Description

Technical Field

[0001] The utility model relates to the technical field of battery structures of electric motorcycles, and in particular to a battery structure for rapid battery replacement of electric motorcycles. Background Art

[0002] At present, in the structure of straddle-type electric motorcycles, lithium batteries and the like are used as the power source to drive the electric motorcycles. For electric motorcycles with traditional structures, once lithium batteries and other batteries are installed in the frame of the electric motorcycle, they are basically impossible to remove or it is very troublesome to remove them (because the batteries are relatively fixed in the frame and multiple times fixed). There is no corresponding fast battery replacement structure or battery replacement function. The user can only continue to ride after charging the battery when the battery power is low or the electric motorcycle has a short range. This will cause the electric motorcycle to wait for a long time to charge, resulting in the inability to achieve continuous range. The driving and use time of the electric motorcycle is limited, and the use functionality is single.

[0003] In the prior art, Chinese Patent No. 202021950364.3 discloses a patented technology of "a battery loading device for an electric motorcycle". This patent uses a rotating mechanism to realize the rotation of the box body and facilitate the removal of the battery in the box body; although this patented technical solution realizes the function of removing the battery, in actual use, this patented technical solution still has some shortcomings, as follows: (1) Whether the box 10 is fixed on the electric motorcycle or rotated by the rotating mechanism 30 to remove the battery 20, there are no corresponding protective devices such as guard plates, guard bars, and guard tubes on the outside and bottom of the box, only The battery is protected by the outer shell of the box. When an electric motorcycle collides or crashes, the most fatal cause of fire is damage to the battery. If the box is used to protect the battery, the protection of the battery will not be strong. The battery may be damaged and cause fire in the event of a traffic accident. The insufficient protection of the battery may lead to a large safety hazard. In particular, there is no protective device at the bottom of the box. When the electric motorcycle is traveling on a bumpy road or a road with many stones, the protruding stones may easily directly scrape the bottom of the box and the bottom of the battery, causing damage to the battery. (2) The box is installed on the motorcycle body by relying solely on the fixing frame 50, that is, there is only one fulcrum for installation and force. Such a structure will cause the box (which is heavier when equipped with a battery) to be unbalanced in installation force and easy to tear at the installation point after installation. In serious cases, the entire box and the battery may be accidentally detached. The safety risk is extremely high and there are great safety hazards. (3) It is difficult to remove the box after it is installed on the motorcycle body. When the box is deformed or damaged, it is necessary to destroy the box or disassemble the rotating mechanism, fixing frame, etc. in sequence. The disassembly is very inconvenient and troublesome, and fails to effectively simplify the maintenance or replacement of the box.

[0004] Therefore, it is necessary to make certain improvements to the battery and battery box structures of electric motorcycles in the prior art to improve the problems of the prior art, so as to develop an electric motorcycle battery structure that improves the protection strength of the battery box, improves safety, and facilitates and quickly replaces the battery. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings of the above-mentioned prior art and provide a battery structure for electric motorcycles with fast battery replacement. The battery structure for electric motorcycles with fast battery replacement adopts a novel battery box structure, which can charge the battery online or take out the battery for replacement, so as to realize the use of different needs and different scenes. The replaced battery can be charged separately, and the electric motorcycle can continue to run after the battery is replaced. The battery replacement time of a few minutes can achieve the continuity of the electric motorcycle's endurance, improve the utilization rate of electric vehicles, and better adapt to the market. The battery structure is provided with protective tube structures on the upper, middle, lower and outer sides of the battery box. All-round protection of the battery box is achieved, the protection performance and safety of the battery box are improved, and the heat dissipation of the battery and the battery box is not affected. In addition, the battery box and the frame are firmly installed by arranging elastic steel pipe fittings and the frame bottom plate. When the battery needs to be replaced, it is only necessary to loosen the screw connection between the frame bottom plate and the frame, and the elastic characteristics of the elastic steel pipe fittings can be used to push the battery box out from the frame, thereby realizing battery replacement. After the battery is replaced, the battery box is pushed back into the installation position of the frame, and the frame bottom plate and the frame are fixed with screws, thereby achieving the purpose of fast battery replacement and the battery box can be firmly installed on the frame when the battery is not replaced.

