[0031] like Figure 2 As shown, one aspect of this application provides a front storage box 100 for an electric vehicle, including a connector 20, a front panel 10 and a housing 30 that are fastened together to form an inner cavity. The housing 30 has a through hole 32 for passing through a head tube and a notch 34 communicating with the through hole. The connector 20 has a filling part 23 to fill the notch 34. The housing 30 is connected to the connector 20 by a fastener. A groove 25 is provided on the connector 20. A connecting block 31 is provided on the housing 30. The connector 20 and the housing 30 are positioned by insertion into the connecting block 31 via the groove 25.

[0032] For details, please refer to Figure 1 and Figure 3 The diagram illustrates a front storage box 100 for an electric vehicle. During the installation of an electric vehicle, the frame needs to be assembled, and then parts of the frame are covered using various covers. When focusing on the head tube of the frame, a front storage box is also needed to cover at least a portion of the head tube. For ease of installation, the front storage box consists of two interlocking shell-shaped structures: a front panel 10 and a housing 30. During installation, the front panel 10 and housing 30 cover portions of the head tube from both sides using an interlocking mechanism. For example, the front panel 10 covers the head tube from the side closer to the front of the vehicle, while the housing covers the head tube from the side closer to the rear. To facilitate the connection between the head tube and the handlebars, a through hole 32 is often provided in the housing 30 so that the top of the head tube can pass through smoothly. For ease of installation, a notch 34 communicating with the through hole 32 is provided in the housing, allowing the housing to approach the head tube from the side closer to the rear, so that the head tube enters the through hole 32 through the notch 34.

[0033] Although adding the notch 34 makes installation easier, it can also cause debris or rainwater to enter the cabinet through the notch 34, damaging the wiring harness and control devices inside the cabinet. Therefore, to prevent this problem, the notch 34 can be filled by the filling part 23 on the connector 20 to maintain the integrity of the entire front storage box.

[0034] When connecting the connector to the front storage compartment, the stability and reliability of the connection can be increased through fasteners and positioning structures. Specifically, for example... Figure 1As shown, the electric vehicle front storage box 100 provided in this application includes a front panel 10, a connector 20, and a housing 30. The front panel 10 and the housing 30 can be configured to form an inner cavity 40. Figure 1 The image shows one side of the front bulkhead 10 having an inner cavity 40 after it is fastened to the housing 30, and an external space 50 opposite to the inner cavity 40. It should be understood that... Figure 1 Only a portion of the front bulkhead and the housing are shown, that is, the inner cavity 40 provides space for housing the head tube and wiring harness.

[0035] To facilitate the fixing of the connector 20, the housing 30 is fixedly connected to the connector 20 via a fastener. To further maintain a stable fixing relationship, a positioning structure can also be used to fix the housing 30 and the connector 20. For details, refer to... Figure 2 The positioning structure includes a groove 25 on the connector 20 and a connecting block 31 on the housing 30. The groove 25 and the connecting block 31 are interlocked, thereby limiting the groove 25 and the connecting block 31 to each other, increasing the stability and reliability of the connection between the connector 20 and the housing 30.

[0036] In some embodiments, the specific shape of the groove 25 can be rectangular, triangular, or circular, and the specific shape is not limited.

[0037] In some embodiments, the shape of the connecting block 31 is the same as the shape of the groove 25.

[0038] Optionally, a first flange 24 is provided on the connector 20 to pass through the through hole 32, and the side wall of the first flange 24 is limited and abutted against the inner wall of the through hole 32. A second flange 33 is provided along a portion of the periphery of the through hole 32. The first flange 24 and the second flange 33 are spliced ​​together to enclose the through hole 32.

