Technical Field

[0001] The present invention relates to a vehicle, and more particularly to an electric two-wheeled vehicle. Background Art

[0002] With the strong dominance of new energy forces in the market, various types of two-wheeled vehicles are gradually electrified. In addition to electric bicycles for daily commuting, electric motorcycles and electric scooters with recreational attributes are also gradually electrified. Unlike electric bicycles, electric motorcycles and electric scooters have higher requirements for the battery life, fixation and structural strength of battery components. How to disassemble and replace the battery more quickly, and how to ensure the installation strength of the battery on the electric two-wheeled vehicle while meeting the above requirements are issues that need to be urgently addressed in the research and development of electric two-wheeled vehicles. Summary of the invention

[0003] In order to solve the deficiencies of the prior art, an object of the present invention is to provide an electric two-wheeled vehicle in which a battery assembly is easy to disassemble and a frame and a battery assembly are firmly connected.

[0004] In order to achieve the above object, the present invention adopts the following technical solution:

[0005] An electric two-wheeled vehicle comprises a frame, the frame comprising a main frame and a supporting frame arranged below the main frame, the main frame and the supporting frame being fixedly connected; a body covering, the body covering being at least partially arranged on the frame; a running assembly, the running assembly being at least partially arranged below the frame; a motor assembly, the motor assembly being used to drive the running assembly; a battery assembly, the battery assembly being used to provide energy for the motor assembly; a accommodating space being formed between the main frame and the supporting frame, the battery assembly being at least partially arranged in the accommodating space; the battery assembly comprising a battery compartment and a power battery, when the power battery is in an assembled state, the power battery is at least partially arranged in the battery compartment, an assembling assembly is also arranged between the battery compartment and the supporting frame, the battery compartment can rotate relative to the supporting frame through the assembling assembly, and the battery compartment can drive the power battery to rotate relative to the supporting frame.

[0006] Further, a longitudinal plane perpendicular to the width direction of the electric two-wheeled vehicle and passing through the width center of the electric two-wheeled vehicle is defined, and the rotation axis of the assembly component basically extends along the length direction of the electric two-wheeled vehicle and is located on the longitudinal plane.

[0007] Furthermore, the battery compartment includes a storage state and an open state relative to the frame. When the battery compartment is in the storage state, the battery compartment is basically located in the accommodating space. When the battery compartment is in the open state, the battery compartment is at least partially located outside the accommodating space. When the battery compartment is in the open state, the power battery can be directly taken out of the battery compartment.

[0008] Furthermore, the assembly component includes a support plate fixedly connected to the battery compartment and a connecting plate fixedly connected to the supporting frame, the connecting plate can rotate relative to the support plate, and an elastic member is provided between the connecting plate and the support plate.

[0009] Furthermore, the main frame includes a vertical bracket extending substantially along the height direction, and the main frame also includes a fixed bracket arranged between the vertical frame and the battery assembly, and the battery assembly is connected to the vertical bracket via the fixed bracket.

[0010] Furthermore, a positioning assembly is provided between the fixed bracket and the battery assembly, and the positioning assembly includes a guide rail fixedly connected to the battery compartment and a positioning member connected to the fixed bracket, and the positioning member is at least distributed in the guide rail and can move relative to the guide rail.

[0011] Furthermore, the electric two-wheeled vehicle also includes a locking device, which includes an actuator component at least partially arranged between the battery compartment and the frame, and the locking component can limit the rotation of the battery compartment through the actuator component.

[0012] Furthermore, the frame also includes an elastic support member, and the main frame includes a longitudinal bracket extending along the length direction. When the power battery is in an assembled state and the battery compartment is in a stored state, the elastic support member is at least partially arranged between the battery assembly and the longitudinal bracket, and the elastic support member can provide a pre-tightening force in the height direction between the battery assembly and the longitudinal bracket.

[0013] Furthermore, the frame also includes a side support for providing support when the electric two-wheeled vehicle is stationary, and the side support is arranged on one side of the electric two-wheeled vehicle; when the battery compartment is in an open state, the battery compartment faces a side away from the side support.

