Description

Technical Field

[0001] This utility model relates to the field of electric motorcycle battery unit technology, and more specifically, it relates to a disassembly and assembly structure for a front-mounted battery unit of a youth-oriented electric motorcycle. Background Technology

[0002] Currently, traditional electric motorcycles on the market are mainly fuel-powered. However, with industry development and market demand, electric motorcycles have become another important development direction for the motorcycle industry. Lithium batteries have developed rapidly in recent years, becoming the preferred core power source for electric motorcycles due to their high energy density, small size, light weight, and high continuous current.

[0003] The existing electric motorcycle batteries are inconvenient to install on the frame, and their stability and safety are not high, which can easily lead to the batteries becoming loose or falling off, thus affecting the user experience.

[0004] To address the aforementioned issues, Chinese Patent Publication No. CN219487639U discloses an electric motorcycle battery pack, comprising a battery pack, a frame, footrests, and side stand sheet metal. The frame is fixed to the top of the battery pack. A set of footrests is symmetrically installed at the rear of the frame. The side stand sheet metal is fixed to the bottom of the footrests and connected to the battery pack. The frame has a rectangular frame structure, with a front mounting point at the bottom front of the frame and a middle mounting point at the top center of the frame. The footrests have a crescent-shaped structure, with an upper mounting point on the top side and a lower mounting point on the bottom side. A set of footrest mounting points is provided on the surface of the side stand sheet metal.

[0005] The above solution can effectively improve the tightness and stability of the fixation between the battery pack and the vehicle frame, further preventing loosening or detachment. However, the battery pack installation in this solution is achieved through screws at multiple points, and the installation and removal of the battery requires external tools, making the process cumbersome and inconvenient.

[0006] Therefore, a solution needs to be proposed to address this problem. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a front battery unit disassembly and assembly structure for youth electric motorcycles. The battery module is disassembled and assembled by setting a mortise lock, and no external tools are needed during the disassembly and assembly process, making the disassembly and assembly of the battery module more convenient and efficient.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a front-mounted battery unit disassembly and assembly structure for a youth-oriented electric motorcycle, including a frame and a battery module disposed within the frame. The frame has a cavity formed for vertically inserting the battery module. The battery module includes an outer shell and a battery pack installed inside the outer shell. A cover is provided at the upper opening of the outer shell. A mortise lock is fixedly installed on the inner wall of the cover. A through hole is provided on the side wall of the cover. The lock cylinder of the mortise lock corresponds to the position of the through hole. The lock cylinder of the mortise lock is exposed on the surface of the cover through the through hole. A second through hole is provided on the side wall of the cover. The bolt of the mortise lock corresponds to the position of the second through hole. A locking hole is provided on the frame for inserting the bolt. When the mortise lock is locked, the bolt can pass through the second through hole and insert into the locking hole.

[0009] By adopting the above technical solution, under normal circumstances, the battery pack is installed inside the outer casing, and the cover is fixedly placed at the opening on the top of the outer casing, forming a complete battery module. When the battery module needs to be fixedly installed on the frame, the battery module is vertically inserted into the cavity formed by the frame from above. After placement, the frame has rods on all four sides of the battery module to limit its movement. The position of the second through hole corresponds to the position of the locking hole. At this time, the key is inserted into the lock cylinder of the mortise lock. After turning the lock cylinder, the bolt of the mortise lock can extend out from the mortise lock, pass through the second through hole, and lock into the locking hole. Pulling out the key prevents the battery module from being pulled upwards and detached from the frame, thus achieving the fixed installation of the battery module. Conversely, when the battery module needs to be removed from the frame, the key is reinserted into the lock cylinder and turned in the opposite direction to rotate the lock cylinder, causing the bolt to be pulled out of the latch and retract into the cover. Without the bolt limiting the movement, the battery module can be easily removed upwards. The installation and removal of the battery module do not require external tools, making the operation more convenient and efficient.

[0010] The present invention is further configured such that: a vertically arranged slide rail is fixedly connected to the inner wall of the frame; a limiting groove for the slide rail to be inserted is provided on the side wall of both the outer shell and the cover; the bottom wall of the limiting groove is in communication with the outside; and a through groove corresponding to the position of the through hole and the locking hole is provided on the side wall of the slide rail.

