Description

Technical Field

[0001] This invention belongs to the field of electric motorcycle technology, and specifically relates to an easy-to-use electric motorcycle charger. Background Technology

[0002] The drive motor of an electric motorcycle is powered by an onboard power supply. Currently, the most widely used power source in electric motorcycles is lead-acid batteries or lithium-ion batteries. When the battery's stored power is depleted or falls below a preset threshold, it needs to be charged to restore its power supply capacity. Electric motorcycles are equipped with a charging port, which is electrically connected to the battery. When charging, the charging plug of an external charging device can be directly inserted into the charging port to charge the battery.

[0003] However, a common problem exists when charging electric motorcycles: due to limited parking space, vehicles often cannot be parked near charging sockets, resulting in excessive distance between the socket and the charging port. Since the charger's cable length is fixed, this contradiction often puts the charger in a dilemma – either it's suspended in the air, where the cable is easily strained and pulled, leading to loose connections, poor contact, or even damage, affecting charging safety and efficiency; or it's forced to be placed directly on the ground. This situation contradicts the daily habits and psychological perceptions of many Chinese people. From a cultural and hygiene perspective, even if the ground appears clean, people generally consider it a "convergence zone" of dust, moisture, and potential pollution. Placing the charger directly on the ground exposes it to moisture, dust, and accidental impacts, potentially causing electrical short circuits, accelerated component aging, and other safety hazards, shortening its lifespan. This unavoidable placement not only brings actual safety risks but also causes discomfort and concerns in the user experience. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing an easy-to-use electric motorcycle charger. The technical problem to be solved by this invention is: how to make the charger safer, more convenient, and more in line with user habits.

[0005] The above-mentioned technical objective of the present invention can be achieved through the following technical solution: an easy-to-use electric motorcycle charger, comprising a charger body and a housing, wherein the charger body is detachably disposed inside the housing, and two opposing support blocks are rotatably disposed at the bottom of the housing, each of the two support blocks being threadedly connected with two screws, and the bottom of each of the two screws being provided with an anti-slip support portion, wherein the bottom of the housing is provided with a groove for accommodating and hiding the two support blocks and the corresponding screws, and each support block can be rotated to a state perpendicular to the bottom of the housing, thereby causing the screws to disengage from the grooves and be in a state perpendicular to the bottom of the housing.

[0006] In the aforementioned easy-to-use electric motorcycle charger, heat-absorbing bodies are detachably provided on both opposite sides inside the housing. The heat-absorbing bodies are filled with heat-absorbing phase change material, and the phase change temperature of the heat-absorbing phase change material is 50°C to 80°C.

[0007] In the aforementioned easy-to-use electric motorcycle charger, ventilation openings are provided on the other opposite sides inside the housing. Several guide vanes made of heat-conducting material are rotatably arranged inside the ventilation openings, and each of the guide vanes can change its angle by rotating.

[0008] In the aforementioned easy-to-use electric motorcycle charger, when the support block rotates to a state perpendicular to the bottom of the housing, the support block can drive several of the guide vanes to rotate to a predetermined angle through a linkage component, thereby forming directional convection air ducts on both sides of the housing. When the support block rotates into the groove and is parallel to the bottom of the housing, the support block can drive several of the guide vanes to rotate into a streamlined shape through a linkage component, and the several guide vanes will block the corresponding ventilation openings.

[0009] In the aforementioned easy-to-use electric motorcycle charger, the linkage component includes a first gear, several second gears, and a double-sided rack. The first gear is coaxially arranged with the shaft of the support block, and the several second gears are coaxially arranged with the shafts of the corresponding guide vanes. The first gear meshes with one side of the double-sided rack, and the several second gears mesh with the other side of the double-sided rack.

[0010] In the aforementioned easy-to-use electric motorcycle charger, a cavity is provided inside the housing, and a take-up reel for winding the connecting cable is rotatably disposed inside the cavity. A cable passage is provided on the housing to connect the outside world with the cavity.

[0011] In the aforementioned easy-to-use electric motorcycle charger, a locking structure, an unlocking component, and a reset torsion spring are provided within the cavity. The locking structure is used to lock the take-up reel, thereby restricting the rotation of the take-up reel along the direction of winding the connecting line. When the support block rotates into the groove and is parallel to the bottom of the housing, the support block drives the unlocking component to release the locking structure from locking the take-up reel, thereby causing the reset torsion spring to drive the take-up reel to rotate and reset along the direction of winding the connecting line, thus winding the connecting line.

