[0004] For example, the existing power connection seats for the frames of two-wheel electric vehicles as described above are all directly fixed to the corresponding positions on the frame through fastening rods. In the specific implementation process, the frame inevitably vibrates, and this vibration easily causes the fastening rods to loosen, which in turn leads to the loosening or even direct detachment of the power connection seat. Therefore, it is urgent to propose a corresponding power connection seat for the frame of a two-wheel electric vehicle to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to propose a power connection seat for the frame of a two-wheel electric vehicle in order to solve the above problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A power connection seat for the frame of a two-wheel electric vehicle includes a fixed plate and a connector that are fixedly matched. A fastening rod penetrates through the fixed plate. The outer surface of the fixed plate is fixedly connected to a connecting frame through a locking rod. The connecting frame is in a C-shaped structure. A vertically telescopic outer sleeve is provided on the inner surface of the top of the connecting frame. A pressing component for axially limiting the locking rod and the fastening rod is provided at the bottom of the outer sleeve.

[0008] Preferably, an L-shaped bracket is fixedly connected to the outer surface of the outer sleeve. The top of the vertical end of the L-shaped bracket is rotatably connected to a tab that is slidably matched with the top of the connecting frame through an elastic rotating shaft.

[0009] Preferably, a vertical bar is fixedly connected to the inner surface of the bottom of the connecting frame, the outer sleeve is sleeved outside the vertical bar, and a spring is fixedly connected between the bottom of the vertical bar and the inner surface of the bottom of the outer sleeve.

[0010] Preferably, both the vertical bar and the outer sleeve have a rectangular cross-sectional structure, and a convex tab is fixedly connected to the outer surface of the outer sleeve.

[0011] Preferably, the pressing component includes a combined plate, a rubber pad is fixedly connected to the bottom of the combined plate, and the tops of both the locking rod and the fastening rod are abutted against the bottom of the rubber pad. The bottom of the outer sleeve is snap-fitted with the top of the combined plate through a card slot.

[0012] Preferably, the bottom of the connecting frame is snap-fitted with the inner surface of the top of the fixing plate through a mating groove, and the inner surface of the bottom of the connecting frame and the top of the fixing plate are on the same horizontal plane.

[0013] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0014] 1. In this application, after connecting the fixing plate and the vehicle frame through the fastening rod, lift the outer sleeve. While the outer sleeve slides on the outer surface of the vertical bar, the spring is compressed. Then place the combined plate above the fastening rod and the locking rod, and release the outer sleeve. The bottom of the outer sleeve is snap-connected to the top of the combined plate through a card slot. At this time, the spring pushes the combined plate through the outer sleeve, and the combined plate drives the rubber pad to closely adhere to the tops of the fastening rod and the locking rod. The generated frictional force can effectively limit the loosening of the fastening rod and the locking rod, thereby ensuring the stability of the connection between the power connection socket and the vehicle frame.

[0015] 2. In this application, after the bottom of the outer sleeve is combined with the combined plate, the tab will extend out of the connecting frame and remain inclined at a specified angle under the action of the elastic rotating shaft. After the external interface is connected to the connector, the tab will overlap on the outer surface of the external interface, thereby further improving the stability of the connection between the outer surface interface and the connector. The design of the bent top of the tab can ensure the normal connection between the external interface and the connector. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0024] An electricity connection seat for the frame of an electric two-wheeler includes a fixed plate 1 and a connector 2 that are fixedly matched, and a tightening rod 6 is inserted through the inside of the fixed plate 1. The outer surface of the fixed plate 1 is fixedly connected to a connecting frame 4 through a locking rod 8. The connecting frame 4 has a C-shaped structure. The inner surface of the top of the connecting frame 4 is provided with a vertically telescopic outer sleeve 11. The bottom of the outer sleeve 11 is provided with a pressing component for axially limiting the locking rod 8 and the tightening rod 6.

[0025] After connecting the fixed plate 1 to the frame through the tightening rod 6, lift the outer sleeve 11. While the outer sleeve 11 slides on the outer surface of the vertical bar 10, the spring 12 is compressed. Then, place the composite plate 3 above the tightening rod 6 and the locking rod 8, and release the outer sleeve 11. The bottom of the outer sleeve 11 is clamped to the top of the composite plate 3 through the card slot 7. At this time, the spring 12 pushes the composite plate 3 through the outer sleeve 11, and the composite plate 3 drives the rubber pad 5 to closely adhere to the tops of the tightening rod 6 and the locking rod 8. The generated frictional force can effectively limit the loosening of the tightening rod 6 and the locking rod 8, thereby ensuring the stability of the connection between the electricity connection seat and the frame.