[0011] By adopting the above technical solution, when the battery module is inserted into the cavity from above the frame, the through slot will align with the slide rail. During the insertion process, the slide rail will be embedded in the through slot, making the alignment of the battery module with the locking hole more accurate during installation. After the battery module is completely placed into the cavity, the positions of the through hole, the through slot, and the locking hole correspond. When the mortise lock is turned, the bolt will extend from the through hole, pass through the through slot, and lock into the locking hole, making the connection between the battery module and the frame more stable.

[0012] The present invention is further configured such that: a base for receiving the battery module is fixedly connected inside the frame, the upper end face of the base is provided with a receiving groove, and the bottom of the outer shell is fixedly installed in the receiving groove.

[0013] By adopting the above technical solution, when the battery module is placed into the cavity, the bottom wall of the battery module will be placed into the receiving slot, which makes the positioning more accurate and the placement more stable. The base setting can play a certain buffering role, and provides better protection for the overall battery module.

[0014] The present invention is further configured such that: a controller connected to the battery pack is fixedly disposed on the inner wall of the cover, and a wiring port for connecting the controller is disposed on the side wall of the cover.

[0015] By adopting the above technical solution, the wiring port is equipped with a pluggable connector. When it is necessary to disassemble the battery module, no additional tools are needed. The pluggable connector that mates with the wiring port can be manually unplugged directly. At this time, the electrical connection between the wiring port and the pluggable connector is disconnected, and the circuit between the controller and the external system of the electric motorcycle is cut off. After the circuit is cut off, the battery pack can be directly removed from the mounting position of the electric motorcycle. The operation is convenient and efficient.

[0016] The present invention is further configured such that: a handle is provided on the upper end surface of the cover, and both ends of the handle are rotatably connected to the side wall of the cover.

[0017] By adopting the above technical solution, the handle makes it easier to pick up and carry the battery module, making it more convenient and labor-saving.

[0018] In summary, this utility model has the following beneficial effects:

[0019] This utility model uses a mortise lock to extend and retract the bolt, which cooperates with the through groove on the slide rail and the locking hole on the frame to realize the installation and removal of the battery module without the need for external tools, making the operation convenient and the installation and removal more efficient.

[0028] The present invention will now be described in detail with reference to the accompanying drawings.

[0029] A detachable battery unit structure for a youth-oriented electric motorcycle, such as... Figures 1-4As shown, the vehicle includes a frame 1 and a battery module housed within the frame 1. A chamber for vertically inserting the battery module is formed on the frame 1, located at the front end of the overall electric motorcycle frame 1. The battery module includes an outer shell 2 and a battery pack installed inside the outer shell 2. A cover 3 covers the upper opening of the outer shell 2. A mortise lock 4 is fixedly installed on the inner wall of the cover 3. A through hole 1 is provided on the side wall of the cover 3, and the lock cylinder 401 of the mortise lock 4 corresponds to the position of the through hole 1, with the lock cylinder 401 exposed on the surface of the cover 3 through the through hole 1. A second through hole 5 is provided on the side wall of the cover 3, and the latch 402 of the mortise lock 4 corresponds to the position of the second through hole 5. A locking hole 6 is provided on the frame 1 for the latch 402 to be inserted. When the mortise lock 4 is locked, the latch 402 can pass through the second through hole 2 5 and be inserted into the locking hole 6.

[0030] A vertically arranged slide rail 7 is fixedly connected to the inner wall of the frame 1. The side walls of the outer shell 2 and the cover 3 are provided with limiting grooves 8 for the slide rail 7 to be inserted. The bottom wall of the limiting groove 8 is open to the outside. The side wall of the slide rail 7 is provided with a through groove 9 corresponding to the position of the through hole 5 and the locking hole 6.

[0031] A base 10 for receiving the battery module is fixedly connected inside the frame 1. The upper surface of the base 10 has a receiving groove, and the bottom of the outer shell 2 is fixedly installed in the receiving groove. When the battery module is placed into the cavity, the bottom wall of the battery module will be placed into the receiving groove, which makes the positioning more accurate and the placement more stable. The base 10 can play a certain buffering role and provides better protection for the overall battery module.

