Description

Technical Field

[0002] With societal development, the usage rate of new energy batteries is increasing. New energy batteries are electrochemical devices that can be charged and discharged to store clean energy, bringing significant convenience to people's lives. To improve battery safety, protective casings are used. These casings provide waterproofing and dustproofing. With increasing outdoor activities, the demand for outdoor batteries is constantly rising, making waterproof and dustproof battery casings increasingly important. Existing waterproof and dustproof casings typically consist of an upper casing, a lower casing, connecting bolts, and a handle located at the top of the upper casing.

[0003] Existing waterproof and dustproof enclosures still have the following problems during use:

[0004] First, the connection between the battery wires and the casing has a defect of being movable and not sealed. There is still a risk of water leakage during use or pulling. Furthermore, the wire connection is prone to loosening after repeated pulling and use, posing a certain safety hazard.

[0005] Secondly, the connection between the upper and lower housings is not airtight during use. Since the battery case handle is usually located at the top of the upper housing when used outdoors, the weight of the battery itself may cause a gap between the lower and upper housings when lifting or moving the battery, which will affect the waterproof and dustproof effect.

[0037] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be arbitrarily combined with each other.

[0038] like Figure 1-3 As shown, this application proposes a waterproof and dustproof plastic casing for new energy batteries. The plastic casing includes an upper casing 1 and a lower casing 2; wherein the upper casing 1 and the lower casing 2 are joined together by a first sealing member to form a sealed casing. A battery can be placed inside the sealed casing. Specifically, the sealed casing is provided with a wire protection mechanism 7, and the wire protection mechanism 7 is provided with a wire 8, which can be electrically connected to the battery inside the sealed casing; the wire protection mechanism 7 is provided with a compression component; when the wire 8 is subjected to tension, the compression component can engage with the wire 8 to restrict the movement of the wire 8 in the direction of tension. The wire protection mechanism 7 designed in this application can restrict the movement of the wire 8 in the direction of tension to prevent the wire 8 from loosening on the wire protection mechanism 7, thereby preventing the wire from loosening between the wire and the casing, and thus improving the safety of battery use.

[0039] like Figure 1 and Figure 3 As shown, the outer casing is provided with at least one wire protection mechanism 7, wherein the number of wire protection mechanisms 7 corresponds to the number of wires 8. Preferably, the wire protection mechanism 7 can be provided at the joint between the upper casing 1 and the lower casing 2, which facilitates installation and disassembly. Specifically, by protecting and limiting the wires 8, the wire protection mechanism 7 can prevent or reduce loosening between the wires and the outer casing, and at the same time can play a role in dustproofing and waterproofing.

[0040] like Figure 7-13 As shown, in some embodiments, the wire protection mechanism 7 includes a protective cover and a sealing sleeve 79. The protective cover has an opening; the sealing sleeve 79 is fixedly sleeved on the conductor 8 and sealed within the opening. The sealing sleeve 79 is preferably made of silicone, which increases resistance and provides good cushioning and sealing. The sealing sleeve 79 is embedded within the opening, forming an interference fit, providing the first layer of protection. Further, the compression assembly includes a first compression assembly and a second compression assembly; the first compression assembly is disposed on the sealing sleeve 79, and the second compression assembly is disposed on the protective cover; the first and second compression assemblies are joined together. Specifically, when the conductor 8 is subjected to tensile force, the first and second compression assemblies can compress each other to restrict the movement of the sealing sleeve 79, thereby limiting the loosening of the conductor 8 and the outer shell, and the conductor 8 and the protective cover under tension, thus providing protection.

[0041] like Figure 7-13As shown, in some embodiments, a first extrusion assembly is disposed at one end of the sealing sleeve 79 located inside the protective cover, and a second extrusion assembly is disposed on the inner wall of the protective cover. The first extrusion assembly includes an extrusion cover 76 and a transmission plate 77. The transmission plate 77 is fixedly disposed at the end of the sealing sleeve 79 away from the inner wall of the protective cover; the extrusion cover 76 is fixedly disposed on the side of the transmission plate 77 facing the inner wall of the protective cover. Further, the second extrusion assembly includes two limiting flaps 75, which are respectively disposed circumferentially on the sealing sleeve 79, i.e., the limiting flaps 75 are fixedly disposed on the inner wall of the protective cover and located on one side of the sealing sleeve 79. Specifically, when the first extrusion assembly is subjected to pulling force, the extrusion cover 76 moves towards the inner wall of the protective cover and compresses the two limiting flaps 75 to contract against each other, clamping them onto the sealing sleeve 79, thereby restricting the movement of the sealing sleeve 79 and preventing the wire 8 from loosening. Preferably, the limiting flap 75 is made of silicone or rubber, which allows for easy extrusion and deformation, while increasing the friction with the sealing sleeve 79, thereby achieving a good limiting and sealing effect.

