Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of a detachable battery pack structure, and more particularly to an electric motorcycle battery pack structure that allows for quick installation and removal of the battery pack from an electric motorcycle. Background Technology
[0002] In recent years, battery packs installed on electric motorcycles have been fixedly mounted on the frame. Once installed, they are generally difficult to remove or require special tools to remove. They usually need to be removed and installed at designated repair shops. This is to prevent the battery pack from easily coming off, protect the connection between the battery pack and high-voltage lines, and prevent battery pack accidents. When the battery pack needs to be charged, the electric motorcycle can be ridden to a designated charging place to charge the battery pack. However, such electric motorcycle battery pack structure has certain problems in actual use, as follows: (1) Since the battery pack is basically not removable, the battery pack has a low power level and cannot meet the needs of continuous driving. It can only be charged, and the charging time is at least 30 minutes. This results in the inability to continue using the electric motorcycle while waiting for charging, and the continuous driving can not be achieved, which limits the use and fails to increase the continuous driving ability. That is, there is no function to continue driving with a fully charged battery pack, and it does not have a battery swapping function. (2) The battery pack is installed on the frame by a battery bracket. Since the battery pack is generally square in shape, traditional battery brackets are made of box-like or frame-like structures to fix the battery pack, or four corner brackets combined with a base plate. Such fixing methods not only make the battery bracket structure complex and heavy, but also make the installation process cumbersome and troublesome. In addition, the battery needs to be installed inside the battery bracket, which makes it difficult to install conveniently and quickly in the narrow installation space of the frame, increasing the installation difficulty.
[0003] Therefore, improvements are needed to the battery pack structure of existing electric motorcycles to solve the aforementioned problems. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a battery pack structure for an electric motorcycle. This battery pack structure uses a simple and space-saving battery support plate for the movable installation of the battery pack. The battery support plate is firmly installed on the frame, while the battery pack is movably installed on the battery support plate and locked in place by latches and hooks. This allows the battery pack to be movably installed within the frame and quickly disassembled as needed for rapid battery swapping. After a quick battery swap, extended driving range can be maintained without waiting for charging, facilitating long-term use of the electric motorcycle. The battery pack removed after swapping can be detached from the electric motorcycle and moved to other locations for charging, which is convenient and quick. The battery pack can be charged online on the electric motorcycle (without removing the battery pack) via a waterproof charging socket, or it can be moved to a charging facility for charging after being removed from the electric motorcycle. The connector socket allows for quick connection and disconnection of the battery pack to the connector plug on the frame, facilitating power connection between the battery pack and the electric motorcycle, and also facilitating quick disconnection of the battery pack from the connector plug.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a battery pack structure for an electric motorcycle, including a battery support plate mounted on the frame and having a square shape, and a battery pack movably mounted on the battery support plate.

The top three outer surfaces of the battery carrier plate are provided with limiting protrusions for limiting the installation of the battery pack. The top of two of the limiting protrusions extends upward with a locking mounting plate. The outer side of the locking mounting plate is equipped with a locking buckle that can be movably locked to the outside of the battery pack.
[0007] The battery pack has a hook on the outside that engages with the latch, and a waterproof charging socket and a connector socket on the outside of the battery pack.
[0008] Furthermore, the top of the battery pack is provided with an upward handle that can lift the battery pack upwards, and the outside of the battery pack is provided with an outer handle that can pull the battery pack out laterally from the battery support plate.
[0009] Furthermore, the battery carrier plate, which does not have a limiting protrusion skirt, has a downwardly extending reinforcing skirt on one of its outer sides.
[0010] Furthermore, both the front mounting bracket and the rear mounting bracket are arch-shaped structures, and each of the front mounting bracket and the rear mounting bracket has mounting holes at its lower position to form a bracket installation.
[0011] Furthermore, the latch includes a latch fixing plate fixedly mounted on the latch mounting plate, a handle hinged to the latch fixing plate, and a handle locking plate fixedly mounted below the latch fixing plate and capable of passing through the handle; one end of the handle is provided with a latching hole bracket that forms a movable locking hook with the hook, and the other end of the handle has a handle slot that allows the handle locking plate to pass through, and the latching hole bracket is fixedly mounted on the handle by a fixing shaft; the handle locking plate is provided with a latching hole.