When viewed along the width direction of the electric two-wheeled vehicle, the side guard plates at least partially overlap with the battery assembly, and the side guard plates arranged on the side away from the side support can be flipped synchronously with the battery compartment.

[0015] By setting the battery compartment and the frame as a rotating connection and using a lock to control the relative state of the battery compartment and the frame, the battery can be firmly connected to the frame during operation, and the battery can be quickly disassembled, assembled or replaced when replacement and maintenance are required. Under this premise, the stability and strength of the connection between the battery assembly and the frame can be guaranteed, avoiding the quick disassembly structure setting from weakening the battery connection strength.

[0025] In order to clearly illustrate the technical solutions of the embodiments of the present invention or the prior art, the drawings required for use in the embodiments or the prior art descriptions are briefly introduced below. Obviously, the content described below is only one embodiment of the present invention. For ordinary technicians in this field, all other embodiments obtained without creative work are within the protection scope of the present invention.

[0026] like Figure 1 As shown, the present application provides an electric two-wheeled vehicle 100, which includes a frame 11, a body cover 12, a running assembly 13, and a battery assembly 14 (see Figure 2) and motor assembly 15. The frame 11 constitutes the basic framework of the electric two-wheeled vehicle 100, and the battery assembly 14 and the motor assembly 15 are both arranged on the frame 11 and supported by the frame 11, the travel assembly 13 is at least partially arranged under the frame 11 and is arranged to be rotatably connected with the frame 11, and the body cover 12 at least partially covers the motor assembly 15 and the battery assembly 14, providing protection for the battery assembly 14 and the motor assembly 15 to a certain extent. For the convenience of description, in this application, the front and rear direction of the driver of the electric two-wheeled vehicle 100 during normal driving is defined as the length direction of the electric two-wheeled vehicle 100, the left and right direction of the driver is defined as the width direction of the electric two-wheeled vehicle 100, and the up and down direction is defined as the height direction of the electric two-wheeled vehicle 100.

[0027] like Figure 2 As shown, the frame 11 includes a main frame 111 for supporting the whole vehicle structure and a support frame 112 arranged below the main frame 111. The support frame 112 is fixedly connected to the main frame 111 and a receiving space S1 is formed between the support frame 112 and the main frame 111. The battery assembly 14 and the motor assembly 15 are basically arranged in the receiving space S1. The main frame 111 and the support frame 112 together constitute the support and protection for the motor assembly 15 and the battery assembly 14. Further, the main frame 111 also includes a longitudinal support 1111 extending along the basic length direction and a vertical support 1112 extending along the basic height direction. Correspondingly, the support frame 112 also includes a longitudinal support frame 1121 extending along the basic length direction and a vertical support frame 1122 extending along the basic height direction. As an optional implementation, the motor assembly 15 is arranged in the accommodation space S1 and close to the vertical bracket 1112 and the longitudinal support frame 1121, and the motor assembly 15 is fixedly connected to the longitudinal support frame 1121 and / or the vertical bracket 1112, that is, the battery assembly 14 is arranged in the accommodation space S1 near the rearmost and lowermost part, and the battery assembly 14 is arranged in front of the motor assembly 15. This arrangement can fully and effectively utilize the irregular space between the vertical bracket 1112 and the longitudinal support frame 1121, and fully utilize the shape characteristics of the motor assembly 15 itself to place the motor assembly 15 therein, which can effectively enhance the compactness of the spatial layout and form or leave a relatively regular area in the accommodation space S1 for accommodating the battery assembly 14.