[0042] like Figure 7-13 As shown, in some embodiments, the extrusion cover 76 is a hollow frustoconical extrusion cover, that is, the extrusion cover 76 has a frustoconical structure. The smaller end of the frustoconical extrusion cover faces the inner wall of the protective cover. Two limiting petals 75 are fitted together to form a hollow frustoconical limiting sleeve, that is, the two limiting petals 75 are spliced ​​together to form a frustoconical limiting sleeve, which has a frustoconical structure. Specifically, the smaller end of the frustoconical limiting sleeve is movably disposed inside the frustoconical extrusion cover, preferably abutting against the inside of the frustoconical extrusion cover. By adopting the above scheme, through the ingenious design of the frustoconical extrusion cover and the frustoconical limiting sleeve engaging with each other, they can be squeezed and deformed under tensile force, thereby firmly clamping them in the sealing sleeve, preventing the sealing sleeve from loosening under force, and achieving a sealing function while providing protection.

[0043] like Figure 7-13 As shown, in some embodiments, the protective cover includes an upper cover 71 and a lower cover 72, wherein the upper cover 71 and the lower cover 72 are joined together by a second sealing member to form a sealed cover. Preferably, the opening of the protective cover is provided on the mating surface of the upper cover 71 and the lower cover 72, which facilitates the installation of the sealing sleeve 79. Specifically, the first limiting flap is provided on the inner wall of the upper cover 71, and the second limiting flap is provided on the inner wall of the lower cover 72, realizing alignment and facilitating assembly. It should be noted that with the above design, when the two limiting flaps 75 squeeze and contract against each other, they can simultaneously pull the upper cover 71 and the lower cover 72 to contract against each other, forming a better seal. Furthermore, the root of the wire 8 is not straightened, that is, the wire 8 has a bent portion, which is housed within the upper cover 71 and the lower cover 72, which can effectively increase the tensile resistance and improve the sealing performance.

[0044] like Figure 7-13As shown, in some embodiments, a limiting ring 78 is also fixedly provided on the sealing sleeve 79. Specifically, the limiting ring 78 fits against the outer wall of the protective cover and clamps the wire 8, thereby restricting the movement of the wire 8. Further, a protective ring 9 is also fixedly sleeved on the wire 8, which is snapped into the through hole at the joint surface of the upper housing 1 and the lower housing 2, serving as a buffer and sealing function. Preferably, the protective ring 9 is made of silicone or rubber material.

[0045] like Figure 1 , 14 As shown in Figure -15, in some embodiments, the first sealing element is a sealing strip 12, which is disposed on the sealing groove 13 of the mating surface of the upper housing 1 and the lower housing 2, and can effectively form a seal between the upper housing 1 and the lower housing 2. Preferably, the sealing strip 12 is made of silicone material. Specifically, the sealing strip 12 is disposed in the circumferential direction of the upper end face of the lower housing 2, and the sealing groove 13 is disposed in the circumferential direction of the lower end face of the upper housing 1. When the upper housing 1 and the lower housing 2 are joined, the sealing strip 12 can be embedded in the sealing groove 13, thereby forming an effective seal when the upper housing 1 and the lower housing 2 are joined. Of course, the sealing strip 12 is disposed in the circumferential direction of the lower end face of the upper housing 1, and the sealing groove 13 is disposed in the circumferential direction of the upper end face of the lower housing 2, which can also achieve installation and sealing, and will not be described in detail here.

[0046] like Figure 1 , Figure 9 As shown, in some embodiments, the second sealing element is a sealing ring 74, which is made of silicone material. The sealing ring 74 is disposed on a groove 73 on the mating surface of the upper cover 71 and the lower cover 72, effectively forming a seal between the upper cover 71 and the lower cover 72. Specifically, the sealing ring 74 is disposed circumferentially on the lower end face of the upper cover 71, and the groove 73 is disposed circumferentially on the upper end face of the lower cover 72. When the upper cover 71 and the lower cover 72 are engaged, the sealing ring 74 can be embedded within the groove 73, thereby forming an effective seal. Similarly, the sealing ring 74 is disposed circumferentially on the upper end face of the lower cover 72, and the groove 73 is disposed circumferentially on the lower end face of the upper cover 71, which also achieves installation and sealing; further details are omitted here.

