Description

Technical Field

[0001] This invention relates to the field of rainproof technology for battery pack charging and swapping boxes, specifically a rainproof device for battery pack charging and swapping boxes. Background Technology

[0002] As time goes by, electric vehicles on the market are also undergoing a transformation. From initially focusing on transportation, to gradually demanding more in terms of appearance while still providing basic transportation, to in recent years, fingerprint unlocking, smart apps, automatic reversing, and other personalized and intelligent functions have become cool selling points for many models. Electric vehicles seem to have reached the point where they meet many people's expectations.

[0003] However, the biggest pain point regarding electric vehicles, compared to the convenience of gasoline vehicles where refueling takes only a few minutes and the range can extend for hundreds of miles, has yet to be perfectly overcome in terms of range.

[0004] Existing companies, through their intelligent battery swapping models, have shown us more possibilities for the future development of electric vehicles! This new energy replenishment method, essentially based on battery sharing and interactive power consumption through leasing, uses intelligent battery swapping stations to replace and replenish batteries. This not only accurately addresses the current pain point of short driving range in electric vehicles, but also allows electric vehicles to replenish energy anytime, just like gasoline vehicles!

[0005] Existing charging and swapping boxes typically have a roof-like rainproof structure on top to prevent rainwater from entering the box during battery pack replacement. This could cause short circuits in the internal wiring, leading to damage to the charging and swapping box, severely affecting its lifespan and stability, and creating safety hazards. Summary of the Invention

[0006] The technical problem of the present invention is to provide a rainproof device for a battery pack charging and swapping box.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a rainproof device for a battery pack charging and swapping box, comprising a box body, characterized in that: a rainproof roof with a conical mechanism is fixedly connected to the top of the box body, a telescopic rainproof plate is slidably connected to the rainproof roof, a base is fixedly connected to the bottom of the box body, battery storage slots are provided on both sides of the box body, a battery storage box is slidably connected in the battery storage slots, a locking mechanism for locking the battery storage box is installed in the battery storage box, a parking platform is slidably connected to the bottom of the base, a return spring is fixedly connected between the parking platform and the base, a trigger rack for driving the telescopic rainproof plate to move and a trigger plate for unlocking the locking mechanism are installed in the box body, and a speed regulating mechanism for adjusting the transmission ratio of the trigger rack is installed on the side wall of the box body;

[0008] The speed regulating mechanism includes a transmission gear meshing with a trigger rack, a small speed regulating gear meshing with the transmission gear, a large speed regulating gear coaxially and fixedly connected to the small speed regulating gear, a reversing gear meshing with the large speed regulating gear, a transmission bevel gear coaxially and fixedly connected to the reversing gear, a driven bevel gear meshing with the transmission bevel gear, a transmission shaft coaxially and fixedly connected to the driven bevel gear, and a driven gear meshing with a telescopic rain shield extending from the top of the transmission shaft to the top of the housing and fixedly connected to the top of the transmission shaft.

[0009] The locking mechanism includes a locking sleeve fixedly connected to the battery storage slot, a locking slider slidably connected inside the locking sleeve, a locking spring fixedly connected between the bottom of the locking slider and the locking sleeve, a locking rod fixedly connected to the top of the locking slider passing through the locking sleeve, a telescopic slider slidably connected inside the locking slider, a telescopic spring fixedly connected between the telescopic slider and the locking slider, an electromagnet and an iron sheet fixedly connected to the locking slider and the telescopic slider respectively, and an inductor coil sleeved on the charging cable connected to the electromagnet.

[0010] When the electric scooter rides onto the parking platform, the platform descends under gravity. The platform's compression return spring simultaneously drives the trigger rack and trigger plate, which are fixedly connected to it, to descend. As the trigger rack descends, it also drives the telescopic rain shield to extend outward.

[0011] As a further embodiment of the present invention, the side of the base is provided with an oblique angle to facilitate the electric vehicle to go up and down, and the surface of the oblique angle is provided with an anti-slip groove.

[0012] As a further embodiment of the present invention, the base is provided with a mounting groove for mounting a parking platform, and a drainage groove is provided at the bottom of the mounting groove.

[0013] As a further embodiment of the present invention, the side wall of the housing is provided with a side groove for installing the adjustment mechanism, and a maintenance plate is fixedly connected to the surface of the side groove by bolts.