[0012] In the aforementioned easy-to-use electric motorcycle charger, the locking structure includes a ratchet, a pawl, and a return spring. The ratchet is coaxially connected to the take-up reel. The pawl is rotatably disposed within the cavity and engages with the ratchet. A positioning pin is provided within the cavity. One end of the return spring is connected to the pawl, and the other end of the return spring is connected to the positioning pin. The return spring is used to rotate and return the pawl to the ratchet tooth groove of the ratchet.

[0013] In the aforementioned easy-to-use electric motorcycle charger, the unlocking component is disposed at the end of the double-sided rack, and a linkage block is disposed on the pawl. The linkage block has an inclined surface on one side corresponding to the unlocking component, and the unlocking component abuts against the inclined surface. When the double-sided rack moves and drives the unlocking component to move, the pawl is pushed away from the ratchet groove of the ratchet.

[0014] In the aforementioned easy-to-use electric motorcycle charger, a rubber ring is detachably provided on the side wall of the housing, the wire passage is disposed inside the rubber ring, and a flexible bristle layer that converges towards the center is evenly distributed circumferentially inside the rubber ring, and the rubber ring limits the plug of the connecting wire.

[0015] In summary, the advantages of this invention compared to the prior art are as follows:

[0016] 1. The charger body is located inside the housing, which protects the charger body from external bumps and impacts. When in use, rotate the two support blocks to a position perpendicular to the bottom of the housing. At the same time, the corresponding screws will disengage from the grooves and be in a position perpendicular to the bottom of the housing. Through the coordinated support of the two support blocks and the corresponding screws, the charger body is prevented from directly contacting the ground, thus preventing dust and water stains from the ground from contaminating the charger body and affecting its service life. This effectively solves the adverse effects caused by the charger being suspended or directly in contact with the ground in the existing technology.

[0017] 2. The screw is threaded to the support block. The extension length can be adjusted by rotating the screw in the forward or reverse direction. This not only allows it to quickly adapt to uneven ground, but also ensures stable support by adjusting the extension length of the screw, preventing shaking during charging.

[0018] 3. Users only need to rotate the support block to simultaneously open or close the directional convection air duct, without any additional operation steps, greatly improving ease of use. When the directional convection air duct is open, it can work with the heat-absorbing body filled with heat-absorbing phase change material to quickly remove the heat generated by the charger body during operation. When the directional convection air duct is closed, it can prevent external dust from entering the housing through the vents, and prevent dust from accumulating on the surface of the heat-absorbing body to form a heat insulation layer that affects subsequent heat dissipation efficiency, thus achieving the dual effect of heat dissipation and protection.

[0019] 4. The locking and unlocking of the take-up reel can be triggered simultaneously by rotating the support block. No additional operation steps are required. Rotating the support block to the support position will enable the locking structure to lock the take-up reel in one direction. Users can pull out the connecting cable as needed and maintain its length stably, preventing the plug from falling off due to the cable rebound during charging. Rotating the support block to the storage position will automatically release the lock on the take-up reel. The reset torsion spring will drive the take-up reel to complete the automatic winding of the connecting cable, solving the problem of messy tangled connecting cables and inconvenient storage.

[0028] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0029] An easy-to-use electric motorcycle charger, such as Figures 1 to 7As shown, the device includes a charger body 1 and a housing 2. The charger body 1 is detachably disposed inside the housing 2. Preferably, the charger body 1 is detachably fixed inside the housing 2 by bolts (not shown). Alternatively, the charger body 1 can also be snapped into the housing 2 by a snap-fit ​​structure, which facilitates the disassembly and maintenance of the charger body 1 in the future.

[0030] In this embodiment, the housing 2 includes an outer shell 21 and a cover 22. The cover 22 is placed over the opening of the outer shell 21 to seal the opening of the outer shell 21, thereby preventing external dust and water stains from directly entering the interior of the housing 2 and contacting the charger body 1.

[0031] The bottom of the housing 2 is rotatably provided with two opposing support blocks 3. Specifically, the two support blocks 3 are rotatably connected to the housing 2 through corresponding rotating shafts. Two screws 4 are threadedly connected to each of the two support blocks 3. The bottom of each screw 4 is provided with an anti-slip support part 5. Preferably, the anti-slip support part 5 is made of wear-resistant rubber material to increase the friction with the ground, prevent slipping, and improve stability.

