[0027] like Figure 1 and Figure 2 As shown, the present application provides an electric two-wheeled vehicle 100, which may be an electric motorcycle or an electric bicycle, and the present application does not limit this.

[0028] In order to clearly illustrate the technical solution of this application, the following is also defined: Figure 1 In this application, the length direction of the electric two-wheeled vehicle 100 refers to the front, rear, left, right, up and down. Figure 1 The front-to-back direction in the electric two-wheeled vehicle 100 is the width direction. Figure 1 The left and right directions in the figure are the height directions of the electric two-wheeled vehicle 100. Figure 1 The up and down directions in .

[0029] Among them, the electric two-wheeled vehicle 100 includes a frame 11, a running system 12, a suspension assembly 13, a power assembly 14 and a power battery 15. The frame 11 serves as the basic framework of the electric two-wheeled vehicle 100 and is used to support the running system 12, the suspension assembly 13, the power assembly 14 and the power battery 15. The running system 12 is at least partially located below the frame 11 and is connected to the frame 11 through the suspension assembly 13, that is, the suspension assembly 13 is used to connect the running system 12 to the frame 11. The power assembly 14 is supported by the frame 11 and is transmission-connected to the running system 12, so that the running system 12 can be driven to move by the power assembly 14. The power battery 15 is supported by the frame 11 and is electrically connected to the power assembly 14, so that the power battery 15 can supply energy to the power assembly 14.

[0030] It should be noted that the powertrain 14 of the present application includes a drive motor, which is electrically connected to a power battery 15 , so that the power battery 15 can supply power to the drive motor.

[0031] As an implementation method, the running system 12 includes a front wheel 121 and a rear wheel 122, and the front wheel 121 and the rear wheel 122 are both connected to the frame 11 through a suspension assembly 13. The frame 11 includes a middle frame 111 located between the front wheel 121 and the rear wheel 122. The middle frame 111 is surrounded by a storage space, and the power battery 15 is located in the storage space and supported by the middle frame 111. The electric two-wheeled vehicle 100 also includes a battery pressure plate assembly 16, which is connected to the frame 11 and at least partially covers the storage space formed around the middle frame 111. The battery pressure plate assembly 16 is used to press the power battery 15 so that the power battery 15 can be fixed in the storage space, thereby providing working stability of the power battery 15 during the driving of the electric two-wheeled vehicle 100.

[0032] like Figure 2 and Figure 3As shown, specifically, the battery pressure plate assembly 16 includes a press member 161, which extends substantially along a predetermined plane 1601 and substantially along the width direction of the electric two-wheeled vehicle 100. The press member 161 at least partially protrudes away from the predetermined plane 1601 to form a protrusion 162. The press member 161 at least partially protrudes upward to form the protrusion 162. The protrusion 162 can be considered to be formed by stretching the press member 161, that is, the thickness of the protrusion 162 is substantially the same as the thickness of the press member 161.

[0033] More specifically, when the battery pressure plate assembly 16 is connected to the frame 11, the protrusion 162 is at least partially located above the pressing part 161, and there is a preset distance between at least part of the protrusion 162 and the preset plane 1601 along the height direction, so that the height of the protrusion 162 along the height direction of the electric two-wheeled vehicle 100 is higher than the height of the pressing part 161 along the height direction of the electric two-wheeled vehicle 100.

[0034] like Figure 2 、 Figure 3 and Figure 4 As shown, in this embodiment, the power battery 15 is selected from one of a first battery 151 and a second battery 152. The height of the first battery 151 along the height direction of the electric two-wheeled vehicle 100 is greater than the height of the second battery 152 along the height direction of the electric two-wheeled vehicle 100. As an optional implementation, in this application, the first battery 151 is a lead-acid battery and the second battery 152 is a lithium battery.

[0035] When the power battery 15 is the first battery 151 (refer to Figure 2 ), the press fitting 161 is connected to the frame 11 and abuts against the first battery 151. When the power battery 15 is the second battery 152 (refer to Figure 4), the protruding member 162 is connected to the vehicle frame 11, and the pressing member 161 abuts against the second battery 152. Through the above arrangement, when the power battery 15 is the first battery 151, the height of the pressing member 161 can be made to be the first height, and when the power battery 15 is the second battery 152, the height of the pressing member 161 can be made to be the second height, and the first height is greater than the second height, so that the pressing member 161 can adapt to the first battery 151 and the second battery 152 of different heights, thereby improving the versatility of the battery pressing plate assembly 16 and reducing the production cost of the battery pressing plate assembly 16, thereby further reducing the production cost of the electric two-wheeled vehicle 100. As an implementation method, the protruding member 162 includes a mounting portion 1621 substantially parallel to the preset plane 1601. When the power battery 15 is the second battery 152, the mounting portion 1621 is connected to the vehicle frame 11. Among them, since the upper surface of the power battery 15 is basically flat, when the mounting portion 1621 is connected to the vehicle frame 11, the above arrangement can make the pressing part 161 basically parallel to the upper surface of the power battery 15, thereby facilitating improving the pressing stability of the pressing part 161 and the power battery 15.