[0047] like Figure 1-6 As shown, in some embodiments, the sealed outer shell is provided with an upper lifting member 3 and a lower support member 6. The upper lifting member 3 is disposed on the upper shell 1, specifically located at the middle position of the upper surface of the upper shell 1, thus facilitating the removal of the plastic shell. The lower support member 6 is disposed on the lower shell 2 to support the lifting of the lower shell 2. Furthermore, the upper lifting member 3 and the lower support member 6 can be detachably joined together, thereby enabling the entire plastic shell to be lifted.

[0048] like Figure 1-6As shown, in some embodiments, connecting blocks 4 are respectively provided on the outer side walls of the upper shell 1 and the lower shell 2, so that the connecting blocks 4 on the upper shell 1 and the lower shell 2 can be connected together by connecting members. Preferably, the connecting members can be bolts 5 and nuts 11. The connecting blocks 4 are provided with through grooves 10. Further, the lower support member 6 includes a concave rod 61, which is sleeved on the lower shell 2 and passes through the through groove 10 on the connecting block 4 to connect with the lifting member 3. This can stably connect the lower shell 2 and the upper shell 1 together, and there will be no slippage or imbalance during lifting. With the above solution, the upper shell and the lower shell are connected by connecting blocks, which can easily achieve a fixed connection; while supporting the lower shell, the concave rod passes through the connecting block to connect with the lifting member, which can play a role in balance support and positioning.

[0049] like Figure 1-6 As shown, in some embodiments, the lifting member 3 includes an I-shaped plate 31 and a telescopic assembly. The two sides of the I-shaped plate 31 are fixedly disposed at the middle position of the upper end face of the upper housing 1 by protrusions 33. The protrusions 33 are fixedly connected to the upper housing 1 by bolts 5. A handle 32 is provided on the I-shaped plate 31. Further, the telescopic assembly is symmetrically disposed on the I-shaped plate 31, and both ends of the telescopic assembly can be detachably connected to the concave rods 61 on both sides of the sealing housing via telescopic movement. Specifically, the telescopic assembly includes a bidirectional lead screw 34 and a connecting sleeve 37. The bidirectional lead screw 34 is horizontally disposed through the I-shaped plate 31 and can rotate on the I-shaped plate 31. The connecting sleeve 37 is respectively drivenly disposed at both ends of the bidirectional lead screw 34 and threadedly connected to the bidirectional lead screw 34. Specifically, by rotating the bidirectional lead screw 34, the connecting sleeve 37 can be driven to telescopically move, thereby being able to insert into the rectangular groove 63 of the concave rod 61, realizing vertical positioning and detachable connection of the two concave rods 61. Furthermore, the telescopic assembly also includes a guide rod 35, which is disposed on one side of the bidirectional lead screw 34 to guide the telescopic movement of the connecting sleeve 37. More specifically, one end of the guide rod 35 is disposed on the connecting sleeve 37, and the other end of the guide rod 35 is telescopically disposed within the guide hole of the I-beam plate 31, thereby guiding the telescopic movement of the connecting sleeve 37 when the bidirectional lead screw 34 rotates. Furthermore, an anti-detachment block 36 is provided at the end of the guide rod 35 that passes through the guide hole of the I-beam plate 31 to prevent the guide rod 35 from detaching from the I-beam plate 31.

[0050] like Figure 1-6 As shown, in some embodiments, the lower support 6 includes two sets of concave rods 61, the bottoms of which are laterally supported on the bottom surface of the lower housing 2. A trailing rod 62 is provided longitudinally at the bottom of each of the two sets of concave rods 61, and the trailing rod 62 is longitudinally supported on the bottom surface of the lower housing 2. Preferably, there can be two or three trailing rods 62 to maximize longitudinal support for the lower housing 2.