[0012] Furthermore, the hook is formed by an integral structure of a U-shaped hook opening and a hook connecting piece.
[0013] Furthermore, the waterproof charging socket is equipped with a waterproof cover for sealing.
[0014] Furthermore, the battery pack is a diamond shape that is tilted forward.
[0015] In summary, the battery pack structure of this utility model for an electric motorcycle utilizes a simple and space-saving battery support plate for the movable installation of the battery pack. The battery support plate is securely mounted on the frame, while the battery pack is movably mounted on the battery support plate and locked in place by latches and hooks. This allows the battery pack to be movably installed within the frame and quickly disassembled as needed for rapid battery swapping. After a quick battery swap, extended range can be maintained without waiting for charging, facilitating prolonged use of the electric motorcycle. The battery pack removed during swapping can be detached from the electric motorcycle and moved to other locations for charging, offering convenience and speed. The battery pack can be charged online on the electric motorcycle (without removing the battery pack) via a waterproof charging socket, or it can be moved from the electric motorcycle to a charging facility for charging. The connector socket allows for quick connection and disconnection of the battery pack to the connector plug on the frame, facilitating power connection between the battery pack and the electric motorcycle and enabling quick disconnection of the connector plug after battery pack removal.

Detailed Implementation
[0023] Example 1
[0024] The battery pack structure of an electric motorcycle described in Embodiment 1 is as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the system includes a square-shaped battery carrier plate 1 mounted on the vehicle frame and a battery pack 2 movably mounted on the battery carrier plate. The battery pack can be quickly mounted on the vehicle frame using only one battery carrier plate. The battery carrier plate has a simple structure, making it convenient and quick to install on the vehicle frame without taking up space, and the installation process is easy. The battery pack is movably mounted on the battery carrier plate and can be quickly removed from the battery carrier plate as needed for rapid battery swapping. Furthermore, the removed battery pack is easy to carry and can be moved to any corresponding charging location for charging, expanding the charging scenarios.
[0025] The battery carrier plate has a front mounting bracket 3 and a rear mounting bracket 4 fixedly installed at its bottom to form a mounting fit with the vehicle frame and are distributed in a front-to-back manner. Three outer surfaces at the top of the battery carrier plate extend upwards to provide limiting protrusions 5 for battery pack installation. Two of these limiting protrusions extend upwards to a locking mounting plate 6, with a movable locking buckle 7 on the outer side of the locking mounting plate to lock the outer side of the battery pack. The battery carrier plate is securely mounted on the vehicle frame via the front and rear mounting brackets, allowing for horizontal installation and stable mounting with mounting points at both the front and rear. One outer side of the battery carrier plate lacks a skirt. This design allows the three limiting protrusions to block the three corresponding bottom sides of the battery plate, providing positioning and limiting for battery pack installation. When the battery pack needs to be removed, it can be smoothly pulled out from the side without the skirt, achieving quick installation and easy removal.
[0026] The battery pack has a hook 8 on its outer side that engages with the latch for a movable locking mechanism. It also has a waterproof charging socket 9 and a connector socket 11 on its outer side. The battery pack can be quickly installed and removed from the battery support plate by locking or releasing the latch and hook. When the latch and hook are locked, the battery pack is securely and stably mounted on the battery support plate by the limiting protrusion skirt. When the latch and hook are released, the battery pack can be pulled out of the battery support plate without locking or limiting its position. The waterproof charging socket on the battery pack provides good waterproofing when not charging and allows for quick connection and plugging during charging. The connector socket allows for quick connection and disconnection with the connector plug on the vehicle frame, ensuring safe use of the connector socket.
[0027] In this embodiment 1, the battery pack has an upper handle 12 at the top for lifting upwards, and an outer handle 13 on the outside for pulling the battery pack laterally out of the battery support plate. When the battery pack is no longer locked to the battery support plate, the entire battery pack can be pulled out of the battery support plate using the outer handle, achieving the purpose of disassembling the battery pack. After the battery pack is disassembled, the entire battery pack can be lifted and moved to other places using the upper handle, achieving the purpose of convenient carrying and lifting of the battery pack. When the battery pack is fully charged and needs to be replaced and installed on the battery support plate, the battery pack is lifted, pushed into the battery support plate, and finally locked to complete the installation of the battery pack.