[0028] like Figure 3 and Figure 4As shown, the battery assembly 14 includes a power battery 141 and a battery compartment 142 for accommodating and protecting the power battery 141, and the battery compartment 142 is configured as a cavity that is substantially consistent with the shape of the power battery 141. As an optional embodiment, the power battery 141 in the present application is substantially configured as a rectangular structure, and therefore, the battery compartment 142 in the present application is substantially configured as a rectangular cavity structure for accommodating the power battery 141. The battery compartment 142 is substantially located in the accommodating space S1 in front of the motor assembly 15 and is at least partially fixedly connected to the longitudinal support frame 1121, and the longitudinal support frame 1121 provides support for the battery compartment 142 and the power battery 141. The frame 11 also includes an assembly component 113, and the battery compartment 142 is configured to be rotatably connected to the longitudinal support frame 1121 through the assembly component 113. Specifically, the longitudinal support frame 1121 includes two support frames distributed along the width direction, and the assembly components 113 are fixedly connected to the longitudinal support frames 1121 distributed along the width direction, respectively, to ensure the stability of the fixed connection between the battery compartment 142 and the frame 11.

[0029] like Figure 3 As shown, the assembly component 113 includes a support plate 1131 fixedly connected to the longitudinal support frame 1121, a connecting plate 1132 fixedly connected to the battery compartment 142, and an elastic member 1133 disposed between the support plate 1131 and the connecting plate 1132. The connecting plate 1132 and the support plate 1131 are configured to be rotatably connected, and the configuration of the elastic member 1133 enables a pre-tightening force toward one side to be formed between the connecting plate 1132 and the support plate 1131, that is, when no pressure is applied to the connecting plate 1132, the connecting plate 1132 can rotate relative to the support plate 1131 under the action of the pre-tightening force of the elastic member 1133, thereby driving the battery compartment 142 to rotate. This arrangement enables the battery compartment 142 to rotate relative to the longitudinal support frame 1121, that is, the opening of the battery compartment 142 can be rotated to an area without interference from other components, which facilitates the assembly and replacement of the power battery 141. After the assembly is completed, the battery compartment 142 can also be flipped to the original connection position with the frame 11 to ensure the fixed connection between the power battery 141 and the longitudinal support frame 1121. That is, the battery compartment 142 includes a storage state and an open state relative to the frame 11. Specifically, the storage state of the battery compartment 142 refers to a state in which the battery compartment 142 does not flip relative to the frame 11. When the vehicle is in operation, the battery compartment 142 must be in the storage state. The open state of the battery compartment 142 refers to a state in which the battery compartment 142 is flipped to a state in which the power battery 141 can be taken out from the inside of the battery compartment 142 without any obstacles.

[0030] like Figure 3 and Figure 4As shown, as an optional embodiment, the assembly component 113 is at least partially arranged between the longitudinal support frames 1121 distributed along the width direction, and by setting the position of the assembly component 113 accordingly, the rotation axis L1 between the connecting plate 1132 and the support plate 1131 basically extends along the length direction of the electric two-wheeled vehicle 100 and is basically parallel to the horizontal plane. This arrangement can ensure that the battery compartment 142 can only be reversed relative to the left or right side of the electric two-wheeled vehicle 100. It can be understood that for a two-wheeled vehicle, the left or right side has a larger placement space on the whole vehicle, which can accommodate the flipping space occupied by the battery compartment 142. Further, a longitudinal plane P1 perpendicular to the width direction of the electric two-wheeled vehicle 100 and passing through the width center of the electric two-wheeled vehicle 100 is defined. As an optional embodiment, the rotation axis L1 of the assembly component 113 is basically arranged on the longitudinal plane P1. This arrangement can minimize the angle required to rotate the battery compartment 142 to remove the power battery 141 under the premise that the width and height of the battery compartment 142 are certain, that is, this arrangement can effectively reduce the amount of rotation of the battery compartment 142 from the storage state to the open state. Since the large mass of the power battery 141 itself can easily cause the center of gravity of the entire vehicle to shift after the battery compartment 142 is reversed when the battery compartment 142 is in the open state, if the center of gravity shift cannot be effectively controlled, it is easy to cause the vehicle itself to be unstable during the removal of the power battery 141, causing the vehicle to tip over and reducing the user experience. Furthermore, the maximum movement range of the side flip is much larger than the space occupied by the middle deflection. This arrangement can effectively save the space occupied by the battery assembly 14 in the height direction of the electric two-wheeled vehicle 100, and achieve compactness in the spatial layout.