[0026] Specifically, as Figure 2 and Figure 4 shown, an L-shaped bracket is fixedly connected to the outer surface of the outer sleeve 11. The top of the vertical end of the L-shaped bracket is rotatably connected to an overlapping piece 9 that is slidably matched with the top of the connecting frame 4 through an elastic rotating shaft. After the bottom of the outer sleeve 11 is combined with the composite plate 3, the overlapping piece 9 will extend out of the connecting frame 4 and maintain an inclined state at a specified angle under the action of the elastic rotating shaft. After the external interface is connected to the connector 2, the overlapping piece 9 will overlap on the outer surface of the external interface, thereby further improving the stability of the connection between the external interface on the outer surface and the connector 2. The bent design of the top of the overlapping piece 9 can ensure the normal connection between the external interface and the connector 2.

[0027] Specifically, as Figure 2 andFigure 3 As shown, a vertical bar 10 is fixedly connected to the inner surface of the bottom of the connecting frame 4. The outer sleeve 11 is sleeved on the outside of the vertical bar 10, and a spring 12 is fixedly connected between the bottom of the vertical bar 10 and the inner surface of the bottom of the outer sleeve 11. Lift the outer sleeve 11 upwards. While the outer sleeve 11 slides on the outer surface of the vertical bar 10, the spring 12 is compressed. Then place the combined plate 3 above the fastening rod 6 and the locking rod 8. Release the outer sleeve 11. The bottom of the outer sleeve 11 is snap-fitted to the top of the combined plate 3 through the card slot 7. At this time, the spring 12 pushes the combined plate 3 through the outer sleeve 11. The cross-sections of both the vertical bar 10 and the outer sleeve 11 are rectangular structures to limit the axial deflection of the outer sleeve 11. And a lug is fixedly connected to the outer surface of the outer sleeve 11 to facilitate the up and down movement of the outer sleeve 11.

[0028] Specifically, as Figure 1 shown, Figure 2 The pressing-down assembly includes a combined plate 3. A rubber pad 5 is fixedly connected to the bottom of the combined plate 3. The tops of both the locking rod 8 and the fastening rod 6 are abutted against the bottom of the rubber pad 5. The bottom of the outer sleeve 11 is snap-fitted to the top of the combined plate 3 through the card slot 7. The combined plate 3 drives the rubber pad 5 to closely adhere to the tops of the fastening rod 6 and the locking rod 8. The frictional force generated thereby can effectively limit the loosening of the fastening rod 6 and the locking rod 8. The bottom of the connecting frame 4 is snap-fitted to the inner surface of the top of the fixing plate 1 through the engaging groove. And the inner surface of the bottom of the connecting frame 4 and the top of the fixing plate 1 are on the same horizontal plane to ensure that the rubber pad 5 can contact both the locking rod 8 and the fastening rod 6 simultaneously.

[0029] Working principle: After connecting the fixing plate 1 and the vehicle frame through the fastening rod 6, lift the outer sleeve 11 upwards. While the outer sleeve 11 slides on the outer surface of the vertical bar 10, the spring 12 is compressed. Then place the combined plate 3 above the fastening rod 6 and the locking rod 8. Release the outer sleeve 11. The bottom of the outer sleeve 11 is snap-fitted to the top of the combined plate 3 through the card slot 7. At this time, the spring 12 pushes the combined plate 3 through the outer sleeve 11. The combined plate 3 drives the rubber pad 5 to closely adhere to the tops of the fastening rod 6 and the locking rod 8. The frictional force generated thereby can effectively limit the loosening of the fastening rod 6 and the locking rod 8, thus ensuring the stability of the connection between the power connection socket and the vehicle frame. After the bottom of the outer sleeve 11 is combined with the combined plate 3, the tab 9 will extend out of the connecting frame 4 and remain inclined at a specified angle under the action of the elastic rotating shaft. After the external interface is connected to the connector 2, the tab 9 will overlap on the outer surface of the external interface, further improving the stability of the connection between the outer surface interface and the connector 2. The design of the bent top of the tab 9 can ensure the normal connection between the external interface and the connector 2.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to the embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