[0032] A controller electrically connected to the battery pack is fixedly installed on the inner wall of the cover 3. The specific circuit connection method is a mature existing technology and will not be described in detail here. A wiring port 11 for connecting the controller is provided on the side wall of the cover 3. The wiring port 11 is equipped with a pluggable connector. When it is necessary to disassemble the battery module, no additional tools are needed. The pluggable connector that mates with the wiring port 11 can be manually unplugged. At this time, the electrical connection between the wiring port 11 and the pluggable connector is disconnected, and the circuit between the controller and the external system of the electric motorcycle is cut off. After the circuit is cut off, the battery pack can be directly removed from the mounting position of the electric motorcycle. The operation is convenient and efficient.

[0033] A handle 12 is provided on the upper surface of the cover 3, and both ends of the handle 12 are rotatably connected to the side wall of the cover 3. The handle 12 makes it easier to pick up and carry the battery module, making it more convenient and effortless.

[0034] The upper surface of the cover 3 has several arrayed heat dissipation holes. These holes improve the heat dissipation of the battery pack.

[0035] Working principle: Under normal circumstances, the battery pack will be installed inside the outer shell 2, and the cover 3 will be fixedly placed on the opening above the outer shell 2 to form a complete battery module. At this time, the locking tongue 402 of the mortise lock 4 will retract into the through hole 5 and will not protrude from the surface of the cover 3. When it is necessary to fix the battery module on the frame 1, align the limiting groove 8 on the battery module with the slide rail 7 and insert it vertically from above into the cavity formed by the frame 1, so that the battery module is placed stably on the base 10.

[0036] After placement, the frame 1 has rods on all four sides of the battery module to limit its movement, and the base 10's receiving groove further limits the bottom of the battery module, preventing horizontal displacement. At this point, the positions of through hole 2 5, through groove 9, and locking hole 6 are aligned. Then, the key is inserted into the lock cylinder 401 of the mortise lock 4. After turning the lock cylinder 401, the bolt 402 of the mortise lock 4 will extend, protruding from through hole 2 5, passing through through groove 9, and finally locking into locking hole 6. Removing the key leaves the bolt 402 in its extended state, preventing the battery module from being pulled upwards and detached from the frame 1, thus achieving a fixed installation of the battery module.

[0037] Conversely, when the battery module needs to be removed from the frame 1, insert the key back into the lock cylinder 401 and turn it in the opposite direction to rotate the lock cylinder 401, causing the latch 402 to be pulled out from the latch and through slot 9 and retracted into the cover 3. Without the limitation of the latch 402, the battery module can be easily removed upwards. The removal and installation of the battery module does not require external tools, making the maintenance and replacement of the battery module more convenient.

[0038] In the technical solution of this invention, the mortise lock body adopts a mortise lock body with the following characteristics found in the prior art: when the key is inserted into the lock cylinder and turned clockwise, the lock cylinder drives the bolt to extend in a preset direction until it is engaged in the locking hole, thus achieving locking; when unlocking is required, the key must be reinserted into the lock cylinder and turned counterclockwise to drive the bolt to retract and disengage from the locking hole; when no key is inserted and the bolt is turned counterclockwise, the bolt always remains extended from the locking hole and will not automatically retract. The selection and installation of this lock body allows this invention to achieve a stable locking effect without the need for an additional bolt limiting mechanism, simplifying the overall structure.

[0039] In practical implementation, those skilled in the art can directly select commercially available mortise lock bodies, fix the lock body to the cover body with bolts, align the bolt outlet of the lock body with the through hole, and ensure that the bolt can accurately engage with the locking hole after it extends. After assembly, insert the key into the lock cylinder and turn it in the forward direction, the bolt extends and engages with the locking hole to achieve locking; turn the key in the reverse direction, the bolt retracts and unlocks. Its operating logic is consistent with that of this type of mortise lock in the prior art, and no structural modification of the lock body is required. The basic working principle of this type of mortise lock (such as the cooperation between the key and the lock cylinder to drive the bolt extension and retraction) and core functions are well known to those skilled in the art and will not be elaborated here. For reference, see the KLC50 single-latch mortise lock, Huitailong 8881 or 5050 series single-latch lock bodies.

[0040] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected by this utility model. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