[0031] It can be understood that in other embodiments, the most suitable disassembly position is selected according to the overall layout of the vehicle, and the position of the rotation axis L1 of the assembly component 113 can also be set to extend along other directions, or the rotation axis L1 of the assembly component 113 can also be set to form a certain angle with the horizontal plane, so that the opening of the battery compartment 142 is oriented to the most suitable position when opened.

[0032] like Figures 3 to 5 As shown, in order to make the connection between the battery compartment 142 and the frame 11 more stable, a fixed bracket 1113 is arranged between the battery compartment 142 and the battery vertical bracket 1112, and a locking device 16 is also arranged between the battery compartment 142 and the vertical support frame 1122. Through this arrangement, the battery compartment 142 is hard-connected with the frame 11 in the length direction, so that the electric two-wheeled vehicle 100 can avoid the force generated by acceleration in the starting stage or the inertia force during braking, which causes the battery assembly 14 to be violently displaced in the front and rear directions, resulting in a decrease in the connection strength between the battery assembly 14 and the frame 11, affecting the performance of the entire vehicle and even threatening driving safety.

[0033] Optionally, the fixed bracket 1113 and the vertical bracket 1112 are configured to be fixedly connected or integrally formed, and the fixed bracket 1113 extends substantially along the length direction of the electric two-wheeled vehicle 100. A positioning assembly 114 is also provided between the fixed bracket 1113 and the battery compartment 142, and the positioning assembly 114 includes a guide rail 1141 and a positioning member 1142, and the positioning member 1142 can be relatively displaced in the guide rail 1141 by friction or rolling, so that the two relative components can be fixedly connected while also allowing the two components to have a phase position shift. In the present application, the guide rail 1141 is fixedly connected to the battery compartment 142, and the positioning member 1142 is fixedly connected to the fixed bracket 1113, and the guide rail 1141 is configured as a section of an arc-shaped track, and the positioning member 1142 is at least partially located in the arc-shaped track and can move relative to the arc-shaped guide rail 1141. It can be understood that the center of the arc guide rail 1141 is basically located on the rotation axis L1 of the assembly component 113, that is, the relative motion trajectory between the guide rail 1141 and the positioning is the relative motion trajectory between the battery compartment 142 and the fixed bracket 1113 during the rotation process. This arrangement can avoid the hard connection between the battery compartment 142 and the fixed bracket 1113 from being unable to adapt to the friction during the rotation of the battery compartment 142, and at the same time avoid repeated opening and closing to cause wear of the battery compartment 142 or the fixed bracket 1113. Furthermore, the positioning component 114 can further limit the motion trajectory, rotation angle and start and end positions of the rotation between the battery compartment 142 and the frame 11 on the basis of the assembly component 113, so as to ensure the stability of the flipping mechanism of the battery compartment 142 and the controllability of the motion trajectory.

[0034] Furthermore, the fixing bracket 1113 is at least partially located above the motor assembly 15, and the motor assembly 15 is fixedly connected to the fixing bracket 1113. This arrangement not only enables the battery assembly 14 to form a stable hard connection with the vertical bracket 1112 through the fixing bracket 1113, but also provides a support point for the upper end of the motor assembly 15, which is convenient for accommodating and placing the motor assembly 15, and makes the connection between the motor assembly 15 and the frame 11 more stable.

