Description

Technical Field

[0001] This utility model relates to the field of motorcycle technology, and more specifically, to an electric motorcycle frame with a quick-change battery. Background Technology

[0002] Electric motorcycles are two-wheeled vehicles powered by onboard rechargeable batteries, driven by electric motors. They are widely used for daily commuting and short-distance delivery due to their advantages such as low noise, zero emissions, and low operating costs. As a core power component, the battery's installation stability and ease of use directly affect the vehicle's overall performance. Currently, the mainstream installation method involves placing the battery in a specially designed battery compartment within the motorcycle frame. To prevent initial displacement of the battery during driving, a positioning structure is typically used for fixation—commonly either a locking mechanism or bolt fastening—ensuring the battery remains in its pre-set position within the battery compartment (e.g., preventing the battery from popping out of the compartment opening).

[0003] However, the current battery compartment design presents significant inconveniences in practical operation, particularly during battery replacement. Because the battery compartment opening is located above the motorcycle frame and is directly covered by the riding stool, users must first remove or lift the stool to access the battery, adding an extra step. For users who frequently need to swap batteries (such as delivery riders), this design significantly prolongs the time required for each swap, reduces travel efficiency, and may even negatively impact the user experience in emergencies due to the cumbersome operation.

[0004] More importantly, the size mismatch between the battery and the battery compartment leads to serious stability issues. To facilitate battery insertion and removal, the battery compartment is designed to be slightly larger than the battery itself, inevitably creating a gap between them. During electric motorcycle operation, especially on bumpy roads, the battery will bounce freely relative to the frame within the battery compartment. This irregular shaking not only causes repeated friction between the battery casing and the inner wall of the battery compartment, potentially leading to component wear and shortening battery life over time, but also may cause the battery's connection to the vehicle's power supply interface to loosen due to continuous vibration, resulting in poor contact, power outages, and even, in extreme cases, safety risks, threatening vehicle safety. Summary of the Invention

[0005] The purpose of this invention is to provide an electric motorcycle frame with a quick-change battery, aiming to solve the technical problems mentioned in the background art.

[0006] The embodiments of this utility model are implemented as follows: This application provides an electric motorcycle frame with a quick-change battery, comprising: a frame body with a battery mounting compartment for accommodating a battery pack, the opening of which is located on the left or right side of the frame body for inserting or removing the battery pack; a lock including a lock body and a latch that cooperate with each other, the lock body being disposed on the frame body and the latch being disposed on the outer side wall of the battery pack for restricting its movement along the left and right directions of the frame body after installation; and a clamping structure including a clamping member and an adjusting member, the clamping member being vertically movable above the battery mounting compartment for vertically positioning the battery pack installed in the battery mounting compartment, and the adjusting member being connected to the clamping member for adjusting the vertical movement of the clamping member.

[0007] Furthermore, based on the aforementioned solution, the adjusting component includes: an annular cylinder disposed on the frame body and sleeved on the clamping component; a handle rotatably disposed on the frame body; and a connecting component that drivesly connects the handle to the clamping component.

[0008] Furthermore, based on the aforementioned scheme, a rubber pad is provided on the bottom side of the clamping component.

[0009] Furthermore, based on the aforementioned scheme, a rubber sleeve is fitted onto the handle.

[0010] Furthermore, based on the aforementioned design, a handle is provided on the battery pack.

[0011] Furthermore, based on the aforementioned solution, the handle is hinged to the outer wall of the battery pack, and the outer wall of the battery pack is provided with a receiving groove for folding and storing the handle.

[0012] Furthermore, based on the aforementioned solution, the outer wall of the battery pack is provided with a plug-in block, and the battery mounting compartment is provided with a limiting member for engaging with the plug-in block. When the battery pack is fully inserted into the battery installation compartment, the plug-in block and the limiting member abut against each other.

[0013] Compared with the prior art, the embodiments of this utility model have at least the following advantages or beneficial effects: (1) In this application, the battery installation compartment opening is designed on the left or right side of the frame body. Compared with the traditional battery compartment opening being above the frame and covered by the riding stool, the side opening completely eliminates the extra steps of disassembling or lifting the stool when swapping batteries.

