Detailed implementation manners

[0021] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0022] The rear windshield glass opening and closing assembly of the tricycle according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0023] As Figures 1-6 shown, the rear windshield glass opening and closing assembly of the tricycle according to the embodiment of the present invention may include a fixing member 10, a first connecting member 20, a link mechanism 30 and two second connecting members 40.

[0024] Among them, the fixing member 10 is arranged on the vehicle frame (not shown in the figure), and the first connecting member 20 is arranged at the middle bottom of the rear windshield glass 50.

[0025] One end of the linkage mechanism 30 is pivotally connected to the fixing member 10, and the other end of the linkage mechanism 30 is pivotally connected to the first connecting member 20. Two second connecting members 40 are symmetrically arranged at the top of the rear windshield 50, and the two second connecting members 40 are respectively connected to the vehicle frame.

[0026] For clearly explaining the previous embodiment, in an embodiment of the present utility model, as Figures 1-5 shown, the fixing member 10 may include a fixing gasket 11 and a fixing rod 12. Among them, two symmetrically distributed nuts 101 are provided on the side wall of the fixing gasket 11. It should be noted that the nut 101 described in this embodiment is fixedly connected to the fixing gasket 11.

[0027] One end of the fixing rod 12 is provided with two symmetrically distributed first through holes 102. One ends of two first bolts (not shown in the figure) sequentially penetrate through the corresponding first through holes 102 and the vehicle frame and are threadedly connected to the nuts 101. The other end of the fixing rod 12 is provided with a groove 103, and a limiting block 104 is arranged in the groove 103.

[0028] It can be understood that the staff can effectively fix the fixing rod 12 on the vehicle frame by sequentially penetrating one ends of the two first bolts through the corresponding first through holes 102 and the vehicle frame and threadedly connecting them to the nuts 101.

[0029] Furthermore, in an embodiment of the present utility model, as Figures 1-5 shown, the first connecting member 20 may include a first nut 21 and a connecting rod 22. Among them, one end of the first nut 21 is inserted into the installation hole in the middle of the bottom of the rear windshield 50. One end of the connecting rod 22 is provided with a second through hole 201, and one end of a second bolt passes through the second through hole 201 and is threadedly connected to the first nut 21.

[0030] It can be understood that the staff can fix the connecting rod 22 on the rear windshield 50 by passing one end of the second bolt through the second through hole 201 and threadedly connecting it to the first nut 21.

[0031] Furthermore, in an embodiment of the present utility model, as Figures 1-6 shown, the linkage mechanism 30 may include a driving rod 31, an auxiliary connecting rod 32, and two pull plates 33.

[0032] Among them, a receiving groove 301 for receiving the auxiliary connecting rod 32 is provided on the driving rod 31. One end of the driving rod 31 is pivotally connected to the other end of the connecting rod 22 through a first rotating shaft (not specifically marked in the figure).

[0033] One end of the auxiliary connecting rod 32 is pivotally connected to the other end of the driving rod 31 through a second rotating shaft (not specifically marked in the figure). The other end of the auxiliary connecting rod 32 is rotatably arranged in the groove 103 through a third rotating shaft (not specifically marked in the figure). A closing anti - detachment block 302 close to the second rotating shaft is arranged on one side wall of the auxiliary connecting rod 32, and an opening anti - detachment block 303 close to the third rotating shaft is arranged on the other side wall of the auxiliary connecting rod 32. Two pull plates 33 are integrally formed on both sides of the driving rod 31.

[0034] It should be noted that in the described embodiment, the opening anti - detachment block 303 abuts against the limit block 104 when the rear windshield 50 is fully opened. It can be understood that by setting the limit block 104, the opening anti - detachment block 303 can be limited. At the same time, the center line from the center of the second rotating shaft to the center of the third rotating shaft on the auxiliary connecting rod 32 forms an opening self - locking angle of 4° with the horizontal plane. Under the action of the rotational pressure of the rear windshield 50 (since the rear windshield 50 has an inclination angle when fully opened, the rear windshield will generate a reverse flipping force under its own gravity), the reliability and stability of the self - locking of the rear windshield 50 during opening are effectively ensured.

[0035] Furthermore, in an embodiment of the present utility model, as Figures 1-3 shown, the second connecting member 40 may include a second nut 41, a fixing block 42 and a connecting piece 43. One end of the second nut 41 is inserted into the mounting hole (not specifically marked in the figure) at the top of the rear windshield 50.

[0036] The fixing block 42 is provided with a third through - hole 401. One end of the third bolt passes through the third through - hole 401 and is threadedly connected to the second nut 41. One end of the connecting piece 43 is pivotally connected to the fixing block 42 through a fourth rotating shaft, and the other end of the connecting piece 43 is fixedly connected to the vehicle frame.

[0037] Specifically, when the relevant staff needs to open the rear windshield 50 for ventilation, the staff can first pull up the driving rod 31 by holding the pull plates 33 on both sides of the driving rod 31, and then push forward (i.e., push in the direction of the rear windshield 50) and press down the driving rod 31. At this time, the driving rod drives the auxiliary connecting rod 32 to flip upward (i.e., the auxiliary connecting rod 32 flips with the hinge point between the auxiliary connecting rod 32 and the fixed rod 12 as the center of the circle), so that the auxiliary connecting rod 32 flips out of the receiving groove 301 of the driving rod 31 until the opening anti - detachment block 303 on the auxiliary connecting rod 32 abuts against the limit block 104. At this time, the auxiliary connecting rod 32 and the driving rod 31 are unfolded, thereby pushing the rear windshield 50 to flip open with the pivot point between the fixing block 42 and the connecting piece 43 as the center of the circle (see Figure 4 shown).

[0038] When the relevant staff need to close the rear windshield 50, the staff hold the pull plates 33 on both sides of the driving rod 31 and first pull up the driving rod 31, and then pull the driving rod 31 back to its original position. At this time, the auxiliary connecting rod 32 rotates under the drive of the driving rod 31 and screws into the receiving groove 301 of the driving rod 31, thereby pulling the rear windshield 50 back to its original position and closing it. At this time, the closing anti-detachment block 302 abuts against the bottom wall of the groove 103 of the fixed rod 12. At the same time, the center line from the center of the second rotating shaft to the center of the third rotating shaft on the auxiliary connecting rod 32 forms a closing self-locking angle of 52° with the horizontal plane, thus effectively ensuring the reliability and stability of the closing self-locking of the rear windshield 50 (see Figure 5 shown).

[0039] In summary, the opening and closing assembly of the rear windshield of the tricycle in the embodiment of the present invention has the advantages of miniaturization, light weight and beauty, and can effectively ensure the smoothness and stability of the opening and closing process.