[0035] like Figure 3 As shown, the locking device 16 includes an execution component 161 and an operation component 162 (see Figure 2), optionally, the actuator 161 is arranged between the battery assembly 14 and the vertical support frame 1122, specifically, the actuator 161 includes a locking member 1611 and a fixing member 1612, the locking member 1611 includes a locking tongue whose opening and closing state can be controlled by the operating member 162, and the locking tongue can be controlled by the operating member 162 to realize the control of the connection state between the locking member 1611 and the fixing member 1612. The fixing member 1612 is arranged on the battery compartment 142 and fixedly connected to the battery compartment 142, and the locking member 1611 is arranged on the vertical support frame and fixedly connected to the vertical support frame. When the battery compartment 142 is in the storage state, the fixing member 1612 is at least partially located in the locking member 1611 and forms a fixed connection with the locking member 1611, ensuring that the battery compartment 142 cannot flip relative to the frame 11. When the power battery 141 needs to be disassembled or assembled, the locking tongue is operated accordingly through the operating assembly 162, so that the relative fixation between the locking member 1611 and the fixing member 1612 is released, and the battery compartment 142 is ejected to one side of the electric two-wheeled vehicle 100 under the action of the elastic member 1133 in the assembly assembly 113. According to the above description, the actuator assembly 161 is between the battery compartment 142 and the vertical support frame 1122, and can be used together with the positioning assembly 114 to limit the battery compartment 142 in the front and rear directions of the electric two-wheeled vehicle 100, and form a hard connection between the battery compartment 142 and the frame 11 in the length direction to avoid shaking or displacement in the length direction. Furthermore, the locking device 16 at least partially disposed between the battery compartment 142 and the vertical support frame 1122 can also realize the control of the state of the battery compartment 142 and the frame 11, that is, the battery compartment 142 in the open state is pushed back to the accommodating space S1 until the fixing member 1612 is at least partially located in the locking member 1611, and the locking device 16 realizes the width direction limitation of the battery compartment 142 in the storage state, so that the battery compartment 142 remains in the storage state. Furthermore, the operating component 162 is disposed on the body cover 12 located on the upper part of the vehicle, and the operating component 162 is connected to the execution component 161 by a cable 163 to realize the control of the execution component. The operating component 162 is at least partially disposed above the battery assembly 14. This arrangement is convenient for the driver to operate the operating component 162, and the unlocking process is more ergonomic.

[0036] It is understandable that other components can be provided between the battery compartment 142 and the vertical support frame 1122 to realize the hard connection and support between the two, or another positioning component 114 can be provided between the battery compartment 142 and the vertical support frame 1122 to realize the above functions, and the actuator component 161 can be provided at other parts of the electric two-wheeled vehicle 100, that is, the actuator component 161 only realizes the locking function and does not provide support in the length direction. Correspondingly, the operating component 162 can also be provided at other parts of the electric two-wheeled vehicle 100 according to the needs of the user. The control of the lock tongue can also be realized electronically between the operating component 162 and the actuator component 161.

[0037] like Figure 3 and Figure 5 As shown, the power battery 141 is arranged in the battery compartment 142, and is electrically connected to other electrical components through a main cable 143 at least partially arranged above the battery assembly 14. In order to further limit and fix the battery assembly 14 in the height direction, an elastic support member 115 is also arranged on the longitudinal bracket 1111 located above the battery assembly 14. When the battery compartment 142 is in an assembled state and the battery assembly 14 is located inside the battery compartment 142, the elastic support member 115 is at least partially located between the power battery 141 and the longitudinal bracket 1111, and an elastic preload is provided between the power battery 141 and the longitudinal bracket 1111, so as to realize the connection between the battery assembly 14 and the frame 11 in the height direction, and avoid the displacement of the power battery 141 relative to the battery compartment 142 under bumpy road conditions, causing damage to the power battery 141 or affecting driving safety. Specifically, the elastic support member 115 includes a support frame 1151 and an elastic member 1152 arranged on the support frame 1151. When the battery assembly 14 is in an assembled state, the support frame 1151 abuts against the power battery 141 through the elastic member 1152, thereby limiting the height direction of the power battery 141 and preventing the support frame 1151 with greater hardness from causing damage to the power battery 141. It can also adapt to power batteries 141 of different heights. Even if the power batteries 141 of different heights are replaced, a stable connection between the battery assembly 14 and the support frame 1151 can still be achieved.

