Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, specifically to an outdoor waterproof lithium battery device. Background Technology

[0002] Outdoor lithium batteries are widely used as portable energy sources in outdoor lighting, emergency equipment, camping tools, and other scenarios. Due to the complex and changeable outdoor environment, especially in the face of harsh conditions such as rain and humidity, reliable protection of the lithium battery terminals has become a key issue to ensure their safe and stable operation.

[0003] In existing technologies, waterproofing measures for cable connectors largely rely on manually fastened protective covers. Firstly, manually operated covers often suffer from incomplete closures. When used outdoors, continuous cable movement can cause the cover to slip open, creating gaps that allow rainwater to seep in. Secondly, these traditional structures generally lack effective self-locking mechanisms, failing to maintain a stable, sealed state under vibration. Furthermore, for traditional structures where the cable outlet is located at the bottom of the cover, straight-insertion cables require significant bending to pass through. This inefficient cable routing is not only inconvenient but also prone to damaging the cable, affecting its lifespan and potentially posing safety hazards.

[0004] An outdoor waterproof lithium battery device is proposed to address the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide an outdoor lithium battery waterproof device to address the aforementioned issues raised in the background section. In existing technologies, waterproofing of the wiring ports often relies on manually fastened protective covers. Firstly, manually operated covers often fail to close tightly, and during outdoor use, continuous cable movement can cause the cover to slide open, creating gaps that allow rainwater to seep in. Secondly, these traditional structures generally lack effective self-locking mechanisms, making it impossible to maintain a stable, sealed state under vibration. Furthermore, for traditional structures where the cable outlet is located at the bottom of the cover, straight-insertion cables require significant bending to pass through, which is not only inconvenient but also prone to damaging the cable, affecting its lifespan and potentially posing safety hazards.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an outdoor lithium battery waterproof device, comprising an outdoor lithium battery body, wherein a lighting lamp and a wiring port are installed on one side of the outdoor lithium battery body;

[0007] A waterproof component is provided on the outside of the wiring port. The waterproof component includes a pair of mounting protrusions. A connecting shaft is symmetrically rotatably connected to one side of the mounting protrusions. A synchronous gear is sleeved on the outside of the connecting shafts. An upper connecting ring and a lower connecting ring are respectively fixedly connected to the ends of the upper and lower connecting shafts away from the mounting protrusions.

[0008] The upper connecting ring has a bellows cover fixedly connected to its top surface and the lower connecting ring to its bottom surface. The bellows cover is arc-shaped. A semi-circular hole is opened in the middle of both the upper and lower connecting rings. A groove is symmetrically opened on the outer side of the upper connecting ring. A moving block is slidably connected in the groove. An L-shaped hook plate is fixedly connected to the outer side of the moving block. A guide ladder is symmetrically fixedly connected to the outer side of the lower connecting ring.

[0009] Preferably, the mounting protrusions are symmetrically distributed on both sides of the wiring port, and the upper and lower synchronous gears are meshed and connected, and the synchronous gears are fixedly connected to the connecting shaft.

[0010] Preferably, the bottom of the guide ladder has a guide slope and a stabilizing plane, the length of the groove is longer than the guide ladder, and the bottom of the L-shaped hook plate is engaged with the guide ladder.

[0011] Preferably, a protective cover is fitted over the mounting protrusion, the connecting shaft is connected through the protective cover, and the protective cover is fixedly connected to the outside of the outdoor lithium battery body.

[0012] Preferably, one end of the groove is aligned with one end of the guide ladder strip that has a stable plane.

[0013] Preferably, the two semicircular holes can form a wire hole of a common diameter.