[0014] As a further embodiment of the present invention, there are multiple battery storage boxes and battery storage slots, and the battery storage box is fixedly connected with a handle.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] In this invention, when changing the battery pack, the weight of the electric vehicle presses down on the parking platform. The parking platform, through a trigger rack, drives the telescopic rain shield to extend from its rain-shielding top, thereby increasing the rain-shielding area of ​​the device. Simultaneously, the trigger plate unlocks the locking mechanism, allowing the battery storage box to be pulled out. After replacing the battery pack, a return spring lifts the parking platform, causing the telescopic rain shield to retract into the rain-shielding top, reducing the top area of ​​the device and lowering its resistance to strong winds. This prevents the device from being blown away by strong winds, thus avoiding damage and increased maintenance costs. It also prevents rainwater from entering the battery swapping box during battery pack replacement, which could cause short circuits in the internal wiring, damaging the swapping box and severely impacting its lifespan and stability, creating safety hazards. When the trigger plate disengages from the locking mechanism, the locking mechanism locks the battery storage box within the battery storage slot, preventing it from being ejected by external force and preventing rainwater from entering the device. This further prevents damage to the swapping box, ensuring its lifespan and stability are protected from safety hazards. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-7 The present invention provides a technical solution comprising: a housing 1, a rain shield 2 with a conical mechanism fixedly connected to the top of the housing 1, a telescopic rain shield 21 slidably connected to the rain shield 2, a base 3 fixedly connected to the bottom of the housing 1, battery storage slots 11 on both sides of the housing 1, a battery storage box 12 slidably connected in the battery storage slots 11, a locking mechanism for locking the battery storage box 12 installed in the battery storage box 12, a parking platform 5 slidably connected to the bottom of the base 3, a return spring 51 fixedly connected between the parking platform 5 and the base 3, a trigger rack 52 for driving the telescopic rain shield 21 to move and a trigger plate 54 for unlocking the locking mechanism installed in the housing 1, and a speed regulating mechanism for adjusting the transmission ratio of the trigger rack 52 installed on the side wall of the housing 1;

[0029] During operation, the electric scooter requiring a battery pack replacement is mounted on the parking platform 5. The parking platform 5 descends under gravity, compressing the return spring 51 and simultaneously causing the trigger rack 52 and trigger plate 54, which are fixedly connected to it, to descend. The descent of the trigger rack 52 also drives the telescopic rain shield 21 to extend outward, increasing the rain protection area. During the descent of the trigger plate 54, the locking mechanism is unlocked, allowing the battery storage box 12 to be pulled out. A fully charged battery storage box 12 is located and pulled out, allowing the electric scooter's battery pack and battery to be connected. The battery in the storage box 12 is replaced. After the battery pack is replaced, the battery is stored and pushed into the battery storage slot 11. Finally, the electric vehicle behind the battery is ridden off the parking platform 5. The return spring 51 extends, causing the parking platform 5 to rise. The parking platform 5 drives the trigger rack 52 and trigger plate 54 to rise. The trigger rack 52 rises, causing the telescopic rain shield 21 to retract into the rain shield top 2. This can reduce the overall size of the device, reduce the resistance to strong winds, and prevent strong winds from blowing the device, causing damage and increasing the cost of equipment maintenance.

[0030] In this invention, when replacing the battery pack, the weight of the electric scooter acts as a force to press down the parking platform 5. The parking platform 5, through the trigger rack 52, drives the telescopic rain shield 21 to extend out of the rain shield top 2, thereby increasing the rain-shielding area of ​​the device. At the same time, the trigger plate 54 unlocks the locking mechanism, allowing the battery storage box 12 to be pulled out. After replacing the battery pack, the return spring 51 lifts the parking platform 5, causing the telescopic rain shield 21 to retract into the rain shield top 2, reducing the top area of ​​the device, lowering the resistance to strong winds, and preventing the device from being blown over by strong winds, thus avoiding damage to the device and increasing its safety. The cost of equipment maintenance is addressed by preventing rainwater from entering the battery swapping box during battery pack replacement, which could cause short circuits in the internal wiring, damage the battery swapping box, severely impact its lifespan and stability, and create safety hazards. When the trigger plate 54 disengages from the locking mechanism, the locking mechanism locks the battery storage box 12 within the battery storage slot 11, preventing the battery storage box 12 from being ejected by external force and preventing rainwater from entering the device. This further prevents damage to the battery swapping box, ensuring its lifespan and stability are protected and avoiding safety hazards.

[0031] As a further embodiment of the present invention, the speed regulating mechanism includes a transmission gear 61 meshing with a trigger rack 52, a small speed regulating gear 68 meshing with the transmission gear 61, a large speed regulating gear 62 coaxially and fixedly connected to the small speed regulating gear 68, a reversing gear 63 meshing with the large speed regulating gear 62, a transmission bevel gear 64 coaxially and fixedly connected to the reversing gear 63, a driven bevel gear 65 meshing with the transmission bevel gear 64, a transmission shaft 66 coaxially and fixedly connected to the driven bevel gear 65, and a transmission shaft 66 extending to the top of the housing 1 and fixedly connected to a driven gear 67 meshing with the telescopic rain shield 21.