Detailed Implementation

[0018] The embodiments of this application will now be described in detail with reference to the accompanying drawings. Example

[0019] Please refer to Figure 1-8 This application provides an electric motorcycle frame with a quick-change battery, comprising: a frame body 1, having a battery mounting compartment 7 for accommodating a battery pack 2, the opening of the battery mounting compartment 7 being located on the left or right side of the frame body 1 for inserting or removing the battery pack 2; a lock 8, including a lock body 801 and a lock tongue 802 that cooperate with each other, the lock body 801 being disposed on the frame body 1, and the lock tongue 802 being disposed on the outer side wall of the battery pack 2 for restricting its movement along the left and right directions of the frame body 1 after the battery pack 2 is installed; and a clamping structure, including a clamping member 13 and an adjusting member, the clamping member 13 being vertically movable above the battery mounting compartment 7 for vertically positioning the battery pack 2 installed in the battery mounting compartment 7, and the adjusting member being connected to the clamping member 13 for adjusting the vertical movement of the clamping member 13.

[0020] The technical solution of this application addresses the critical impact of battery installation stability and ease of use on the overall performance of electric motorcycles. It designs a dedicated battery compartment on the motorcycle frame as a battery carrying space, precisely placing the on-board rechargeable battery inside the compartment. At the same time, it adopts a positioning structure with 8 locking and clamping structures. Through physical locking and mechanical fastening, it restricts the displacement of the battery during vehicle operation, ensuring that the battery is always in the preset position of the battery compartment, providing a stable guarantee for battery installation from the basic structural perspective. Its advantages are significant: First, the battery compartment 7 is designed with its opening on the left or right side of the frame body 1. Compared to the traditional design where the battery compartment opening is on top of the frame and covered by the riding seat, the side opening completely eliminates the extra steps of disassembling or lifting the seat when swapping batteries. Users do not need to perform complicated disassembly operations; they can simply insert the battery pack 2 into the compartment from the side of the frame or remove it from the side. The operation path is simpler and the action is more direct, greatly reducing the complexity of battery swapping operations. Even users unfamiliar with complex mechanical operations can easily complete the task. Second, in the left and right direction, the locking body 801 on the frame body 1 cooperates with the locking tongue 802 on the outer wall of the battery pack 2 to precisely restrict the left and right movement of the battery pack 2 along the frame, preventing the battery from rubbing against the inner wall of the battery compartment 7 due to left and right shaking during riding, or causing the power supply interface wiring to loosen. In the up and down direction, with the help of the vertically adjustable clamping part 13 and the adjusting part, the position of the clamping part 13 can be flexibly adjusted according to the height of the battery pack 2, achieving a stable vertical positioning of the battery pack 2 installed in the compartment and preventing the battery from wearing down due to vertical jumping.

[0021] In a preferred embodiment, the adjustment member includes: an annular cylinder 12, disposed on the frame body 1 and sleeved on the clamping member 13; a handle 9, rotatably disposed on the frame body 1; and a connecting member 11, which drivesly connects the handle 9 and the clamping member 13.

[0022] In the above embodiment, the annular cylinder 12 is fixed to the frame body 1 and sleeved with the clamping member 13, providing a vertical lifting guide constraint for the clamping member 13 and preventing lateral displacement when the clamping member 13 moves; when it is necessary to adjust the height of the clamping member 13, the user rotates the flexibly rotating handle 9, and the rotational movement of the handle 9 is converted into the vertical linear movement of the clamping member 13 through the transmission connection connector 11. If the handle 9 is rotated clockwise, the connector 11 drives the clamping member 13 to move downward along the annular cylinder 12, thereby achieving vertical clamping of the battery pack 2; if the handle 9 is rotated counterclockwise, the connector 11 pulls the clamping member 13 upward along the annular cylinder 12, releasing the constraint on the battery pack 2 for easy removal.