[0014] Preferably, a rain shield is provided above the semi-circular hole, and the top of the rain shield is rotatably connected to the top of the upper connecting ring.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This outdoor lithium battery waterproof device facilitates wiring through the synchronous opening and closing of the upper and lower connecting rings and can automatically reset and close. When closed, it can completely cover the wiring port to prevent rainwater from seeping in. The hydrophobic coating on the contact surface, the hemispherical cover, and the drain outlet assist in waterproofing. The L-shaped hook plate and guide ladder strip interlocking design increases the sealing performance, and the protective cover ensures its stable operation. The specific details are as follows:

[0016] 1. The upper and lower connecting rings open and close synchronously via a belt drive structure, facilitating wiring operations. The upper connecting ring, being heavier than the lower one, automatically resets and remains closed under its own weight, simplifying operation. When closed, the upper and lower connecting rings, along with the bellows cover, completely enclose the wiring port, effectively preventing rainwater from seeping into the connection gap between the cable and the port. A hydrophobic coating on the contact surfaces of the upper and lower connecting rings further enhances waterproofing. The hemispherical cover formed by the upper and lower connecting rings and the bellows cover, or vice versa, along with the drainage outlet at the bottom of the lower connecting ring, automatically drains any small amount of rainwater that seeps in, preventing backflow. Furthermore, the interlocking design of the L-shaped hook plate and guide ladder, through elastic deformation, tightens the upper and lower connecting rings, increasing sealing. The protective cover outside the mounting protrusion prevents rainwater or dust from interfering with the synchronous gear transmission, ensuring stable operation of the waterproof components. The wiring port and wire hole are coaxial, preventing wire bending.

[0017] 2. The rain guard can magnetically adhere to the surfaces of the upper and lower connecting rings, fitting snugly above the wiring port. This design effectively prevents rainwater from flying obliquely into the wiring port through the wire holes. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 The present invention provides a technical solution: an outdoor lithium battery waterproof device, including an outdoor lithium battery body 1, with a lighting lamp 101 and a wiring port installed on one side of the outdoor lithium battery body 1; the outdoor lithium battery body 1 is an existing device.

[0026] A waterproof component 2 is provided on the outside of the wiring port. The waterproof component 2 includes a pair of mounting protrusions 201. A connecting shaft 202 is symmetrically rotatably connected to one side of the mounting protrusions 201. A synchronous gear 203 is commonly fitted on the outside of the connecting shafts 202. An upper connecting ring 204 and a lower connecting ring 205 are respectively fixedly connected to the ends of the upper and lower connecting shafts 202 away from the mounting protrusions 201. Among them, a bellows cover 206 is fixedly connected to the top surface of the upper connecting ring 204 and the bottom surface of the lower connecting ring 205. The bellows cover 206 is arc-shaped. Each lower connecting ring 205 has a semi-circular hole 207 in the middle, and the outer side of the upper connecting ring 204 has symmetrically formed grooves 208. A moving block 209 is slidably connected within the groove 208, and an L-shaped hook plate 210 is fixedly connected to the outer side of the moving block 209. Guide ladder strips 211 are symmetrically fixedly connected to the outer side of the lower connecting ring 205. By lifting the upper connecting ring 204, a belt drive structure composed of two connecting shafts 202 and a synchronous gear 203 is used to synchronously rotate the lower connecting ring 205 downwards, thereby exposing the wiring port and enabling wiring. After releasing the upper connecting ring 204, the total weight of the upper connecting ring 204 is greater than that of the lower connecting ring 205. Under its own weight, the upper connecting ring 204 rotates downward and drives the lower connecting ring 205 to reset, while simultaneously combing the wires until the upper connecting ring 204 and the lower connecting ring 205 are joined together and automatically maintain a static closure. Finally, the moving block 209 is moved, causing the L-shaped hook plate 210 to slide along the groove 208 until the L-shaped hook plate 210 moves along the guide slope 2111 and then moves to the stable plane 2112. During this process, the guide ladder 211 and the L-shaped hook plate 21... The upper connecting ring 204 and the lower connecting ring 205 will undergo slight elastic deformation, and the deformation force will tighten the splicing effect of the upper connecting ring 204 and the lower connecting ring 205, increasing the sealing performance; the L-shaped hook plate 210 and the guide ladder 211 are both made of plastic; when closed, the upper connecting ring 204, the lower connecting ring 205 and the bellows cover 206 can completely cover the wiring port, preventing rainwater from seeping into the connection gap between the cable and the wiring port when used outdoors; at the same time, the basic limiting function of the upper connecting ring 204 and the lower connecting ring 205 can prevent the cable from shaking and causing the two to separate and open, allowing rainwater to enter.