[0032] The bottom of the housing 2 is provided with a groove 6 for accommodating and hiding two support blocks 3 and corresponding screws 4. The anti-slip support part 5 is accommodated and hidden in the groove 6. The support blocks 3 can rotate to a state perpendicular to the bottom of the housing 2, and drive the screws 4 to disengage from the groove 6 and be perpendicular to the bottom of the housing 2. The screws 4 drive the anti-slip support part 5 to disengage from the groove 6.

[0033] It should be noted that in the unfolded support state, the support block 3 is now perpendicular to the bottom of the housing 2 by rotation. At the same time, the screw 4 is disengaged from the groove 6 and perpendicular to the bottom of the housing 2 by the support block 3. At this time, the extension length can be adjusted by rotating the screw 4 in the forward or reverse direction, so as to accurately adapt to different placement scenarios or uneven ground. This not only ensures the stability of the support, but also greatly improves the flexibility of use. In this state, the housing 2 is supported by the two support blocks 3 and the corresponding screw 4 and anti-slip support part 5. By relying on the coordinated support of the two support blocks 3 and the corresponding screw 4 and anti-slip support part 5, the charger body 1 is prevented from directly contacting the ground, preventing dust and water stains from the ground from contaminating the charger body 1 and affecting its service life. This can effectively solve the adverse effects caused by the charger being suspended or directly contacting the ground in the prior art.

[0034] In the retracted state, rotating the screw 4 to its shortest extension length causes the support block 3 to rotate and be hidden inside the receiving groove. Simultaneously, the support block 3 drives the screw 4 to rotate and be hidden inside the receiving groove, and the screw 4 drives the anti-slip support part 5 to be hidden inside the receiving groove. This state facilitates carrying and storage, and effectively avoids the risk of collision, scratch damage to the support block 3, screw 4, and anti-slip support part 5 when they are exposed in non-use situations.

[0035] The heat-absorbing body 7 is detachably installed on both opposite sides inside the shell 2. The heat-absorbing body 7 is filled with heat-absorbing phase change material with a phase change temperature of 50°C to 80°C. The heat-absorbing body 7 is a heat-conducting metal shell with a hollow cavity. Preferably, the heat-absorbing body 7 is detachably fixed inside the shell 2 by bolts (not shown). Alternatively, the heat-absorbing body 7 can also be snapped into the shell 2 by a snap-fit ​​structure. This facilitates the disassembly and maintenance of the heat-absorbing body 7, making it easier to inspect or replace the aging phase change material and extend its service life.

[0036] When the charger body 1 generates heat during operation and transfers it to the heat-absorbing body 7, the heat is absorbed by the phase change material inside. When the internal temperature of the housing 2 reaches the melting point temperature of the phase change material, the phase change material begins to change from solid to liquid. During this process, a large amount of heat is absorbed, thereby rapidly reducing the temperature inside the housing 2 and the charger body 1, preventing the charger body 1 from degrading in performance or aging of components due to excessive temperature. When the charger body 1 stops working and the temperature drops back to the freezing point temperature of the phase change material, the phase change material changes from liquid to solid, releasing the stored heat and restoring its heat absorption capacity, thus achieving cyclic use.

[0037] Ventilation openings 8 are provided on the other two opposite sides inside the housing 2. Several guide vanes 9 made of heat-conducting material are rotatably arranged inside the ventilation openings 8. The guide vanes 9 are evenly arranged in the vertical direction. The guide vanes 9 can change their angle by rotating. When the support block 3 rotates to a state perpendicular to the bottom of the housing 2, the support block 3 can drive the guide vanes 9 to rotate to a predetermined angle through the linkage component 10, thereby forming directional convection air channels on both sides of the housing 2. When the support block 3 rotates into the groove 6 and is parallel to the bottom of the housing 2, the support block 3 can drive the guide vanes 9 to rotate into a streamlined shape through the linkage component 10, and the guide vanes 9 block the corresponding ventilation openings 8.

[0038] When the support block 3 rotates to the unfolded support state perpendicular to the bottom of the housing 2, the support block 3 drives several guide vanes 9 to rotate to a predetermined angle through the corresponding linkage component 10. The adjacent guide vanes 9 form a uniform airflow channel, thereby forming a directional convection airflow channel on both sides of the housing 2. When the charger body 1 starts charging and generates heat, the heat will be quickly transferred to the housing 2, the guide vanes 9 and the heat-absorbing body 7 to absorb heat through the phase change material. At the same time, when there is airflow from the outside through the convection airflow channel, the airflow will carry away the heat absorbed by the guide vanes 9, the housing 2, the heat-absorbing body 7 and the phase change material. This not only significantly improves the overall heat dissipation efficiency, but also accelerates the phase change material from liquid to solid state, allowing it to quickly restore its heat absorption capacity and ensure a continuous and stable heat absorption capacity in the future.

