Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 This utility model provides an embodiment of an electric motorcycle charging port cover mounting structure, including a housing 1 and a protective cover 2. The front of the housing 1 and the back of the protective cover 2 are hinged. A fastening bolt 18 is provided inside the housing 1, and the housing 1 is installed on the body of the electric motorcycle by means of the fastening bolt 18. A charging port 3 is provided inside the housing 1, and a cable and a charging connector are provided on the rear side of the charging port 3 to provide support for charging. This is the prior art. A pressing mechanism 10 is provided inside the protective cover 2. The pressing mechanism 10 includes a pressing ring 101 and a sealing gasket 102.

[0032] Reference Figure 2 , Figure 3 , Figure 5 The sealing gasket 102 is disposed on the rear side of the protective cover 2. The back of the sealing gasket 102 contacts the front of the charging port 3. The extrusion ring 101 is fixedly connected to the inner wall of the protective cover 2. A connecting block 103 is fixedly connected to the inner wall of the extrusion ring 101. The surface of the sealing gasket 102 is provided with a connecting groove 104 that cooperates with the connecting block 103. The connecting block 103 is slidably connected to the inner wall of the connecting groove 104. The sliding direction of the connecting block 103 is the axial direction of the extrusion ring 101.

[0033] Reference Figure 2 , Figure 3 , Figure 5 The connecting block 103 has a groove 106 inside. A protrusion 105 with a rectangular cross-section is fixedly connected to the inner wall of the connecting groove 104. The protrusion 105 is slidably connected to the inner wall of the groove 106. The sliding direction of the protrusion 105 is the axial direction of the extrusion ring 101. The protrusion 105 is elastically connected to the inner wall of the groove 106 through a compression spring 107. By setting the compression spring 107, a spring force is applied to the protrusion 105 and the sealing gasket 102 in the direction close to the charging port 3. When the protective cover 2 is closed, the sealing gasket 102 can be pressed tightly against the surface of the charging port 3. The protective cover 2 has a fixing mechanism 11 inside.

[0034] Reference Figures 2-4 The fixing mechanism 11 includes a limiting block 111, which is fixedly connected to the inner wall of the housing 1. The left side of the limiting block 111 is provided with an inclined surface. The fixing mechanism 11 also includes a control plate 114, which is slidably connected to the front of the protective cover 2. The sliding direction of the control plate 114 is left and right. The back of the control plate 114 is fixedly connected to a connecting plate 113. The left side of the connecting plate 113 is elastically connected to the inner wall of the protective cover 2 through a return spring 115. The return spring 115 applies a rightward elastic force to the connecting plate 113, the control plate 114, and the wedge 112. The back of the connecting plate 113 is fixedly connected to the wedge 112, which is provided with an inclined surface on the right side. The projections of the wedge 112 and the limiting block 111 on the front coincide. Through the cooperation of the wedge 112 and the limiting block 111, the protective cover 2 will not open arbitrarily when closed, thereby maintaining the sealing performance of the sealing gasket 102.

[0035] Working principle: When in use, first fix the housing 1 to the body of the electric motorcycle with fastening bolts 18 to ensure that the position of the charging port 3 is accurate and stable. When it is necessary to charge the electric motorcycle, operate the protective cover 2 to open the charging port 3. Manually slide the control plate 114 on the front of the protective cover 2 to the left, which will drive the connecting plate 113 and the wedge 112 to move to the left together. As the control plate 114 moves to the left, the wedge 112 gradually separates from the limiting block 111 until the wedge 112 is completely separated from the limiting block 111, releasing the locking relationship between the two. At this time, the protective cover 2 can be rotated open around its hinge point with the housing 1 to expose the charging port 3 and prepare for charging operation.

[0036] After charging is complete, rotate the protective cover 2 back to its original position around the hinge point, bringing it close to the housing 1. During this process, the sealing gasket 102 begins to contact the surface of the charging port 3 and is subjected to the initial pressure of the compression ring 101. As the protective cover 2 continues to close, the right inclined surface of the wedge 112 contacts and presses against the left inclined surface of the limiting block 111, forcing the wedge 112 to temporarily move to the left until the wedge 112 completely slides past the projection area of ​​the limiting block 111. Then, under the action of the return spring 115, the wedge 112 returns to the right side and locks into the rear side of the limiting block 111, forming a stable locking state.

[0037] When the protective cover 2 is closed and the sealing gasket 102 begins to contact the surface of the charging port 3, the compression spring 107 applies a spring force to the protrusion 105 in the direction of the charging port 3, so that the sealing gasket 102 fits tightly against the surface of the charging port 3, ensuring a good sealing effect and preventing moisture and dust from entering the interior of the charging port 3, thereby protecting the charging interface from the influence of the external environment.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