[0036] Specifically, the protruding member 162 includes a connecting portion 1622 located between the mounting portion 1621 and the pressing member 161, and the mounting portion 1621 and the pressing member 161 are connected by the connecting portion 1622. The connecting portion 1622 is used to form a preset spacing between the mounting portion 1621 and the pressing member 161 along the height direction of the electric two-wheeled vehicle 100, so that there is a height difference between the mounting portion 1621 and the pressing member 161, thereby enabling the battery pressure plate assembly 16 to adapt to power batteries 15 of different sizes (heights), thereby improving the versatility of the battery pressure plate assembly 16.

[0037] It should be noted that in the present application, the pressing member 161, the connecting portion 1622, and the mounting portion 1621 are integrally formed, and the connecting portion 1622 and the mounting portion 1621 can be considered to be formed by stretching the pressing member 161. Therefore, the thickness of the connecting portion 1622, the mounting portion 1621, and the pressing member 161 are substantially the same. From the extension direction of the battery pressure plate assembly 16, that is, from the width direction of the electric two-wheeled vehicle 100, the pressing member 161, the mounting portion 1621, and at least a portion of the connecting portion 1622 are substantially arranged in a "Z" shape, so that the connecting portion 1622 and the mounting portion 1621 can be surrounded by an avoidance space 1623. Therefore, during the connection process of the mounting portion 1621 to the frame 11, the avoidance space 1623 allows the pressing member 161 to move synchronously with the mounting portion 1621 until the pressing member 161 abuts the power battery 15.

[0038] In this embodiment, a pressure plate mounting point 112 is provided on the vehicle frame 11. When the power battery 15 is the first battery 151, the pressing member 161 is connected to the pressure plate mounting point 112. When the power battery 15 is the second battery 152, the protruding member 162 is connected to the pressure plate mounting point 112. Through this arrangement, the protruding member 162 or the pressing member 161 can be connected to the same pressure plate mounting point 112, that is, the protruding member 162 or the pressing member 161 can share the same mounting point, thereby reducing the number of additional mounting points on the vehicle frame 11, thereby simplifying the structure of the vehicle frame 11, and facilitating improved structural compactness of the vehicle frame 11.

[0039] As an optional implementation method, there are two protrusions 162 and two pressure plate mounting points 112. The two protrusions 162 are respectively located at the two ends of the pressing part 161 along the width direction of the electric two-wheeled vehicle 100. When the power battery 15 is the second battery 152, each protrusion 162 is connected to a pressure plate mounting point 112, which is beneficial to improve the connection stability between the battery pressure plate assembly 16 and the frame 11.

[0040] As an optional implementation method, two pressure plate mounting points 112 are provided. When the power battery 15 is the first battery 151, the pressing part 161 is connected to a pressure plate mounting point 112 at both ends along the width direction of the electric two-wheeled vehicle 100, thereby facilitating improving the connection stability between the battery pressure plate assembly 16 and the frame 11.

[0041] like Figure 3 、 Figure 5 and Figure 6 As shown, specifically, the pressure plate assembly 16 also includes a fastener 163. The pressing member 161 defines a first mounting hole 1611, and the protruding member 162 defines a second mounting hole 1624. When the power battery 15 is the first battery 151, the fastener 163 is inserted through the first mounting hole 1611 and connected to the vehicle frame 11. When the power battery 15 is the second battery 152, the fastener 163 is inserted through the second mounting hole 1624 and connected to the vehicle frame 11. The fastener 163 may be a bolt, and the pressure plate mounting point 112 on the vehicle frame 11 may have a threaded hole or a nut fixed thereto, allowing the fastener 163 to be directly fixed to the pressure plate mounting point 112, thereby improving the connection stability between the battery pressure plate assembly 16 and the vehicle frame 11. More specifically, the second mounting hole 1624 is defined on the mounting portion 1621.

[0042] It should be noted that, in the present application, the connection between the battery pressure plate assembly 16 and the vehicle frame 11 refers to the connection between the battery pressure plate assembly 16 and the middle vehicle frame 111 .