[0039] Conversely, when the support block 3 rotates and is stored in the groove 6, the support block 3 drives several guide vanes 9 to rotate into a streamlined shape through the linkage component 10 and block the ventilation opening 8. The convection air duct is closed simultaneously. In this state, the charger does not charge. The residual heat inside the shell 2 can be slowly dissipated through the heat absorption body 7, the guide vanes 9 and the heat conduction of the shell 2. At the same time, the guide vanes 9 can block external dust from entering the shell 2 through the ventilation opening 8, and prevent the heat absorption body 7 from accumulating dust on its surface to form a heat insulation layer that affects the subsequent heat dissipation efficiency, thus achieving the dual effect of heat dissipation and protection.

[0040] The linkage component 10 includes a first gear 101, several second gears 102, and a double-sided rack 103. The first gear 101 is coaxially arranged with the rotating shaft of the support block 3. The several second gears 102 are coaxially arranged with the rotating shaft of the corresponding guide vanes 9. The double-sided rack 103 is slidably arranged through a corresponding guide structure. The first gear 101 meshes with one side of the double-sided rack 103, and the several second gears 102 mesh with the other side of the double-sided rack 103.

[0041] When the user rotates the support block 3, the support block 3 drives the corresponding rotating shaft and gear 101 to rotate. Gear 101 drives the double-sided rack 103 to move. The double-sided rack 103 drives several gears 102 to rotate. The several gears 102 drive the corresponding guide vanes 9 and their rotating shafts to rotate, so that the guide vanes 9 rotate to a predetermined angle to form a directional convection air duct or to be streamlined to block the ventilation opening 8. It should be noted that the user can drive several guide vanes 9 to rotate simultaneously by rotating the support block 3. No additional operation or drive source is required. That is, the user only needs to rotate the support block 3 to complete the unfolding or retracting action, and the directional convection air duct can be opened or closed simultaneously. The operation steps are simplified and the ease of use is greatly improved.

[0042] It should be noted that since users can flexibly adjust the extension length of the screw 4 by rotating it in the forward or reverse direction, thereby adjusting the height of the housing 2, it provides ample space for the directional convection air duct, making it suitable for various placement scenarios such as indoors, corridors, and garages, and making it more flexible to use.

[0043] The housing 2 has a cavity inside, and a take-up reel 12 for winding the connecting wire is rotatably installed inside the cavity. The housing 2 has a wire passage 13 that connects the outside to the cavity. The axis of the wire passage 13 is consistent with the tangent direction of the wire groove of the take-up reel 12, so as to ensure that the winding or pulling out of the connecting wire is smooth and without jamming.

[0044] Specifically, a rubber ring 18 is detachably provided on the side wall of the housing 2. Preferably, the rubber ring 18 is threadedly connected to the housing 2. Alternatively, the rubber ring 18 can be plugged into the housing 2 to facilitate the later disassembly and maintenance of the rubber ring 18. The wire passage 13 is located inside the rubber ring 18.

[0045] The cavity is equipped with a locking structure 14, an unlocking component 11, and a return torsion spring 16. The locking structure 14 is used to lock the take-up reel 12, thereby restricting the take-up reel 12 from rotating along the direction of the winding connecting line. Specifically, in this embodiment, the locking structure 14 includes a ratchet 142, a pawl 143, and a return tension spring 144. The ratchet 142 is coaxially connected to the take-up reel 12. The pawl 143 is rotatably disposed in the cavity. A mounting plate is provided in the cavity. One end of the pawl 143 is rotatably disposed on the mounting plate. The pawl 143 engages with the ratchet 142. A positioning pin is provided on the mounting plate. One end of the return tension spring 144 is connected to the pawl 143, and the other end of the return tension spring 144 is connected to the positioning pin. The return tension spring 144 is used to rotate the pawl 143 back into the ratchet groove of the ratchet 142.