[0039] Specifically, such as Figure 5 and Figure 6 As shown, the connector 20 is provided with a first flange 24. The sidewall of the first flange 24 fits against the inner wall of the through hole 32 to form a limiting contact, increasing the stability of the connector 20 and the housing 30 after connection. A second flange 33 is provided on a portion of the periphery of the through hole 32. The first flange 24 and the second flange 33 are spliced ​​to form a rim around the periphery of the through hole, surrounding the head tube. In some possible embodiments, the first flange 24 and the second flange 33 can be spliced ​​to form a flange of circular, square, or other shapes. For example... Figure 5 and Figure 6 In the middle, the first flange 24 and the second flange 33 are both round flanges, so that when the head tube or wire harness passes through the inside of the front storage box 100, it will not be scratched by the edge of the through hole 32.

[0040] In some implementations, the first flange 24 and the second flange 33 may each have a rounded corner of any angle, as long as the first flange 24 and the second flange 33 are joined together to enclose the through hole.

[0041] Optionally, the groove 25 and the connecting block 31 are both located at the joint between the first flange 24 and the second flange 33.

[0042] Specifically, as mentioned above, the groove 25 is located at the joint of the first flange 24, and the connecting block 31 is located at the joint of the second flange 33. Figure 2 As shown, when the connector 20 is connected to the housing 30, the groove 25 is inserted and positioned with the connecting block 31. At this time, the insertion point of the groove 25 and the connecting block 31 is also the splicing point 60 of the first flange 24 and the second flange 33. This ensures that the first flange 24 and the second flange 33 will not be misaligned during splicing, the transition at the splicing point is smooth, and the entire flange remains stable after splicing, effectively protecting the head tube and wire harness passing through the through hole 32.

[0043] Optionally, the filling portion 23 is adjacent to the first flange 24.

[0044] Specifically, such as Figure 5 As shown, the filling portion 23 on the connector 20 is adjacent to the first flange 24. This allows the filling portion 23 to extend to the boundary where the notch 34 communicates with the through hole 32 when filling the notch 34, thus fully filling the notch 34. Figure 6 As shown, the notch 34 on the housing 30 connects to the through hole 32. When the side wall of the first flange 24 abuts against the inner wall of the through hole 32, the filling part 23 can fill the notch 34. The filling part 23, the first flange 24, and the groove 25 are connected in sequence to ensure that the connector 20 and the housing 30 are positioned by insertion through the groove 25 and the connecting block 31. The first flange 24 and the second flange 33 are spliced ​​to surround the through hole 32, while the filling part 23 fills the notch 34.

[0045] Optionally, the connector 20 is provided with guide grooves 22 located on opposite sides of the filling part 23, and the housing 30 is provided with a third flange 35. The connector 20 and the housing 30 are positioned by insertion of the guide grooves 22 and the third flange 35.

[0046] Specifically, such as Figure 5 As shown, guide grooves 22 are provided on opposite sides of the filling portion 23, and the guide grooves 22 extend along the direction in which the connector 20 connects to the housing 30. Figure 6 As shown, a third flange 35 is provided on the housing 30, and the third flange 35 extends along both sides of the notch 34. The guide groove 22 can restrict the movement of the third flange 35 in the direction perpendicular to the extension direction of the guide groove 22, ensuring the stability of the connection between the connector 20 and the housing 30.

[0047] In some embodiments, the third flange 35 is a rectangular flange. The rectangular flange can increase the contact area with the guide groove 22, reduce the gap when the connector 20 is connected to the housing 30, and ensure the tightness of the filling part 23 and the notch 34.

[0048] Optionally, the connector 20 may also include an extension 21 connected to opposite sides of the filling portion 23, the extension 21 abutting against the housing on both sides of the notch 34.

[0049] Specifically, such as Figure 5 As shown, the extension 21 is located on opposite sides of the guide groove 22. When the connector 20 is connected to the housing 30, the filling part 23 fills the gap 34. The extension 21 abuts against the housing on both sides of the gap 34, so that the gap 34 can be completely filled by the filling part 23, reducing the gap between the connector 20 and the housing 30 and ensuring the stability of the front storage box 100.