[0038] like Fig. 6A and Figure 6BAs shown, after the power battery 141 is loaded into the battery compartment 142, the power battery 141 will follow the battery compartment 142 to flip to the storage state of the battery compartment 142, that is, the abutment state between the power battery 141 and the elastic support frame 1151 as described above. It can be understood that in order to keep the power battery 141 in a stable abutment state with the elastic support member 115 after being in the assembly state, when the battery compartment 142 is rotated to a certain preset angle, that is, before the battery compartment 142 has not completely entered the storage state, the elastic support member 115 and the power battery 141 have already contacted each other, and in the process of the battery compartment 142 continuing to rotate from the preset angle to the storage state, the upper end of the power battery 141 and the elastic support member 115 are in a relative friction state under a strong preload, so that the battery assembly 14 is switched to the storage state and the preload force between the elastic support member 115 is maintained. Based on this, in the present application, the elastic member 1152 in contact with the power battery 141 is set as a roller structure, that is, in the process of the battery compartment 142 continuing to flip from a preset angle to a storage state, the sliding friction between the power battery 141 and the elastic support member 115 is converted into rolling friction, so that the battery compartment 142 loaded with the power battery 141 can be easily switched to the storage state, and the sliding friction can be effectively avoided. Damage to the surface of the power battery 141 caused by friction can be effectively avoided.

[0039] like Figure 7 As shown, the body cover 12 of the electric two-wheeled vehicle 100 includes, in addition to the main cover 121 disposed above the vehicle frame 11, side guards 122 distributed along the width direction and basically disposed on the side of the electric two-wheeled vehicle 100. The side guards 122 are basically distributed on both sides of the battery assembly 14 along the width direction. Optionally, when viewed from the width direction of the electric two-wheeled vehicle 100, the side guards 122 and the battery assembly 14 are arranged to overlap at least partially. This arrangement can cover and protect the battery assembly 14 through the side guards 122. Furthermore, it can also constitute a further position limit for the battery assembly 14. Even if the battery assembly 14 is loosened due to the failure of the connecting components under extreme working conditions, the side guards 122 can further limit the battery assembly 14.

[0040] like Figure 8As shown, the electric two-wheeled vehicle 100 also includes a side support 116 for supporting the vehicle in a stationary state. As an optional embodiment, the flipping direction of the assembly component 113 is set to the opposite side of the setting direction of the side support 116, that is, when the battery compartment 142 is in an open state, the battery compartment 142 faces the side away from the side support 116. In the present application, the side support 116 is set on the left side of the frame 11 and is rotatably connected to the frame 11, so that the battery compartment 142 is reversed toward the right side in the open state. This setting method can ensure the reasonable arrangement of the center of gravity of the whole vehicle when the battery compartment 142 is in the open state, and avoid the overturning caused by the unstable center of gravity of the vehicle when the battery compartment 142 is in the assembled state. Furthermore, the side guard plate 122 set on the right side can also be set to be fixedly connected with the battery compartment 142, that is, when the battery compartment 142 is in an open state, the side guard plate 122 flips to the right side with the battery compartment 142. This setting method can make the opening and closing of the battery compartment 142 more convenient, and there is no need to set other opening methods for the side guard plate 122. It is understandable that in other embodiments, due to user needs or other requirements, the opening direction of the battery compartment 142 can also be set on other sides of the electric two-wheeled vehicle 100, as long as the power battery 141 can be quickly disassembled and installed.

[0041] Furthermore, in order to ensure the stable installation of the battery assembly 14, a flexible material is also provided inside the battery compartment 142, so that an interference fit is formed between the power battery 141 and the battery compartment 142, so that after the power battery 141 and the battery compartment 142 are in the assembled state, the power battery 141 cannot be displaced or shaken relative to the battery compartment 142, so as to avoid bumping the power battery 141 during riding and even causing the disconnection between the power battery 141 and the main cable 143. According to the above description, it can be understood that the shape of the battery compartment 142 does not need to be completely consistent with the power battery 141, as long as a stable connection between the power battery 141 and the battery compartment 142 can be achieved.