[0046] The pawl 143 locks the ratchet 142 in one direction, thereby achieving one-way locking of the take-up reel 12. This restricts the rotation of the take-up reel 12 in the winding direction but does not interfere with its rotation in the unwinding direction. When the user pulls the connecting cable with external force, the take-up reel 12 will rotate to unwind the cable, overcoming the preload of the reset torsion spring 16. After the connecting cable is released, the pawl 143 immediately engages with the ratchet groove of the ratchet 142, preventing the take-up reel 12 from reversing. This ensures that the connecting cable can be stably maintained at the required length after being pulled out, preventing the plug from falling off due to the cable springback during charging.

[0047] The unlocking component 11 is located at the lower end of the double-sided rack 103. A linkage block 17 is provided on the pawl 143. The linkage block 17 has an inclined surface 15 on one side corresponding to the unlocking component 11. The unlocking component 11 abuts against the inclined surface 15. The part where the unlocking component 11 abuts against the inclined surface 15 is semi-circular. When the double-sided rack 103 moves and drives the unlocking component 11 to move, the pawl 143 is pushed away from the ratchet groove of the ratchet wheel 142. That is, the double-sided rack 103 drives the unlocking component 11 to move upward. The unlocking component 11 abuts against the inclined surface 15. Through the abutting action of the two, the pawl 143 is pushed to rotate away from the ratchet groove of the ratchet wheel 142. At this time, the lock on the ratchet wheel 142 is released, and the lock on the take-up reel 12 is released.

[0048] When the support block 3 rotates into the groove 6 and is parallel to the bottom of the housing 2, the support block 3 drives the unlocking component 11 to release the locking structure 14 from locking the take-up reel 12, thereby causing the reset torsion spring 16 to drive the take-up reel 12 to rotate and reset in the direction of winding the connecting wire to wind up the connecting wire. The reset torsion spring 16 is sleeved on the support shaft of the take-up reel 12, with one end of the reset torsion spring 16 connected to the support shaft and the other end of the reset torsion spring 16 connected to the take-up reel 12.

[0049] When the rotating support block 3 completes the unfolding action, the support block 3 drives the corresponding rotating shaft and gear 101 to rotate. Gear 101 drives the double-sided rack 103 to move vertically upward along the corresponding guide structure. The double-sided rack 103 simultaneously drives the unlocking part 11 at the end to move vertically upward and abut against the inclined surface 15 of the linkage block 17. As the double-sided rack 103 continues to move, the unlocking part 11 pushes the pawl 143 away from the ratchet groove of the ratchet wheel 142. At this time, under the action of the reset torsion spring 16, the take-up reel 12 rotates to wind up the connecting wire and drives the ratchet wheel 142 to rotate, thereby automatically winding up the connecting wire. This not only makes it convenient for users to use and eliminates the need to tidy up the connecting wire, but also protects the connecting wire by placing it in the cavity after winding.

[0050] It should be noted that there are corresponding connecting wires on both sides of the charger. Therefore, there are two of each of the following: the take-up reel 12, the locking structure 14, the unlocking component 11, the linkage block 17, and the reset torsion spring 16, which correspond one-to-one with the two support blocks 3. That is, by rotating the two support blocks 3 to change their state, the corresponding connecting wires can be unloaded and wound up.

[0051] Furthermore, a flexible bristle layer 19 is evenly distributed circumferentially inside the rubber ring 18, converging towards the center. The connecting line passes through the rubber ring 18, and the bristle ends of the flexible bristle layer 19 adhere to the outer surface of the connecting line.

[0052] The rubber ring 18 limits the plug of the connecting cable. Specifically, the inner diameter of the rubber ring 18 is smaller than the outer diameter of the plug. The plug at the end of the connecting cable cannot pass through the rubber ring 18. That is, the plug will be stopped at the outer end of the rubber ring 18, preventing the connecting cable from being completely wound into the take-up reel 12. This ensures that the plug can be directly grabbed and the connecting cable pulled out when used next time. This not only protects the connecting cable from being wound up, but also facilitates subsequent cable unwinding.

[0053] It should be noted that during the process of pulling out or rewinding the connecting wire, the flexible bristle layer 19 can play a central guiding role for the connecting wire, avoiding damage caused by hard contact. At the same time, when rewinding the connecting wire, the bristle layer can scrape off dust, mud and other impurities attached to the surface of the wire, keeping the connecting wire clean and achieving self-cleaning of the connecting wire. In addition, the bristle layer can prevent external dust, mud and other impurities from entering the cavity.

[0054] The specific embodiments described herein are merely illustrative of the spirit of the invention; those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, but without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