[0028] In this embodiment 1, the outer side of the battery support plate without the limiting protruding skirt is provided with a downwardly extending reinforcing skirt 14. Since the side without the limiting protruding skirt must not only bear the side weight of the battery pack, but also the frictional load during each installation and removal of the battery pack, the downwardly extending reinforcing skirt can enhance the strength of this side, making it more robust and less prone to deformation.
[0029] In this embodiment 1, both the front and rear mounting brackets are arch-shaped structures. Each bracket has mounting holes 15 at its lower part to facilitate installation. The shape of the front and rear mounting brackets allows for direct insertion into the mounting positions on the vehicle frame. The mounting holes overlap with the corresponding mounting holes on the frame, and screws are then inserted from outside the frame into these holes for secure installation. This not only simplifies installation but also saves space on the vehicle frame, requiring only the space needed for the battery carrier.
[0030] In this embodiment 1, as Figure 5As shown, the latch includes a latch fixing plate 16 fixedly mounted on the latch mounting plate, a handle 17 hingedly mounted on the latch fixing plate, and a handle locking plate 18 fixedly mounted below the latch fixing plate and through which the handle can pass; one end of the handle is provided with a latching bracket 19 that forms a movable locking hook with the hook, and the other end of the handle is provided with a handle slot 20 that allows the handle locking plate to pass through, and the latching bracket is fixedly mounted on the handle by a fixing shaft 21; the handle locking plate is provided with a latching hole 22. The entire latch can be securely installed on the latch mounting plate by means of the latch fixing plate. When the handle is pulled down, the latch hole bracket is also pulled down. When pulled to the designated position, the latch hole of the latch hole bracket can lock onto the hook to form a lock. The handle locking plate passes through the handle slot and can be locked by a locking bar, ordinary chain, padlock, or combination lock to achieve the purpose of anti-theft of battery pack. When the latch is disengaged from the hook, the above lock can be released and the handle can be lifted up to disengage the latch hole bracket from the hook, so that the battery pack can be quickly pulled out.
[0031] In this embodiment 1, the hook is formed by a U-shaped hook opening 23 and a hook connecting piece 24 forming an integral structure.
[0032] In this embodiment 1, the waterproof charging socket is provided with a waterproof cover 25 for sealing.
[0033] In this embodiment 1, the battery pack structure of the electric motorcycle uses a simple and space-saving battery support plate for the movable installation of the battery pack. The battery support plate is firmly installed on the frame, while the battery pack is movably installed on the battery support plate and locked in place by latches and hooks. This allows the battery pack to be movably installed in the frame and quickly removed as needed for rapid battery swapping. After a quick battery swap, the motorcycle can continue to operate for extended periods without waiting for charging, facilitating long-term use. The battery pack removed from the motorcycle can be moved to other locations for charging, which is convenient and quick. The battery pack can be charged online on the electric motorcycle (without removing the battery pack) via a waterproof charging socket, or it can be moved to a charging facility for charging after being removed from the electric motorcycle. The connector socket allows for quick connection and disconnection of the battery pack to the connector plug on the frame, facilitating power connection between the battery pack and the electric motorcycle, and also facilitating quick disconnection of the battery pack from the connector plug.
[0034] Example 2
[0035] This embodiment 2 is based on embodiment 1, with changes specifically to the shape and structure of the battery pack, as detailed below:
[0036] In this embodiment 2, as Figure 6As shown, the battery pack is a diamond shape tilted forward. Traditional battery packs and the battery in Embodiment 1 are square in shape and have conventional dimensions; however, the battery pack in Embodiment 2 is a slightly tilted diamond shape, meaning that the battery pack is installed at a forward tilt when mounted on the battery support plate, so that the overall battery pack is installed slightly downward. This design ensures that the original vehicle frame engine mounting position does not require major modifications, perfectly adapting to the original vehicle frame and saving the cost of modifying the vehicle frame.
[0037] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the structure of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