[0025] Example 1

[0026] The battery structure of an electric motorcycle with rapid battery replacement described in this embodiment 1 is as follows: Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9As shown, it includes a battery box 2 installed on the frame 1 and a battery 3 that is movably inserted into the battery box; the battery box includes a detachable box body 4, an upper box protection pipe 5 installed at the outer peripheral position of the upper part of the detachable box body, an outer box protection pipe 6 installed at the outer peripheral position of the outer side of the detachable box body, and a bottom box protection pipe 7 installed at the outer peripheral position of the bottom of the detachable box body; the outer box protection pipe and the bottom box protection pipe are connected with an elastic steel pipe 8 to form a movably installed connection with the frame; the bottom of the bottom box protection pipe is also connected to the bottom of the frame through a frame bottom plate 9; the battery is provided with a charging port and a quick-connect socket that forms a quick-connect plug with the high-voltage line quick-connect plug on the frame. The battery box is installed on the frame of a straddle-type electric motorcycle, specifically, at the position of the engine and part of the cylinder of the original fuel motorcycle (that is, the engine and cylinder of the traditional fuel motorcycle are replaced by batteries and motors). When the battery box does not need to be pushed out for battery replacement, it is fixed to the frame through elastic steel pipe fittings and a frame bottom plate (the frame bottom plate is mounted to the frame through movable screws), so that the outer side and the bottom of the battery box have force fulcrums to be firmly fixed on the frame, so that the battery box is firmly installed without the risk of displacement or falling out; when it is necessary to push out the battery box to remove the battery for battery replacement, the high-voltage wire quick-connect plug is pulled out from the quick-connect socket, the frame bottom plate is loosened and not mounted on the frame, and the elastic deformation feature of the elastic steel pipe fitting is utilized to push the battery box out of the frame, the old battery can be taken out and replaced with a fully charged battery, thus achieving a quick battery replacement effect. After battery replacement, the battery box is pushed back into the frame, the frame bottom plate is tightly fixed to the frame, the high-voltage wire quick-connect plug is inserted into the quick-connect socket to connect the power, and the entire battery replacement process can be completed. The removable square battery box features upper, outer, and bottom protection tubes, designed to reinforce the outer and bottom protection structures of the battery box. This provides a buffering effect during collisions, minimizing unexpected deformation or damage, and improving overall safety. The battery can be charged online on the electric motorcycle without battery replacement, or a rapid battery replacement mode can be used for continuous driving.

[0027] In this first embodiment, the elastic steel pipe comprises two symmetrically arranged spring tubes 10. The spring tube structure of the elastic steel pipe allows for both deformation and movement within a certain range, while also providing a high-strength support and installation function. This is perfectly suited for both secure installation and mobility during battery removal for battery replacement. Furthermore, the spring tubes offer a long service life and are not prone to breakage.

[0028] In this first embodiment, the upper casing protection tubes include an upper left protective tube 11 that spans the left side of the detachable casing and is fixedly mounted to the front and rear sides of the detachable casing, and an upper right protective tube 12 that spans the right side of the detachable casing and is fixedly mounted to the front and rear sides of the detachable casing. The upper left and upper right protective tubes are offset vertically and, when viewed from above, form a square frame to protect the upper outer side of the detachable casing. When the detachable casing is removed from the vehicle frame, the upper left and upper right protective tubes also serve as handles for lifting the entire detachable casing.

[0029] In this first embodiment, the outer casing tube includes an outer front casing 14 connected to the upper left casing via an outer front connecting frame 13, and an outer rear protective frame 15 connected to the upper right casing. Two outer front casings are provided, symmetrically arranged. The outer front casing and the outer rear protective frame respectively form protective structures for the front and rear ends of the detachable casing, effectively protecting the front and rear ends of the detachable casing from direct impact and providing a cushioning effect. Furthermore, the outer front casing is directly secured to the upper left casing via the outer front connecting frame, providing a stable mounting effect. The outer rear protective frame is directly secured to the upper right casing. In the event of a collision or accident, the front end of an electric motorcycle is typically the most vulnerable to impact and severe damage. Therefore, the dual outer front casings effectively enhance the protection of the front end of the detachable casing while also increasing its strength.