[0043] As an implementation, the electric two-wheeled vehicle 100 further includes a buffer assembly 17. The buffer assembly 17 is used to buffer or reduce shock on the components of the electric two-wheeled vehicle 100 so as to prevent rigid collisions between the components of the electric two-wheeled vehicle 100, thereby increasing the service life of the components of the electric two-wheeled vehicle 100.

[0044] Among them, the buffer assembly 17 includes a buffer pad 171 with a buffering function. The buffer pad 171 is located between the power battery 15 and the pressing part 161, so that the buffer pad 171 can provide buffering for the power battery 15 and the battery pressure plate assembly 16 to avoid rigid collision between the power battery 15 and the battery pressure plate assembly 16, thereby improving the service life of the power battery 15 and the battery pressure plate assembly 16, and improving the safety of the power battery 15.

[0045] Specifically, the cushion pad 171 can be configured as a rubber block, which facilitates direct bonding of the cushion pad 171 to the power battery 15 and / or the battery platen assembly 16, thereby improving the installation convenience of the cushion pad 171. It is understood that the cushion pad 171 can also be configured as other elastically deformable materials such as rubber, as long as the cushion pad 171 can provide a cushioning effect.

[0046] like Figure 3 and Figure 5 As shown, as an optional implementation, the electric two-wheeled vehicle 100 further includes a body covering 18 (refer to Figure 1 ), the body cover 18 is connected to the frame 11, and the body cover 18 is used to protect the internal components of the electric two-wheeled vehicle 100.

[0047] When the power battery 15 is the first battery 151, the vehicle body cover 18 includes a first footrest 181 for supporting the driver's foot. The first footrest 181 is connected to the vehicle frame 11. The first footrest 181 is provided with a first support column 1811, which is located below the first footrest 181 and abuts against the press-fit component 161. The length of the first support column 1811 along the height direction of the electric two-wheeled vehicle 100 can be adjusted as needed. In other words, the length of the first support column 1811 along the height direction of the electric two-wheeled vehicle 100 can be any length, and this application does not impose any restrictions. The only requirement is that the first support column 1811 can support the first footrest 181.

[0048] Specifically, the first support column 1811 can be integrally formed with the first footrest 181, eliminating the need to mount the first support column 1811 on the first footrest 181, thereby improving assembly convenience of the first support column 1811. Alternatively, the first support column 1811 can be an elastic column that snaps into contact with the first footrest 181, thereby facilitating improved cushioning between the first support column 1811 and the battery pressure plate assembly 16.

[0049] like Figure 3 and Figure 6 As shown, as an optional implementation, when the power battery 15 is the second battery 152, the vehicle body cover 18 includes a second foot pedal 182 for supporting the driver's feet, and the second foot pedal 182 is connected to the vehicle frame 11. The second foot pedal 182 is provided with a second support column 1821, and the second support column 1821 is located below the second foot pedal 182 and abuts against the press-fitting part 161. The length of the second support column 1821 along the height direction of the electric two-wheeled vehicle 100 is greater than the height of the protruding part 162 along the height direction of the electric two-wheeled vehicle 100. Through the above arrangement, the gap between the battery pressure plate assembly 16 and the press-fitting part 161 can be increased by the second support column 1821 to avoid the protruding part 162 interfering with the installation of the second foot pedal 182 when fixing the second battery 152.

[0050] It should be noted that the structure and installation method of the second support column 1821 are basically the same as the structure and installation method of the first support column 1811, and will not be repeated here.

[0051] It should be noted that the connection between the first foot pedal 181 and the frame 11 is the connection between the first foot pedal 181 and the middle frame 111 , and the connection between the second foot pedal 182 and the frame 11 is the connection between the second foot pedal 182 and the middle frame 111 .

[0052] As another optional implementation, the battery platen assembly 16 can be a substantially plate-shaped structure, that is, the battery platen assembly 16 only includes a press-fitting part 161. In this case, the vehicle frame 11 is provided with multiple platen mounting points 112 at different heights, and the battery platen assembly 16 can be connected to the platen mounting points 112 at different heights, thereby making the height of the battery platen assembly 16 relative to the vehicle frame 11 adjustable, so that the battery plate can adapt to power batteries 15 of different sizes (heights).

[0053] Specifically, the pressure plate mounting points 112 include a first mounting point and a second mounting point, and the height of the first mounting point along the height direction of the electric two-wheeled vehicle 100 is higher than the height of the second mounting point along the height direction of the electric two-wheeled vehicle 100 .

[0054] When the power battery 15 is the first battery 151 , the pressing part 161 of the battery pressure plate assembly 16 is connected to the first mounting point; when the power battery 15 is the second battery 152 , the pressing part 161 of the battery pressure plate assembly 16 is connected to the second mounting point.

[0055] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims appended to this application.