[0027] Mounting protrusions 201 are symmetrically distributed on both sides of the connection port. Two upper and lower synchronous gears 203 mesh and are fixedly connected to the connecting shaft 202. The synchronous counter-rotation of the synchronous gears 203, combined with the fact that the total weight of the upper connecting ring 204 is greater than that of the lower connecting ring 205, means that when both the upper and lower connecting rings 204 are in a horizontal state, the downward rotation tendency of the upper connecting ring 204 is blocked by the upward rotation tendency of the lower connecting ring 205, automatically maintaining a closed state. The contact surfaces of the upper connecting ring 204 and the lower connecting ring 205 are coated with a hydrophobic coating to assist in waterproofing. The upper connecting ring 204 and the bellows cover 206 or the lower connecting ring 205 and the bellows cover 206 form a hemispherical cover. The bottom of the lower connecting ring 205 has several drainage holes to automatically drain a small amount of rainwater that seeps in. Since the drainage holes face downwards, rainwater backflow will not occur.

[0028] The bottom of the guide ladder 211 is provided with a guide ramp 2111 and a stabilizing plane 2112. The length of the groove 208 is longer than that of the guide ladder 211. The bottom of the L-shaped hook plate 210 is engaged with the guide ladder 211. The L-shaped hook plate 210 provides tension as it moves along the guide ramp 2111. However, when it moves to the stabilizing plane 2112, the friction makes the L-shaped hook plate 210 unable to continue to move freely, and the engagement between the L-shaped hook plate 210 and the guide ladder 211 makes them inseparable.

[0029] A protective cover 212 is fitted over the mounting protrusion 201. The connecting shaft 202 is connected through the protective cover 212. The protective cover 212 is fixedly connected to the outside of the outdoor lithium battery body 1. The protective cover 212 can prevent rain or dust from interfering with the smooth transmission of the synchronous gear 203.

[0030] One end of the groove 208 is aligned with one end of the guide ladder 211 where a stable plane 2112 is provided; when the L-shaped hook plate 210 slides to the end where the groove 208 is aligned with the guide ladder 211, the locking operation is completed.

[0031] Two semi-circular holes 207 can form a wire hole of a common diameter.

[0032] A rain shield 3 is provided above the semi-circular hole 207. The top of the rain shield 3 is rotatably connected to the top of the upper connecting ring 204. The surface of the rain shield 3 is coated with a magnetic coating. When the wiring port does not need to be wired, the rain shield 3 is magnetically attracted to the surfaces of the upper connecting ring 204 and the lower connecting ring 205 to prevent rainwater from flying obliquely into the wiring port through the wire hole.

[0033] Working principle: Before using this type of outdoor lithium battery waterproof device, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 5 As shown, when wiring is required, the upper connecting ring 204 is lifted. Since the two connecting shafts 202 and the synchronous gear 203 form a belt drive structure, the lower connecting ring 205 will rotate downward synchronously, exposing the wiring port and facilitating wiring operations.

[0034] After wiring is completed, loosen the upper connecting ring 204. Because its total weight is greater than that of the lower connecting ring 205, the upper connecting ring 204 rotates downward under its own weight and drives the lower connecting ring 205 to reset. At the same time, comb the wires until the upper connecting ring 204 and the lower connecting ring 205 are joined together and automatically maintain a static closed state.

[0035] Next, the moving block 209 is moved, causing the L-shaped hook plate 210 to slide along the groove 208. After passing the guide slope 2111 of the guide ladder 211, it moves to the stable plane 2112. During this process, both undergo slight elastic deformation, tightening the splicing of the upper and lower connecting rings and increasing the sealing performance. After closing, the upper connecting ring 204, the lower connecting ring 205, and the bellows cover 206 completely cover the wiring port, preventing rainwater from seeping in. Furthermore, the basic limit of the upper and lower connecting rings can prevent the cable from separating due to vibration.

[0036] When the connection port does not require wiring, the rain shield 3 is magnetically attracted to the surfaces of the upper and lower connecting rings through the magnetic coating, preventing rainwater from flying in at an angle.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