[0050] Optionally, the filling portion 23 is flush with the outer surface of the housing 30 at the notch 34.

[0051] Specifically, such as Figure 5 As shown, the filling part 23 is flush with the outer surface of the housing 30 at the notch 34, so that the entire filling part 23 fills the notch 34, ensuring the sealing of the front storage box 100.

[0052] Optionally, a positioning groove 27 is provided at the end of the filling part 23 near the front bulkhead 10, and a positioning post 11 is provided on the front bulkhead 10 to be inserted into the positioning groove 27.

[0053] Specifically, such as Figure 5 As shown, a positioning groove 27 for connection with the front bulkhead is provided on the side of the filling part 23 away from the first flap 24. Figure 4 As shown, a positioning post 11 is provided on the front panel to be inserted into the positioning groove 27. The connector 20 is inserted into the connecting block 31 on the housing 30 through the groove 25 for positioning, and the connector 20 and the housing 30 are further fixed by the fastener. The connector 20 is inserted into the positioning post 11 on the front panel 10 through the positioning groove 27 for positioning, which ensures the stability between the front panel 10, the connector 20 and the housing 30, and thus ensures the stability of the entire front storage box 100.

[0054] In some embodiments, the shape of the positioning groove 27 can be square, triangular or circular, as long as the positioning post 11 has the same shape as the positioning groove 27, the specific shape is not limited.

[0055] Optionally, the front bulkhead 10 is connected to the housing 30 by fasteners, and the outer surfaces of the front bulkhead 10 and the housing 30 are flush at the fastening point.

[0056] Specifically, such as Figure 1 As shown, fasteners connect the front panel 10 and the housing 30, ensuring the stability of the entire front storage box 100 formed by the front panel 10 and the housing 30. The outer surfaces of the front panel 10 and the housing 30 are flush at the fastening point, ensuring the airtightness of the front storage box 100.

[0057] The aforementioned fasteners and fixtures can be screws, pins, or other components that can be used for connection, without specific limitations.

[0058] In some embodiments, a reinforcing rib 26 is provided on the outside of the groove 25. The reinforcing rib 26 can enhance the structural strength of the groove 25. The number of reinforcing ribs can be one, two or more, and the specific number is not limited.

[0059] In some embodiments, the connecting block 31 is provided with a guide slope, which makes it convenient for the groove 25 to be inserted and positioned with the connecting block 31.

[0060] Furthermore, during installation, the connector 20 moves along the notch 34 toward the through hole 32. Simultaneously, the third flange 35 enters the extension direction of the guide groove 22 until the connector block 31 on the housing 30 is inserted into the groove 25 of the connector 20 and cannot move in this direction. At this time, the connector 20 is lifted from the inner cavity 40 of the front storage box 100 toward the outer space 50. The first flange 24 and the second flange 33 are joined to enclose the through hole 32. The filling part 23 and the extension part 21 fill the notch 34. Then, the connector is connected to the housing 30 through the slot 28 on the extension part 21 by the fastener. The positioning post 11 on the front panel 10 is connected through the positioning groove 27. Finally, the front panel 10 and the housing 30 are connected by fasteners so that the front panel 10 and the housing 30 are flush at the fastening point. This achieves a tight connection between the front panel 10, the connector 20, and the housing 30, reduces the gap between the front panel 10, the connector 20, and the housing 30, prevents misalignment between the front panel 10, the connector 20, and the housing 30, and improves the stability of the front storage box 100.

[0061] In another aspect of this application, an electric vehicle is provided, including a frame and a front storage box 100 of any of the above-described types, the front storage box 100 being disposed on the frame.

[0062] The aforementioned front storage box 100 is installed on the electric vehicle to improve its stability. The front storage box 100 is detachable and can be replaced with a front storage box of the appropriate size according to the actual size. The filling part 23 of the connector 20 on the front storage box fills the gap 34 caused by the head tube, making the front storage box 100 more sealed and improving the sealing and stability of the electric vehicle.

[0063] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