[0032] When the electric scooter is mounted on the parking platform 5, the rack 52 is triggered to descend, driving the transmission gear 61 to rotate. The transmission gear 61 drives the small speed-regulating gear 68 to rotate, which in turn drives the coaxially mounted large speed-regulating gear 62 to rotate. The large speed-regulating gear 62 drives the reversing gear 63 to rotate, which in turn drives the driven bevel gear 65 to rotate via the transmission bevel gear 64, completing the reversing drive. The driven bevel gear 65 drives the driven gear 67 to rotate via the transmission shaft 66, which in turn drives the telescopic rain shield 21 to move outward from the rain shield top 2, increasing the rain shielding range. Since the small speed-regulating gear 68 and the large speed-regulating gear 62 are coaxially mounted, the descent distance of the parking platform 5 can be amplified, and the telescopic rain shield 21 can be pushed outward, thereby further increasing the rain shielding range and the rain shielding effect.

[0033] As a further embodiment of the present invention, the locking mechanism includes a locking sleeve 4 fixedly connected in the battery storage slot 11, a locking slider 41 slidably connected in the locking sleeve 4, a locking spring 42 fixedly connected between the bottom of the locking slider 41 and the locking sleeve 4, a locking rod 43 fixedly connected to the top of the locking slider 41 passing through the locking sleeve 4, a telescopic slider 44 slidably connected in the locking slider 41, a telescopic spring 45 fixedly connected between the telescopic slider 44 and the locking slider 41, an electromagnet 46 and an iron sheet 47 fixedly connected to the locking slider 41 and the telescopic slider 44 respectively, and an inductor coil sleeved on the charging cable is electrically connected to the electromagnet 46.

[0034] During operation, when the battery pack in the battery storage box 12 is charging, the inductor coil will activate the circuit, energizing the electromagnet 46. When the electromagnet 46 is energized, it can attract the iron plate 47. The iron plate 47 drives the telescopic slider 44 to move into the locking slider 41. When the trigger plate 54 descends, it cannot contact the telescopic slider 44, thus preventing the locking rod 43 from being pulled down, and therefore the locking mechanism cannot be released. Consequently, the battery storage box 12 cannot be pulled out. Conversely, when the battery pack in the battery storage box 12 has finished charging, the electromagnet 46 is de-energized, and the telescopic spring 45 will pull the telescopic slider 44... When the trigger plate 54 descends, it can pull the telescopic slider 44 downward, causing the locking slider 41 to descend. The locking slider 41 compresses the locking spring 42, and at the same time pulls the locking rod 43 downward. The locking rod 43 disengages from the battery storage box 12, allowing it to be pulled out. This ensures that after the electric bicycle is mounted on the parking platform 5, the battery storage box 12 corresponding to the charging battery pack cannot be pulled out, while the battery storage box 12 corresponding to the fully charged battery pack can be pulled out. This avoids the need to replace an incompletely charged battery pack, which would shorten the riding distance, increase the frequency of battery pack replacement, and reduce the user's experience.

[0035] As a further embodiment of the present invention, the base 3 is provided with an oblique angle 31 on the side to facilitate the electric vehicle to go up and down, and the surface of the oblique angle 31 is provided with an anti-slip groove 32.

[0036] When in operation, the angle 31 makes it easy for the electric vehicle to get on and off the base 3, and the anti-slip groove 32 can increase the friction between the wheel and the base 3, so that the wheel will not slip and be unable to ride on the base 3 after the angle 31 gets wet, which would increase the difficulty of replacement.

[0037] As a further embodiment of the present invention, the base 3 is provided with a mounting groove 33 for mounting the parking platform 5, and a drainage groove 34 is provided at the bottom of the mounting groove 33.

[0038] During operation, the drainage channel 34 can drain the rainwater flowing into the installation channel 33 along the parking platform 5, preventing rainwater from accumulating in the base 3. If rainwater accumulates for a long time, it will cause a foul smell, resulting in an odor around the device and reducing the experience of replacing the battery pack.

[0039] As a further embodiment of the present invention, a side groove 7 for installing an adjustment mechanism is provided on the side wall of the housing 1, and a maintenance plate 8 is fixedly connected to the surface of the side groove 7 by bolts.

[0040] During operation, the inspection plate 8 can facilitate the inspection of the speed regulation mechanism in the side groove 7, reducing the difficulty of inspection.

[0041] As a further embodiment of the present invention, there are multiple battery storage boxes 12 and battery storage slots 11, and the battery storage box 12 is fixedly connected with a handle 9.

[0042] When in operation, handle 9 facilitates the pulling out and pushing in of the battery storage box 12.