[0030] In this first embodiment, the bottom protective tube assembly includes a bottom protective tube 16 integrally bent from the outer front protective tube. The end of the bottom protective tube is connected and mounted to the bottom of the outer rear protective frame. Two bottom protective tubes are provided, and the frame connection base is fixedly mounted to the bottoms of the two bottom protective tubes. Because the detachable box has a certain weight when installed on the frame, the installation of the bottom protective tubes can enhance the strength and protection of the bottom of the detachable box, making it less likely to deform. In addition, when the electric motorcycle is traveling on bumpy roads or low-lying roads with many stones, the bottom protective tubes can prevent stones from directly scraping the bottom of the detachable box, protecting the bottom of the detachable box from direct impact.

[0031] In this first embodiment, the top of the spring tube is fixedly connected to the vehicle frame. A middle spring tube connecting frame 17 is provided between the middle portions of the two spring tubes, interconnecting the two spring tubes and connecting them to the top of the outer rear protective frame. A spring tube support pipe 18 is provided between the middle and lower portions of the two spring tubes, connecting and fixing the two spring tubes. A lower spring tube connecting frame 19 is provided between the lower portions of the two spring tubes, connecting the two spring tubes to each other and connecting them to the bottom of the outer rear protective frame and the end of the bottom protective pipe. The middle spring tube connecting frame is mounted and connected to the top of the outer rear protective frame, connecting the middle of the spring tubes to the upper portion of the detachable housing. The spring tube support pipe tightly connects the two spring tubes, allowing them to deform and fix together, improving the compactness of the overall structure. The lower spring tube connecting frame is mounted and connected to the bottom of the outer rear protective frame and the bottom protective pipe, connecting the bottom of the spring tubes to the lower portion of the detachable housing. Since the spring tube has a certain elasticity and can produce a certain deformation, after the top of the spring tube is installed with the frame and the frame bottom plate is also fixed to the frame, the entire detachable box can be firmly installed on the frame, so that the upper, middle and lower parts of the detachable box have force-bearing installation fulcrums, thereby achieving the purpose of stable installation; when the detachable box needs to be pushed out, the frame bottom plate is loosened and no longer fixed to the frame, and the elastic characteristics of the spring tube can be used to realize the pushing out of the entire detachable box.

[0032] In Example 1, the battery box is mounted on the vehicle frame at a forward-tilted angle. Since the engine and cylinder block of a conventional gasoline-powered motorcycle are both tilted forward, the battery box replaces the engine and cylinder block, maintaining the majority of the original vehicle structure without major structural modifications. This allows the battery box to be positioned forward-tilted, ensuring a well-matched fit with the vehicle frame.

[0033] In this embodiment 1, the outer side of the spring tube is further tightly covered with a spring tube protective sleeve. The spring tube protective sleeve can well protect the spring tube from corrosion by dust, water, oil and gas, etc., thereby improving the protection performance of the spring tube.

[0034] In this embodiment 1, the battery structure of the electric motorcycle with rapid battery replacement adopts a novel battery box structure, which can be used for online charging or battery replacement mode of removing the battery, realizing the use of different needs and different scenarios. The replaced battery is charged separately, and the electric motorcycle can continue to drive after the battery is replaced. The continuity of the electric motorcycle's endurance can be achieved with a battery replacement time of a few minutes, thereby improving the utilization rate of electric vehicles and being more adaptable to the market. The battery structure is provided with protective tube structures on the upper, middle, lower and outer sides of the battery box, which realizes all-round protection of the battery box, improves the protection performance and safety of the battery box, and does not affect the heat dissipation of the battery and the battery box. In addition, the battery box and the frame are firmly installed by providing elastic steel pipe fittings and a frame bottom plate. When the battery needs to be replaced, it is only necessary to loosen the screw connection between the frame bottom plate and the frame, and the elastic characteristics of the elastic steel pipe fittings can be used to push the battery box out of the frame to realize the battery replacement. After the battery is replaced, the battery box is pushed back into the installation position of the frame, and the frame bottom plate is fixed to the frame with screws, thereby achieving the purpose of rapid battery replacement and the battery box being firmly installed on the frame when the battery is not replaced.

[0035] The above description is only a preferred embodiment of the present invention and does not constitute any formal limitation on the structure of the present invention. Any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
