14 and the sleeve block 15 are fixedly connected by the fastening bolt 16. A positioning block 18 is fixedly connected to the bottom inner wall of the right side plate 12. The cooperation between the positioning block 18 and the positioning sleeve 17 ensures the connection stability between the main board 1, the right side plate 12 and the middle part of the left side plate 13. The outer wall of the positioning block 18 is inserted with a positioning sleeve 17. The sleeve block 15 is fixedly connected to the outer wall of the main board 1, and the positioning sleeve 17 is fixedly connected to the bottom inner wall of the main board 1.
[0032] Reference Figures 2 - 4 , the top end of the fixed block 3 is fixedly connected to one end of the return spring 4. At this time, the return spring 4 is in a compressed state. During reset, the elastic force of the return spring 4 is used to drive the moving tube 5 to reset. The other end of the return spring 4 is fixedly connected to the bottom inner wall of the moving tube 5. The outer wall of the moving tube 5 is hinged to one end of the hinge rod 8. Since the length of the hinge rod 8 is fixed, when the moving tube 5 drives one end of the hinge rod 8 to move upward, it will cause the hinge rod 8 to drive the limiting blocks 9 to approach each other. On the contrary, when the moving tube 5 drives one end of the hinge rod 8 to move downward, it will cause the hinge rod 8 to drive the limiting blocks 9 to separate from each other. The other end of the hinge rod 8 is hinged to the side wall of the limiting block 9. The limiting block 9 penetrates and is slidably connected to the inner wall of the circular tube 2. The positioning mechanism includes a rotating plate 7, the rotating plate 7 is rotatably connected to the inner wall of the moving tube 5. The outer wall of the rotating plate 7 has a convex part, and the convex part is the same size as the L-shaped groove 10. The outer wall of the rotating plate 7 is elastically connected to the moving tube 5 through a torsion spring 6. The outer wall of the rotating plate 7 is fixedly connected to one end of the torsion spring 6. At this time, the torsion spring 6 is in an initial state. According to Figure 4 and Figure 3 shown, when the rotating plate 7 on the right circular tube 2 rotates counterclockwise, it will compress the torsion spring 6. During reset, the torsion spring 6 will drive the rotating plate 7 to reset. The other end of the torsion spring 6 is fixedly connected to the inner wall of the moving tube 5. A notch for placing the torsion spring 6 is provided on the inner wall of the moving tube 5. The rotating plate 7 is clamped on the inner wall of the L-shaped groove 10. The outer wall of the rotating plate 7 is in contact with the inner wall of the circular tube 2. The outer diameter of the rotating plate 7 is the same as that of the inner wall of the circular tube 2, enabling the moving tube 5 to move vertically in the circular tube 2 through the rotating plate 7, and the moving trajectory will not deviate. The limiting block 9 is inserted into the inner wall of the mounting tube 11. Slots corresponding to the limiting block 9 are provided on both sides of the mounting tube 11 to complete the connection between the circular tube 2 and the mounting tube 11 after the insertion. The circular tube 2 is inserted into the inner wall of the mounting tube 11.
[0033] Working principle: First, when the main board 1, the right side plate 12 and the left side plate 13 need to be installed on the flat fork, since the limiting block 9 exposes the outer wall of the circular tube 2 at this time, the circular tube 2 cannot be inserted into the mounting tube 11. According to Figure 3 andFigure 4 Operate the right circular tube 2 as shown. At this time, contact the rotating plate 7 by hand and rotate the rotating plate 7 counterclockwise to compress the torsion spring 6, so that the protruding part of the rotating plate 7 is separated from the horizontal opening of the L-shaped groove 10, and the protruding part of the rotating plate 7 coincides with the vertical opening of the L-shaped groove 10. Then slowly release the rotating plate 7. Since the reset spring 4 is in a compressed state initially, the reverse elastic force of the reset spring 4 at this time will push the moving tube 5, the rotating plate 7 and the hinge rod 8 upward, so that the protruding part of the rotating plate 7 coincides with the vertical opening of the L-shaped groove 10. Use the vertical opening to block the rotating plate 7 so that it cannot rotate and reset by using the torsion spring 6. When the hinge rod 8 moves upward, it will make the hinge rod 8 drive the limit block 9 into the inside of the circular tube 2. Subsequently, align and insert the circular tube 2 with the installation tube 11. When the limit block 9 and the notch of the installation tube 11 coincide, press the rotating plate 7 by hand to drive the moving tube 5 and the hinge rod 8 to move downward. After the rotating plate 7 and the horizontal opening of the L-shaped groove 10 coincide, apply force clockwise by hand and drive the protruding part of the rotating plate 7 to rotate to the horizontal opening of the L-shaped groove 10 through the reverse elastic force of the torsion spring 6. The downward movement of the hinge rod 8 will push the limit block 9 to insert the limit block 9 into the notch of the installation tube 11 to complete the installation of the main board 1.
[0034] During the use of the device, the reverse elastic force of the reset spring 4 will continuously resist the protruding part of the rotating plate 7 in the horizontal opening of the L-shaped groove 10, and use the elastic force of the torsion spring 6 to ensure that when the device vibrates, the rotating plate 7 remains in the initial state unchanged. When disassembling and assembling the main board 1, just operate according to the above steps in the first paragraph.
[0035] When the left side plate 13 or the right side plate 12 is damaged, just twist the fastening bolt 16 to release the fixation of the sleeve block 15 and the insertion block 14, and then separate the insertion block 14 and the sleeve block 15. During the separation process, the positioning block 18 and the positioning sleeve 17 will also be separated. When installation is needed, just insert the insertion block 14 and the sleeve block 15 and fix them through the fastening bolt 16. The positioning block 18 and the positioning sleeve 17 will also be inserted to provide certain support for the main board 1 and the right side plate 12. If the main board 1 is damaged, the left side plate 13 and the right side plate 12 can still be used, reducing the replacement cost of the whole device.
[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