[0023] Specifically, the two ends of the connector 11 are hinged to the handle 9 and the clamping member 13 respectively, and a slot is provided at the hinge position with the clamping member 13. The slot can accommodate the rotation and small movement requirements of the clamping member 13 during the movement relative to the connector 11, which not only ensures the stability of the transmission connection between the two, but also reserves sufficient space for the posture adjustment of the clamping member 13 when it is raised and lowered vertically, thus avoiding the problem of motion jamming caused by rigid connection.

[0024] Preferably, the outer circumferential surface of the annular cylinder 12 is provided with locking bolts for adjusting the locking of the clamping member 13.

[0025] In a preferred embodiment, a rubber pad 14 is provided on the bottom side of the clamping member 13.

[0026] In the above embodiment, a rubber pad 14 is provided on the bottom side of the clamping member 13. The rubber's softness can prevent the clamping member 13 from being scratched and damaged by direct rigid contact with the outer shell of the battery pack 2. The high coefficient of friction of the rubber can also enhance the tightness of the fit with the battery pack 2 to reduce vertical swaying. Furthermore, the elasticity of the rubber can buffer the bumps and vibrations during vehicle operation, thus ensuring the stability of the vertical positioning of the battery pack 2 and the safety of its use in multiple dimensions.

[0027] In a preferred embodiment, a rubber sleeve 10 is fitted onto the handle 9.

[0028] In the above embodiment, a rubber sleeve 10 is fitted onto the handle 9. This not only enhances the grip friction between the hand and the handle 9 by utilizing the high coefficient of friction of the rubber, thus preventing the operation efficiency and safety from being affected by slipping during rotation and adjustment, but also cushions the force of the hand rotation through the elasticity of the rubber, reducing hand fatigue caused by frequent adjustments. It also isolates the handle 9 from the transfer of heat and cold (such as preventing it from being too hot to handle after being exposed to the sun in summer or too cold to handle in winter), while protecting the handle 9 from wear and tear, thus comprehensively improving the operating experience and component durability.

[0029] As a preferred embodiment, the battery pack 2 is provided with a handle 3.

[0030] In the above embodiment, the battery pack 2 is provided with a handle 3, which has the advantage of making it easy for users to grip and apply force. Whether inserting or removing the battery pack 2 from the battery installation compartment 7 on the side of the frame, it can avoid the difficulty of gripping due to the smooth surface or weight of the battery pack 2, and effectively reduce the risk of the battery pack 2 slipping during the picking and putting process.

[0031] In a preferred embodiment, the handle 3 is hinged to the outer side wall of the battery pack 2, and the outer side wall of the battery pack 2 is provided with a receiving groove 4 for folding and storing the handle 3.

[0032] In the above embodiment, the outer wall of the battery pack 2 is hinged to a handle 3 and has a receiving groove 4. When in use, the handle 3 can be unfolded for easy gripping to improve the convenience of battery swapping operation. When not in use, the handle 3 can be folded and stored in the receiving groove 4 to avoid bumps and damage caused by the handle 3 protruding. At the same time, it reduces space occupation to ensure the smooth insertion of the battery pack 2 into the battery installation compartment 7, and also keeps the outer wall of the battery pack 2 flat, taking into account both practicality and structural compactness.

[0033] In a preferred embodiment, the outer wall of the battery pack 2 is provided with a plug-in block 6, and the battery mounting compartment 7 is provided with a limiting member 5 for engaging with the plug-in block 6. When the battery pack 2 is fully inserted into the battery mounting compartment 7, the insertion block 6 and the limiting member 5 abut against each other.

[0034] In the above embodiment, the outer wall of the battery pack 2 is provided with a plug-in block 6 and the battery installation compartment 7 is provided with a limiting member 5, and the two abut against each other after the battery pack 2 is fully inserted. This can not only accurately ensure that the battery pack 2 is installed in place, but also quickly confirm the installation status through the abutting cooperation, save extra inspection steps to improve battery swapping efficiency, prevent the battery pack 2 from being over-inserted and causing collision damage to the components inside the compartment, and help limit the displacement of the battery pack 2 in the compartment, further enhancing the installation stability during driving.