[0051] like Figure 1-6 As shown, this application proposes a waterproof and dustproof plastic shell for new energy batteries, and the specific usage process and principle are as follows:

[0052] Place the battery inside the lower housing 2, then place the upper housing 1 on top of the lower housing 2, so that the sealing strip 12 at the upper end of the lower housing 2 is engaged in the sealing groove 13 at the lower end of the upper housing 1. Then, tighten the nuts 11 by inserting the bolts 5 through the two connecting blocks 4. The upper ends of the two concave rods 61 pass through the through slots 10 on the two sets of connecting blocks 4 on both sides. Then, rotate the two bidirectional lead screws 34 in sequence. Under the guidance of the guide rod 35, the two sets of connecting sleeve rods 37 are inserted into the rectangular slots 63 at the upper ends of the two concave rods 61, so that the lifting member 3 and the lower support member 6 together provide positioning and support for the upper housing 1 and the lower housing 2. When the battery is moved or lifted, the force is distributed between the lifting member 3 and the lower support member 6, thus preventing the connection between the lower housing 2 and the upper housing 1 from loosening or leaking gaps, ensuring the stability of the connection between the upper housing 1 and the lower housing 2, and thus improving the dustproof and waterproof effect.

[0053] Furthermore, when the battery is placed into the plastic casing, the wire 8 connected to its end passes through the through hole, and the protective ring 9 is secured in the through hole. At the same time, the sealing sleeve 79 is secured in the opening at the outer end of the upper cover 71 and the lower cover 72, and the limiting ring 78 is attached to the outer surface of the upper cover 71 and the lower cover 72. Since the upper cover 71 is disposed on the upper housing 1 and the lower cover 72 is disposed on the lower housing 2, when the upper housing 1 and the lower housing 2 are engaged, the upper cover 71 and the lower cover 72 are also engaged with each other, and the sealing ring 74 is embedded in the slot 73, achieving effective sealing. When charging with wire 8, if wire 8 is pulled improperly, the sealing sleeve 79 will also be pulled outward. After being pulled, the sealing sleeve 79 will drive the transmission plate 77 to move in the direction of the pull. The movement of the transmission plate 77 will drive the compression cover 76 to move, and then the compression cover 76 will squeeze the two limiting petals 75. Under the action of the opposing compression force, the two limiting petals 75 will move closer to each other, and finally make the upper cover 71 and the lower cover 72 more tightly pressed together, further clamping the pulled sealing sleeve 79, so that the wire 8 remains stable when pulled and will not be continuously pulled outward, thus ensuring the stability of the connection between the wire 8 and the battery. At the same time, the upper cover 71 and the lower cover 72 maintain a stable connection state when the wire 8 is pulled, thus ensuring the sealing effect at the root of the wire 8 connection, and achieving excellent dustproof and waterproof effect.

[0054] The waterproof and dustproof plastic casing for new energy batteries proposed in this application has the following technical advantages:

[0055] (1) The waterproof and dustproof plastic shell for new energy batteries proposed in this application has a wire protection mechanism on the sealed shell. The wire protection mechanism can restrict the movement of the wire along its pulling direction to prevent the wire from loosening on the wire protection mechanism, thereby playing a stable sealing role, significantly improving the dustproof and waterproof effect of the plastic shell, and improving the safety of battery use.

[0056] (2) The waterproof and dustproof plastic shell for new energy batteries proposed in this application increases the resistance to pulling by cleverly designing the first extrusion component and the second extrusion component to squeeze each other during pulling, so as to limit the wire from being pulled out continuously during pulling, thereby ensuring the stability of the connection between the wire and the battery; at the same time, the upper cover and the lower cover maintain a stable joint state when the wire is pulled, thereby ensuring the sealing effect at the root of the wire connection and achieving excellent dustproof and waterproof effect.

[0057] (3) The waterproof and dustproof plastic shell for new energy batteries proposed in this application uses an upper lifting part and a lower support part to position and support the plastic shell. The force is more balanced when the plastic shell moves and is lifted. The connection between the lower shell and the upper shell does not easily loosen or leak gaps, ensuring the stability of the connection between the upper shell and the lower shell, thereby improving the dustproof and waterproof effect.

[0058] Although the embodiments disclosed in this application are as described above, the content is merely for the purpose of facilitating understanding of this application and is not intended to limit this application. Any person skilled in the art to which this application pertains may make any modifications and changes in the form and details of the implementation without departing from the spirit and scope disclosed in this application; however, the scope of patent protection of this application shall still be determined by the scope defined in the appended claims.
